When removing flare nut of the indoor unit, first remove the nut of small diameter
side.
Prevent water from entering into the piping when connecting.
Be sure to tighten the flare nut to the specified torque with a torque wrench.
If the flare nut is overtightened, it may split after sometime and may cause refrigerant leak.
When using a control valve, make sure that the packing is not deteriorated and
avoid excessive tightening of the handle. Otherwise, gas may leak from the service
valve.
* Tightening torque must be as shown in the table below.
From the viewpoint of global environment
protection, air purge type should be vacuum
pump method.

Remove the valve head cap
of the service valve.
Remove the cap of valve core
and
connect the charge hose.
Connect the vacuum pump
adapter to the vacuum pump
and connect the charge hose
to the adapter.
Loosen the spindle of the service valve with small diameter
by 1 / 4 turn and tighten the spindle immediately after 5 to 6
seconds.
Remove the charging hose from the service valve.
Unscrew the spindle of both the
service valves in anticlockwise
direction to allow the flow of
refrigerant (unscrew halfway).
Tighten the cap of valve head.
Check and make sure that there
is no gas leakage.
Fully tighten the “ Hi ” shuttle of the
manifold valve and completely unscrew
the “Lo” shuttle. Run the vacuum pump.
(Adapter is switched on)
Make sure the meter
reaches -0.1MPa (-76cmHg)
during pumping.
Closed
When pumping starts, slightly loosen
the flare nut to check if air sucked in.

From the viewpoint of global environment protection, refrigerant
should be recovered (pumped down) when the air conditioner is
transferred or removed.
Perform force-cooling operation for about 5 minutes as a
preliminary operation.
Tighten the spindle of the service valve at small diameter side in
clockwise direction.
Continue the force-cooling operation for another 1-2 minutes, and
then tighten the spindle of the service valve at large diameter side
in clockwise direction.
Stop the force-cooling operation.
Gas Leakage Inspection
Please use gas leakage detector
to check if leakage occurs at
connection of Flare nut as shown
on the right.
If gas leakage occurs , further tighten the
connection to stop leakage. (Be sure to use
R410A detector.)
After pumping for about 10 -15 minutes,
completely loosen the “ Lo ” shuttle and
switch off the vacuum pump . (Adapter is
switched off)
Otherwise the nut of big diameter side will fly out.
WARNING
Detail of Cutting the Connecting Cord
• If the supply cord is damaged, it must be replaced by a special cord (Maker’s service parts) available from the manufacturer
or its service agent.
• The naked part of the wire core should be 10mm fix it to the terminal tightly. Then try to pull the individual wire to check if the
contact is tight. Improper insertion may burn the terminal.
• Be sure to use only wire specified for the use of air-conditioner.
• Please refer to the manual for wire connection, the wiring technique should meet the standard of the electrical
installation.
• Leave some space in the connecting cord for maintenance purpose and be sure to secure it with the cord band.
• Secure the connecting cord along the coated part of the wire using the cord band. Do not exert pressure on the wire as this
may cause overheating or fire.
• There is a AC voltege of 220V between the 1 and 2(N) terminals. Therefore, before servicing, be sure to remove the plug from
the AC outlet.
CAUTION
•For wire connection of the Indoor unit, you need to remove the front cover, the low cover
under the body of the unit and terminal cover.
•Remove the cover from the terminal base and screw the cable.
