9 Care/Cleaning

9.1Care

The heat pump is maintenance-free. To prevent malfunctions due to sediments in the heat exchangers, care must be taken that no im-purities can enter the heat source system and the heating installation. In the event that operating malfunctions due to contamination occur nevertheless, the system should be cleaned as described below.

9.2Cleaning og Heating Side

The ingress of oxygen into the heating water circuit, in particular if it contains steel components, may result in the formation of ox- idation products (rust). These can enter the heating system via valves, circulating pumps or plastic tubing. It is therefore impor- tant - in particular with respect to the piping of underfloor heating systems - that the installation be executed in a diffusion-proof manner.

10 Malfunctions / Troubleshooting

This heat pump is a quality product and designed for trouble- and maintenance-free operation. In the event that a malfunction oc- curs nevertheless, it will be indicated on the display of the heat pump controller. Simply consult the Malfunctions and Trouble- shooting table contained in the in-stallation and operating man- ual of the heat pump controller (manager).

If you cannot correct the malfunction yourself, please contact the after-sales service agent in charge.

ATTENTION!

All work on the heat pump may only be performed by an authorised an qualified after-sales service.

ATTENTION!

Disconnect all electrical circuits from the power supply before opening the enclosure.

ATTENTION!

To prevent the accumulation of deposits (e.g. rust) we recommend using a suitable corrosion protection system.

In the case of severe contamination leading to a reduction in the performance of the condenser in the heat pump, the system must be cleaned by a heating technician.

Based on current knowledge, we recommend cleaning with a 5% phosphoric acid solution or, in the case that cleaning needs to be performed more frequently, with a 5% formic acid solution.

In either case, the cleaning fluid should be at room temperature. It is recommended that the heat exchanger be cleaned in the di- rection opposite to the normal flow direction.

To prevent acidic cleaning agents from entering the circuit of the heating installation we recommend that the flushing device be fit- ted directly to the supply and return lines of the condenser of the heat pump.

Thereafter the system must be thoroughly flushed using appro- priate neutralising agents in order to prevent any damage caused by cleaning agent residues that may still be present in the sys- tem.

All acids must be used with great care, all relevant regulations of the employers' liability insurance associations must be adhered to.

If in doubt, contact the manufacturer of the chemicals!

9.3Cleaning of Heat Source Side

ATTENTION!

The supplied strainer must be fitted in the heat source inlet of the heat pump in order to protect the evaporator against the ingress of impurities.

The filter screen of the strainer should be cleaned one day after commissioning, thereafter every week. If no more contamination can be noticed any more, the strainer filter can be removed in order to reduce pressure losses.

11 Decommissioning / Disposal

Before removing the heat pump, disconnect the unit from the power source and close all valves.

Environment-relevant requirements regarding the recovery, re- cycling and disposal of service fuels and components in accord- ance with all relevant standards must be adhered to. Particular attention must hereby be paid to the proper disposal of refriger- ants and refrigeration oils.
