Pre-Installation
The checklist listed below is a summary of the steps required to successfully install a Voyager
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.
General Unit Requirements
Downflow Models Only:
• An optional roof curb, specifically designed for the Voyager commercial rooftop units is
available from Trane. The roof curb kit must be field assembled and installed according to the
latest edition of the curb installation guide.
• Assemble and install the roof curb, including necessary gaskets. Make sure the curb is level.
• Install and secure the ductwork to the curb.
All Units:
• Check unit for shipping damage and material shortage. (Refer to "Unit inspection" section).
• Rigging the unit. Refer to Figure 12, p. 24.
• Placing the unit on curb; check for levelness. See “Roof Curb and Ductwork” on page 16.
• Ensure that the unit-to-curb seal is tight and without buckles or cracks.
• Install an appropriate drain line to the evaporator condensate drain connections, as required.
Refer to Figure 14, p. 29.
• Service Valve Option; See “Starting the Compressor” on page 98.
• Return/Fresh-air damper adjustment. Refer to “Economizer Damper Adjustment” on page 94.
• Exhaust Fan Damper Stop Adjustment. Refer to Exhaust Damper Adjustment figures,
beginning with Figure 46, p. 103.
Electrical Requirements
(See Figure 18, “Typical Field Power Wiring,” on page 34.)
• Verify that the electrical power supply characteristics comply with the unit nameplate
specifications.
• Inspect all control panel components; tighten any loose connections.
• Connect properly sized and protected power supply wiring to a field supplied/installed
disconnect and unit power terminal block HTB1, or to the optional unit-mounted disconnect
switch.
WARNING
Proper Field Wiring and Grounding Required!
All field wiring MUST be performed by qualified personnel. Improperly installed and grounded
field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards, you MUST follow
requirements for field wiring installation and grounding as described in NEC and your local/
state electrical codes. Failure to follow codes could result in death or serious injury.
• Properly ground the unit.
