Pre-Startup Checklist
Complete this checklist after installing the
unit to verify all recommended
installation procedures are complete
before unit startup. This does not replace
the detailed instructions in the
appropriate sections of this manual.
Disconnect electrical power before
performing this checklist. Always read the
entire section carefully to become
familiar with the procedures.
WARNING
Hazardous Voltage w/Capacitors!
Disconnect all electric power,
including remote disconnects and
discharge all motor start/run
capacitors before servicing. Follow
proper lockout/tagout procedures to
ensure the power cannot be
inadvertently energized. Verify with an
appropriate voltmeter that all
capacitors have discharged. Failure to
disconnect power and discharge
capacitors before servicing could
result in death or serious injury.

requirements
Receiving
Inspect unit and components for
shipping damage. File damage claims
immediately with the delivering
carrier.
Check unit for missing material. Look
for ship-with options and sensors that
may be packaged separately from
the main unit. See the “Receiving and
Handling” section.
Check nameplate unit data so that it
matches the sales order
requirements.
Unit Location
Remove the shipping skid when the
unit is set in its final position.
Ensure the unit location is adequate
for unit dimensions, ductwork, piping,
and electrical connections.
Ensure access and maintenance
clearances around the unit are
adequate.
Unit Mounting
Place unit in its final location.
Remove shipping skid bolts and skid.
Properly install any field-provided
isolators per instructions in
Figures I-IP-1 and I-IP-2 .
Component Overview
Inspect fan belt tension and sheave
alignment. Refer to Figure M-MP-1.
Inspect the fan motor and bearing
lubrication.
Check the bearing locking collar and
sheave set screw for proper torque
settings. Refer to the Appendix.
Ensure the fan rotates freely in the
correct direction.
Verify that a clean air filter is in place.
Installation
Ductwork
If using return ductwork to the unit,
secure it with three inches of flexible
duct connector.
Extend discharge duct upward
without change in size or direction for
at least one and one half fan
diameters.
Use a flexible duct connection on
discharge and inlet ductwork.
Ensure trunk ductwork is complete
and secure to prevent leaks.
Verify that all ductwork conforms to
NFPA 90A or 90B and all applicable
local codes.
Unit Piping
Verify the condensate drain piping is
complete for the unit drain pan.
Make return and supply water
connections to the unit and/or piping
package.
Ensure the drain pan and condensate
line are not obstructed. Remove any
foreign matter that may have fallen
into the drain pan during installation.
Verify that piping does not leak. Drain
lines should be open while
performing this test.
Treat water to prevent algae, slime,
and corrosion.
Electrical
Check all electrical connections for
tightness.
Unit Panels
Ensure all unit access panels are in
place and that all screws, nuts, and
bolts are tightened to their proper
torques.
