Pre-Installation
Considerations
Skid Removal
The unit ships on skids to provide forklift
locations from the front or rear. The skid
allows easy maneuverability of the unit
during storage and transportation.
Remove the skids before placing the unit
in its permanent location.
Remove the skids using a forklift or jack.
Lift one end of the unit off of the skids.
See Figure I-PC-3 on page 11. Slide the
skids out and lower the unit at the
installation location. If using vibration
isolators for external isolation, refer to the
“Vibration Isolator Unit Option” section
on page 29.
Note: External isolation is not necessary
since units are internally isolated. Consult a
vibration specialist before externally
isolating the unit.
Pre-Installation Checklist
Complete the following checklist before
beginning unit installation.
o
Verify the unit size and tagging with the
unit nameplate.
o
Make certain the floor or foundation is
level, solid, and sufficient to support the
unit and accessory weights. See Table
I-DW-1
on page 13. Level or repair the
floor before positioning the unit if
neccesary.
o
Allow minimum recommended
clearances for routine maintenance and
service. Refer to unit submittals for
dimensions.
o
Allow three fan diameters above the
unit for the discharge ductwork. Return
air enters the rear of the unit and
conditioned supply air discharges
through the top.
o
Electrical connection knockouts are on
the top, left side of the unit.
o
Allow adequate space for piping
access and panel removal. Condenser
water piping, refrigerant piping, and
condensate drain connections are on
the lower left end panel.
Note: Unit height and connection locations
will change if using vibration isolators. The
unit height may increase up to 5
7
/
8
” with
spring type isolators.
o
Electrical supply power must meet
specific balance and voltage
requirements as described in the
“Electrical Requirements” section on
page 26.
o
Water-cooled units only: The installer
is responsible for providing a condenser
main, standby water pump, cooling
tower, pressure gauges, strainers, and
all components for waterside piping.
See the “Water Piping” section on page
23 for general waterside
recommendations.
o
Air-cooled units only: The installer is
responsible for providing and installing
the remote air-cooled condenser and
refrigerant piping, including filter driers.
