Preparations
1.
Ensure that F1226 has not been damaged during
transport.
2.
Check that the switch (SF1) is in position " ".
3.
Check for water in the hot water heater and climate
system.
Caution
Check the miniature circuit-breaker and the
motor protection breakers. They may have
tripped during transportation.
NOTE
Do not start F1226 if there is a risk that the wa-
ter in the system has frozen.
Filling and venting
Caution
Insufficient venting can damage internal com-
ponents in F1226.
Filling and venting the climate system
Filling
1.
Open the venting valve (QM22).
2.
When the water that exits the venting valve (QM22)
is not mixed with air, close the valve. After a while
the pressure starts to rise.
3.
Close the filling valve when the correct pressure is
obtained.
Venting
1.
Bleed the heat pump via a vent valve (QM22) and
the rest of the climate system via their relevant vent
valves.
2.
Keep topping up and venting until all air has been
removed and the pressure is correct.
NOTE
The pipe from the coil in the container must be
drained of water before air can be released. This
means that the system is not necessarily bled
despite the flow of water when the vent valve
(QM22) is opened.
Filling the hot water heater
1.
Open a hot water tap in the house.
2.
Fill the hot water heater through the cold water
connection (XL3).
3.
When the water that comes out of the hot water
tap is no longer mixed with air, the water heater is
full and the tap can be closed.
Filling and venting the brine system
When filling the brine system, mix the water with anti-
freeze in an open container. The mixture should be
protected against freezing down to about -15 °C. The
brine is filled by connecting a filling pump.
1.
Check the brine system for leakage.
2.
Connect the filling pump and return line on the brine
system’s filling connection (see image).
3.
If alternative 1 (level vessel) is used, close the valve
under the level vessel (CM2).
4.
Close the three way valve in the filler connector (ac-
cessory).
5.
Open the valves on the filler connector.
6.
Start the filling pump.
7.
Fill until liquid enters the return pipe.
8.
Close the valves on the filler connector.
9.
Open the three way valve in the filler connector.
10.
If alternative 1 (level vessel) is used, open the valve
under the level vessel (CM2).
