Legal regulations and guidelines
This heat pump is designed for use in a domestic environment according to Article 1, Paragraph 2 k) of EU directive 2006/42/ EG (machinery directive) and is thus subject to the requirements of EU directive 2014/35/EU (low- voltage directive). It is thus also intended for use by non-professionals for heating shops, offices and other similar working environments, agricultural establishments and hotels, guesthouses and other residential buildings.
The construction and design of the heat pump complies with all relevant EU directives, DIN/VDE regulations (see CE declaration of conformity).
When connecting the heat pump to the power supply, the relevant VDE, EN and IEC standards are to be adhered to. Any further connection requirements stipulated by the mains supply network operator must also be observed.
When connecting the heating system, all applicable regulations must also be adhered to.
This unit can be used by children aged 8 and over and by persons with limited physical, sensory or mental aptitude or lack of experience and/or knowledge, providing they are supervised or have been instructed in the safe use of the unit and understand the associated potential dangers.
Children must not play with the device. Cleaning and user maintenance must not be carried out by children without supervision.

CAUTION
Work on the heat pump must only be performed by authorised and qualified after-sales service technicians!

CAUTION
When operating or maintaining a heat pump, the legal requirements of the country where the heat pump is operated apply. Depending on the refrigerant fill quantity, the heat pump must be inspected for leaks at regular intervals by a certified technician, and these inspections must be recorded.
More information can be found in the accompanying log book.

Energy-efficient use of the heat pump
By operating this heat pump, you are helping to protect the environment. A prerequisite for energy-efficient operation is the correct design of the heat source system and heating system. It is particularly important for the efficiency of a heat pump to keep the temperature difference between heating water and heat source as small as possible. For this reason, it is advisable to design the heat source and heating system very carefully. A temperature difference of approximately one Kelvin (1 °C) increases the power consumption by around 2.5 %. When designing the heating system, it should be borne in mind that special consumers such as domestic hot water preparation should also be taken into consideration and dimensioned for low temperatures. Underfloor heating systems (panel heating) are optimally suited for heat pump use on account of the low flow temperatures (30 °C to 40 °C).
It is important to ensure that the heat exchangers are not contaminated during operation, as this increases the temperature difference, which in turn reduces the COP.
When set correctly, the heat pump manager is also an essential factor in the energy-efficient use of the heat pump. Further information can be found in the heat pump manager operating instructions.

Intended use of the heat pump

Intended purpose
The air-to-water heat pump is to be used exclusively for the heating of heating water. It can be used in new or existing heating systems.
The heat pump is suitable for mono-energy and bivalent operation down to an external temperature of -22 °C. Proper defrosting of the evaporator must be guaranteed by maintaining a heating water return temperature of more than 22 °C during continuous operation.
The heat pump is not designed for the increased heat consumption required when a building is being dried out. For this reason, the additional heat consumption should be met using special devices provided by the customer. If a building is to be dried out in autumn or winter, we recommend installing an additional electric heating element (available as an accessory).
NOTE
The device is not suitable for operation with a frequency converter.

Operating principle
Surrounding air is drawn in by the fan and fed through the evaporator (heat exchanger). The evaporator cools the air, i.e. extracts heat from it. This extracted heat is then transferred to a working medium (refrigerant) in the evaporator.
The heat is brought to a higher temperature level by increasing its pressure with the aid of the electrically driven compressor. It is then transferred to the heating water via the liquefier (heat exchanger).
Electrical energy is used to raise the temperature of the heat from the environment to a higher level. Because the energy extracted from the air is transferred to the heating water, this type of device is referred to as an air-to-water heat pump. The main components of an air-to-water heat pump are the evaporator, fan and expansion valve, as well as the low-noise compressors, liquefier and the electrical control system. At low ambient temperatures, humidity accumulates on the evaporator in the form of frost, reducing the transfer of heat. Uneven accumulation during this process does not indicate a fault. The evaporator is defrosted automatically by the heat pump as required. Under certain atmospheric conditions, steam may be emitted from the air outlet.

Scope of supply

Basic device with switch box
The heat pump contains the components listed below.
The refrigeration circuit is “hermetically sealed” and contains the fluorinated refrigerant R407C included in the Kyoto protocol. Information on the GWP value and CO2 equivalent of the refrigerant can be found in the chapter Device information. The refrigerant is CFC-free, non-ozone depleting and non-combustible.

1. Evaporator
2. Fan
3. Switch box
4. Pressure controllers
5. Liquefier
6. Filter dryer
7. Compressor 1
8. compressor 2

Switch box
The switch box in the device can be folded out once the bottom front cover has been removed and the fixing screw has been loosened.
The switch box contains the supply connection terminals, power contactors, the soft starter units and the extended controller unit (refrigeration circuit control). The refrigeration circuit control monitors and controls all heat pump signals and communicates with the heat pump manager.
Communication and mains cables, which are to be routed apart from each other, are fed through the cable gland area on the baseplate into the switch box.
Heat pump manager
The heat pump manager included in the scope of supply must be used to operate the air-to-water heat pump. The heat pump manager is a convenient electronic regulation and control device. It controls and monitors the entire heating system based on the outdoor temperature, as well as domestic hot water preparation and safety systems. Sensors for the demand and outside temperature to be installed onsite, including mounting material, are included with the heat pump manager.
The enclosed operating instructions describe the function and use of the heat pump manager.

Transport

CAUTION
When transporting the heat pump, ensure that it is not tilted by more than 45° (in any direction). A pallet should be used to transport the heat pump to its final installation location. The basic device can be transported with a lift truck, hand truck or by means of 3/4″ pipes fed through the holes in the base plate or frame (max. pipe diameter in the evaporator- compressor frame area, 25 mm). In the frame area, the pipes must run parallel to the operator side (see figure)

The heat pump and the transport pallet are joined by four transit bolts. These must be removed.
Before using the transport holes in the frame, it is necessary to remove the two bottom side panel assemblies. Each covering panel is secured with two screws. Once the screws have been loosened, the covering panels can be tilted (top plates by approx. 20°, bottom plates by approx. 45°). The bottom facade plates can then be pulled out of the skirt panel, the top facade plates, which do not have to be removed for transport, can be hung out of the cover plate. Rehang the top panels by gently pushing them in an upwards direction.
NOTE
Be careful not to damage any components when inserting the pipes through the frame.
Any transport holes are to be covered at the installation location using the 8 black dust caps, which are included in the packaging of the device.
Once the heat pump has been set up in its intended location, the transport fastenings (2x M6 screws) must be removed from the compressor plate (the front or rear panel at the bottom must be removed for this)

CAUTION
Before commissioning, the transport fastening must be removed.

Installation

General
The device should always be installed on a permanently smooth, even and horizontal surface. The entire frame should be in direct contact with the ground in order to ensure an adequate soundproof seal, to prevent the water- bearing components from becoming too cold and to protect the inside of the device from small animals. If this is not the case, additional insulation measures may be necessary. To prevent small animals from entering the inside of the device, the connection hole in the base plate must be sealed, for example. Furthermore, the heat pump should be set up so that the air outlet direction of the fan is perpendicular to the main wind direction to allow unrestricted defrosting of the evaporator. The heat pump is designed for installation on even ground. In the case of different conditions (e.g.: installation on a platform or flat roof) or there is a greater risk of the heat pump tipping over (due to an exposed position or high wind exposure), additional protection against  tipping over must be provided. The responsibility for the heat pump installation lies with the specialist system construction company. During the installation, local requirements such as building regulations, static load of the building, and wind exposure must be accounted for.
It must be possible to carry out maintenance work without hindrance.
This is ensured when observing the distances to solid walls as shown in the figure.

NOTE
The heat pump is not intended for use over 2000 metres above sea level.
CAUTION
Do not restrict or block the area around the air intake or outlet.
CAUTION
Observe country-specific building regulations!
CAUTION
The physical impacts must be observed for installation close to walls. No windows or doors should be present in the area surrounding the air outlet of the fan.

CAUTION
In cases of installation close to a wall, there may be more sediment in the air inlet and outlet areas due to the air current.
The colder outside air outlet should discharge in such a way as to not increase the heat losses in heated neighbouring rooms.
CAUTION
Installation in a hollow or in an inner courtyard is not permitted because cooled air collects at ground level and is drawn in again by the heat pump during extended periods of operation.
Condensate pipe
Condensate that forms during operation must be drained off frost free. To ensure proper drainage, the heat pump must be mounted horizontally. The condensate pipe must have a minimum diameter of 50 mm and must be fed into a sewer in such a way that it is safe from frost. Do not discharge the condensate directly into clearing tanks or cess pits. The aggressive vapours and a condensate pipe laid in an area which is not frost-free can destroy the evaporator.

CAUTION
The frost line can vary according to the climatic region. The regulations of the countries in question must be observed.

Assembly

General
The following connections need to be established on the heat pump:

• Heating system flows and returns
• Condensate drain
• Communication line
• Control voltage line
• Supply voltage line

Connection on the heating side
The heating system connections on the heat pump are to be made inside the device. Refer to the device information for the connection sizes. The connection hoses are routed out of the device in a downwards direction. A spanner must be used to firmly grip the transitions when connecting the heat pump. Before connecting the heating water system to the heat pump, the heating system must be flushed to remove any impurities, residue from sealants, etc. Any accumulation of deposits in the liquefier may cause the heat pump to completely break down. For systems in which the heating water flow can be turned off using radiator and/or thermostat valves, an overflow valve must be installed by the customer in a heating bypass upstream from the heating pump. This ensures a minimum heating water flow rate through the heat pump and helps to avoid faults. Once the heat pump has been connected to the heating system, it must be filled, purged and pressure-tested. The installed dirt trap must be checked for soiling at regular intervals (approx. every 6 months) and cleaned if necessary.
The following points must be observed when filling the system:

• Untreated filling water and make-up water must be of drinking water quality (colourless, clear, free of sediments)
• Filling water and make-up water must be pre-filtered (max. pore size 5 μm). Scale formation in domestic hot water heating systems cannot be avoided, but in systems with flow temperatures below 60 °C, the problem can be disregarded. With high-temperature heat pumps and in particular with bivalent systems in the higher performance range (heat pump + boiler combination), flow temperatures of 60 °C and more can be achieved. The following standard values should therefore be adhered to with regard to the filling and make-up water according to VDI 2035, sheet 1:
  The total hardness values can be found in the table.

Total heat output in kW

| Total alkaline earths in mol/m³ and/or mmol/l| Specific system volume

(VDI 2035) in l/kW

---|---|---
< 20| ³ 20 < 50| ³ 50
Total hardness in °dH
< 50| £ 2,0| £ 16,8| £ 11,2|

< 0,111

50 – 200| £ 2,0| £ 11,2| £ 8,4
200 – 600| £ 1,5| £ 8,4| < 0,111

600| < 0,02| < 0,111

For systems with an above-average specific system volume of 50 l/kW, VDI 2035 recommends using fully demineralized water and a pH stabiliser to minimize the risk of corrosion in the heat pump and the heating system.
CAUTION
With fully demineralized water, it is important to ensure that the minimum permissible pH value of 7.5 (minimum permissible value for copper) is complied with. Failure to comply with this value can result in the heat pump being destroyed.
Minimum heating water flow rate
The minimum heating water flow rate through the heat pump must be assured in all operating states of the heating system. This can be accomplished, for example, by installing either a dual differential pressureless manifold or an overflow valve. The procedure for setting an overflow valve is described in the chapter “Start-up”. When the minimum heating water flow rate is undershot, the plate heat exchanger in the refrigeration circuit can freeze, which can lead to total loss of the heat pump. The nominal flow rate is specified depending on the max. flow temperature in the device information and must be taken into account during planning. With design temperatures below 30 °C in the flow, the design must be based on the max. volume flow with 5 K spread for A7/W35.
The specified nominal flow rate (See “Device information” on page 10.) must be assured in all operating states. An installed flow rate switch is used only for switching off the heat pump in the event of an unusual and abrupt drop in the heating water flow rate and not to monitor and safeguard the nominal flow rate.
Frost protection
Heat pump systems, which cannot be guaranteed to be frostfree, should be equipped with a drainage option (see Fig.). The frost protection function of the heat pump manager is active whenever the heat pump manager and the heat circulating pump are ready for operation. If the heat pump is taken out of service or in the event of a power failure, the system has to be drained, and if required, blown out, at three locations (see illustration). The heating circuit should be operated with a suitable antifreeze if heat pump systems are implemented in buildings where a power failure can not be detected (holiday home).

Electrical connection

3 lines/cables must be routed to the heat pump in total:

• A standard 5-core cable is used to connect the heat pump to the power supply.
  The cable must be provided on-site. The conductor cross section is selected in accordance with the power consumption of the heat pump (see attachment Device Information) and the applicable VDE (EN) and VNB regulations. An all-pole disconnecting device with a contact gap of at least 3 mm (e.g. utility blocking contactor or power contactor) must be installed in the heat pump power supply.
  A 3-pole circuit breaker with joint tripping of all outer conductors (trip current in accordance with device information) provides the short circuit protection taking into account the layout of the internal wiring.
  The relevant components in the heat pump contain an internal overload protection.
  When connecting, ensure that the incoming supply has a clockwise rotating field.
  Phase sequence: L1, L2, L3.
  CAUTION
  Ensure that there is a clockwise rotating field: With incorrect wiring the starting of the heat pump is prevented. A corresponding warning is indicated on the display of the heat pump manager (adjust wiring).

• The control voltage is supplied via the heat pump manager.
  A 3-pole line must be laid for this in accordance with the electrical documentation. Further information on the wiring of the heat pump manager is available in the heat pump manager operating instructions.

• A shielded communication line (not included in the scope of supply) connects the heat pump manager with the refrigeration circuit controller installed in the heat pump.  More detailed instructions can be found in the heat pump manager operating instructions and in the electrical documentation.
  NOTE
  The communication cable is necessary for the function of airto- water heat pumps in outdoor installation. It must be shielded and laid separately from the mains cable.

Demand sensor connection
The demand sensor R2.2 (NTC 10) is included with the heat pump manager. It must be installed depending on the hydraulics used (see attachment chapter 3 on page V). If no request sensor is connected, regulation of the 2nd heat generator will not be possible in the event that communication with the heat pump manager is disrupted.
NOTE
The return sensor R2 installed in the heat pump is active when the compressor is running and must not be disconnected.

Commissioning

General
To ensure that commissioning is performed correctly, it should only be carried out by an after-sales service technician authorised by the manufacturer. These measures can also include an additional warranty under certain conditions (see Warranty).
Preparation
The following items must be checked prior to commissioning:

• All of the heat pump connections must be installed as described in chapter 6.
• All valves which could impair the proper flow of the heating water in the heating circuit must be open.
• The air intake and air outlet paths must be clear.
• The fan must turn in the direction indicated by the arrow.
• The settings of the heat pump manager must be adapted to the heating system in accordance with the latter’s operating instructions.
• Ensure that the condensate drain functions properly.

Procedure
The heat pump is commissioned via the heat pump manager.
Settings should be made in compliance with the HPM’s instructions. At heating water temperatures below 7 °C, commissioning is not possible. The water in the buffer tank must be heated to a minimum of 22 °C with the second heat generator.
To ensure problem-free commissioning, the following procedure must be implemented:

1. Close all consumer circuits.
2. Ensure that the heat pump has the correct water flow.
3. Use the manager to select the automatic operating mode.
4. In the special functions menu, start the “Commissioning” program.
5. Wait until a return temperature of at least 25 °C has been reached.
6. Now slowly reopen the heating circuit valves in succession so that the heating water flow rate is constantly raised by slightly opening the respective heating circuit. The heating water temperature in the buffer tank must not be allowed to drop below 20 °C during this process. This ensures that the heat pump can be defrosted at any time.
7. When all heating circuits are fully open and a return temperature of at least 22 °C is maintained, the commissioning is complete.

CAUTION
Operating the heat pump at low system temperatures may cause the heat pump to break down completely.

Cleaning / maintenance

Maintenance
To protect the paintwork, avoid leaning anything against the device or putting objects on the device. External heat pump parts can be wiped with a damp cloth and commercially available domestic cleaner.
NOTE
Never use cleaning agents containing sand, soda, acid or chloride, as these can damage the surfaces.
To prevent faults due to sediment in the heat exchanger of the heat pump, ensure that the heat exchanger in the heating system can not be contaminated. Should operating malfunctions due to contamination still occur, however, the system should be cleaned as described below.
Cleaning the heating system
The ingress of oxygen into the heating water circuit may result in the formation of oxidation products (rust), particularly if steel components are used. These enter the heating system via the valves, the circulating pumps and/or plastic pipes. A diffusionresistant installation is therefore essential, especially with regard to the piping of underfloor heating systems.
NOTE
We recommend the installation of a suitable corrosion protection system to prevent the formation of deposits (e.g. rust) in the condenser of the heat pump.
Residue from lubricants and sealants may also contaminate the heating water.
In the event of severe contamination leading to a reduction in the performance of the liquefier in the heat pump, the system must be cleaned by a heating technician. Based on current information, we recommend using a 5% phosphoric acid solution for cleaning purposes. However, if cleaning needs to be performed more frequently, a 5% formic acid solution should be used.
In both cases, the cleaning fluid should be at room temperature. We recommend flushing the heat exchanger in the direction opposite to the normal flow direction. To prevent acidic cleaning agents from entering the heating system circuit, we recommend connecting the flushing device directly to the flow and return of the liquefier of the heat pump. It is then important that the system be thoroughly flushed using appropriate neutralising agents to prevent any damage from being caused by cleaning agent residue remaining in the system. Acids must be used with care and the regulations of the employers liability insurance associations must be adhered to.
The instructions of the cleaning agent manufacturer must always be observed.
Cleaning the air system
The evaporator, fan and condensate drain should be cleaned of contamination (leaves, twigs, etc.) before each new heating period. The top covering panels of the heat pump see cap. 4 must be removed for this. The bottom left covering panel may also have to be removed for cleaning the condensate drain or the condensate pipe.
CAUTION
Before opening the device, ensure that all circuits are powered down. Remove and re-hang the side panel assemblies as described in chapter 4. To prevent the evaporator and the condensate tray from being damaged, do not use hard or sharp objects when cleaning. Under extreme weather conditions (e.g. snow drifts), ice may form on the air intake and air outlet grids. If this happens, the ice must be removed from the vicinity of the air intake and air outlet grids to ensure that the minimum air flow is maintained.

Faults / troubleshooting

This heat pump is a quality product and is designed for troublefree operation. Should a fault occur, however, it will be indicated on the heat pump manager display. In this case, consult the “Faults and troubleshooting” page in the operating instructions of the heat pump manager. If you cannot correct the fault yourself, please contact your after-sales service technician.
CAUTION
Before opening the device, ensure that all circuits are powered down. After disconnecting the power supply, always wait for at least 5 minutes to allow stored electric charges to dissipate.
CAUTION
Any work on the heat pump may only be performed by authorised and qualified after-sales service technicians.

Decommissioning / disposal

Before removing the heat pump, disconnect it from the power source and close all valves. The heat pump must be dismantled by trained personnel. Observe all environmental requirements regarding the recovery, recycling and disposal of materials and components in accordance with all applicable standards. Particular attention should be paid to the proper disposal of refrigerants and refrigerant oils.
