Refrigerant piping
Install the refrigerant pipe securely during the installation
work before operating the air conditioner. If the compressor
is operated with the valve open and without refrigerant pipe,
the compressor sucks air and the refrigeration cycles is over
pressurized, which may cause a injury.
Tighten the are nut with a torque wrench in the specied manner.
Excessive tighten of the are nut may cause a crack in the are
nut after a long period, which may result in refrigerant leakage.
After the installation work, conrm that refrigerant gas does not
leak. If refrigerant gas leaks into the room and ows near a re
source, such as a cooking range, noxious gas may be generated.
When the air conditioner has been installed or relocated,
follow the instructions in the Installation Manual and purge
the air completely so that no gases other than the refrigerant
will be mixed in the refrigerating cycle. Failure to purge the air
completely may cause the air conditioner to malfunction.
Nitrogen gas must be used for the airtight test.
The charge hose must be connected in such a way that it is not
slack.
Electrical wiring
Only a qualied installer(*1) or qualied service person(*1) is
allowed to carry out the electrical work of the air conditioner.
Under no circumstances must this work be done by an
unqualied individual since failure to carry out the work properly
may result in electric shocks and/or electrical leaks.
To connect the electrical wires, repair the electrical parts or
undertake other electrical jobs, wear gloves to provide protection
for electricians and from heat, insulating shoes and clothing
to provide protection from electric shocks. Failure to wear this
protective gear may result in electric shocks.
Use wiring that meets the specications in the Installation
Manual and the stipulations in the local regulations and laws.
Use of wiring which does not meet the specications may give
rise to electric shocks, electrical leakage, smoking and/or a re.
Connect earth wire. (Grounding work) Incomplete grounding
causes an electric shock.
Do not connect earth wires to gas pipes, water pipes, and
lightning conductor or telephone earth wires.
After completing the repair or relocation work, check that the
earth wires are connected properly.
Install a circuit breaker that meets the specications in the
Installation Manual and the stipulations in the local regulations
and laws.
Install the circuit breaker where it can be easily accessed by the
agent.
When installing the circuit breaker outdoors, install one which is
designed to be used outdoors.
Under no circumstances the power wire must not be extended.
Connection trouble in the places where the wire is extended may
give rise to smoking and/or a re.
Electrical wiring work shall be conducted according to law and
regulation in the community and Installation Manual.
Failure to do so may result in electrocution or short circuit.
Test run
Before operating the air conditioner after having completed the
work, check that the electrical control box cover of the indoor unit
and service panel of the outdoor unit are closed, and set the circuit
breaker to the ON position. You may receive an electric shock if
the power is turned on without rst conducting these checks.
If there is any kind of trouble (such as an error display has
appeared, smell of burning, abnormal sounds, the air conditioner
fails to cool or heat or water is leaking) has occurred in the air
conditioner, do not touch the air conditioner yourself but set the
circuit breaker to the OFF position, and contact a qualied service
person. Take steps to ensure that the power will not be turned on
(by marking “out of service” near the circuit breaker, for instance)
until qualied service person arrives.
Continuing to use the air conditioner in the trouble status may
cause mechanical problems to escalate or result in electric shocks
or other trouble.
