 WARNING

Do not touch the fins. Otherwise, personal injury could result.

 CAUTION

When carrying the unit, hold the handles on the right and left sides and be careful.
If the outdoor unit is carried from the bottom, hands or fingers may be pinched.

Hoisting method

• When hoisting the outdoor unit, hook the rope on the outside of the foot as shown in the 

figure.

• Use sufficiently strong rope to bear the unit’s weight.
• Place protective board or filler cloth at the place where the cabinet may come into 

contact with the rope to prevent damages. Without using them, the cabinet may be dam-
aged or deformed.

• The center of gravity of the outdoor unit is shifted to the right. Be careful not to tilt to the 

heavy side causing it to fall.

• To prevent an accident caused by the unit swinging or falling down, do not apply any 

impact to the unit when it is hanging.

• When hoisting, do not hook the rope to the thermistor holder on the back of the outdoor 

unit.
