When it is expected that the operating pressure will be low (for
example, when cooling will be performed while the outside air
temperature is low), sufficiently seal the flare nut in the stop
valve on the gas line with silicon sealant to prevent freezing.

Opening/closing the stop valve

Opening the stop valve
1. Remove the valve cover.
2. Insert a hexagon wrench (liquid side: 4 mm/gas side: 6 mm) into
the valve stem and turn the valve stem counterclockwise.
3. When the valve stem cannot be turned any further, stop turning.
The valve is now open.
Closing the stop valve
1. Remove the valve cover.
2. Insert a hexagon wrench (liquid side: 4 mm/gas side: 6 mm) into
the valve stem and turn the valve stem clockwise.
3. When the valve stem cannot be turned any further, stop turning.
The valve is now closed.

Cautions on handling the stem cap

The stem cap is sealed where
indicated by the arrow. Take care not
to damage it.
After handling the stop valve, make
sure to tighten the stem cap securely.
For the tightening torque, refer to the
table below.
Check for refrigerant leaks after tightening the stem cap.

Cautions on handling the service port

Always use a charge hose equipped with a valve depressor pin,
since the service port is a Schrader type valve.
After handling the service port, make sure to tighten the service
port cap securely. For the tightening torque, refer to the table
below.
Check for refrigerant leaks after tightening the service port cap.

Cutting out the two slits makes it possible to install as shown in
the figure "Field pipes in 4 directions".
(Use a metal saw to cut out the slits.)
To install the connecting pipe to the unit in a downward direction,
make a knockout hole by penetrating the centre area around the
knockout hole using a Ø6 mm drill (4x). (See figure "Field pipes
in 4 directions".)
After knocking out the knockout hole, it is recommended to apply
repair paint to the edge and the surrounding end surfaces to
prevent rusting.
When passing electrical wiring through the knockout holes,
remove any burrs from the knockout holes and wrap the wiring
with protective tape to prevent damage.
