Installation Checklist

General Checklist (Applies to all units)
The checklist listed below is a summary of the steps
required to successfully install a Commercial rooftop
unit. This checklist is intended to acquaint the installing
personnel with what is required in the installation
process. It does not replace the detailed instructions
called out in the applicable sections of this manual.
I I m m p p o o r r t t a a n n t t : : This checklist does not replace the detailed
instructions called out in the applicable
sections of this manual.
☐ Unit checked for shipping damage and material
shortage.
☐ Verify that the installation location of the unit will
provide the required clearance for proper
operation.
☐ Roof curb assembled and installed.
☐ Roof curb level and square.
☐ Ductwork secured to curb, or unit.
☐ Corners of duct adapters sealed on units with
horizontal supply or return.
☐ Horizontal supply or return ductwork is self
supporting.
☐ Pitch pocket installed for units with power supply
through building roof.
☐ Unit set on curb and checked level.
☐ Unit-to-curb seal checked to ensure it is tight and
without buckles or cracks.
☐ Condensate drain lines installed to each evaporator
drain connection.
☐ Verify that all access doors open 100% and are not
obstructed by drain lines etc.

☐ Shipping hardware removed from each compressor
assembly.
☐ Shipping hold-down bolts and shipping channels
removed from the supply and exhaust/return fans
with spring isolators.
☐ Supply and exhaust/return fans spring isolators
checked for proper adjustment.
☐ Plastic coverings (paint shields) removed from all
compressors (if present).
☐ Verify all discharge and suction line service valves
are back seated.
☐ Compressor crankcase heaters energized for a
minimum of 12 hours prior to unit refrigeration
system start-up.
☐ Verify that unit literature (IOM, PTG) are left inside
control box for start-up.
Unit Rigging and Placement (Two-piece
—addition to General Checklist)
☐ First, rig and set the low side unit on the roof curb
(aligned with return end).
☐ Remove the rail connector splice brackets and
install the brackets on the low side unit base rails.
☐ Take off the side panels (these are labeled) and the
top cover of the high side unit and set aside to be
assembled later.
☐ Rig and set the high side unit on roof curb pedestal.
☐ Lift the unit and position it over the pedestal.
☐ Use the rail splice bracket as an alignment aid to
connect the Low and high side units. The Low and
high side unit rails should be butted together with a
maximum 2" (preferably 1") separation.
☐ Remove the left upper and lower louvered panels of
the high side unit as well as the corner panels on
each side to aid in tubing and wiring connections.
☐ Close refrigeration shut off valves as indicated in
this manual—Liquid, discharge, hot gas bypass (if
present), and hot gas reheat (if present).
☐ For Evaporative Condensers: Recover/transfer
charge from tubing between shut valves and stub
point.
☐ For 2 and 3 piece Air-Cooled condensers add field
charge per nameplate.
☐ Braze refrigerant piping connections and leak test.
☐ Low side and high side evacuated to 500 microns.
☐ Standing vacuum does not rise over 200 microns in
15 minutes.
☐ Open service valves to allow refrigerant flow.
☐ Refrigerant released from discharge to suction until
suction pressure is approximately 60 PSIG.
☐ Power wires connected in connection box.
☐ Control wires connected in connection box.
