Final Unit Checkout
After completing all of the checkout and start-up
procedures outlined in the previous sections (i.e., operating
the unit in each of its Modes through all available stages of
cooling and heating), perform these final checks before
leaving the unit:
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.
Important: HIGH VOLTAGE IS PRESENT AT TERMINAL
BLOCK OR UNIT DISCONNECT SWITCH.
☐ Close the disconnect switch or circuit protector switch
that provides the supply power to the unit terminal block
or the unit mounted disconnect switch.
☐ Turn the 115 volt control circuit switch Off.
☐ Turn the 24 volt control circuit switch to the On position.
☐ Press the SETUP key. The LCD screen will display
various preset “parameters of operation” based on the
unit type, size, and the installed options. Compare the
factory preset information to the specified application
requirements. If adjustments are required, follow the
step-by-step instructions provided in the appropriate
programming manual for VAV applications.
☐ Program the Night Setback (NSB) panel (if applicable)
for proper unoccupied operation. Refer to the
programming instructions for the specific panel.
☐ Verify that the Remote panel “System” selection switch,
“Fan” selection switch, and “Zone Temperature”
settings for constant volume systems are correct.
☐ Verify that the Remote panel “System” selection switch
and the “Supply Air Temperature” settings for variable
air volume systems are correct.
☐ Inspect the unit for misplaced tools, hardware, and
debris.
☐ Turn the 115 volt control circuit switch On.
☐ Press the AUTO key to begin system operation. The
system will start automatically once the dampers
modulate and a request for either heating or cooling
has been given.
☐ Verify that all exterior panels including the control panel
doors and condenser grilles are secured in place.
Multi-piece Unit – Trane Start-Up
When the following are complete, Trane will provide unit
start-up:
☐ IntelliPak 2 multi-piece unit has been installed.
☐ All shipped with items have been installed.
☐ All utilities and drain pipes have been connected.
☐ All refrigeration piping has been reconnected and
refrigerant charge has been adequately distributed
throughout the system.
☐ All ductwork has been attached to the unit.
Trane start-up of multi-piece units will review the overall
unit for exterior damage (dents, bends, missing panels,
doors work properly), verify that the unit interior is free from
debris/obstructions, ensure that the panels and doors are
secured properly and verify that all wiring connections are
tight. The overall installation will be reviewed to ensure the
unit clearances are adequate to avoid air recirculation and
all unit drain lines and traps are properly installed.
The unit main power will be reviewed to ensure the unit is
properly grounded, the main power feed wire gauge is
adequately sized, the correct voltage is supplied to unit and
electric heaters, and the incoming voltage is phase
balanced. Verification will be performed to ensure that all
field installed control wiring is applied to the correct
terminals, all automation and remote controls installed/
wired and control wiring for SZVAV and VAV controls is
completed.
The refrigeration system will be reviewed to ensure the coil
fins are straightened, the removal of shipping hardware
and plastic covers for compressors, proper oil level in the
compressors, crankcase heaters have been operational for
at least 12 hours time prior to Trane start-up being
performed. The proper compressor voltage and amperage,
correct position of service valves prior to start-up and
