<I. Precautions for Construction and Repair>
WARNING
(1) To overhaul the equipment,
be sure to turn OFF all power
supplies.
(2) If a refrigerant gas belches
during work, do not touch the
refrigerant gas.
Not doing so will result in an electric
shock.
To repair the equipment or check for
circuits with power applied, pay utmost
attention not to touch any live part.
Doing so will result in
frostbite.
(3) To remove a welded part
from the suction or discharge
pipe of compressor, remove
it in a well-ventilated area
after thoroughly discharging
a refrigerant gas.
Not doing so will cause the refrigerant
gas or refrigerant oil to belch, thus
resulting in injury.
(4) If a refrigerant gas leaks
during work, ventilate the
working area.
If the refrigerant gas comes
into contact with a flame,
toxic gas will be generated.
(5) The electrical parts of
outdoor unit carry a high
voltage.
To repair these
parts, thoroughly
discharge
electricity from the
capacitor.
Not doing so will result in an electric
shock.
