CAUTIONS for SAFETY

WARNING

• Ask an authorized dealer or qualified installation professional to install/maintain the air conditioner.

Inappropriate installation may result in water leakage, electric shock or fire.

• Turn off the main power supply switch or breaker before attempting any electrical work.

Make sure all power switches are off. Failure to do so may cause electric shock.

• Connect the connecting cable correctly.

If the connecting cable is connected in a wrong way, electric parts may be damaged.

• When moving the air conditioner for the installation into another place, be very careful not to enter any gaseous

matter other than the specified refrigerant into the refrigeration cycle.

If air or any other gas is mixed in the refrigerant, the gas pressure in the refrigeration cycle becomes abnormally high and

it may resultingly causes pipe burst and injuries on persons.

• Do not modify this unit by removing any of the safety guards or by by-passing any of the safety interlock switches.

• Exposure of unit to water or other moisture before installation may cause a short-circuit of electrical parts.
