Installation Procedure
• Be sure to perform works such as additional refrigerant
charging and pipe welding under the conditions of good
ventilation.
• Be sure to perform welding and piping works for
mechanical connections under the conditions that the
refrigerant does not circulate.
• When reconnecting the pipes, make sure to perform
flared-jointing newly to prevent refrigerant leakage.
• When working on the refrigerant pipes and the flexible
refrigerant connectors, be careful that they are not
damaged physically by surrounding objects.
• For installation with handling the R-32 refrigerant, use
the special tools for the R32 refrigerant (manifold gauge,
vacuum pump, charging hose, etc.).
• During tests never pressurize the appliances with a
pressure higher than the maximum allowable pressure(as
indicated on the nameplate of the unit).
• Never directly touch any accidental leaking refrigerant.
This could result in severe wounds caused by frostbite.
• Never install a dryer to this unit in order to guarantee its
lifetime.
• If the pipes require brazing ensure that OFN(Oxygen Free
Nitrogen) is flowing through the system.
• Nitrogen blowing pressure range is 0.02 to 0.05 MPa.
• If you need a pipe longer than specified in piping codes
and standards, you must add refrigerant to the pipe.
Otherwise, the indoor unit may freeze.
• While removing burrs, put the pipe face down to make
sure that the burrs do not get in to the pipe.
Step 7 Connecting up and removing
air in the circuit
CAUTION
• When installing, make sure there is no leakage. When
recovering the refrigerant, ground the compressor first
before removing the connection pipe. If the refrigerant
pipe is not properly connected and the compressor works
with the service valve open, the pipe inhales the air and
it makes the pressure inside of the refrigerant cycle
abnormally high. It may cause explosion and injury.
You should purge the air in the indoor unit and in the pipe. If
air remains in the refrigerant pipes, it affects the compressor.
It may cause reduction of cooling/heating capacity and
malfunction. Refrigerant for air purging is not charged in the
outdoor unit. Use Vacuum Pump as seen in the picture.
1 Remove the cover panel on the unit.

2 Remove the service valve caps.
3 Connect the pipes to the service valve with the flare nuts.
Hand-tighten the nuts to prevent stripping.
