+/- 10° from horizontal. A spreader bar
may be required to achieve the +/- 10°.
1. Attach rigging chains to an adequate lifting device.
2. Attach chains to the lifting holes at the corner of
each end sheet as shown on Figure 2 on page 16.
3. If necessary to avoid contact with chiller compo-
nents install side spreader bars between the Evap-
orator and Condenser end sheet lifting chains.
4. The angle of the lifting chains traversing the en
sheet should not be less than 65° as shown on Fig-
ure 2 on page 16.
5. With an adequate lifting device lift the unit slight-
ly off the ground to determine adjustments neces-
sary to keep the unit level. Make adjustments as
