Filling and venting
FILLING THE CLIMATE SYSTEM
Fill with water using the filler valve in the heat pump.
VENTING THE CLIMATE SYSTEM
1. Vent SAM S42 through the vent valves (QM20.1),
(QM20.2), (QM23) and the rest of the climate system
through its respective vent valves.
2. Keep topping up and venting until all air has been re-
moved and the pressure is correct.
Caution
Check that the system has been vented prior to
the heating season. Air in the supply air module
entails a risk of frost damage in cold weather
conditions.

SAM S42 is started.
1. Set switch (SF1) on SAM S42 in position "1".
2. Start the heat pump.
3. Follow the instructions in the display’s start guide. If the
start guide does not start when you start the heat pump,
you can start it manually in menu 7.7.
SETTING THE VENTILATION
Ventilation must be set according to applicable standards.
The supply air flow is adjusted to approx. 80% of the exhaust
air flow. The setting is made in menu 5.1.6.
Even if ventilation is roughly set at installation it is important
that a ventilation adjustment is ordered and permitted.
NOTE
Order a ventilation adjustment to complete the
setting.
