(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

Cautions on handling the service port
Use charge hose equipped with push in the work.

[Stop valve operation method]
Prepare hexagon wrenches (whose size is 4 mm and 6 mm).
How to open the stop valve

1.
valve stem counterclockwise.
When the valve stem cannot be turned any more, stop
2.
turning.
N
ow, the valve is open.
How to close the stop valve

ELECTRIC WIRING WORK

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 an earth leakage circuit interrupter.
•
(The inverter is provided in the air conditioner. In order to
prevent malfunction of the earth leakage circuit interrupter
itself, use a breaker resistant to higher harmonics.)
Electricians having suffi cient knowledge should perform the
•
electrical wiring work.
All wiring must comply with local electrical codes and
N
a-
tional Electrical Code (
N
EC).
