Transportation and Installation
Lift the unit by placing the slings at desig-
nated locations. Support the outdoor unit
securely at four points to keep it from slip-
ping and sliding. If the unit is not properly
supported, it may fall and cause personal
injury.

or falling over, periodically check the instal-
lation base for damage.

disposal of the unit. Refrigerant oil and re-
frigerant that may be left in the unit pose a

lution.

heat exchanger fins or sharp edges of com-
ponents with bare hands.
Always wear protective gears when touch-
ing electrical components on the unit. Sev-
eral minutes after the power is switched off,
residual voltage may still cause electric
shock.
To reduce the risk of electric shock and
burns, always wear protective gear when
working on units.
To reduce the risk of injury, do not insert fin-
gers or foreign objects into air inlet/outlet
grills. If the unit is left on a damaged base, it
may fall and cause injury.
