Preparations
Connect AMS 10 to ACVM 270 (refrigerant pipe and wir-
ing) and connect ACVM 270 to the climate system.
Filling the climate system
1. Ensure that the pressure gauge (BP5) is visible.
2. Connect a hose to the filling valve (QM1) and open
the valve to fill the boiler and the radiator system.
3. After a while note that the pressure on the pressure
gauge (BP5) can be seen to rise.
4. When the pressure has reached about 0.25 MPa (2.5
bar) the safety valve (FL2) starts to release air mixed
with water. Close the filling valve (QM1).

Venting the climate system
Vent ACVM 270 through the safety valve (FL2), bleed
screws (QM20, QM24 and QM60), and the rest of the cli-
mate system through the relevant vent valves.
Keep topping up and venting until all air has been removed
and the correct pressure has been obtained.
Filling the hot water coil
The hot water coil is filled by opening a hot water tap.

2. Switch on the circuit breaker and check that the mini-
ature circuit breaker (FA1) in ACVM 270 is on.
3. Set switch (SF1) to " 1" (the switch should be switched
on 6 hours before the compressor can be started).
When switch (SF1) is set to "0" - wait at least 1 minute

menu 8.3.1.
9. Set the max immersion heater output on knob (R25).
Check the value in menu 8.3.2.
10. Select the desired curve slope in menu 2.1.2 and set
the parallel offset using the knob. Also see section
Default setting on page 11.
11. Check that the hot water temperature in menu 1.0
exceeds 25 C.
12. When point 11 has been carried out, select operating
mode "Auto".
The heat pump starts 30 minutes after the outdoor unit is
powered up if there is a demand.
Setting system flow heating
1. Ensure that the heat pump produces heating for the
climate system.
2. Select “On” in menu 9.6.2.
3. Select ”40
4. Check the supply and return temperatures in menu
2.5. Adjust the circulation pump speed in menu 2.1.5
so that the difference between these temperatures is
according to the diagram below.
5. Select ”Off” in menu 9.6.2.
