Filling the system
Filling the heating system:
Figure 38: 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.
