After completing repair, test the unit to ensure it runs properly. In addition, give the
user adequate instructions concerning the precautions when using this unit.
Warnings During Repair
Before dismantling the unit for repair, be sure to remove the power plug, as operating
a device that is powered on may result in electric shock. If repair must be carried out
with power on, do not touch any active part.
Keep away from the refrigerant gas that leaks during repair, because exposure to this
gas may result in frostbite.
When dismantling compressor intake or discharge pipes at welding part, first empty
refrigerant gas in a well-ventilated place, as the trapped refrigerant gas or refrigerator
oil may flow out and cause injuries.
If any refrigerant gas leaks during repair, ventilate the place immediately. Refrigerant
gas may produce a toxic gas if it comes in contact with fire.
Boost capacitor is a component that provides high voltage electricity for ODU
electrical parts. Make sure it is fully discharged before repair; otherwise, it may cause
electric shock.
Do not attempt to turn on or off the unit by inserting or removing the power plug, as
this may result in electric shock or fire.
Precautions During Repair
Do not attempt to touch electrical parts with wet hands, as it may cause electric shock.
Do not clean the air conditioner by spraying water on it, as it may cause electric
shock.
To prevent an electric shock, make sure that the unit is grounded when repair is
carried out in a damp place.
Cut off the power supply and remove the power plug before cleaning.
The fan running at high speed may hurt people.
When relocating the unit, do not tilt it; otherwise, the water inside the unit may splash
