inspection contract.

Indoor unit

4.1.1

Checking the operating pressure

The pressure should be checked 1-2 times per year.
▶ Check the pressure at the pressure gauge.
▶ If the pressure is less than 0.5 bar, increase the pressure slowly to
max. 2 bar by filling with water via the fill valve.
▶ If you have any questions about the procedure, consult the installer of
the system.
4.1.2

Moisture in cooling mode

NOTICE
If moisture frequently forms near the indoor unit or the fan convectors in
cooling mode, this could mean that the condensation insulation is
defective.
▶ If moisture forms in the vicinity of components of the heating system,
switch the heat pump off and consult the system installer.
4.1.3

Checking the safety valves

The safety valves should be checked 1-2 times each a year.
Water is expelled from the safety valve during heat-up. Never close the
safety valve.
▶ The safety valve should only let water out if the maximum pressure is
exceeded. Contact the installer if water is coming from the safety
valve at pressures below 2 bar.
▶ The drainage hose from the safety valve shall be discharged into the
sewage / floor well.
