[ ] Check the unit for shipping damage and material short-

age; file a freight claim and notify Trane office.

[ ] Verify that the installation location of the unit will provide

the required clearance for proper operation.

[ ] Assemble and install the roof curb. Refer to the current

edition of SAHF-IN-5 for 20 through 75 Ton units or
SXHG-IN-2 for 90 through 130 Ton units.

[ ] Fabricate and install ductwork; secure ductwork to curb.

[ ] Install pitch pocket for power supply through building

roof. (If applicable)

[ ] Rigging the unit.

[ ] Set the unit onto the curb; check for levelness.

[ ] Ensure unit-to-curb seal is tight and without buckles or

cracks.

[ ] Install and connect condensate drain lines to each

evaporator drain connection.

[ ] Remove the shipping hardware from each compressor

assembly.

[ ] Remove the shipping hold-down bolts and shipping chan-

nels from the supply and exhaust fans ordered with rub-
ber or spring isolators.

[ ] Check all optional supply and exhaust fan spring isola-

tors for proper adjustment.

[ ] Verify that all plastic coverings are removed from the

compressors.

[ ] Verify all discharge and liquid line service valves (one per

circuit) are back seated.

Main Electrical Power Requirements

[ ] Verify that the power supply complies with the unit name-

plate specifications.

[ ] Inspect all control panel components; tighten any loose

connections.

[ ] Connect properly sized and protected power supply wir-

ing to a field-supplied/installed disconnect and unit

[ ] Properly ground the unit.

Note: All field-installed wiring must comply with
NEC and applicable local codes.

volume controls as applicable. Refer to "Field Installed
Control Wiring" for guidelines.

[ ] Complete the field wiring connections for the variable air

volume controls as applicable. Refer to "Field Installed
Control Wiring" for guidelines.

Note: All field-installed wiring must comply with
NEC and applicable local codes.

Requirements for Electric Heat Units

connections to the unit are complete, do not pressurize
piping in excess of 0.50 psig or 14 inches w.c. to prevent
component failure.

[ ] Main supply gas pressure adequate.

[ ] Flue Tubes clear of any obstructions.

[ ] Factory-supplied flue assembly installed on the unit.

[ ] Connect the 3/4" CPVC furnace drain stubout to a proper

condensate drain.
