1. Thread the swivel adapters into the female pipe
thread fittings projecting through the top of the
compressor compartment access cover. To prevent
twisting of the copper water piping in the chassis
assembly, always use a backup wrench.
To minimize the possibility of damage to
the chassis or cabinet and for maximum
ease of installation, the use of a two-
wheeled dolly is strongly recommended.
Do not contact the finned coil face. Dam-
age to the fins will result.
2. Lift chassis from the front of chassis (see Figure
22 on page 33).
3. Align chassis with the opening of the cabinet. Tilt
the chassis sufficiently for the base of the chassis
to clear the mounting rails on the cabinet drain
pan (see Figure 23 on page 33).
4. Insert the chassis midway into the opening of the
cabinet. Lower the rear of the chassis until the
base of the chassis touches the formed mounting
rails in the cabinet drain pan (see Figure 24 on
page 33).

5. Pivot the chassis base on the front edge of the
drain pan rails. Before fully inserting the chassis,
ensure the wiring harness and water hoses cannot
be pinched between the chassis and cabinet (see
Figure 25 on page 34).
