Operating principle of heat pumps
Heat pumps operate on the same principle as a refrigerator: same technology, only with reversed benefits. The refrigerator extracts heat from foods, which is released into the room through fins on the back.
The heat pump extracts heat from our environment: air, earth or water. The extracted heat is conditioned in the unit and supplied to the heating water. Even when it is extremely cold outside, the heat pump draws enough heat to heat a house.
Example: drawing of a brine/water heat pump with underfloor heating:
4/4 = usable energyapprox. 3/4 = environmental energyapprox. 1⁄4 = external
electrical energy
Area of utilisationTaking into consideration the ambient conditions, limits of application and the applicable regulations, every heat pump can be utilised in new or existing heating systems.

Care of the unitThe outer surfaces of the unit can be cleaned with a damp cloth and household cleaning products.Do not use cleaning or care products that contain abrasives, acids and/or chlorine. Such products would destroy the surfaces and could also damage the technical components of the unit.
Maintenance of the unitThe cooling circuit of the heat pump requires no regu-lar maintenance.
According to EU regulation (EC) 517/2014, leak inspections and maintenance of a log book are required by law for certain heat pumps!
Log book for heat pumps, Section “Information on use of the log book”.
The components of the heating circuit and the heat source (valves, expansion vessels, circulating pumps, filters, dirt traps) should be inspected and cleaned as necessary - however, at least once a year - by qualified personnel (heating or cooling system fitters).The intake and blow-out openings must be inspected for dirt at regular intervals (depending on the installation location) and cleaned, if necessary.
ATTENTION Regularly check to ensure that the condensate
can drain out of the unit unobstructed. To do this, regularly check the condensate tray in the unit and the condensate drain for dirt / blo-ckages and if necessary clean.

INSTALLATION
PREPARING THE INSTALLATION, TOGETHER WITH THE WALL PENETRATION
To connect the outdoor unit with the indoor part (hydraulic module), an opening must be provided for the wall penetration (accessory) or a hole must be made to enable the KG pipe Ø125 mm (= accessory Wall penetration) to be installed. If the wall penetration is not yet available, it is possible to work in advance using a standard KG pipe, 1m long DN 125.
NOTE. Always keep to the installation plan for the re-
spective model. Observe minimum spacings and protection areas.
Installation plan and dimensional drawings and protection areas for the respective model.
CAUTION. In the air outlet area the air temperature
is ca. 5 K below the ambient temperature. Under certain climatic conditions, therefore, an ice layer can form in the air outlet area. Install the heat pump so that the air blower does not blow in the direction of footpaths.
CAUTION. Several people are required to install the
unit.
NOTE. The ground surface in the air outlet area of the
heat pump must be permeable to water.
NOTE. Always ensure you keep to the specified distance
from the wall, from wall openings, windows, light wells and similar.
See “Dimensional drawings and protection areas”.
NOTE. If the wall penetration is not used, the LIN bus
cable must be laid through a separate conduit, separated from the other cables.
The two other cables must also be laid on site using reserve conduits.
NOTE. Always ensure minimum wall area is available. Always keep to the installation plan. Note and
keep to minimum spacings.
INSTALLATION WITH WALL BRACKET
See “Installation instructions wall bracket”..
See ”Wall penetration installation instructions”.
See “Installation plans/minimum spacings/drilling pattern”.
The wall bracket is only suitable for solid. load-bearing walls. In the case of wooden stud walls with panelling the floor-mounted bracket should be used to avoid possible structurally-borne sound transfer to the interior rooms
INSTALLATION ON FLOOR BRACKET
It is possible to install the unit near a wall or in an open space. The heat pump should ideally be installed in a wind-protected position. If this is not possible it is advisable to install it transversely to the main wind direction or air routing with the main wind direction.
Place the unit on a solid, level and load-bearing foundation. The foundation must not be connected to the building. Make sure that the foundation is designed for the weight of the heat pump.
See “Installation instructions floor bracket”.
See “Wall penetration installation instructions”.
See “Installation plans/minimum spacings/view of foundation”.
NOTE. If installing with wall penetration, ensure the
correct distance from the wall is maintained.
CONDENSATE DRAIN
The condensate from the air must be discharged frost-free through a plastic condensate pipe with a minimum diameter of 40 mm. If subsoils are permeable to water, it is sufficient to lay the condensate pipe vertically at least 90 cm into the ground.

Domestic hot water tankIf the heat pump is to be used for domestic water heating, you must integrate special domestic hot water tanks in the heat pump system. Choose a storage volume so that the required quantity of hot water is available even during a power cut.
NOTE. The heat exchanger surface of the domestic hot
water tank must be dimensioned so that the he-ating capacity of the heat pump is transferred with minimum spread.
We offer a variety of domestic hot water tanks for you to choose from. They are optimised for use with your heat pump.
NOTE. Integrate the hot-water tank in the heat pump
system according to the hydraulic diagram for your system.

DAMAGE THAT CAN OCCUR IN CASE OF NON-COMPLIANCE
- Malfunctions and the failure of components (e.g. pumps, valves)
- Internal and external leaks (e.g. from heat exchangers)
- Cross-section reduction and blockaging of components (e.g. heat exchanger, pipes, pumps)
- Material fatigue
- Gas bubbles and gas cushion formation (cavitation)
- Negative effect on heat transfer (formation of coatings, deposits) and associated noises (e.g. boiling noises, flow noises)
LIMESCALE – THE ENERGY KILLER
Filling with untreated drinking water inevitably leads to the precipitation of all calcium as scale. The consequence: limescale deposits form on the heat transfer surfaces of the heating. The efficiency falls and the energy costs rise. A rule of thumb is that 1 millimetre of limescale deposit causes an energy loss of 10%. In extreme cases it can even cause damage to the heat exchangers.
WATER SOFTENING TO VDI 2035 – PART I
If the water is softened before the heating is filled, in accordance with the VDI 2035 guidelines, no scale can form. This effectively and permanently prevents limescale deposits and the resulting negative effects on the entire heating system.
CORROSION – AN UNDERESTIMATED PROBLEM
VDI 2035, Part II, deals with the problem of corrosion. Softening the heating water can prove to be insufficient. The pH value can significantly exceed the limit of 10. pH values higher than 11 can set in, which even damage rubber seals. The VDI 2035, Part 1 guidelines are fulfilled, however, VDI 2035, Part 2 suggests a pH value between 8.2 and maximum 10.
If aluminium materials are used, which is the case in many modern heating systems, a pH value of 8.5 must not be exceeded, because otherwise there is a threat of corrosion – and aluminium is attacked without the presence of oxygen. Therefore, apart from softening the heating fill and additional water, the heating water should also be appropriately conditioned. This is the only way to comply with the VDI 2035 requirements and the recommendations and installation instructions of the heat pump manufacturer.
Rinsing, filling and bleeding the system
See “Operating instructions, hydraulic module or hydraulic module Dual”.
CAUTION. The system must be absolutely free from air be-
fore commissioning.
WATER QUALITY OF THE FILL AND ADDITIONAL WATER IN HOT WATER HEATING SYSTEMSACCORDING TO VDI 2035 PART I AND II
Use of modern, energy-efficient heat pump systems is becoming increasingly widespread. Their ingenious technology enables these systems to achieve very good efficiencies. The decreasing space available for heat generators has led to the development of compact units with increasingly smaller cross-sections and high capacities. This means the complexity of the systems and the material diversity are also increasing, which plays an important role especially in their corrosion behaviour. The heating water not only affects the efficiency of the system, but also the life of the heat generator and the heating components of a system.The guide values of VDI 2035 Part I and Part II must therefore be complied with as minimum requirements for proper operation of the systems. Our practical experience has shown that the safest and most trouble-free running of the systems is achieved with so-called low-salt operation.VDI 2035 Part I gives important information and recommendations regarding scaling and its prevention in heating and domestic hot water heating systems.VDI 2035 Part II primarily deals with the requirements for reducing heating water corrosion in hot water heating systems.
PRINCIPLES OF PART I AND PART II
The occurrence of scaling and corrosion damage in hot water heating systems is low, if
- proper planning and commissioning is carried out
- the system is closed in corrosion terms
- adequately dimensioned pressurising is integrated
- the guide values for the heating water are complied with
- and regular servicing and maintenance are carried out.
A system log should be kept, in which the relevant planning data is entered (VDI 2035).

Insulating the hydraulic connections
Insulate the piping of the heating circuit and the condensate pipe in the outdoor area so that they are frost-proof, vapour-diffusion tight and UV resistant.
NOTE. Insulate in accordance with applicable local stan-
dards and guidelines.
Check all hydraulic connections for leaks. Perform leak test…
Insulate all connections and pipes of the heat circuit (RX-variants vapour diffusion insulated).
Part 2 of VDI 2035 also points out the reduction in total salt content (conductivity). The risk of corrosion is far lower if deionised water is used than is the case if the system is operated with salty, i.e. softened water.
Even if the water has been softened beforehand, it contains dissolved, corrosion-promoting salts, which act as electrolytes due to the use of different materials in the heating system and therefore accelerate corrosion processes. This can ultimately result in pitting.
Contamination and deposits in the heating circuit can cause malfunctions
RINSE, FILL AND BLEED THE HEATING CIRCUIT AND HOT WATER BUFFER TANK
To bleed the hot water tank, the heating circuit and hot water circuit must be rinsed simultaneously.
ON THE SAFE SIDE WITH LOW-SALT OPERATION
The problems listed above do not occur at all with low-salt operation, as neither corrosive salts such as sulphates, chlorides and nitrates nor alkalising sodium hydrogen carbonate are in the heating water. The corrosive properties of deionised water are very low and in addition, fur cannot form in the boiler. This is the ideal approach for closed heating circuits, in particular, because low oxygen input into the heating circuit can also be tolerated.
In general, when the system is filled with deionised water, the pH value sets itself within the ideal range due to “self-alkalinisation”. If necessary, a pH value of 8.2 can be very easily alkalised by adding chemicals. In this way, optimum protection of the entire heating system is achieved.
MONITORING
Analytical recording and monitoring of the relevant water values and the added active conditioning substances is of decisive importance. Therefore, they should be monitored regularly using appropriate water test equipment.
Fill and bleed the heating circuit…
In addition, open the bleeding valve on the condenser of the heat pump. Bleed condenser…

WITHDRAWAL FROM SERVICE
It is particularly important that the technician responsible for the withdrawal from service work is familiar with all details of the disposal equipment. We recommend that all refrigerant be recovered.
Before disposing of the drained fluids, take samples of the oil and refrigerant, if the refrigerant is to be treated for reuse.
NOTE. It is important for electricity to be available
where the work is to be carried out.
a) Familiarise yourself with the units and their function.
b) Disconnect the unit to be disposed of from the power supply.
c) Before starting the disposal procedure, ensure that:
- mechanical aids required for the transport of refrigerant cylinders are available if necessary;
- personal protective equipment is available and is properly used;
- the extraction process is continuously monitored by a competent person;
- the disposal station and refrigerant cylinders conform to the relevant guidelines and directives.
d) If possible, carry out a pump-down cycle.
e) If it is not possible to establish a vacuum, extract through a collection pipe, so that refrigerant can be removed from all parts of the system.
f) Ensure that the refrigerant cylinder is on the scales before starting the extraction.
g) Switch on the disposal equipment and continue according to the manufacturer’s instructions.
h) Ensure that recycling cylinders are not overfilled (never more than 80 % of the liquid fill quantity).
i) Never exceed the allowable operating pressure of the recycling cylinder, not even for a short time.
j) When the recycling cylinders are properly filled and the process has been completed, ensure that the cylinders and units are immediately removed from the system and all shut-off valves are closed.
k) Recovered refrigerant cannot be used in other systems until it has been cleaned and examined.
MARKINGS
Units must be appropriately marked or labelled so that it is clear to all that they have been withdrawn from service and the refrigerant has been removed. This marking must be dated and signed. Ensure that information regarding flammable refrigerant is attached to the units.
RECOVERY/RECYCLING
If refrigerant is extracted for repair or withdrawal from service purposes, ensure that this is done safely. If coolant is transferred into cylinders, ensure that only suitable refrigerant cylinders are used. Ensure that a sufficient number of refrigerant cylinders are available for the quantity in the system. All refrigerant cylinders used must be intended for the refrigerant to be extracted and marked accordingly (i.e. special recycling cylinders for the recovery and recycling of refrigerant). The refrigerant cylinders must have a safety valve and securely attached shut-off valves and be in a good condition. Empty recycling cylinders are evacuated and should be cooled before the extraction process, if possible. The disposal equipment must be in a good condition and suitable for the recovery of flammable refrigerants. Instructions on the individual recovery procedure steps must be enclosed with the equipment. In addition, calibrated scales must be available and must also be in good condition. Hoses must be equipped with leak-free couplings and be in good condition. Before the disposal equipment is used, check that it is in good condition, that it has been serviced at the specified intervals and that the corresponding electrical devices are sealed to prevent ignition in case of refrigerant leaks. In case of doubt, contact the manufacturer for advice. The recovered refrigerant must be returned to the supplier in a proper recycling cylinder. Do not mix refrigerants in refrigerant cylinders. If compressors or compressor oil is to be disposed of, ensure that they are evacuated with an adequate vacuum to ensure that there is no longer any flammable refrigerant in the oil. Before the compressor is returned to the manufacturer it must be evacuated. This process may only be accelerated by means of electrical heating of the compressor housing. When oil is drained from a system, it must be done with appropriate caution.

Installation of heat pump protection area
Important: The heat pump may only be installed outdoors! The unit must be positioned so that in case of a leak the refrigerant cannot
get into the building or put people at risk in any other way.
In the protection area (see figure), which is located between the top edge of the unit and the floor, there must be no ignition sources, windows, doors, ventilation openings, light wells and similar. The protection area may not extend onto adjacent properties or public traffic areas. The wall penetration through the building envelope must be made gas-tight.

Wichtig: Beim direkten Einleiten des Kondenswassers in die Erde (Abbildung 1a), muss das Kondensatablaufrohr (3) zwischen Boden und Wärmepumpe isoliert werden.
Wichtig: Bei direktem Einleiten des Kondenswassers in eine Abwasser- oder Regenwasserleitung muss ein Syphon gesetzt werden (Abbildung 1b). Es muss ein oberhalb des Bodenreichs gedämmtes und senkrecht verlegtes Kunststoffrohr verwendet werden. Weiterhin dürfen im Abflussrohr keine Rückschlagklappen oder ähnliches installiert sein. Das Kondensatablaufrohr muss so angeschlossen werden, dass das Kondensat frei in die Hauptleitung einfließen kann. Wird das Kondensat in Drainagen oder in die Kanalisation abgeleitet, ist auf eine Verlegung mit einem Gefälle zu achten.
In allen Fällen (Abbildung 1a und Abbildung 1b) muss gewährleistet sein,dass das Kondenswasser frostfrei abgeführt wird.

Installation instructions for connecting the condensate pipe outside the building
KS Gravel layer for absorbing up to 50l condensation water per day
as buffer zone for percolating.
3 Condensate drain pipe DN 40
Important: If the condensation water is discharged directly into the ground (figure 1a)
the condensate drain pipe (3) must be insulated between the ground and the heat pump.
Important: If the condensation water is discharged directly into a wastewater or
rainwater pipe a syphon must be used (figure 1b).
A plastic pipe, laid vertically and insulated above the ground, must be
used. Further, do not install any non-return valves or similar in the drain pipe.
The condensate drain pipe must be connected so that
the condensate can flow freely into the main pipe. If the condensate is
discharged into filter drains or the sewers, ensure the pipes are laid with a gradient.
In all cases (figure 1a and figure 1b) ensure that
the condensation water is discharged in a frost-free zone.

Wichtig: Beim Anschluss der Kondensatleitung innerhalb eines Gebäudes muss ein Syphon eingebaut werden, der mit dem Abflussrohr gasdicht abschließt (siehe Abbildung 2a). An der Kondensatabflussleitung der Wärmepumpe dürfen keine zusätzlichen Abflussleitungen angeschlossen werden. Die Abflussleitung in Richtung Kanalisation muss frei sein. D.h. nach der Anschlussleitung der Wärmepumpe darf weder eine Rückschlagklappe noch ein Syphon eingebaut werden.
In allen Fällen (Abbildung 2a) muss gewährleistet sein, dass das Kondenswasser frostfrei abgeführt wird.

Installation instructions for connecting the condensate pipe inside the building
.
Important: When connecting the condensate pipe inside the building, a syphon
must be installed, which is connected gas-tight to the drain pipe (see figure 2a).
Do not connect any additional drain pipes to the condensate drain pipe of the heat pump.
The drain pipe must be free in the direction of the sewer.
I.e. ensure that downstream of the heat pump connection pipe there are no
non-return valves or syphons.
In all cases (figure 2a) it must be ensured that the condensation water is discharged in a frost-free zone
