INSTALLER MANUAL

10. When de-aeration has been completed turn the motor protection

switch QM1 off and also manual control function off.

11. Open shut-off valve (1) at the back of the group of fill valves.

12. Close both ball valves (3) and (4).

13. Remove the fill hoses.

14. Fasten the expansion vessel back in its place in the foremost ball

valve (3) in the group of fill valves.

15. Remove the safety valve on the expansion vessel.

16. Fill ¾ of the expansion vessel with water/ethanol or water/glycol

mixture.

17. Fasten the safety valve to the expansion vessel.

18. Open the foremost shut-off valve (3) in the group of fill valves.

19. Remove and clean the net strainer (5) on the mud separator,

repeat this several times, if necessary. The red-handled valves (1)

and (2), as well as the valve under the fill container (3) must be

closed in order to prevent fluids from running out.

Filling and de-aeration have now been completed.

4.2.3. Heating and domestic
hot water connections

Remove the crown panel from the
geothermal heat pump’s upper part
for the duration of installation works
by undoing the two screws shown in
the picture. Pull the crown panel directly forward and lift it off the heat
pump. Make the heat distribution and domestic water connections as
shown in the picture below.

Varaajan täytön yhteydessä varaajassa olevan ilman on päästävä vapaasti

poistumaan. Huom! Ei ilmaventtiilin tai varoventtiilin kautta.

While filling the storage tank outgoing air has to be freely deflated.

NB! Not via air valve or safety valve.

Heating connection

Heat distribution circuit surface sensors located on top of the storage tank
must be installed to the distance of approx. 0.5 m from the three-way or
four-way valve. Circuit HD1 is always the main heating circuit (rooms, for
example); it is used for higher temperature (radiator heating, for example). In
case of compressor malfunction, the electric heating element heats the cir

cuit HD1 more efficiently. Circuit HD2 is used in radiator-heated buildings for
the possible floor heating share or for other purposes (e.g., humid rooms).

Speed controlling of the heat circulation pumps

Grundfos UPM3 AUTO heat circulation pump which is used in a HD cir

cuit can be set in three different controlling modes: proportional pressure
mode, constant pressure mode, constant curve mode.

Factory setting is

proportional pressure mode 3.

In radiator network constant pressure

mode 1 or 2 can be used if sound of the flow water is disturbingly high.

Proportional pressure mode
