12. HOW TO REPLACE THE MAIN PARTS
WARNING
When handling the electric parts, be sure to turn off the power supply breaker because high
voltage is electrified.
If failing to pull out the power supply plug or to turn off the breaker, an electric shock may be caused.
After repairs, carry out a trial operation and check there is no trouble such as smoke or abnor-
mal sound.
Otherwise, a fire or electric shock may be caused.
Cautions on repairs for refrigeration cycle
(1) Be careful to fire near by. If using a gas stove, etc., be sure to turn off the switch. If failing to do so, the oil
mixed with refrigerant gas may catch fire.
(2) Do not use a welding machine in the closed room. If ventilation is failed, poisoning of carbon monoxide
may be caused.
(3) Do not lay flammables. The fire of the welding machine may catch the flammables.
