Evaporator Assembly
The lifting chains along the axis of the
evaporator shell should not exceed 90°
+/- 10°. A spreader bar may be required
to achieve the +/- 10°.
One chain is required per each lifting
point.
Use lifting chains with working load limit
each at least 40% of the total shell and
installed component weight.
1. Attach rigging chains to an adequate lifting device.
2. Attach chains to the lifting holes at the corner of
the end sheets as shown in Figure 19 on page 28.
3. If necessary to maintain minimum angles install
side spreader bars between the evaporator end
sheets to have the chains at 90° as shown in Fig-
ure 19 on page 28.
The angle of the lifting chains is critical
and damage to the unit may occur if the
rigging is not completed as described.
4. With an adequate lifting device lift the unit slight-
ly off the ground to check for center of gravity.
Make adjustments as necessary to level the unit.
