Regulations
2.1 Water quality
Water quality in the heating system Heat pumps operate at lower temperatures than other heating systems which means that the thermal de-airing is not as effective and oxygen levels are never as low as with a system incorporating an electric/oil/ gas boiler. This means that the heating system will be more susceptible to corrosion when exposed to aggressive water.
Preventive actions are required if the heating systems require recurrent filling or where a heating water sample does not show clear water.
Preventive actions can be to supplement the heating system with a magnetite filter and a de-airing valve.
Actions when the heating system requires recurrent filling: Check that the volume of the expansion vessel is sufficient for the
heating system volume. Replace the expansion vessel. Check the heating system for leakages.
A system separation with the help of a heat exchanger may be required if the limits in table 2 can not be achieved.
The limits stated in table 2 are required to ensure the output data and operation of the heat pump throughout its entire life span.
Water quality Hardness Oxygen content Carbon dioxide, CO2 Chloride ions, CLSulphate, SO4 Conductivity pH
Table 2 Water quality
<3 °dH <1 mg/l <1 mg/l <250 mg/l <100 mg/l <350 S/cm 7,5 9
Additional water treatment to prevent lime-scale deposits
Poor quality of the heating water promotes the formation of sludge and lime-scale. This can lead to malfunctions and damage of the heat exchanger in the heat pump. According to the current guideline VDI 2035 "Avoidance of Damage in hot water heating systems" and depending on the degree of hardness of the filling water, the system volume and the total output of the system, water treatment may be required to avoid damage due to the formation of lime-scale.
NOTICE
Risk of damage to system or appliance! Debris from the system can damage the appliance and reduce efficiency. Follow the guidance of BS7593 for treatment of water in domestic
hot water heating systems1). Do not use anti-freeze/glycol products.
Suitable water treatment products (inhibitors/cleaners) can be obtained from the following manufacturers:

Preparing for installation
4 Preparing for installation
CAUTION
Risk of corrosion! Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient performance. Do not install the outdoor unit in areas where corrosive gases, such as
acid or alkaline gas, are produced. Do not install the product where it could be exposed to direct sea
wind (salty wind). Do not install the outdoor unit in the immediate vicinity of the sea, a
minimum distance to sea of 500 m is required. For France and Ireland the minimum required distance to sea is 1000 m.
4.1 Installation location Place the heat pump outdoors on a flat stable surface. When placing the heat pump, make sure it can be accessed at all
times in order to carry out maintenance work. If access is restricted, e.g. by placement on a roof, suitable measures must be taken to ensure that maintenance work still can be carried out without additional time expenditure or costly assembly aids. Bear in mind the sound propagation of the heat pump when placing it, particularly in view of avoiding of noise nuisance to neighbours. Whenever possible, do not place the heat pump in front of rooms sensitive to noise. Do not place the heat pump in a corner where it is flanked by walls on 3 sides. This can increase the noise level and increase the soiling of the evaporator.
Whenever possible, place the heat pump so that the front is not directly facing the wind, as strong winds may have a negative effect on the performance and function of the heat pump.
Position the heat pump so that no snow or water from the roof of the house drips or slides onto it. If this cannot be avoided, a protective roof for the heat pump must be installed.
If a protective roof is installed above the heat pump, bear in mind that it must be possible to lift the thermal insulation material of the heat pump up and off. With the models 5 OR-S9 OR-S, make sure there is a clearance of at
least 500 mm between the protective roof and the heat pump. With the models 13 OR-S17 OR-T, make sure there is a clearance of
at least 600 mm between the protective roof and the heat pump. If the protective roof can be removed, the minimum clearance above
the heat pump for all models is 400 mm.
Bear in mind that ice may form on the ground in front of the heat pump if it is equipped with a sound hood (accessory).

system
To safeguard the heat pump function and avoid an excessive number of start/stop cycles, incomplete defrosting and unnecessary alarms, it must be possible to store a sufficient amount of energy in the system. This energy is stored in the water volume of the heating system, and also in the components of the system (radiators) and concrete floor (underfloor heating system). As the requirements for different heat pump installations and heating systems vary considerably, a minimum water volume in litres is generally
Preparing for installation
not specified. Instead, the system volume is considered to be sufficient if certain conditions are met.
Underfloor heating system without buffer cylinder A room temperature-dependent control unit should be installed in the largest room (reference room) instead of room thermostats. Small floor areas can lead to the auxiliary heater being activated in the final phase of the defrosting process. · 6 m2 floor area required for heat pump 5 OR-S 9 OR-S. · 22 m2 floor area required for heat pump 13 OR-S 17 OR-T.
To ensure maximum energy savings and avoid auxiliary heater operation, the following configuration is recommended: · 30 m2 floor area for heat pump 5 OR-S 9 OR-S. · 100 m2 floor area for heat pump 13 OR-S 17 OR-T.
System with radiators without mixer and buffer cylinder If the system only contains a few radiators, the auxiliary heater may be activated in the final phase of the defrosting process. The radiator thermostats must be opened fully.
· 1 radiator with 500 W rating required for heat pump 5 OR-S 9 OR-S.
· 4 radiators each with roughly 500 W rating required for heat pump 13 OR-S 17 OR-T.
To ensure maximum energy savings and avoid auxiliary heater operation, the following configuration is recommended: · 4 radiators with 500 W rating for heat pump 5 OR-S 9 OR-S.
Heating system with underfloor heating system and radiators in separate heating circuits without buffer cylinders A room temperature-dependent control unit should be installed in the largest room (reference room) instead of room thermostats. Small floor areas or only a few radiators in the system can lead to the auxiliary heater being activated in the final phase of the defrosting process.
· 1 radiator with 500 W rating required for heat pump 5 OR-S 9 OR-S.
· 4 radiators each with roughly 500 W rating required for heat pump 13 OR-S 17 OR-T.
Although a minimum floor area is not required for the underfloor heating circuit, to avoid auxiliary heater operation and achieve optimum energy savings, additional heating thermostats or several valves of the underfloor heating system must be at least partially open.
Only heating circuits with mixer A buffer cylinder is essential in heating systems consisting only of heating circuits with mixer.
· Required volume for heat pump 5 OR-S 9 OR-S = 50 litres. · Required volume for heat pump 13 OR-S 17 OR-T = 100 litres.
Only fan convectors To prevent the auxiliary heater from being activated in the final phase of the defrosting process, a buffer storage tank with a capacity of 10 l is required.
Cooling mode If cooling mode is activated and run in combination with fan coils it is recommended to add a buffer cylinder 100 litres in the system for best performance and comfort.

unit.
To avoid leaks, only use material (pipes and connections) from the same PEX supplier.
To make installation easier and to avoid breaks in the insulation, use of insulated AluPEX pipes is recommended. The purpose of PEX and AluPEX pipes is to damp vibrations and reduce noise transmission to the heating system.
If materials other than PEX are used, the following prerequisites must be met:
Install a particle filter which is suitable for use outdoors in the return to the heat pump directly at the heat exchanger.
Insulate the particle filter and also the other connections. Establish the connection to the heat pump using a vibration-damping
hose which is suitable for use outdoors and also insulate it.

5.5.2 Water connecting pipe
NOTICE
Damage due to risk of frost! If the condensate freezes and cannot be routed away from the heat pump, the evaporator may be damaged. Always install pipe trace heating if ice is likely to form in the
condensate hose.
Remove condensate via a frost-free drain of the heat pump, possibly equipped with pipe trace heating. The drain must slope sufficiently to prevent water from accumulating in the pipe. The condensate can be routed to either a gravel bed, a stone box or into a rainwater gully. Route 32 mm plastic pipe from the condensate connection to a drain. Connection of pipe trace heating Chapter 7.1.
Installation
Connect return from the indoor unit at the heat transfer medium inlet of the heat pump ( [2], Fig. 18).
Tighten connections of the heat transfer medium pipes with a starting torque of 120 Nm. Direct the force downwards ( Fig. 18) to avoid lateral loading of the condenser. If the connection does not seal properly, the joint can be tightened with a starting torque of up to 150 Nm. If the connection is still not tight, this indicates that the gasket or connected pipe is damaged.

5.5.3 Connection of heat pump to the indoor unit
NOTICE
Material damage due to excessively high starting torque! If connections are tightened too tightly, the heat exchanger may be damaged. When installing the connection, the tightening torque should be no
more than 150 Nm.
Short pipe runs outdoors reduce heat losses. Use of pre-insulated pipes is recommended.
Use pipes in accordance with Chapter 5.5.1. Connect flow to the indoor unit at the heat transfer medium outlet of
the heat pump ( [1], Fig. 18).

5.5.4 Electrical connection
NOTICE
Malfunction due to faults! High-voltage lines (230/400 V) in the vicinity of communication lines can cause the heat pump to malfunction. Route sensor cable, EMS-BUS cable and shielded CAN-BUS cable
separately to power cables. Maintain a minimum distance of 100 mm. The BUS cable can be routed together with sensor cables.
The unit's electrical connection must be able to be disconnected safely. Install a separate safety switch that disconnects all power to the heat
pump if it is not supplied via the indoor unit. For a separate power supply, a safety switch is required for each supply.
Select the appropriate conductor cross-sections and cable types for the respective fuse protection and routing method.
Connect the heat pump according to the wiring diagram. No more users can be connected.
Install a separate residual current device according to applicable standards in each country. We recommend a type B residual current device.
When changing the PCB, note the colour coding.

Installation
CAN-BUS
NOTICE
The system will be damaged if the 12 V- and the CAN-BUS connections are incorrectly connected! The communication circuits are not designed for 12 V constant voltage. Check to ensure that the cables are connected to the contacts with
the corresponding markings on the modules.
The heat pump and indoor unit are connected by a communication line, CAN-BUS. A suitable cable for external cable installation is wire LIYCY (TP) 2x2x0,75, or equivalent. An alternative cable should have a cross section area of at least 0,75 mm2, and be a duplex cable, screened and approved for outside use. The screen should only be earthed to the chassis at one end (the indoor unit). Maximum cable length is 30 m. The connection is made with four wires, as the 12 V supply is also connected. On the circuit board there is a marking for 12 V and CAN-BUS connections. Switch Term is used to indicate the start and end of a CAN-BUS loop. The heat pump I/O module card should be terminated.
Fig. 19 Termination CAN-BUS
Connecting the heat pump
A CAN-BUS signal cable with the minimum dimensions 4 x 0.75 mm2 and a maximum length of 30 m must be routed between the heat pump and indoor unit.
Release belt (Velcro fastener). Remove the lock of the control device. Feed the connecting lead through the cable conduits. Use tension
springs if required. Connect cable as shown in the wiring diagram. Tighten all cable fixings if required. Reattach the cover of the control device. Reattach the belt.

Maintenance
6 Maintenance
DANGER Electrical shock! The heat pump contains current-carrying components and the heat pump capacitor must be discharged once the power supply has been disconnected. Isolate the system from the supply. Wait at least five minutes before carrying out electrical work.
DANGER Poisonous gas leakage! The refrigerant circuit contains substances that can be transformed into poisonous gas if they come into contact with air or open fire. Even in small concentrations, these gases can cause respiratory failure. Leave the area immediately if the refrigerant circuit is leaking and
ventilate thoroughly.
NOTICE
Malfunction due to damage! The electronic expansion valves are highly sensitive to impacts. Always protect the expansion valve from impacts and shock.
NOTICE
Deformation due to heat! If the temperature is too high, the insulation material (EPP) in the heat pump deforms. Remove as much insulation (EPP) as possible before carrying out
soldering work. When carrying out soldering work in the heat pump, protect the
insulation material with heat-resistant materials or a moist cloth.
Work on the refrigerant circuit must only be carried out by experts with the relevant qualifications.
Only use genuine spare parts! Refer to the spare parts list when ordering spare parts. Replace removed gaskets and O-rings with new ones. The tasks described below must be carried out during an inspection. Display activated alarm Check alarm log (controller manual). Function test Perform function check (indoor unit installation instructions). Install power cable Check the power cable for mechanical damage. Replace damaged cables.

9.3 Operating range of heat pump without auxiliary heater
The heat pump switches off at approx. 20 °C or +35 °C. The indoor unit or an external heat source then take over the heating and DHW heating. The heat pump restarts if the outdoor temperature exceeds roughly 17 °C or falls below +32 °C. In cooling mode the heat pump switches off at roughly +45 °C and restarts at roughly +42 °C.
