Lifting Points
Refer to Figure 28 and Figure 29
to determine whether a four or six point lift is required.
X = distance from the entering air end of the unit (or shipping
section) to the first lifting lug in the direction of air flow.
For all unit or shipping sections with outdoor air/return air
options, X = 48ʺ
For shippings sections without outdoor air/return air
options, X= 0
Y = distance from condenser or leaving air end of unit to the
last lifting lug.
For all units or shipping sections with condensers use the
following:
Unit Size
015, 020, 025
030, 035, 040
016, 021, 026, 031, 042,
050, 062, 068
051, 063, 070, 071, 075, 079,
080, 085, 090, 100, 105
081, 091, 101, 110-140
For all units or shipping sections without condensers, Y = 0.
Installation
Z = total base rail length of the units.
NOTE: Z excludes hoods and overhung parts extending past
base rails of the unit.
A = Z - X - Y
If A < 288ʺ, 4-point lift is sufficient
If A > 288ʺ, 6-point lift is required
B = distance from first lifting lug to middle lifting lug on units
with 6-point lift.
B = A / 2 +/- 48ʺ
NOTE: Middle lifting lug may be installed on either side of the
midpoint to avoid interference with condensate drains.
