11. Start filling slowly by closing filler connection (XL28).
Check that the pressure is gradually increasing using
pressure gauge (BP6).
12. When the pressure reaches 2.5 bar, close the valves
for the filler connections (XL27) and (XL28) simultan-
eously.
13. Turn off the filling pump.
14. Check whether there is any air left in the coil. Open
the heat exchanger’s (EP16) vent valve (QM21) to
remove any remaining air.
15. Leave the system in this state for 30 minutes.
16. Check that the pressure level has not dropped and
proceed to the next step. A pressure drop in the
system may be due to a leak in the system. If leaks
are discovered, they must be repaired. Then follow
the above steps again.
17. Open shut-off valve (QM34).
18. Disconnect the hoses (3) and (1).
NOTE
Carefully disconnect the hoses to prevent
flooding.
19. Go through the start guide for the GreenMaster-HP
(see page 35), keep checking the pressure level at
regular intervals for at least 8 hours.
NOTE
Make sure that the brine system does not con-
tain air before it is started up.. Failure to prop-
erly vent the system may result in damage to
components.
Filling and venting heating medium system
Filling
1. Open the filling valve (external, not included in the
product). Fill the climate system with water.
2. Open the vent valve (external, not included in the
product).
3. When the water that exits the vent valve is not mixed
with air, close the valve. After a while, the pressure
starts to rise.
4. Close the filling valve when the correct pressure is
obtained.
Venting
1. Vent GreenMaster-HP via a vent valve (external, not
included in the product) and other climate systems
via their respective vent valves.
2. Keep topping up and venting until all air has been
removed and the pressure is correct.
NOTE
Make sure that the heating medium system
contains no air, before start-up. Failure to
properly vent the system may result in damage
to components.
Start-up and inspection
Start guide
NOTE
There must be water in the climate system be-
fore the switch is set to " ".
1. Set switch (SF1) on GreenMaster-HP to position " ".
2. Follow the instructions in the display’s start guide.
If the start guide does not start when you start the
GreenMaster-HP, start it manually in menu 5.7.
TIP
Refer to the operating manual for a more in-
depth introduction to the control system in
GreenMaster-HP (operation, menus, etc.).
If the building is cooled when GreenMaster-HP starts,
the compressor may not be able to meet the entire de-
mand without having to use additional heating.
Commissioning
The first time the installation is started a start guide is
started. The start guide instructions state what needs to
carried out at the first start together with a run through
of the installation’s basic settings.
The start guide ensures that the start-up is carried out
correctly and, for this reason, cannot be skipped.
Caution
As long as the start guide is active, no function
in the installation will start automatically.
The start guide will appear at each restart of
the installation, until it is deselected on the last
page.
Caution
At start-up of GreenMaster-HP-30 to 60kW,
preheating of the compressors starts. Preheat-
ing continues until the temperature sensor
BT29 is stable 10 degrees greater than sensor
BP8 (for GreenMaster-HP-60kW this can take
up to 12 hours).
