Step 4 — Rig and Place Unit —
Use spreader bars
or crate top when rigging the unit. The units must be rigged
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
condensate drainage; the ground-level pad or accessory roof
curb must be level before setting the unit in place. When a
field-fabricated support is used, be sure that the support is
level and that it properly supports the unit.
UNITS WITHOUT BASE RAILS — Accessory rigging brack-
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.
Install accessory rigging brackets as follows:
1. Position brackets as close to the corners of unit as pos-
sible. Be sure brackets are well outside of center of grav-
ity. (See Fig. 2, 4, and 8.)
2. Position paint protectors and foam strips between screws
and painted surface of unit. Tighten screws until they make
contact with the paint protectors.
3. Secure device or hook of sufficient strength to hole in bracket
as shown in detail ‘‘A’’ of Fig. 8.
4. If wood top is available, use it for a spreader bar to pre-
vent straps from damaging unit. If wood top is not avail-
able, use spreader bars of sufficient length.
UNITS WITH OPTIONAL BASE RAILS — Keep unit up-
right and do not drop. Use spreader bars or top crate when
rigging unit. Rollers may be used to move unit across roof.
The unit must be level for proper condensate disposal. Rig
unit as shown in Fig. 9. See Fig. 3 and 5 for additional in-
formation. Lifting holes are provided in base rails as shown
in Fig. 9. Refer to rigging instructions on unit.
NOTICE TO RIGGERS
Hook rigging shackles through holes in lifting brackets, as shown in
detail ‘‘A.’’ Lifting brackets to be centered around the unit center of
gravity. Use wood top skid when rigging, to prevent rigging straps
from damaging unit.
All panels MUST be in place when rigging.
