The fi gure below shows the name of each part required in
•
handling the stop valve. At the time of shipment, the stop
valve is closed.
Valve cap
Service port
Field piping
connection part
Valve stem
Silicon sealant
(Take care not to generate cavity.)
If only a torque wrench is used to loosen or tighten the fl are
•
nut, the side plate may be distorted. Make sure to fi x the
stop valve with a spanner, then loosen or tighten the fl are
nut with a torque wrench.

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), seal suffi ciently the fl are nut
in the stop valve on the gas line with silicon sealant to
prevent freezing.
Cautions on handling the valve cap
The valve is sealed in the arrow area. Take care not to
•
damage the arrow area.
Valve cap
Stop valve
(valve cap attachment area)
After handling the valve, make sure to tighten the valve cap
•
securely.
Liquid line
Gas line
10.0~12.2 ft·lbf
16.6~20.3 ft·lbf
Cautions on handling the service port
Use charge hose equipped with push in the work.
•
After the work, make sure to tighten the valve cap securely.
•
Tightening torque.....8.5~10.3 ft·lbf
[Stop valve operation method]
Prepare hexagon wrenches (whose size is 4 mm and 6 mm).
How to open the stop valve
Insert a hexagon wrench into the valve stem, and turn the
1.
valve stem counterclockwise.
When the valve stem cannot be turned any more, stop
2.
turning. Now, the valve is open.
How to close the stop valve
Insert a hexagon wrench into the valve stem, and turn the
1.
valve stem clockwise.
When the valve stem cannot be turned any more, stop
2.
turning. Now, the valve is closed.

DANGER
Do not ground units to water pipes, telephone wires or
•
lightning rods because incomplete grounding could cause a
severe shock hazard resulting in severe injury or death, and
to gas pipes because a gas leak could result in an explosion
which could lead to severe injury or death.
WARNING
Disconnect all power to unit to avoid possible electric shock
•
during installation.
Use only specifi ed wire and connect wires to terminals
•
tightly. Be careful that wires do not place external stress on
terminals. Keep wires in neat order so as to not to obstruct
other equipment. Incomplete connections could result in
overheating, and in worse cases, electric shock or fi re.
For the details, refer to “
7-3 Power supply wiring connec-
tion procedure
”.
CAUTION
<To electrician>
Do not operate the air conditioner until the refrigerant piping
•
work is completed.
(Operating the air conditioner before the refrigerant piping
work is completed may damage the compressor.)
Install a ground fault circuit interrupter.
•
(The inverter is provided in the air conditioner. In order to
prevent malfunction of the ground fault circuit interrupter
itself, use a breaker resistant to higher harmonics.)
Electricians having suffi cient knowledge should perform the
•
electric wiring work.
All wiring must comply with local electrical codes and Na-
tional Electrical Code (NEC).
