Pre-Installation
The checklist listed below is a summary of the steps
required to successfully install a Voyager 3 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/Upflow Models
• An optional roof curb, specifically designed for the
Voyager 3 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 “General Information,” p. 10).
• Rigging the unit. Refer to Figure 16, p. 18.
• Placing the unit on curb; check for levelness.
• 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 18, p. 23.
• Service Valve Option; See “Starting the
Compressor,” p. 58.
• Return/Fresh-air damper adjustment. Refer to
“Economizer (O/A) Dampers,” p. 51.
• Exhaust Fan Damper Stop Adjustment. Refer to
Exhaust Damper Adjustment figures, beginning with
Figure 37, p. 50.
Electrical Requirements
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
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/national
electrical codes.
• 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.
• Properly ground the unit.
Field Installed Control Wiring
Refer to and .
Complete the field wiring connections for the constant
volume and variable air volume controls as applicable.
Refer to “Low Voltage Wiring,” p. 29.
Important: All field-installed wiring must comply with NEC
and applicable local codes.
Gas Heat Requirements
Refer to “Installation Piping,” p. 33.
• Gas supply line properly sized and connected to the
unit gas train.
• All gas piping joints properly sealed.
• Drip leg Installed in the gas piping near the unit.
• Gas piping leak checked with a soap solution. If piping
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.
• Gas heat exhaust clear of any obstructions.
