General Installation Checks
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.
Note: The units have been tied to
the skid by (4) angle brackets. Re-
move these brackets from the unit

2 Verify the correct model, options
and voltage from the unit name-

3 Verify the installation location of
the unit will provide the required
clearance for proper operation.

and inspect the unit. Be certain the
refrigerant tubing has clearance
from adjacent parts.
