3.
Fill the lower section of the condensate trap with water
up to 10 mm below the upper edge of the condensate
discharge pipe.
4.
Re-insert the float

Note
Check that the float is present in the con-
densate trap.

9.4
Switching on the product
▶
Switch on the product via the main switch installed on-
site.
9.5
Avoiding danger arising from insufficient
water pressure
The filling pressure must be between 0.10 and 0.15 MPa
(1.0 and 1.5 bar).
If the heating installation extends over several storeys,
higher filling pressures may be required to avoid air entering
the heating installation.
If the water pressure falls below 0.05 MPa (0.5 bar), the
value flashes in the display.
If the water pressure falls below 0.03 MPa (0.3 bar), the
product switches off. The display shows 0.0 MPa (0.0 bar).
Fault

is stored in the fault list.
▶
Top up the water in the heating installation to start up the
product again.
◁
The pressure value flashes in the display until a
pressure of 0.05 MPa (0.5 bar) or higher has been
reached.
9.6
Flushing the heating installation for the first
time ("cold")
Note
The complete heating system must be flushed
at least twice: Once with cold water and once
with hot water in accordance with the following
instructions.
1.
Check whether all thermostatic radiator valves and both
service valves on the product are open.
2.
Connect a hose to the drain valve that is located at the
lowest position in the heating system.
3.
Open the radiator valves and the drain valves so that
the water can drain quickly. Start at the next point in the
installation and open the purging valves on the radiators
so that the contaminated water can completely drain.
4.
Close the draining cocks.
5.
Refill the heating system with water.
6.
Check that the expansion relief valve of the heating
system is functioning correctly by turning the handle
on the valve.
7.
Check the pressure in the heating system and top up
with water if necessary.
8.
Close the filling valve and the cold water tap.
9.7
Filling and purging the heating installation
Preliminary work
▶
Flush the heating installation through.
