for lifting as shown in Fig. 8 and 9. Refer to Fig. 8 and 9 and
Table 1 for rigging weights. See Fig. 2-5 for operating weights.
Use extreme caution to prevent damage when moving the
unit. Unit must remain in an upright position during all rig-
ging and moving operations. The unit must be level for proper

level and that it properly supports the unit.

ets are recommended to be used for rigging.
Secure screws and paint protectors solidly against unit
basepan to hold lifting brackets in position.
Never use lifting brackets when the temperature is
below −10 F.
Never exceed 200 lbs per bracket of lifting force.
Never use lifting brackets for lifting other models of air
conditioning units.
Lifting point should be directly over the unit center of
gravity.
