the refrigeration cycles is over pressurized, which may cause an
injury.
• Tighten the flare nut with a torque wrench in the specified manner.
Excessive tightening of the flare nut may cause a crack in the flare
nut after a long period, which may result in refrigerant leakage.
• For installation and relocation work, follow the instructions in the
Installation Manual and use tools and pipe components specifically
made for use with R32 refrigerant. If pipe components not designed
for R32 refrigerant are used and the unit is not installed correctly, the
pipes may burst and cause damage or injuries. In addition, water
leakage, electric shock, or fire may result.
• 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 qualified installer (*1) or qualified 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 unqualified individual
since failure to carry out the work properly may result in electric
shocks and/or electrical leaks.
• The appliance shall be installed in accordance with national wiring
regulations. Capacity shortages of the power circuit or an incomplete
installation may cause an electric shock or fire.
• Use wiring that meets the specifications in the Installation Manual and
the stipulations in the local regulations and laws. Use of wiring which
does not meet the specifications may give rise to electric shocks,
electrical leakage, smoking and/or a fire.
• Be sure to connect earth wire. (Grounding work) Incomplete earthing
causes an electric shock.
• Do not connect earth wires to gas pipes, water pipes, and lightning
rods or earth wires for telephone wires.
• After completing the repair or relocation work, check that the earth
wires are connected properly.
11-EN
• Install a circuit breaker that meets the specifications 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 must the power cable be extended.
Connection trouble in the places where the cable is extended may
give rise to smoking and/or a fire.
Test run
• Before operating the air conditioner after having completed the work,
check that the electrical parts 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, etc. if the power is
turned on without first conducting these checks.
• When you have noticed that some kind of trouble (such as when a
check display has appeared, there is a smell of burning, abnormal
sounds are heard, 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 qualified 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 qualified service person arrives.
Continuing to use the air conditioner in the troubled status may cause
mechanical problems to escalate or result in electric shocks, etc.
• After the work has finished, be sure to use an insulation tester set
(500V Megger) to check the resistance is 1 MΩ or more between the
charge section and the non-charge metal section (Earth section). If
the resistance value is low, an accident such as leak or electric shock
may occur.
