Cautions for handling stop valve

For Sky Air or room air conditioner indoor units only:
The stop valves for BP unit-outdoor connecting piping are closed
at shipment from the factory.

For VRV indoor units only:
The stop valves for indoor-outdoor connecting piping are closed
at shipment from the factory.

The names of parts of the stop valve are shown in the figure.

Since the side boards may be deformed if only a torque wrench
is used when loosening or tightening flare nuts, always lock the
stop valve with a wrench and then use a torque wrench.
Do not place wrenches on the valve cover.

Do not apply force on the valve cover, this may result in a
refrigerant leak.

For cooling operation under low ambient temperature or any
other operation under low pressure, apply silicon pad or similar
to prevent freezing of the gas stop valve flare nut (see figure).
Freezing of the flare nut may cause refrigerant leak.

9.3.

How to use the stop valve

Use hexagonal wrenches 4 mm and 6 mm.

Opening the valve

1.

Place the hex wrench on the valve bar and turn counter-
clockwise.

2.

Stop when the valve bar no longer turns. It is now open.

Closing the valve

1.

Place the hex wrench on the valve bar and turn clockwise.

2.

Stop when the valve bar no longer turns. It is now closed.

9.4.

Cautions for handling the valve cover

The valve cover is sealed where
indicated by the arrow.
Take care not to damage it.

After operating the valve, be sure to
tighten the valve cover properly.

Check for refrigerant leakage after tightening the cap.

9.5.

Cautions for handling service port

After the work, tighten the valve cover in place.

Tightening torque: 11.5~13.9 N•m

9.6.

Precautions when connecting field piping and 
regarding insulation

For Sky Air or room air conditioner indoor units only:
Be careful not to let the BP unit and outdoor branch piping come
into contact with the compressor terminal cover.
If the liquid-side piping insulation might come into contact with it,
adjust the height as shown in the figure below. Also, make sure
the field piping does not touch the bolts or outer panels of the
compressor.

For Sky Air or room air conditioner indoor units only:
When the outdoor unit is installed above the BP unit and indoor
unit the following can occur:
The condensated water on the stop valve can move to the BP
unit. To avoid this, please cover the stop valve with sealing
material.

For VRV indoor units only:
Be careful not to let the indoor and outdoor branch piping come
into contact with the compressor terminal cover.
If the liquid-side piping insulation might come into contact with it,
adjust the height as shown in the figure below. Also, make sure
the field piping does not touch the bolts or outer panels of the
compressor.

For VRV indoor units only:
When the outdoor unit is installed above the indoor unit the
following can occur:
The condensated water on the stop valve can move to the
indoor unit. To avoid this, please cover the stop valve with
sealing material.

If the temperature is higher than 30°C and the humidity is higher
than RH 80%, then the thickness of the sealing materials should
be at least 20 mm in order to avoid condensation on the surface
of the sealing.

Be sure to insulate the liquid and gas-side field piping and the
refrigerant branch kit.

(The highest temperature that the gas-side piping can reach is
around 120°C, so be sure to use insulating material which is
very resistant.)

Make sure to keep the valve open during operation.
