(5) Connect the gauge mani-fold using

charging hoses with a nitrogen cylinder to
the check joints of the liquid line and the
gas line stop valves.
Perform the air-tight test.
Do not open the stop valves.  Apply
nitrogen gas pressure of 4.15MPa.

(6) Check for any gas leakage at the flare nut

connections, or brazed parts by gas leak
detector or foaming agent.

(7) After the air tight test, release nitorogen

gas.

Vacuum Pumping

(1) Connect a mani-fold gauge to the check

joints at the both sides.

Continue vacuum pumping work until the
pressure reaches -756mmHg or lower for
one to two hours.

(2) After vacuum pumping work, stop the

mani-fold valve’s valve, stop the vacuum
pump and leave it for one hour.  Check to
ensure that the pressure in the mani-fold
gauge does not increase.

(3) Fully open the gas valve and liquid valve.

NOTES:

1. When the spindle cap for stop valve is

removed, the gas accumulated at O-ring or
screws is released and may make sound.  This
phenomenon is NOT a gas leakage.

2. This unit is only for the refrigerant R410A.  The

manifold gauge and the charging hose should
be exclusive use for R410A.

3. If vacuum degree of -0.1MPa (-756mmHg) is

not available, it is considered of gas leakage or
entering moisture.  Check for any gas leakage
once again.  If no leakage exists, operate the
vacuum pump for more than one to two hours.

Indoor Unit

Thermal Insulation Finishing Work

Cover the flare nut and union of the 
piping connection with thermal insulation.

Cover the liquid line 
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.

(4) This system is not necessary to charge

refrigeration less than 30m of the actual
piping length.  If the total piping length is
more than 30m, it is necessary additional
refrigerant charge.

(5) Check for any gas leakage by gas leak

detector or forming agent.  Use the
foaming agent which does not generate the
ammonia (NH

3

) by chemical reaction.  The

recommended forming agent are as shown
below.  Do not use general household
detergent for checking.

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 trouble 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.

Never use the refrigerant charged in the outdoor unit for air purging.
Insufficient refrigerant will lead to failure.
