8 Commissioning

8.1 General

To ensure that commissioning is performed correctly, it should

only be carried out by an after-sales service technician author-

ised by the manufacturer. This may be a condition for an addi-

tional warranty (see "Warranty service"). Commissioning should

be carried out in heating operation.

8.2 Preparation

The following items must be checked prior to commissioning:

All of the heat pump connections must be installed as de-

scribed in chapter 7.

The heat source system and the heating circuit must have

been filled and checked.

The dirt trap in the brine circuit (on the hydraulic 4-way re-

versing valve) must be installed.

All valves that could impair proper flow in the brine and

heating circuits must be open.

The heat pump manager must be adapted to the heating

system in accordance with the controller's operating in-

structions.

8.3 Procedure

The heat pump is commissioned via the heat pump manager.

CAUTION!

Commissioning must be performed in accordance with the

installation and operating instructions of the heat pump

manager.

9 Cleaning / maintenance

9.1 Maintenance

To prevent faults due to sediment in the heat exchangers, care

must be taken to ensure that no impurities can enter either the

heat source system or the heating system. In the event that op-

erating malfunctions due to contamination occur nevertheless,

the system should be cleaned as described below.

9.2 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 diffusion-

resistant installation is therefore essential, especially with re-

gard to the complete piping.

NOTE

ºººº

To avoid sediments (e.g. rust) in the heat pump condenser, it is

advisable to use a suitable corrosion protection system.We

recommend equipping open diffusion heating systems with

an electrophysical corrosion protection system (e.g.

ELYSATOR system).

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 tempera-

ture. We recommend flushing the heat exchanger in the direc-

tion opposite to the normal (heating operation) flow direction.

The position of the actuator on the 4-way mixer valve must be

observed here.

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 sys-

tem.

Acids must be used with care and the regulations of the em-

ployers liability insurance associations must be adhered to.

The instructions of the cleaning agent manufacturer must al-

ways be observed.

9.3 Cleaning the heat source

system

CAUTION!

The supplied dirt trap must be inserted in the heat source inlet

of the heat pump to protect the evaporator against the ingress

of impurities.

The filter sieve of the dirt trap should be cleaned one day after

start-up. Further checks must be set according to the level of

dirt. If no more signs of contamination are evident, the filter can

be removed to reduce pressure drops.
