Care/Cleaning, Cleaning of Heating Side

9CARE/CLEANING

9.1 Care

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

CARE/CLEANING

CAUTION! Caution - Heating Technicians ! Depending on the filling water quality and quantity, in particular in the case of mixed installations and plastic pipes, mineral deposits (rust sludge, lime) may form, impairing the pro- per functioning of the heating installation. A reason for this is the water hardness and oxygen dissolved in the filling waters as well as additional oxygen from the air, which may penetrate via valves, fittings and plastic pipes (oxygen diffusion). As a preventive measure it is recommended that a physical water conditio- ner such as ELYSATOR be used.

9.2 Cleaning of Heating Side

The ingress of oxygen into the heating water circuit may result in the formation of oxidation products (rust). It is therefore important - in particular with respect to the piping of underfloor heating systems

-that the installation is executed in a diffusion-proof manner.

Also residues of lubricating and sealing agents may contaminate the heating water.

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

According to 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 direction 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 fitted directly to the supply and return lines of the condenser. To prevent any damage caused by cleaning agent residues that may be present in the system it is important that the system be thoroughly flushed using appropriate neutralising agents.

The 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!

9.3 Cleaning of Heat Source Side

CAUTION! The supplied strainer is to be install- ed in the heat source inlet of the heat pump in order to protect the evaporator against conta- mination.

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.
