NOTE! The pipe from the tank/double jacket must be
drained of water before the air can be removed. This
means that the system is not necessarily vented,
despite water emerging from the safety valve (52)
when it is opened for the first time.
■
Vent VVM 240 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.
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
the button firmly).
Venting the heating system
Preparations
■
The water heater is filled by first opening a hot
water tap and then opening the filling valve (46) ful-
ly. This valve should then be fully open during oper-
ations. When water comes out of the hot water tap
this can be closed.
■
Open the filling valve (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 ris-
ing pressure. When the pressure reaches 2.5 (bar)
(approx. 25 mvp) a mixture of air and water starts
to emerge from the safety valve (52). The filling
valve is then closed (49).
■
Turn the safety valve (52) until the boiler pressure
reaches the normal working range (0.5 - 1.5 bar).
