that the water in the system has frozen.
Pipe
After pipe installation, but before insulating, the system’s
brine side has to be filled with water, vented and pres-
sure-tested. After this, the pipes have to be flushed and
vented. Finally, the system has to be filled with a 28%
mixture of ethylene glycol and water.
The heating medium side should also be flushed and
pressure tested with water.
NOTE
Pay attention to nearby electricity sources
when you are working with liquids.
NOTE
Always wear protective gloves before starting
work.
NOTE
Take care not to damage the environment in
the work area. Risk of flooding.
NOTE
Check that the components necessary for unit
operation are installed and connected to
GreenMaster-HP.
Ventilation

1. The fan (GQ2) can rotate freely and there are no
loose parts remaining in the fan chamber.
2. Connector (HR10) next to the fan is in position AUTO.
3. Air filters (HQ10) are clean and intact.
4. The heat exchanger’s (EP10) fins and pipes are clean
and intact.
5. The air ducts are correctly connected to GreenMas-
ter-HP.
6. Sensor (BP12) is connected correctly.
7. Any external accessories are correctly connected.
