Commissioning and adjusting

Preparations

1.
Check that the switch (SF1) is in position "
2. Check that the drain valve is fully closed and that the
temperature limiter (FQ10) has not deployed.
3. Compatible NIBE air/water heat pump must be equipped
with a control board that, as a minimum, has the soft-
ware version listed on page 17. The control board's
version is shown in the heat pump's display (if applic-
able) at start-up.

Filling and venting

FILLING THE HOT WATER COIL
1. Open a hot water tap in the house.
2. Open the externally mounted shut-off valve. This valve
should then be fully open during operations.
3. When water comes out of the hot water tap, the hot
water coil is full and the tap can be closed.
FILLING THE CLIMATE SYSTEM
1. Open the vent valves (QM20).
2. Open the externally mounted filler valve. The boiler
section and the rest of the climate system are filled with
water.
3. When the water exiting the vent valves (QM20) is not
mixed with air, close the vent valves. After a while the
pressure rises on the externally mounted pressure
gauge. When the opening pressure for the externally
mounted safety valve has been reached, it starts to re-
lease water. Close the filler valve.
4. Open the externally mounted safety valve until the
pressure in VVM 500 falls to the normal working range
(approx. 1 bar) and check that there is no air in the sys-
tem by turning the vent valves (QM20).

".
2. Vent VVM 500 through the vent valves (QM20) and
other climate systems through their relevant vent
valves.
3. Keep topping up and venting until all air has been re-
moved and the pressure is correct.
