8 Start-up

8.1 General

To ensure that start-up 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).

Start-up should be carried out in heating operation.

8.2 Preparation

The following items need to be checked prior to start-up:

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

scribed in Chapter 7.

All valves that 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 manager’s oper-

ating instructions.

Ensure the condensate outflow functions properly.

8.3 Procedure

The heat pump is started up via the heat pump manager. Adjust-

ments should be made in compliance with the instructions.

At hot water temperatures under 7° C, start-up is not possible.

The water in the buffer tank must be heated to a minimum

of 18 °C with the second heat generator.

To ensure a problem-free start-up, the following procedure is to

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 "Start-up" 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 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 heat circuits are fully open and a return tempera-

ture of at least 18° C is maintained, the heat pump start-up

is complete.

ATTENTION!

Operating the heat pump at low system temperatures may cause the heat

pump to break down completely.

9 Cleaning / maintenance

9.1 Maintenance

To protect the paintwork, avoid leaning anything against the de-

vice or putting objects on the device. External heat pump parts

can be wiped with a damp cloth and 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

cannot be contaminated. In the event that operating malfunctions

due to contamination still occur, 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. They enter the heating system via the

valves, the circulating pumps and/or plastic pipes. It is therefore

essential - in particular with respect to the entire pipework - that

only diffusion-resistant materials are used.

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. We recommend equipping diffusion-open heating systems

with an electrophysical anti-corrosion system (e.g. ELYSATOR system).

Residue from lubricants and sealants may also contaminate the

heating water.

In the case 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 % phos-

phoric acid solution for cleaning purposes. However, if cleaning

needs to be performed more frequently, a 5 % formic acid solu-

tion should be used.

In either case, the cleaning fluid should be at room temperature.

We recommend flushing the heat exchanger in the direction op-

posite to the normal flow direction.

To prevent acidic cleaning agents from entering the heating sys-

tem circuit, we recommend connecting the flushing device di-

rectly 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 employ-

ers’ liability insurance associations must be adhered to.

The manufacturer's instructions regarding cleaning agent must

be complied with at all times.
