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-
tailed instructions called out in the ap-
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 vertical units have been
tied to the skid by (8) shipping
brackets with (16) 5/16" screws.
Remove the (8) screws attached on
the unit side, and (2) screws at-
tached at the L bracket side. The
unit may now be slid off of the
skid. Re-attach (8) of the screws
into the unit base pan.
2 Verify the correct model, options
and voltage from the unit name-
plate.
3 Verify the installation location of
the unit will provide the required
clearance for proper operation.
4 Remove refrigeration access panel
and inspect the unit. Be certain the
refrigerant tubing has clearance
from adjacent parts.
