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/Upflow Models:
•
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,” p. 12
).
•
Rigging the unit. Refer to
Figure 12, p. 19
.
•
Placing the unit on curb; check for levelness.
See “Roof
Curb and Ductwork” on page 13.
•
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. 21
.
•
Service Valve Option; See
“Starting the Compressor”
on page 76
.
•
Return/Fresh-air damper adjustment. Refer to
“Economizer Damper Adjustment” on page 74
.
•
Exhaust Fan Damper Stop Adjustment. Refer to
Exhaust Damper Adjustment figures, beginning with
Figure 51, p. 73
.
Electrical Requirements
(See
Figure 18, “Typical field power wiring,” on page 24
.)
•
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
(
Figure 19, p. 30
and
Figure 20, p. 31
.)
Important:
All field-installed wiring must comply with
NEC and applicable local codes.
•
Complete the field wiring connections for the constant
volume controls as applicable. Refer to the
“Low
Voltage Wiring” on page 28
for guidelines.
•
Complete the field wiring connections for the variable
air volume controls as applicable. Refer to the
“Low
Voltage Wiring” on page 28
for guidelines.
Gas Heat Requirements
(See
“Installation Piping” on page 36
.)
•
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.
•
Flue Tubes clear of any obstructions.
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 code could result in death or serious injury.
