Never use the refrigerant charged in the outdoor unit for air purging.
Insufficient refrigerant will lead to failure.
Thermal Insulation Finishing Work
Wrap tape around the thermal
insulation of gas pipe and liquid
pipe.
Gas Line
Liquid Line
Liquid Line Stop Valve
Gas Line Stop Valve
Cover the liquid line
with thermal insulation.

Vacuum Pump
Manifold
Gauge
Cover the flare nut and union of the
piping connection with thermal insulation.
Insulate the liquid pipe for
prevention of the capacity
decrease according to the
ambient air conditions and
the dewing on the pipe surface
by the low pressure.
Check to ensure that there is
no gas leakage. When large
amount of the refrigerant leaks,
the troubles as follows may occur;
1. Oxygen Deficiency
2. Generation of Harmful Gas
Due to Chemical Reaction
with Fire.

At the test run, fully open the spindle.
If not fully opened, the devices will be damaged.
An excess or a shortage of refrigerant is the main
cause of
damages
to the units.
Charge
the
correct refrigerant quantity according
to
the
description
of label
at the
inside
of service
cover.
Check for refrigerant leakage in detail. If a large
refrigerant leakage occurs, it will cause difficulty
with
breathing
or harmful
gases would
occur
if
a
fire
was
being
used
in
the
room.

according to each country’s regulation such as

follo ing
actions:
Critical Concentration

1) Provide a gas leakage detector and exhaust fan
controlled by its gas leakage detector.
2) Provide effective opening the wall or door for ventilation to next door so that the critical gas concentration
be maintained lower than the above value. (Provide an opening
than 0.15% of
floor surface
at the lower
part of a door.)
● Special Attention Regarding Refrigerant Gas Leakage
Pay attention to the critical gas concentration to avoid accidental refrigerant gas leakage before
installing
air conditioning systems.
