The checklist below is a summary of
the steps required to successfully in-
stall a unit. This checklist is intended to
acquaint the installing personnel with
procedures required in the installation
process. It does not replace the de-

plicable sections of this manual.
1 Remove packaging and inspect the
unit. Check the unit for shipping
damage and material shortage; file
a freight claim and notify appropri-
ate sales representation.

the skid by (4) angle brackets. Re-
move these brackets from the unit

the unit will provide the required

refrigerant tubing has clearance
from adjacent parts.
