General information

By purchasing this system you have acquired a modern and effi cient heating system. Ongoing qua-lity controls and improvements as well as functional checks at the factory guarantees you a technically perfect equipment.

Please read through this documentation carefully.It contains important information for correct in-stallation and safe and economical operation of the system.

1.1. Standards and direct ives

For the installation of the heatpump follow all relevant national and international piping- and installation re-gulations and the instructions given of this Installation instruction.

Amongs others comparing the following: - the general rules for accident prevention and safety regulations

- the regulations for environmental protection - the provisions/regulations of the professional asso-ciations.

- the effective laws, standards, guidelines and regu-lations e.g. DIN, EN, DVGW, VDI and VDE

- regulations of the local suppliers/supply companies

1.2. Safety instruct ions

Installation and maintenance work can be hazardousdue to high system pressure, high temperatures and live parts and may only be carried out by specialist staff. Heat pumps may only be installed by competent specialist staff and commissioned by a customer service company trained to do so by iDM Energiesys-teme GmbH.When working on the heat pump, the system must be shut-off and secured against unintentional restart.In addition, all safety instructions in the relevant do-cumentation, stickers on the heat pump itself and all other applicable safety regulations must be observed.

1. General information

1.3. Storage

Heat pump components may not be stored outdoors. Heat pumps should not be stored in wet rooms or in potentially dust rooms.

1.4. Instal lat ion room

The TERRA SWM should be installed in a frost-proof room. The Room temperature should be between 5°C and 25°C!

To minimize vibrations and noise, the heat pump must be isolated from the building structure. Basically, setting up of the heat pump on light weight design ceilings must be avoided. In case of a fl oating screed, the screed and the sound damping have to be omitted around the heat pump.

The installation in wet rooms or in potentially dust or explosion-endangered rooms is not allowed.

Gas from refrigerants in plant rooms must not escape into vicinal rooms, stair rooms, courtyards, walks or into the drainage system of the building. The gas has to be channelled off safely!

In case of danger, the plant room has to be evacua-ted immediately.

In case a natural ventilation is not possible, a me-chanical ventilation has to be provided. A mechanical ventilation has to be equipped with an independent emergency control outside of the machine room near the door.

Heat pumps should not be installed in rooms with high electromagentic infl uences from other installations!

If the minimum size of the installation room falls below the required value as described in the technical data, the room must be designed as an machine room accor-ding to EN 378!


General information

1.5. Sound emission

The TERRA SWM is very quiet in operation thanks to the design. It is however important that the boiler room is situated as far as possible from noise-sensitive living areas. A well-closing door should be installed.

1.6. Instal l ing addit ional components

The installation of additional components which have not been tested with the equipment may impair func-tion. No warranty or liability is assumed for damages resulting from this.

1.7. Construct ion dr ying and screed heat ing

The heat pump is not designed for the increased heat requirements when drying out construction work or heating plaster or screed. This must be covered by equipment to be provided by the customer, if requi-red.

1.8. Cleaning

If necessary, the TERRA SWM can be cleaned with a damp cloth. The use of cleaning agents is not re-commended.

1.9. Ser vic ing and maintenance

Regular maintenance, control and servicing of all system components guarantees safe and economi-cal operation in the long term. To achieve this, we recommend a maintenance cotract with the relevant customer service company. Only original spare parts which meet the requirements of iDM may be used!

1.10. Ser vice

For technical information please contact your relevantiDM customer service department.

1.11. Warranty and guarantee

Warranty and guarantee conditions are included in the purchased documents. For questions please contact your relevant customer service department.

1.12. Disposal

Heatpumps are electrical equipment made from high valuable materials, which are not allowed to be disposed like normal household garbage, but have to be disposed professional and proper according the regulations of the local authorities.A non-proper disposal can cause, apart from sanc-tions for the violator, environmental damages and harm for your health.This device is characterized according to the euro-pean directive 2012/19/EU on waste electrical and electronic equipment (Waste electrical and electronic equipment - WEEE). The guideline provides the framework for an EU-wide return and recycling of oldequipment.Dispose the device properly and do not damage the pipes of the refrigerant circuit.

On the refrigerant side the TERRA SWM is „hermetically tight“.




2. Description

2.1. Descr ipt ion

The iPump is a brine-water heat pump with a Scroll-compressor with Inverter-technology.The microprocessor controller NAVIGATOR 2.0 en-sures effi cient operation of the heat pump. The heat pump system is controlled as needed and is equipped with a variety of monitoring-, security- and reporting functions.By default, one heating circuit can be regulated. Sys-tems up to six heating circuits can be realized with optional heating circuit extension modules. A colored 7“ touch display simplifi es the operation of the heat pump.

The connections of the brine lines are inside the heat pump. The connections for heating lines are also inside. All connections can be feed out either on the right or left side of the heat pump.The LAN-connection, the cable inlet for the sensors and the power supply are on the backside. The USB-port is integrated in the front part and is closed by a stopple when delivered.

TERRA SWM is available with HGL or with HGL and process reversal (P). Thereby the heat pump can be used for cooling.

The TERRA SWM heat pump is working with the sa-fety refrigerant R410A. It circulates in an closed circuit when installed and commissioned properly, meaning that there is no environmental impact.

The lower the maximum fl ow temperature is set, the higher is the effi ciency of the heat pump.

2.2. Appl icat ion range

The TERRA SWM can be used for monovalent hea-ting and cooling of single and multiple dwellings with ground heat utilisation.In this case the building should be equipped with low-temperature heating (e.g. underfl oor heating, wall heating, low temperature radiator heating).The heat pump may only be used for domestic and not for purely commercial operation!

Description

2.9. Per formance data - cool ing according to EN 14511

In order to guarantee a correct cooling mode, when working with unregulated direct-heating circles (without cooling buffer), the following 3 requirements have to be fulfi lled:

1. To ensure the minimum volume of heating site, appropriate zones have to remain open all the time. Minimum volume 80 lt.

2. To ensure the minimum fl ow rate of heating site, appropriate zones have to remain open all the time. Minimum fl ow rate 1.01 m³/h

3. To ensure the minimum cooling output rate of distribution system, appropriate zones have to remain open all the time. The minimum cooling output rate is 70 % of the minimum cooling output power of the heat-pump at S30°C/W18°C. Minimum cooling power consumption 2.8 kW

All 3 requirements must be fulfi lled independently. This is possible applying the NAVIGATOR Pro. The entire distribution system has to fulfi ll the 3 mentioned requirements.

To ensure a large cooling demand, the cooling limit has to be set as high as possible.

2.10. L imits of useThe TERRA SWM must only be used with the heat media of brine or groundwater. No other heat media are permissible. In addition, the heating of other fl uids as heating water is not permitted (for heating water quality, see page 29).

Heat pumps are by nature subject to limits of use based on pressure and temperature (see diagram). It is not permissible to operate the TERRA SWM out-side these limits of use.

Note:The following safety devices are included to protect the heat pump against faults:- electronic high- and low pressure monitoring - Flow-maximum temperature limiter with automati-cally reset via the NAVIGATOR 2.0 control

Transport

In order to avoid damages during transport, the heat pump should be transported to its fi nal installation site in packed condition on the wooden palett with a forklift or hand lift truck.

The components and the tubing of the heating- and heat source site must never be used to transport the heat pump.

When heat pump is lifted from the wooden palett, there is a risk of tilting. Therefore, the device must be lifted and secured with a suffi cient number of persons. The weight of the heat pump must be considered!

Transport of the heat pump via stairways

The heat pump can be lifted down the stairways step by step with a sack barrow. A suffi cient number of persons for securing the device during the transport shall be present. If the heat pump must be transported without the wooden pallet and the protective wooden crate, it is important that there will be no damage on the housing.

4. Assembly and hydraulic installation

4.1. Assembly

TERRA SWM heat pumps must be installed in a frost-protected room by an approved specialist fi rm. The room temperature must be between 5°C and 25°C.

If the minimum size of the installation room falls belowthe required value, the room must be designed as anmachine room according to EN 378. It is not permis-sible to install the equipment in wet or dusty rooms orrooms where there is a risk of explosion.

In order to avoid structure-borne sound transmissi-ons, the heat pump must be installed on a horizontal, level and weight-bearing surface (concrete plate or similar). In the case of fl oating screed, the screed and the impact sound insulation must be recessed around the heat pump to ensure low noise levels when the heat pump is operating (see adjacent illustration).The heat pump, must be put on the delivered noi-se insulation pad. When delivered, the pads are located on the machine.CAUTION:Do not confuse with packaging material!

The connections for brine- fl ow and return are inside of the TERRA SWM and lead through out either on the right or left side. The connections for heating- fl ow and return are also inside the heat pump and can also lead out either on the right or left side.

The cable inlet for the sensors, the main current and the LAN connection are on the backside of the heat pump.

The relevant laws, regulations and standards must beobserved, in particular EN 378 parts 1 and 2 as well as BGR 500.

For maintenance work a gap of 600 mm must be accomplished at the front and depending of the con-nection of the brine pipes, on the right or left side of the heat pump. As well for the main power supply, the sensors and for the LAN-interface on the backside of the heat pump, a distance of at least 200 mm to the wall has to be respected.

5. Electrical assembly

5.1. Power supply

The electrical power supply must be made by a quali-fi ed person and must be registered by the local elec-tricity company. The executive electrical company, is responsible for the standard-compliant connection to the electrical installation and the applied safety measure. Before commissioning all clamps must be controlled and if necessary they must be retighten. For electrical details please see the relevant wiring diagram.

The main supply voltage at the terminals of the heat pump must be 400 V ± 10%. The dimensions of the connecting cables must be checked by the executive electrical company.

A fault-current circuit breaker for the heat pump is not required. The connection to the protective measure „protective multiple earthing“ is suffi cient. If never-theless the protective measure „fault-current circuit breakers“, dispatched by the executive electric com-pany, a separate fault-current circuit breaker for the heat pump is recommended. This must be designed as an all current sensitive Type B (IΔN ≥ 30mA). The specifi ed FI-types related to the heat pump excluding externally connected components (see Installation instructions, data sheets).

For the main current circuit as a result of the occur-ring starting currents, circuit breakers with a tripping characteristic curve type „C“ or „K“ must be used.

For the control circuit and the optional electric auxilia-ry heater, circuit breakers with a tripping characteristic type „B“ or „Z“ are suffi cient.

The electrical connection- and supply cables must be designed as copper cables.

5.2. EMC compatibi l i ty

For the TERRA SWM, separate cable entries for the main power supply and for the sensors have been designed to avoid problems in the fi eld of Electro- Magnetic Compatibility.

It is especially in the area of responsibility of the elec-trical company to avoid possible coupling paths when creating the electrical installation.

EMC-faults can have different effects: - Short-term measurement faults - Permanent measurement faults - Short-term interruption in data connections - Permanent interruption in data connections - Data losses - Damage to equipment

5.3. Disassembly the cover

Before the electrical connection of the heat pump the cover has to be removed. First, the front part with the NAVIGATOR 2.0 touch display has to be dismount. To remove the front panel, the interlocking device must be opened with a screw driver or a pointed object. The interlocking device is behind the white cover, around 1 cm above the edge of the unit. By pressing the locking bolt, the lock of the front panel will be released.

When removing the front panel, make sure that the connection cable between the control panel and the motherboard is disconnected.

The cover is fi xed with two screws. After removing the screws, the cover can be pulled forward. Now, the cover can be lifted up and the earthing cable can be removed. Afterwards the connection terminals are freely accessible.

Consider the note for opening!

Disconnect the cable to the control panel

Remove the fastening screws

Pull the cover forward and remove it

5.5. Connect ion the central uni t

The assignment of the inputs on the central unit can be found in the electrical wiring diagram of the heat pump.

Sensor designThe sensor positions are shown in the relevant installation diagram. Reliable functioning can only be ensured by correct positioning and a good heat transfer (heat conducting paste).If necessary, the sensors can be extended using appropriate cables. It must be ensured that the connection is clean and corrosion-free. Sensor lines should be run separately from mains cables, (see EMC issue!).It is recommended to use shielded cables!

Sensor equipmentMost of the sensors are allready installed in the heat pump. The following sensors are necessary in all cases and must be installed external: - Outside sensor B32 - Heating buffer sensor B38 - Flow sensor heating circuit A B51 - Sensor warm water station B42 - Hygienik sensor B41

Flow temperature sensorThe fl ow temperature sensors for the heating circuits used are required in every case. They are fi tted onto the relevant fl ow lines and connected according to the connection plan.The fl ow sensors for heating circuits C-G are connec-ted to the relevant heating circuit expansion module. (For more information, see installation instruction for expansion module).

Assignment of the outputsThe assignment of the outputs is carried out accor-ding to the wiring diagram of the heat pump.

System earthingWhen the protective conductor is connected correct-ly, the electrical panel and the heat pump casing are earthed. After all maintenance work, ensure that the potential equalisation has been restored correctly.

Composite signal zone valvesThe composite signal zone valve setting generates arequest when one of the zone valves is open. The difference to a room thermostat function is that, inde-pendently of heating or cooling operations, a request is generated when a zone valve contact is closed.

Connection external preselected target value 0-10VFor the connection of the external preselected tar-get value 0-10V the input of the RFF room sensor is used. Over this external 0-10V signal the desired temperature will be indicated to the Navigator over a higher Control system (BMS).

Sensor cables must be routed separately from power supply cables (see EMC com-patibility).

For each TERRA SWM a sensor package is enclosed.

If zone valves are used, you can generatecomposite signal from all zone valves to be able to switch the heating and cooling cir-cuit on and off with the thermostat function.

5.6. Add-on modules for NAVIGATOR 2.0

To extend the functionality of the NAVIGATOR 2.0, different add-on modules are available as accesso-ries and can be connected to the central unit, like the following additional modules:

NAVIGATOR Pro additional boardTo use the iDM single-room control, an additional board must be connected to the touch display of NA-VIGATOR 2.0. The Modbus cable must be connected to the addional board. Now the touch display can also be used for the iDM single-room control.

Heating circuit control module, internalThe internal expansion module permits the control of two additional heating and/or cooling circuits via the NAVIGATOR 2.0. Two mixers and the relevant fl ow sensors, the offset roomstat and the heating circuit pump can be directly connected on the expansion PCB.

Heating circuit control module, externalThe heating circuit control module external, enables the regulation of three additional heating and/or coo-ling circuits via NAVIGATOR 2.0.The heating circuit control module external, allows three mixer circuits to be connected to the respective heating circuit pumps, fl ow sensors and room units. Communication with the NAVIGATOR 2.0 is effected via a CAN bus connec-tion. This allows the NAVIGATOR 2.0 to be placed up to 300 m away. With cascade systems the usage of the external heating circuit control module is not possible.

EIB/KNX ModuleThe EIB/KNX module can be used to connect EIB/ KNX devices to the heat pump. The resulting EIB/ KNX-compliant heat pump can communicate with other EIB/KNX devices, such as sensors and actua-tors, via this module. This enables data such as tem-perature, operating conditions, etc. to be exchanged and processed between the devices.

Add-on module for SolarThe NAVIGATOR 2.0 enables a temperature differen-tial controlled solar charging. A layered solar injection via a plate heat exchanger in the Hygienik is possible with an additional solar plate.

Extension set electric for groundwater pumpFor TERRA SWM with groundwater usage, the ex-tension set electric must be purchased to control the groundwater pump. The extension set is available as an accessory. The installation must be done accor-ding the electrical wiring diagram.

6. Commissioning

Before commissioning the TERRA SWM heat pumps, the heating side and the brine circuit or groundwater side must be checked for tightness, rinsed thorough-ly, fi lled and bled carefully. During transport it can happen that threaded connections can be loosen inside the heat pump by vibrations. To avoid dama-ges on the heat pump and the installation area, it is absolutely necessary that all pipe connections inside the heat pump are tighten. Please check this during commissioning.

Commissioning requirements: - The heating and any storage tank must be fi lled and bled.

- With brine circuit heat pumps, the brine circuit must be rinsed, bled and fi lled with antifreeze (-15°C).

- The expansion vessel on the brine side must be fi lled.

- The corrugated pipe fi tting on the expansion vessel in the heat pump must be retighten during installa-tion.

- The screwing must be checked for tightness during commissioning.

- The insulating hose must be pushed over the termi-nal nut during commissioning.

- The electrical installation must be complete and fuse-protected in line with legal requirements.

- The heat pump may only be switched on if it is fi lled on the refrigerant side and on the heating side, and if the electrical connections has been checked.

- During commissioning, the fl ow temperatures must also be set. The shut-off point 62°C (with refrigerant R410A) should be checked and the set shut-off temperature changed if necessary.

- If the heat pump is to be drained on the heating side, the connection hose on the heat pump return must be disconnected.

- With groundwater pumps, the groundwater outlet alarm must be set during commissioning so that the shut-off is carried out with a water return tempera-ture of 3°C.

Control of the heat source pumpAfter activating the main switch on the heat pump, thecommissioning assistant is started after the language selection. In the start menu for the commissioning as-sistant, the heat source pump can be actuated manu-ally for rinsing and bleeding the brine or groundwater circuit via the NAVIGATOR 2.0.

6.1. Operat ion

The TERRA SWM is switched on and off automatically via the fully automated NAVIGATOR 2.0. For opera-ting and commissioning, see the separate operating and commissioning instructions.Annual inspection and maintenance of the system by customer services is recommended, in particular with regard to preserving warranty claims.

6.2. Faul ts

The TERRA SWM is fi tted with various safety devices so that no damage can be caused to the equipment in the event of faults. If the heat pump does not run, ple-ase check the fault message which will be displayed on the NAVIGATOR 2.0 control display. For more information, please see the NAVIGATOR 2.0 control operating instructions.

If an error occurs several times in succes-sion, please contact your relevant iDM customer service department.Customer service telephone:

TERRA SWM HGL with direct heating circuit

The TERRA SWM HGL is a modulating heat pump. Therefore, it is possible to provide heating circuits directly without a storage tank! An additional pump and a mixing valve for the heating circuit is not necessary. The Hygienik will be provided over the HGL-pipe. An additional expansion tank must be installed in the return of the heating circuit. The overfl ow valve in the heating circuit must be set to give a proportional fl ow to the number of closed zone valves. With this hydraulic and the modulating operation, can be cooled without a cold storage tank. For dew point monitoring, a room humidity sensor and a dew point switch must be installed.

TERRA SWM HGL with mixing circuit and solar

With priority charging, the top reservoir area is charged with the speed-regulated charging pump to the set HGL temperature. In heating mode of the heat pump, too, a partial fl ow with the set HGL temperature is always charged in the upper reservoir area via the HGL exchanger and the HGL valve. This means that the Hygienik is always kept at the correct temperature. The solar system loads fi rst the upper part of the Hygienik 2.0. Due to the high solar temperatures it is recommended to use a hot water station with mixing valve.

The relevant laws, regulations and standards for ma-chine room piping and for heat pump systems must also be observed. - It is essential that a dirt trap is fi tted in the heating return pipe.

- Safety devices and expansion devices for closed heating systems according to EN 12828 must be fi tted.

- Pipe dimensions must conform to the required fl ow volumes (see section „technical data“ in this instal-lation instruction).

- The connection hoses supplied for the heat pump fl ow and return, and for the HGL connection must be installed. The connection hoses can be shor-tened to the desired length, but not shorter than 60 cm. The connection hoses must not be bended!

- Venting options should be fi tted at the highest points of the connection lines and draining options at the lowest points.

- To avoid heat loss, the connection lines should be insulated using suitable material.

8. Heating side installation

Oxygen diffusionWith plastic pipe underfl oor heating or open heating systems which are not diffusion-tight, corrosion may occur on steel parts when using steel pipes, steel radiators or storage tanks due to oxygen diffusion.

Corrosion products can be deposited in the conden-ser and may cause heating losses to the heat pump or high-pressure faults.

For this reason, open heating systems or steel pipe installations in combination with plastic pipe under-fl oor heating which is not diffusion-tight should be avoided.

Heating water qualityDepending on the quality of the heating water, lime scale may occur (adherent coating primarily con-sisting of calcium carbonate) on heat exchanger surfaces in particular, i.e. with a high proportion of calcium hydrogen carbonate there is an increased risk of lime scale forming. For fi lling heating systems, very clear guidelines apply relating to the heating water quality.Specifi cally, European standard EN 12 828, ÖNORM H 5195 and in particular VDI Guideline no. 2035 must be observed and represent the current state of art. You must also check the pH-value of the heating water. It should be between 8 and 9.5.

In heat pumps with process reversal is already compulsory to install a fl ow meter on heating site!For brine machines, the fl ow meter must be connect on the digital input “Error heat source circuit” (see wiring diagram).For groundwater machines, the fl ow meter must be connected serial to the ground-water fl ow meter.

In case an electrical heating element will be installed in the thermal storage tank, an additional safety device must be ins-talled at the thermal storage tank!

Incorrect fl ow rates due to incorrect piping, incorrect valves and accessories or improper pump operation can cause damages!

The system must only be connected to the mains and put into operation if the entire heating system has been fi lled and bled, as otherwise the circulating pumps may run dry.

DescriptionWith this system, plastic pipes Ø25 x 2.3 mm with a length of 100 m each are laid to extract the heat fromthe earth. The brine medium circulates in these pipes. The heat exchange between the brine medium and refrigerant takes place in the evaporator set (stain-less steel plate heat exchanger).

Scope of deliveryDepending on version, the delivery of a surface coll-ector includes, plastic pipes and a connection unit with distributor. The connecting lines between the distributor and the heat pump must be created by client. It is not allowed to use galvanized hoses.

Note: - Only antifreeze approved by iDM Energiesysteme GmbH are permitted for use.

- Brine circuit lines must be fi tted with steam diffusi-on-proof insulation to protect against condensation and ice formation (e.g. Armafl ex).

- When fi lling the brine circuit with antifreeze mixture, the expansion vessel must be fi lled (due to a reduc-tion in volume when cooling in operation).

- The mixing ratio of the brine medium has to be cho-sen for -15° C (= 30 % antifreeze concentration if to much antifreeze is mixed , the specifi c heat capa-city of the brine medium sinks.

The possible heat loss depends on the soil conditions.Basically valid is that: in dry soils the heat loss capa-city goes down, in humid soils it goes up. For 1 kW of heating output of the heat pump you need 30 - 40 m2 soil.The specifi ed surface area required for ground heat pumps relates to the average earth quality (soil, clay). With poor quality earth (gravel), the necessary line length and thus also the surface area should be in-creased and the pipes embedded in fi ne-grain sand (cable sand 0.3 to 0.5 mm).For further information please contact your iDM-partner.

According to the different types of house building and the different installation locations of the heat pumps different pipe lengths from the distributor of the sur-face collector to the heat pump are required.

The pressure loss in the brine pipes is increasing due to result of sinking temperature and rising portion of monopropylenglykol, at the mixture of the brine use the recommended concentration.

Installation plan

Notes

- Only antifreeze approved by iDM Energiesysteme GmbH are permitted for use.

- Brine circuit lines must be fi tted with steam diffusion-proofed insulation to protect against condensation and ice formation (e.g. Armafl ex).

- Brine circuit pump and the brine expansion tank are integrated in the TERRA SWM.

- When fi lling the brine circuit with antifreeze mixture, the expansion vessel must be fi lled (due do the volume reduction when cooling in service).

Design of the depth sensorIf the use of geothermal heat is in the closer selection, then obtain information about the soil conditions by a geological report. You fi nd out more details on requirements related, the expected soil layers, as well as notes about the maximum abstraction capacity.

The dimensioning of the depth sensors to achieve the necessary abstraction capacity must be occu-red by the drilling company or a geologist. Drilling may be performed only by a licensed company!

9.3. Ground water usage

DescriptionIn this system, groundwater is used as the heat sour-ce. When using groundwater, the water is pumped from an extraction reservoir, cooled in the safety heat exchanger and fed via an absorption reservoir back into the groundwater. In this process, ensure that the absorption reservoir is laid out in the groundwater fl ow direction after the extraction reservoir.

The heat exchange between the water and the brine medium in the intermediate circuit takes place in the safety heat exchanger (stainless steel plate heat ex-changer).

The heat exchange between the brine medium in theintermediate circuit and the refrigerant takes place in the evaporator.

The groundwater lines need to be created by the customer.

NotesWith an increased solid component (sand, mud), the relevant sedimentation tank should be fi tted to avoid blocking of the safety heat exchanger.

- Lay the incoming and outgoing lines to be frost proof, sloping towards the reservoir

- The lines in the building should be insulated against condensation

- From the extraction reservoir to the heat pump, a safety pipe with electrical cable for the reservoir pump is also required

- Make the reservoir lid light-proof and air-tight to prevent algae and sediment build-up

- A submersible pump is recommended for the reservoir pump

- After completion, the reservoir should be rinsed for approx. 48 hours.

Application range

Water inlet temperature: at least + 7 °C! (risk of frost!)

Ground water quality:

The following values must be observed:

- ph value: 6.5 - 9 - Chloride: < 100 mg/kg - Sulphate: < 50 mg/kg - Nitrate: < 100 mg/kg - Manganese: < 0.1 mg/kg* - Free carbon dioxide: < 20 mg/kg - Ammoniac: < 2 mg/kg - Iron: < 0.2 mg/kg* - Free Chloride: < 0.5 mg/kg - Electrical conductivity: 50 - 600 μS/cm - Oxygen: < 2 mg/kg*

* Exceeding these limit values means that the evaporator and the supply lines silt up, and the sink reservoir becomes clogged with iron.

To check the water temperature and the water quantityand quality, a test reservoir and a pump test is recom-mended for around 48 hours. The test should ideally be conducted at the end of February.

Installation plan

To be provided by the costumer: - Reservoir pump with the appropriate output - Motor protection switch for the reservoir pump - Water fi lter - Water fl ow meter with shut-off valves - Regulating valve - Thermometer, if required

To avoid corrosion and frost damage of the plate heat exchanger located in the heat pump, iDM- Energiesysteme instruct to install a safety heat exchanger for all ground water plants. Here the heat pump groundwater circuit is decoupled via a safety heat exchanger by a brine circuit. This means that any damage in the groundwater circuit or in the safety heat exchanger does not result in any additional damage to the heat pump.

At ground water plants with high pumping heads have to use corrogated tube hoses instead of fl e-xible connection hoses, because of the occuring low-pressure the fl exible connection hoses could be tightened.

Flushing and fi lling operationThe valves at the rinsing device and the expansion tank (fi g. above) have to be closed before fl ushing and fi lling operation. The expansion tank is not connected. To get no dirt in the tank, the expansion tank must be connected after the fl ushing process. After the fi lling of the brine circuit the valve of the expansion tank is opened. The pressure in the expansion tank before fi lling is 0.5 bar. The remaining brine mixture is fi lled up, so that the expansion tank is fi lled. The remaining air is blown off through the venting valve on the expansion tank. After fi lling, the pressure must be 1.0 bar in the expansion tank.

9.4. F i l l - and f lushing deviceFor the TERRA SWM a fi ll- and fl ushing device for the heat source is available as an accessory.

The set consists of the following parts: - TRIBLOC UK 32 DN 25 / 3 bar 50 kW - 2 pcs. Flushing-ball cocks 1“ - 1 pcs. ball cock with integrated fi lter 1“ - 1 pcs. ball cock 1“ for the return fl ow - Stair bolt M8 and clamps for the wall fastening

The fl ushing pump and a vessel for treatment of the brine mixture need to be accomplished on site. The heat source circuit has to be fl ushed before putting into service, to remove possible fouling. The fl ushing device has to be isolated on site with the connection pipes. To avoid dirt in the heat pump, it is necessary to close the delivered ball cock must be closed in case of servicing or repair works. The ball cock must be installed in the return fl ow of the heat pump. The ball cock is in the shipment of the fi ll- and fl ushing device. A fi lter ball valve is integrated in the fi ll- and fl ushing device. The fi lter ball valve must be cleaned regularly.
