Figure 50: Filling the heating system
-
Fill the heating system via the drain valve.
-
Vent the pipework.
NOTE
For easier filling, the 3-way switching
valve (multifunctional assembly) is set
to a position suitable for filling at the
factory. The cable from the switching
valve to the OTE controller has been
disconnected at the factory.
➔
Once the system is successfully
filled, connect the plugs
PIN3/N/PE
and PIN4/N/PE on the OTE
controller.
Filling the DHW tank:
- Fill the DHW tank via the cold water
connection.
-
Open all downstream draw-off valves
until the appliance is filled and the
pipework is free from air.
- Adjust the flow rate. Observe the
maximum permissible flow rate with fully
opened valve (see Specification). If
necessary, reduce the flow rate at the
throttle on the safety assembly.
-
Carry out a leakage test.
- Test the safety valve.
