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.
