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!
Before servicing unit disconnect all
electrical power including remote
disconnects. Follow proper lockout/
tagout procedures to ensure power
cannot be inadvertently energized.
Failure to disconnect power before
servicing can cause death or serious
injury.
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 drives, isolators, filters,
and sensors that are packaged
separately and placed inside the main
control panel, fan section, or
compressor section. See the
“Receiving and Handling” section on
page 7.
!
Check nameplate unit data so that it
matches the sales order requirements.
Pre-Startup
Requirements
Unit Location
!
Remove crating from the unit. Do not
remove the shipping skid until 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. Allow space at the end of the
unit for shaft removal and servicing.
See the “Service Access” section on
page 7.
Unit Mounting
!
Place unit in its final location.
!
Remove shipping skid bolts and skid.
"
If using isolators, properly mount unit
according to the isolator placement
sheet.
Component Overview
!
Verify the fan and motor shafts are
parallel.
!
Verify the fan and motor sheaves are
aligned.
!
Check the belt tension for proper
adjustment. Adjust the belt tension if it is
floppy or squeals continually.
!
Ensure the fan rotates freely in the
correct direction.
!
Tighten locking screws, bearing set
screws and sheaves.
!
Ensure bearing locking collars do not
wobble when rotated and correct
torque settings. Refer to Table M-MP-1
on page 43 for recommended torques.
!
Verify that a clean air filter is in place.
Ductwork
!
If using return ductwork to the unit,
secure it with three inches of flexible
duct connector.
Installation
!
Extend discharge duct upward without
change in size or direction for at least
one and one half fan diameters.
!
Use a 3” flexible duct connection on
discharge 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. Install
and tighten the condensate “P” trap
drain plug.
!
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. Make
sure drain lines are open while
performing the leak test.
"
Treat water to prevent algae, slime,
and corrosion.
"
Connect refrigerant piping lines.
Electrical
"
Check all electrical connections for
tightness.
"
Verify motor voltage and amps on all
phases with the unit nameplate ratings
to ensure unit operates correctly.
Unit Panels
"
Ensure all unit access panels are in
place and that all screws, nuts, and bolts
are tightened to their proper torques.
Note: During the unit break-in period,
bearing temperature may be 150–160°F.
during normal operation bearing tem-
perature should range be 90–100°F.
