6.1 Safety during assembly

WARNING! Risk of injury due to improper assembly! Improper assembly leads to serious personal injuries and property damages. Therefore: - The assembly and startup must be performed by an

authorized heating and/or air conditioning profes-sional.

- Provide sufficient installation clearance before beginning with the work.

- Be careful with open components with sharp edges.

DANGER! Danger of life through electric current! Contact with live parts can lead to severest of inju-ries. Therefore: - Work on electrical systems may only be performed

by professional electricians. - Turn off electric power before beginning the work

activities, e.g. heating emergency switch, and secure against turning on again.

6.2 Requirements on the erec-tion location of the heat pump

Before doing the installation, make sure that the erection location meets the following requirements: - Operating temperature +5°C to +45°C - Dry, frost-proof, good air supply and ventilation - No heavy dust build-up - No high humidity - No air pollution through halogenated hydrocarbons (e.g. in

solvents, adhesives, spray cans) - No sulphur compounds - No vibrations and shocks

NOTE! In case of existing systems, a dirt filter must be installed on the heating side to protect the condenser.

Systems with above average temperature loads also require consultation with MHG Heiztechnik.

ThermiStar L .. SP 11.02.2012 6. Assembly

35/98

WARNING! Risk of life through fire! Easily flammable materials or liquids can catch fire. Therefore: - Do not use or store explosive or easily flammable

substances (i.e. fuel, paints, paper, wood) in the area where the device is installed.

- Do not dry or store laundry or clothes in the area where the device is installed.

- Do not operate device in explosive atmosphere un-der any circumstances.

The following aspects must be taken into consideration already during the planning of the system, in addition to proper dimensioning: - Future location of the heat pump under the aspect of sound

transmission through air and structure-borne sound. The acoustics in the erection rooms with reverberating walls can increase the operating sound significantly. Countermeasure: acoustic insulation on one of the opposite wall or ceiling surfaces.

- To reduce the structure-borne sound transmission, create a separate pedestal (e.g. heavy concrete) in mounted in floating fashion (e.g. on rubber).

- A pedestal is recommended for easier maintenance and care.

NOTE! MHG Heiztechnik recommends the installation of an oil sump-pump especially if the condenser is located shut off in a room for several hours (below 12 °C) and it becomes colder than the evaporator. This condition can occur especially in combination with special solar systems.

NOTE! Thorough planning with adequately dimensioned heat source is especially important for reasons of operational reliability and improved working output.

NOTE! If these comments are disregarded, the warranty becomes void in case of damages that can be traced to one of these causes.

Application limits

Heating water 20-55°C with refrigerant R 407 C Minimal outdoor temperature -15°C (continuous operation)

Installation clearances

Min. clearances according to Fig. 3 must be observed to allow all work activities (assembly, startup, maintenance) to be performed unhampered. - Observe the lateral clearance to the heat pump (min. 20 cm) to

allow access for service and inspection.


36/98

6.3 Assembly tools The assembly and maintenance of the heating system requires standard tools from the field of heating installations, cooling installa-tion technology, as well as water systems installations.

6.4 Assembly information

CAUTION! Environmental damage through substances hazardous to groundwater! Substances hazardous to groundwater, such as greases, oils, refrigerants, solvent-based cleaning agents and the like, can burden the ground or get into the sewage system. Therefore: - These substances must be collected, stored and

transported in suitable containers and be disposed off.

The regulations of the heating and plumbing trade (DVGW, DIN, etc.) and of electrotechnics (potential equalization, utility company connection conditions, DIN, VDE, etc.) must be followed in particular.

Transport

NOTE! The heat pump may only be transported standing and never horizontally.

The heat pump is delivered standing on a wooden pallet. It can be transported on the pallet to the installation site. The heat pump can also be transported by 2 persons with carrying straps or transport cart.

CAUTION! Device damage through improper handling! The copper pipes can be easily bent! Therefore: - Do not hold on to the insulated pipe (hot gas line)! - Apply force only to the base plate or the frame!


37/98

Refrigerant The safety datasheet concerning refrigerant R 410A is available for download at www.mhg.de\Download\Sicherheitsdatenblätter.

NOTE! In case of emergencies, ring the telephone number below: +44(0)208 762 83 22 [CareChem 24] (Europe)

WARNING! Danger of life through lack of oxygen! Vapors of the refrigerant R 410A are heavier than air and may cause suffocation by displacing oxygen. Therefore: - Exercise special caution when entering lower lying

closed rooms. - Work on the refrigerant circulation may only be

performed by persons certified according to Commission Regulation (EC) No 303/2008.

- Do not smoke when handling refrigerant as its products of decomposition in the lit cigarette act as an irritant and a poison!



NOTE! For operators of equipment containing 3kg or more of refrigerant the following duties of documentation apply: - Amount and type of refrigerant - Any amounts of refrigerant refills - Any amounts of refrigerant retrieved during startup,

maintenance or final disposal - Details identifying the company or technical per-

sonnel that carried out the installation, startup, or any maintenance work

- Dates and results of all inspections The recorded information must be presented to the relevant authorities and the commission upon re-quest.


38/98

Welding work NOTE! If any welding work is scheduled on the refrigerant line, a protective gas (i.e. nitrogen) will need to be passed through the pipe in order to prevent scale formation. Scale and other contamination can impair the proper operation of the device leading to disor-ders.

Assembly of the split evaporator



- The location of the evaporator must always be higher than the

heat pump unit (ensure proper gradient when installing cooling lines).

NOTE! Install the split evaporator in flow direction parallel to the property boundary (not towards the neighbouring plot) in order to reduce noise transmission to neigh-bouring properties.

NOTE! Ensure that no plants or objects are located in flow direction in order to guarantee efficient operation.

CAUTION! Device damage due to improper installation of cool-ing lines or improper positioning of the evaporator. Mechanical damage to the device can occur due to insufficient lubrication. Therefore: - Dimensioning and installation of cooling lines must

be carried out by technicians authorised by MHG. - The length of the cooling line may not exceed 15m

single distance. - The gradient of the cooling line from the split evap-

orator to the heating pump may not exceed 1.5 m. - The line dimensions are matched exactly to the capacity of the

heat pump (line length between heat pump and split evaporator up to max. 20 m). Altered line routing and clearances between heat pump and split evaporator must be agreed upon with MHG since the pipe dimensioning changes. Long line paths extend the thaw-ing process and are to be avoided.

- The lines are insulated with diffusion-proof material. The gaps of the insulation must be glued.


39/98

CAUTION! Environmental damage due to improper assembly of the refrigerant line! Refrigerant and compressor oil can leak! Therefore: - Only use tools recommended for work on cooling

devices: Bending pliers, pipe cutters, countersink and bordering tools

- Take note of bending radius to avoid bending or breaking of pipes.

- To avoid brittle or cracking pipes, do not bend the pipes repeatedly.

- In order to reduce loss of pressure and to ensure return of compressor oil, avoid unnecessary bending of the pipes.

- Use appropriate fastening and insulation during refrigerant line installation.

- Use only non-cutting tools (special pipe cutting tools) to shorten refrigerant lines.

CAUTION! Device damage Device damage through dirt and hu-midity! Dirt and humidity can enter the pipes when installing them. Therefore: - Make sure that no dirt or humidity enters the pipes

while installing them. - For underground installation the depth of the pipes

must be a min. of 25 cm (for areas exposed to traf-fic a min. of 50 cm).

- The installation of the pipelines must be carried out using a protective DN 100 pipe.

- The ends of the protective pipe must be sealed and waterproofed.

- The wall duct must be watertight. - Do not let clipping particles get into the refrigerant

line as these cause the destruction of the compres-sor.

NOTE! The heating pump contains refrigerant for a 15 m max. length cooling line. Any shortening or lengthening of the line may only be carried out by a certified technician. The refriger-ant dosage must be checked for line lengths exceed-ing 20 m, and be adjusted where required (approx. dosage values are available in chap. 5.3).

NOTE! The split evaporator contains a protective gas (nitro-gen) and must be evacuated simultaneously with the refrigerant lines.

NOTE! The technician must check the installation and mountings of the pipe, and establish a proper con-nection with the heating pump and the split evapora-tor.


40/98

NOTE! Ball valves must remain shut (delivery condition)!

43/98

Fig. 14: Pre-assemble the enclosure ass seen in the image prior

to installing the hydraulic and cooling lines.

CAUTION! Water damage through condensation or humidity in the air! Extremely low temperatures at the refrigerant lines lead to condensation or humidity in the air and can cause water damage. Therefore: - The heat source lines are lined with diffusion

resistant insulation which must not be damaged. - Any damage at the time of installation must be

sealed to ensure diffusion resistance. - Avoid contact of heat source lines carrying refrig-

erant with ambient air, by ensuring insulation is sealed without any gaps and absolutely diffusion resistant.

Connection of split evaporator with heat pump



- Connect the heat pump and the split evaporator with the

refrigerant lines.

CAUTION! Environmental damage due to improper assembly of the refrigerant line! Refrigerant and compressor oil can leak! Therefore: - Only use tools recommended for work on cooling

devices: Bending pliers, pipe cutters, countersink and bordering tools

- Take note of bending radius to avoid bending or breaking of pipes.

- To avoid brittle or cracking pipes, do not bend the pipes repeatedly.

- In order to reduce loss of pressure and to ensure return of compressor oil, avoid unnecessary bending of the pipes.

- Use appropriate fastening and insulation during refrigerant line installation.

- Use only non-cutting tools (special pipe cutting tools) to shorten refrigerant lines.

NOTE! The heating pump contains refrigerant for a 20 m max. length cooling line. Any shortening or lengthening of the line may only be carried out by a certified technician. The refriger-ant dosage must then be checked accordingly.

NOTE! The technician must check the installation and mountings of the pipe, and establish a proper con-nection with the heating pump and the split evapora-tor.

NOTE! Ball valves must remain shut (delivery condition)!

- Evacuate the suction, liquid and hot-gas lines. Connect the

devices to the Schrader valves for evacuation (see Fig. 10). - After the evacuation has been completed, open the ball valves to

allow the refrigerant to distribute. The system is operational after the electrical installation has been made.


47/98

6.5 Hydraulic connection

Requirements on the heating water To prevent corrosion damages in the heating system, heating water in potable quality must be used under the consideration of the re-quirements according to THE VDI GUIDELINE 2035 "Preventing damage in warm water heating systems" alternatively SWKI guide-lines 97-1 “Water composition for heating, steam, cooling and air-conditioning systems”.

NOTE! Do not use chemical additives.

CAUTION! Device damages through dirt or contamination! Partial clogging in the heat exchanger can lead to its destruction. Therefore: - For installations in older systems pre-filtration/silt

separation must be installed in order to protect the plate heat exchanger.

Do not use any chemical additives!

Fig. 17: Hydraulic connections

Legend for Fig. 17:

Abbr. Meaning 1 Flow 2 Return


48/98

Verify correct flow direction when connecting the hydraulic line. At the condenser, the in-flow is at the bottom (heating water return to heat pump). It is important with the hydraulic connection to observe the correct directions of flow. For the condenser the flow occurs at the bottom (return of heating water to heat pump). The temperature spread of 3-4 K at the heat source and 5-10 K at the heat drop must be maintained under normal operating conditions while observing the application limits. This spread is normally achieved when the volume flows specified in the technical data are observed.

6.6 Electrical connection

DANGER! Danger of life through electric current! Contact with live parts can lead to severest of inju-ries. Therefore: - Make sure that all electrical parts are without

current. - The applicable VDE and utility company regulations

as well as the respective regulations and guidelines of the country of destinations must be complied with.

- The electrical connections must be inspected by a responsible technician before establishing the connection with the line supply.

CAUTION! Interferences through electrical fields! Supply lines (230 V) may interfere with sensor lines (electrical low voltage). Therefore: - Sensor and supply lines may not be routed in the

same cable conduit.

7 Operation startup

7.1 Safety during startup

WARNING! Risk of injury due to improper operation! Improper operation leads to serious personal injuries or property damages. Therefore: - Installation and assembly must be performed by a

heating systems dealer. - Work on the refrigerant circulation may only be

performed by persons certified according to Com-mission Regulation (EC) No 303/2008.

- Perform all operating steps according to these instructions.

- Before starting with the work activities, make sure that electrical and hydraulic lines are shut off and secured against inadvertent opening.

- Use only suitable tools.

7.2 Inspection before startup Make sure of the following after proper assembly: - the electrical connection was performed correctly - the polarity of the line connection is correct - electrical voltage is applied - the heating system and the possibly available reservoir are

correctly filled and vented. - the correct installation of all required safety devices was made. - the water circulation is established to be in proper working order - all refrigerant lines and valves are sealed intact - refrigerant lines are covered with diffusion-resistant insulation,

without any gaps - all attachments, suspensions, etc. are fastened properly and have

been verified as to their proper height

7. Operation startup ThermiStar L .. SP 11.02.2012

60/98

7.3 Startup

NOTE! The customer / owner of the system must be present when starting up the system. A startup protocol must be established on site.

NOTE! For operators of equipment containing 3 kg or more of refrigerant the following duties of documentation apply: - Amount and type of refrigerant - Any amounts of refrigerant refills - Any amounts of refrigerant retrieved during startup,




CAUTION! Risk of injury due to refrigerant! Refrigerant leakage damages the environment 100- 24,000 times more than carbon dioxide (CO2). Therefore: - Hermetically sealed systems that contain 6 kg of re-

frigerant or more must not exceed a leakage rate of 1%.

CAUTION! Device damage through wrong direction of rotation of the condenser! Reverse running for several hours or day causes serious damages with loss of warranty. Therefore: - The use of the condenser requires that the correct

direction of rotation is determined and observed (right rotating field).

- When turning in the wrong direction, the condenser works much louder than usual and does not produce any output (compressed gas neck remains cold). A brief reverse run of a few minutes is not harmful.

Refer also to the "Startup order form".


61/98

Pump control - Circulating pump control - Unscrew pump stopper and turn pump shaft as illustrated below. - Screw pump stopper back in - Caution: Collect drops

Fig. 34: Remove pump stopper

Switching on the device

Once the proper installation verification and testing has been com-pleted, the power can be switched on. In order to do so, activate the installed power switch and automatic fuse.

Refrigerant dosage

The amount of refrigerant is established through the measurement and comparison of the refrigerant condensation temperature and heating pump flow temperature. The heat pump / compressor must be activated for min. of 10 min. and a flow temperature of approx. 50°C must be reached, before measurement or the results will not be reliable and the amount of refrigerant indicated will not be cor-rect. The difference between these two temperatures should be be-tween 0 and 3 K (condensation temperature - flow temperature).

Test for leak-tightness

Once operating, the refrigerant circuit must be rechecked for leak-age using a sensitive leak detection device/mittel.

8 Maintenance

8.1 Maintenance

NOTE! The respective regulations and guidelines of the country of destination must be complied with!

NOTE! Depending on the refrigerant dosage, the system op-erator must have the system inspected at least every 12 months. Amongst other things, this is a required for the sake of serviceability, performance and cost effectiveness. Work on the refrigerant circuit may only be per-formed by certified personnel.

The total system shall be inspected here for flawless function and any defects encountered shall be repaired without delay.

NOTE! Professional annual maintenance is stipulated according to the warranty conditions of MHG Heiztechnik.

DANGER! Danger of life through electric current! Contact with live parts can lead to severest of inju-ries. Therefore: - Work on electrical systems may only be performed

by professional electricians. - Turn off electric power before beginning the work

activities, e.g. heating emergency switch, and secure against turning on again.

- Set the operating switch on the boiler to "OFF".

NOTE! Inspect threaded joints for leaks during the annual maintenance. Replace defective or worn seals.

9 Troubleshooting

9.1 Troubleshooting

Faults and their removal If while the heat pump is running the heat discharge is suddenly interrupted (e.g. by a stopped heating circulation pump or closed valves), the high pressure safety limiter in the heat pump may be triggered (due to the thermal inertia of the system). The heat pump is thereby shut off and an automatic restart is prevented for safety reasons.

NOTE! Reduced service life of the high pressure safety limiter as well as the condenser due to excessive wear. Therefore: - Find out why the high pressure safety limiter was

triggered and remove the cause. Another possible reason for triggering this high pressure safety limiter may also be related to the local conditions of the heat pump's installation site which may necessitate the installation of an oil sump heater (strip heater on the condenser) or a "pump-down function".

Approach in case of malfunctions

If electrical errors (e.g. defective sensors) can be ruled out, begin with checking the circulation pump and valves of the heating system and heat source.

NOTE! If all errors can be ruled out on the external system, the cooling cycle of the heat pump must be checked by an authorized technician.

10 Warranty

10.1 Warranty

Limit of liability All specifications and information in these installation instructions were compiled under consideration of the applicable standards and regulations, the state of technology as well as our experience and insights of many years. MHG Heiztechnik does not assume any liability for damages due to: - Neglecting to follow the instructions for assembly, startup and

maintenance as well as the operating instructions - Use other than intended - Employment of untrained personnel - Unauthorized modifications - Technical changes - Use of unapproved spare parts - Inappropriate change of refrigerant dosage - Faulty production of refrigerant circulation The actual scope of delivery may deviate from the explanations and representations described here due to special designs, additional ordering options or latest technical changes.

Copyright protection

These instructions are copyright protected by MHG Heiztechnik. Copying in any type and format – even in excerpts – as well as the use and/or publication of the content or parts thereof are not permitted without written release authorization by MHG Heiztechnik. Infringements are liable to damage compensation. Additional claims are reserved. The instructions are to be treated confidentially. They are exclusively intended for persons working with the device. Leaving the instructions to a third party without written approval of the manufacturer is not permitted. The instructions shall remain with the heating device to allow them to be used at a later time, if needed. MHG is not liable for damages resulting from disregard of these instructions.

NOTE! The content, texts, drawings, illustrations and other presentations are protected by copyright and subject to commercial property rights. Any misuse is punishable by law.

10. Warranty ThermiStar L .. SP 11.02.2012

80/98

Warranty The ThermiStar heat pump by MHG renders its perfect function only when installed and started professionally. Warranty conditions of MHG can be taken from the warranty certificate.

Spart parts

NOTE! Use only original MHG spare parts in case of replacements: Some components have been designed and manufactured especially for MHG devices. Always specify the serial number when ordering spare parts.

CAUTION! Device damage through use of incorrect parts! Using parts not manufactured/supplied by MHG can cause material decomposition. Therefore: - Only parts specified by MHG must be installed in

the cooling unit.

Warranty claim for wearing parts

(See recommendation EHI European Heating Industry, information bulletin 14) The spare parts list also contains "spare parts" that must be replaced when the device is used as intended within the warranty period. The warranty periods have been extended by law makers, however, this does not preclude possible wear and tear from operation. It is known that a device may operate up to 8,760 hours a year when used as intended if this is a permanent operation system. According to customary commercial treatment, the costs incurred in these conditions are not covered by the warranty obligation or commitment of the manufacturer. The components listed in the spare parts list have been divided into the following categories: 1. Spart parts Spare parts are used for the repair of products

a) Parts are replaced that have not reached the expected service life although the device was operated as intended.

b) Furthermore, parts that are replaced due to improper operation or unintended use (e.g. wrong burner settings, water flow to low or too high, boiler scale through unsuitable filling water, use of incorrect refrigerant etc.).


81/98

2. Wearing parts Wearing parts are such parts which must be replaced

several times within the scope of service life while the product is used as intended (e.g. during maintenance).

3. Auxiliary materials Auxiliary materials are required with the repair and

maintenance of devices. Typical auxiliary materials are, for example, seals of all kinds,

hemp, lead oxide red or fuses. Auxiliary materials are not subject to any warranty claims, except

the necessary use in the context of replacing parts in the framework of an existing warranty claim.

Warranty certificate MHG provides warranty for compliance with explicitly promised properties, for non-defective construction and manufacturing as well as for flawless material in the manner that the parts which have become unusable as a result of such defects or where there usefulness was significantly compromised are delivers as new at their own costs and risk. MHG provides warranty for replaced parts to the same extent as for the original delivery item. The following warranty periods apply for the Thermistar heat pump:

- 2 years Material warranty for all electrical and other components as well as for heat pump function.

The ordering party can only assert warranty claims from MHG if the startup of the delivered item was performed by staff of MHG, companies trained by MHG or a qualified refrigeration company, the ordering party has observed the MHG regulations of the handling and maintenance of the delivered item, the prescribed inspections were done properly and no spare parts of third-party origin were installed. The complete and current delivery and warranty conditions can be taken from the MHG price list, on the back of the order confirmations, delivery notes and invoices as well as in the Internet at www.mhg.de. Per request, MHG can send the current general delivery and warranty conditions as printout via postal service. MHG Heiztechnik GmbH

10.2 Manufacturer Certificate / EU Design Conformity Declaration

Manufacturer Certificate Buchholz, 27.05.2009 MHG Heiztechnik GmbH hereby certifies the following for the heat pumps listed below: The heat pumps are equipped with different safety circuit devices for pressure limitation in the refrigerant cycle in compliance with DIN 32733. The low pressure guard switches to fault condition and thereby shuts off the condenser if already smallest amounts of refrigerant escape from the hermetically sealed refrigerant cycle of the heat pump through possible leaks. The refrigerant cycle is accommodated by the closed housing of the heat pump. The high pressure guard safety limit switch shuts off the condenser automatically if the pressure of the medium in the refrigerant cycle exceeds 28 bar. The refrigerants R407C or R134A and the cooling equipment machine oil (diester oil) are environmentally compatible. According to the EU safety data sheet, the refrigerant R407C consists of 23% difluoromethane (HFKW 32), 25% pentafluoroethane (HFKW 125) and 52% tetrafluoroethane (HFKW 125). According to the EG safety data sheet, the refrigerant R134A consists of 99.5% tetrafluoroethane (HFKW 125). The RVS 61 heat pump controller used by MHG in the system is equipped with sensors for the recording and control of the source outlet temperature and the heating flow temperature. If temperatures reach levels endangering the system, the heat pump is shut off automatically. MHG Heiztechnik GmbH
