Complete Tubing and Wiring Connections
as follows:
Air-Cooled Tubing Connection
One piece Air Cooled units are shipped with refrigerant
throughout the entire tubing assemblies.
Two and three piece Air-Cooled low side and condenser sections are shipped with a Nitrogen holding charge. All
service valves are shipped in an open position. Additional
interconnecting tubes (approx. 15-20” in length) will be
supplied with the unit.
Note: Field charging of 2 and 3 piece air-cooled...

If the rise exceeds this, there is either still moisture in
the system or a leak is present.
10. Charge the system per the unit nameplate field c
 harge.Do not add refrigerant in the suction line at this
time to prevent excessive refrigerant in the low side
prior to compressor startup.
11. At the liquid line angle valve add as much R-410A LIQ
 UID as possible. Depending on conditions, it could
not be possible to add more than 60% of the field
charge. This will be adequate for...

Electric Heat Wiring Connection
Important:For units with electric heat, complete tubing
connections AFTER completing wiring
connections. See “Tubing Connections”
section.
1. Cut and remove wire ties which hold the electric control wires together, remove the shield bracket.
Leave the armaflex on the hole with the control wires.
2. Cut the lowest wire tie which holds the electric heatpower wires to the vertical post on the high side.
3. Route the power wires one by one in to the...

General Unit Requirements
The checklist below is a summary of the steps required to
successfully install a 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.
[ ] Check the unit for shipping damage and material
shortage; file a freight claim and notify Trane office.
[ ] Verify that the...

Rigging the Unit
[ ] Set the unit onto the curb; check for levelness.
[ ] Ensure unit-to-curb seal is tight and without buckles
or cracks.
[ ] Install and connect condensate drain lines to each
evaporator drain connection.
[ ] Remove the shipping hardware from each
compressor assembly.
[ ] Remove the shipping hold-down bolts and shipping
channels from the supply and exhaust fans with spring
isolators.
[ ] Check all supply and exhaust fan spring isolators for
proper...

connections. Refer to Detail A inFigure 12, p. 25for the
location of these drain connections.
A condensate trap must be installed due to the drain connection being on the “negative pressure” side of the
fan. Install the P-Traps at the unit using the guidelines in
Figure 41.
Pitch the drain lines at least 1/2 inch for every 10 feet of
horizontal run to assure proper condensate flow. Do not
allow the horizontal run to sag causing a possible double-
trap condition which could...

6. Use screw gun to unscrew the two screws that hold the
fan shipping bracket. The bracket should drop down
but still remain engaged with a hook on the bracket.
7. Go to the other side of the unit and follow the procedure
 for inlet louver and door removal
(see steps1-6
 ).
8. Hold the bracket with one hand and remove remaining two
 screws. 9. Remove the bracket and all the removed screws from
the
 unit.
Important: Mak
 e sure there are no screws remaining in
the coil area....

O/A Sensor and Tubing Installation
An Outside Air Pressure Sensor is shipped with all units
designed to operate on variable air volume applications or
constant volume units with 100% modulating exhaust w/
Statitrac.
On VAV systems, a duct pressure transducer and the
outside air sensor is used to control the discharge duct
static pressure to within a customer-specified parameter.
On CV & VAV units equipped with 100% modulating
exhaust w/Statitrac, a space pressure transducer...

Evaporative-Cooled Condenser Make-up
Water and Drain Line Installation
Make-up Water and Drain Lines
Water Supply Source
The supply line should be designed to provide a minimum supply
 of water within customary domestic supply
pressures, 35 to 60 psig; dynamic pressure (measured
with the valve open) which will allow approximately 30
GPM to enter the sump through the makeup water valve,
when the sump is empty. The unit uses about 2-4 GPM.
Attach a hand valve at the inlet for...

Make Up Water Solenoid Valve
This valve is controlled by the UCM based on water level in
 the sump, as well as whether a call for mechanical
cooling exists. During low ambient temperatures, the
solenoid valve will be de-energized preventing water from
further filling sump.The sump drain valve opens to empty
sump of water. Operation can be extended to 10 deg by
providing an optional sump heater.
Drain Valve
The drain valve is shipped to “drain during power loss conditions”.
