Commissioning and adjusting
Starting
• Set the switch (8) to “2” in order to accelerate the-
heating of the radiator system. NOTE! The compres-
sor has a start delay of about 10 minutes in the start
mode.
• Set the designed capacity on the circulation pump us-
ing its switch (35). See the section “Pipe connections”
– ”Pump and pressure drop diagram”. Make sure that
the switch is not in an intermediate position.
Readjustment
During the initial running period, air is given off by the
heating water, and venting can be necessary. If bubbling
sounds can be heard from the heat pump, the entire sys-
tem requires further venting. NOTE! The safety valve (52)
also acts as a manual venting
valve. Operate it with care, since it opens quickly.
Draining the heating system
The hot water can be drained off through the drain valve
(51) using an R15 (1/2”) hose coupling. Remove the cover
(80) from the valve (51). Screw on the hose coupling and
open the valve (51). Open the safety valve (52) to let air
into the system.
Draining the water heater
This is how to drain the water heater:
• Disconnect the overflow pipe from the drain connec-
tion and connect a hose to a draining pump instead.
Where no draining pump is available, the water can be
released into the overflow funnel (99).
• Open the drain valve (47).
• Open a hot water tap to let air into the system. If this
is not enough, undo the pipe coupling (74) on the hot
water side and pull out the pipe.
Setting the ventilation
The ventilation flow and setting are given on the ventila-
tion drawing. See section “Ventilation connection”, “Fan
diagram".
1. Remove any switches for ventilation changes from ter-
minal block (11), pos 8-10.
2. Ensure that the heat pump’s boiler section is filled with
water.
3. Make sure that all outdoor air devices are fully open.
4. Adjust the normal ventilation speed using knob R52.
5. Start the heat pump with compressor operation. The
compressor can be quick-started by pressing in button
S202 on the circuit board (34).
6. Adjust the high fan capacity using knob R51. To en-
sure the lowest possible noise level, adjust the fan to
the lowest possible capacity.
7. Set correct ventilation flows on the house exhaust air
valves.
8. Reinstall any switches for ventilation changes in termi-
nal block (11).
The ventilation flow must never be lower than 100 m
3
/h.
At the time of commissioning complete
