Checking the compressor casing temperature
1. Release the front top panel.
2. Undo the screws and the crossbar.
3. Start the heat pump and let it run
for at least 10 min (see page 116,
point 1 and 2).
4. Measure the temperature of the
compressor casing exterior while it
is in operation.
Ice must not form on the outside of
the compressor, and the housing
must not become warmer than 60
°C (otherwise consult the Technical
Service department at Viessmann).
5. Lift the crossbar and set the front
part of the thermal insulation onto
the heat pump.
6. Secure the crossbar.
7.
Danger
The absence of component
earthing can transfer dan-
gerous body currents,
should an electrical fault
occur.
Always connect the earth
strap to the crossbar and the
top panel.
Fit the front top panel.
Cleaning the interior of the DHW cylinder
Danger
An uncontrolled exit of DHW or heat transfer medium can lead to scald-
ing and building damage.
Only open the DHW and heating water connections after the DHW cylin-
der has been depressurised.
