INSTALLATION
4.2.2. Filling and de-aeration of the heat collection circuit
Accessories required for the filling and de-aeration of the ground circuit:
• mixing tank, 60 litres
• submersible pump fitted with a filter, lifting height approx. 30m
• water/ethanol or water/glycol mixture (1:1) with a frost resist-
ance of -16 °C
• reinforced hose 1” (2 pc.), length approx. 3 m
• connector 1” (1 pc.) (female)
• connector 3/4” (1 pc.) (female)
WORK STAGES
Please check that the ground circuit has been correctly connected.
NOTE! The following instructions are for ESi series. The filling and de-
airing is done similarly to EMi/ELi series but the valve gropup is built
during installation.
1. Remove the styrox packaging
protecting the group of fill
valves.
2. Detach the expansion vessel
from the foremost ball valve.
3. The foremost shut-off valve
(2) of the group of fill valves
must always be open.
4. Attach the submersible pump reinforced hose to the foremost ball
valve (3) in the group of fill valves and open the ball valve.
5. Attach a reinforced hose from the ball valve (4) at the back of the
group of fill valves to the fill container and open the valve.
NOTE! The flow direction has to be correct since there is a one
way valve installed between the cooling connections.
6. Fill the container with water/ethanol or water/glycol (frost r. -16
°C) mixture (ratio 1:1).
7. Bleed air from fill hoses by activating the submersible pump and
keeping the valve (1) open. When air has escaped, close the valve
(1) to start actual fluid circulation through the ground circuit.
8. Add fluid until the piping is full. Upon de-aeration, the unit’s own
brine circulation pump can be used to speed up fluid circulation.
• Check that the motor protection switch (QM1) is not on.
• Turn master switch (Q1) and control current switch (F10) on.
• The forced control of gound circuit pump can be activated
from the maintenance manual of ÄssäControl. Go to manual
control and choose manual control on and ground circuit 1 on.
• Turn the motor protection switch (QM1) on.
NOTE! When using the system’s own brine circulation pump for

de-aeration purposes, check that the flow direction of the separate
submersible pump is always the same as that of the unit’s pump.
9. Keep the submersible pump running until the fluid is clear and no
gurgling can be heard from the pipes. NOTE! De-aeration usually
takes several hours and helps to ensure that all the air is remove
from the system and will not cause any malfunctions once the
system is started. Leave no pressure in the network! Remove any
air from the evaporator through the de-aeration connection of the
pipe located between the ground circuit and the evaporator.
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 must be
closed in order to prevent fluids from running out.
Filling and de-aeration have now been completed.
4.2.3. Connections between heat pump and storage tank
The storage tank is connected to the ground source heat pump pursuant
to the connection diagram at the end of this manual. The connections for
the ground source heat pump are shown in the picture found in chapter
4.2.1. The factory setting for super heat valve can be found in the
technical specifications table. The setting can be adjusted in the mainte-
nance menu.
4.2.4. Heating and domestic hot water connections
Connect the heating and domestic hot water connections pursuant to
connection diagrams in the chapter 8. Connection diagrams.
