• When piping work is completed, it is necessary to purge the air and check for gas leakage
1) Do not mix any substance other than the speci
fi
ed refrigerant (R32) into the refrigeration cycle.
2) When refrigerant gas leaks occur, ventilate the room as soon and as much as possible.
3) R32, as well as other refrigerants, should always be recovered and never be released directly into the environment.
4) Use a vacuum pump for R32 exclusively. Using the same vacuum pump for different refrigerants may damage the vacuum pump or the unit.
WARNING
• If using additional refrigerant, perform air purging from the refrigerant
pipes and indoor unit using a vacuum pump, then charge additional
refrigerant.
• Use a hexagonal wrench (4mm) to operate the stop valve rod.
• All refrigerant pipe joints should be tightened with a torque wrench at
the speci
fi
ed tightening torque.

1) Connect projection side of charging hose (which comes from gauge manifold) to gas stop valve’s service port.
2) Fully open gauge manifold’s low-pressure valve (Lo) and completely close its high-pressure valve (Hi).
(High-pressure valve subsequently requires no operation.)
3) Do vacuum pumping and make sure that the compound pressure gauge reads - 0.1MPa ( - 760mmHg)*

.
4) Close gauge manifold’s low-pressure valve (Lo) and stop vacuum pump. (Keep this state for a few minutes to
make sure that the compound pressure gauge pointer does not swing back.)*

.
5) Remove covers from liquid stop valve and gas stop valve.
6) Turn the liquid stop valve’s rod 90 degrees counterclockwise with a hexagonal wrench to open valve.
Close it after 5 seconds, and check for gas leakage. Using soapy water, check for gas leakage from indoor
unit’s
fl
are and outdoor unit’s
fl
are and valve rods. After the check is complete, wipe all soapy water off.
7) Disconnect charging hose from gas stop valve’s service port, then fully open liquid and gas stop valves.
(Do not attempt to turn valve rod beyond its stop.)
8) Tighten valve caps and service port caps for the liquid and gas stop valves with a torque wrench at the speci
fi
ed torques.
*1. Pipe length vs. vacuum pump run time
Pipe length
Up to 15 metres
More than 15 metres
Run time
Not less than 10 min.
Not less than 15 min.
*2. If the compound pressure gauge pointer swings back, refrigerant may have water content or a loose pipe joint may exists.
Check all pipe joints and retighten nuts as needed, then repeat steps 2) through 4).

PUMP DOWN OPERATION
In order to protect the environment, be sure to pump down when relocating or disposing of the unit.
1) Remove the valve lids from liquid stop valve and gas stop valve.
2) Carry out forced cooling operation.
3) After
fi
ve to ten minutes, close the liquid stop valve with a hexagonal wrench.
4) After two to three minutes, close the gas stop valve and stop forced cooling
