•
When installing or relocating the air conditioner, be sure to bleed the refrigerant circuit to ensure it is free of air,and use only the
specified
refrigerant (R32). The presence of air or other foreign matter in the refrigerant circuit causes abnormal pressure rise,
which may result in
equipment damage and even injury.
•
During installation, attach the refrigerant piping securely before running the compressor. If the refrigerant pipes are not attached
and the stop
valve is open when the compressor is run, air will be sucked in, causing abnormal pressure in the refrigeration cycle,
which may result in
equipment damage and even injury.
•
During pump-down, stop the compressor before removing the refrigerant piping.
If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping
is removed,
causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury.
•
Be sure to earth the air conditioner.
Do not earth the unit to a utility pipe, lightning conductor or telephone lead. Imperfect earthing may result in electric shocks.
•
Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks or fire.
•
During tests, never pressurize the appliances with a pressure higher than the maximum allowable pressure (as indicated on the
nameplate
of the unit).
•
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to
avoid
a hazard.
•
After completing installation, check for refrigerant gas leakage. T oxic gas may be produced if the refrigerant gas leaks into
the room and
comes into contact with a source of fire, such as a fan heater, stove or cooker.
CAUTION
•
Do not install the air conditioner at any place where there is a danger of flammable gas leakage.
In the event of a gas leakage, build-up of gas near the air conditioner may cause a fire to break out.
•
While following the instructions in this installation manual, install drain piping to ensure proper drainage a nd insulate piping to
prevent
condensation. Improper drain piping may result in indoor water leakage and property damage.
•
Tighten the flare nut according to the specified method such as with a torque wrench.
If the flare nut is too tight, it may crack after prolonged use, causing refrigerant leakage.
•
Make sure to provide for adequate measures in order to p
r
e
vent that the outdoor unit be used as a shelter by small animals.
Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep
the area around the unit clean.
•
The temperature of refrigerant circuit will be high, please keep the
connecting pipework correctly insulated to avoid injury.
