Air purging
Use only a vacuum pump to purge air from the piping.
NEVER use the system compressor as a vacuum pump.
NEVER use the unit refrigerant gas to purge the connecting
pipes.
No additional refrigerant has been provided in the unit for this
purpose.
Remove the caps from the two and three-way valves.
Create a vacuum with a vacuum pump connected to the service
connection of the suction shut-off valve, as shown, keeping the
shut-off valves completely shut until a 50 Pa (0.5 mbar) vacuum
has been reached.
Now open the two-way valve for 3 sec., then quickly shut it to check
for possible leaks.
After the leak check, fully open the two and three-way valves.
Replace caps and check for leaks.

WARNING:
During heat pump operation unit will undergo several defrost cycles to
eliminate ice that might possibly collect on the outdoor unit in very low
ambient temperatures.
In these cycles, fan speed will automatically reduce and cannot be
varied until defrost cycle is completed.
Notes: 1. Data referred to the outdoor unit only.
2. According to ISO 5151.2/T1.
3. According to ISO 5151.2/High+.
4. 38GLS units are provided with head pressure control
suitable up to –15°C ambient temperature (size 07 and 09
up to –5°C).

Once all connections have been completed, check for leaks by
using a leak detector specific for HFC refrigerants.
Finally wrap the valves and pipes with anti-condensate insulation
and tighten this with tape, without exerting too much pressure on
the insulation.
Repair and cover any possible cracks in the insulation.
Fix the pipes to the wall with hooks or conduits.
