Added bullwrap to electrical wiring between
evaporator and outside air section
Connected power and control wiring between
evaporator and outside air section
Gasket applied and side panels installed on unit split
Butyl tape applied on top of unit split along roof seam
and roof cap installed
Field Installed Control Wiring—Complete the field
wiring connections for constant volume or variable air
volume controls as applicable. Refer to “Field Installed
Control Wiring” for guidelines
Electric Heat Units
Inspect the heater junction box and control panel;
tighten any loose connections
Check electric heat circuits for continuity
Two andThree piece units only) Route power wiring to
high side junction box
Gas Heat Units
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" W.C. to prevent
component failure
Main supply gas pressure between 7" and 14" W.C.
Flue Tubes clear of any obstructions
Factory-supplied flue assembly installed on the unit
Connect the 3/4" CPVC furnace drain stub-out to a
proper condensate drain
Install field provided heat tape to furnace drain line
Hot Water Heat
Route properly sized water piping through the base of
the unit into the heating section
Install the factory-supplied, 3-way modulating valve
Complete the valve actuator wiring
Steam Heat
Route properly sized steam piping through the base of
the unit into the heating section
Install the factory-supplied, 2-way modulating valve
Complete the valve actuator wiring
Install 1/2", 15-degree swing check vacuum breaker(s)
at the top of each coil section. Vent breaker(s) to the
atmosphere or merge with return main at discharge side of
steam trap
Position the steam trap discharge at least 12" below the
outlet connection on the coil
Use float and thermostatic traps in the system, as
required by the application.
O/A Pressure Sensor and Tubing Installation (All VAV
units and CV units with return fan or StatiTrac)
O/A pressure sensor mounted to the roof bracket
Factory supplied pneumatic tubing installed between
the O/A pressure sensor and the connector on the vertical
support
(Units with StatiTrac) Field supplied pneumatic tubing
connected to the proper fitting on the space pressure
transducer located in the filter section, and the other end
routed to a suitable sensing location within the controlled
space
Electrical
Verify that the power supply to the unit complies with
the unit nameplate specification
Properly ground the unit
Inspect all control panel components and tighten any
loose connections
Connect properly sized and protected power supply
wiring to a field supplied/installed disconnect and the unit
(copper wiring only to the unit)
Verify that phasing to the unit is correct (ABC)
Turn the 1S2 toggle switch off to prevent accidental unit
operation
Turn on power to the unit
Press the STOP button on the Human Interface (1U2)
Verify that all compressor crankcase heaters are
energized for at least 12 hours prior to unit startup
Evaporative Condenser
Remove fan bracket
Hookup inlet and drain piping
Install Heat tape if needed
Setup drain hold or drain on power loss
Setup Mechanical Float
Setup drain time
Setup water quality management (3rd party or Trane
factory-installed Dolphin Water Care System)
Options setup
Calibrate Conductivity Controller
Setup blowdown set points on the conductivity
sensor
