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.
