Commissioning and adjusting 15
For the Installer
FIGHTER 200P
■ Vent the electric boiler through the safety valve
(52) and the rest of the heating system through the
relevant venting valves.
■ Keep topping up and venting until all air has been
removed and the pressure is correct.
Venting the heating system
Check that the switch (8) is set to “0”.
Check that valves (44) and (50) are fully open and
that the temperature limiter (6) has not tripped (press
firmly the knob). FIGHTER 200P is supplied with a
limiting valve (5) mounted on the outlet pipe. This one
allows to set a maximum outlet temperature in order
to protect the floor in an existing floor heating system.
This valve is adjustable between 38 and 55 °C. The ex
works setting is 38 °C. Turn setting knob (19) clock-
wise to lower the temperature and counter-clockwise
to lower the same until desired setting is reached. A
quarter turn is equal to 5 °C.

■ 
The water heater is filled by opening a hot water tap.
When water comes out of the hot water tap this can
be closed.
■ Connect enclosed flexible hose (147) between con-
nection (149) and connection (150) (the hose is
mounted at the unit when this is delivered). Open
filling valves (151) and (49). The boiler part of the
heat pump and the radiator system are now filled
with water.
■ After a while the pressure gauge (42) will show
rising pressure. When the pressure reaches 2.5
(bar) (approx. 25 mvp) a mixture of air and water
Filling the water heater
and the heating system
starts to emerge from the safety valve (52). The fil-
ling valves (151) and (49) are then closed.
■ Turn the safety valve (52) until the boiler pressure
reaches the normal working range (0.5 - 1.5 bar).
■ When the filling procedure is finished the flexible
hose (147) shall be removed.
