proper system subcooling and superheat will be verified.
The unit fans will be checked to ensure that the condenser
fan blade set-screws to the motor shaft are tight, that the
hold down bolts and channels from fan sections have been
removed, proper adjustment of fan section spring isolators,
proper fan belts tension, adequate fan bearings grease,
alignment of fan sheaves, adequate tightness of supply
and exhaust fan pulley bolts, proper fan rotation, and
proper fan motor amperage.
A check will be made to ensure both piping to the
condenser and air handler side of the system have been
completed and interconnecting refrigerant tubing has been
evacuated by the contractor prior to Trane performing the
start-up. All damper linkages will be checked for proper
adjustment, and proper damper operation and outside air
pressure sensors verified.
Units equipped with electric heaters will be checked to
ensure that the heating system matches the unit nameplate
and for correct voltage supply to the heaters. Units
equipped with gas heaters will be checked to ensure that
the flue assembly is secure and properly installed,
sufficient gas pressure exists according to pipe size, no
leaks exist in gas supply line, the gas heat piping includes
a drip leg, condensate line and the combustion air CO

levels are normal. Units equipped with hot water heat
will be checked to ensure that the hot water pipes are
properly routed, sized and leak free; for the presence of
swing joints or flexible connectors next to the hot water coil;
proper gate valve installation in the supply and return
branch line; proper three way modulating valve installation,
and proper coil venting will be verified.
Units equipped with steam heat will be checked to ensure
that the hot water pipes are properly routed, sized and leak
free; proper swing check vacuum breaker installation;
proper 2-way modulating valve installation; proper steam
trap installation. Units equipped with energy recovery
wheels will be checked to ensure proper rotation and
operation of the wheel. The service test guide will be used
to check proper component operation. Finally, the program
set points for proper unit operation will be validated through
human interface module. Once the IntelliPak 2 multi-piece
unit has been started, a communication will be provided of
start-up activities and the associated operating log.
