SECTION 3 - INSTALLATION
Level The Unit
The longitudinal alignment of the unit should be
checked by placing a level on the top center of the
evaporator shell under the compressor/motor assem-
bly. Transverse alignment should be checked by plac-
ing a level on top of the shell end sheets.
The unit should be level within 1/4" (6 mm) from one
end to the other end and from front to the rear. If the
chiller is not level within the amount specified, lift
it and place shims between the isolation pad and the
chiller tube sheets. (Shims are furnished by the install-
er.) Lower unit again and recheck to see that it is level.
Checking The Isolation Pad Deection
All isolation pads should be checked for the proper de-
flection while checking to see if the unit is level. Each
pad should be deflected approximately 0.10 inches
(2.5 mm) to 0.20 inches (5 mm). If an isolation pad is
under-deflected, shims should be placed between the
unit tube sheet and the top of the pad to equally deflect
all pads.
