Installation Procedure
English
Installation Procedure
• When working on the refrigerant pipes and the flexible
refrigerant connectors, be careful that they are not
damaged physically by surrounding objects.
• 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 2.9 to 7.3 psi(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 8 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.
The outdoor unit is loaded with sufficient R-410A
refrigerant. Do not vent R-410A into atmosphere: it is a
fluorinated greenhouse gas, covered by Kyoto Protocol,
with a Global Warming Potential (GWP) = 2088.
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 Connect each assembly pipe to the appropriate valve
on the outdoor unit and tighten the flare nut.
2 Referring to the illustration below, tighten the flare
nut on section D first manually and then with a torque
wrench, applying the following torque.
