Filters
Medium Efficiency
Two-inch (51 mm) medium efficiency
throwaway fiberglass filters are installed
in the unit filter section.
Remote Human Interface Panel
The remote human interface panel (RHI)
can perform all the same functions as
the unit mounted human interface panel,
except the service mode function. A
single RHI can monitor and control up to
four units. The panel includes a 2 x 40
character clear language (English,
Spanish, or French) display, a red LED
light to indicate an alarm condition, a
simple 16-key keypad for making unit
setpoint and configuration changes, and
hinged access door. The panel can be
mounted up to 5,000 feet (1524 m) from
the unit and is wired to the inter-
processor communications bridge (IPCB)
mounted in the unit with twisted wire
pair communication wiring and 24V
wiring.
Generic Building Automation System
Module (GBAS)
The GBAS module is for use with a non-
Trane building management system. The
module provides a binary input for
demand limiting, four analog inputs for
setpoint adjustment, and five relay
outputs for diagnostic reporting. Inputs
can use a potentiometer or 0-5 vdc
signal.
Ventilation Override Module (VOM)
The VOM allows you to program the unit
with up to five ventilation sequences:
smoke purge, evacuation, pressurization,
purge, and purge with duct control.
Typically, a hard-wire short from a
smoke detector or fire control panel will
cause a binary input on the VOM to
close, thus causing the programmed
sequence to occur.
Trane Communication Interface (TCI)
The TCI provides interface to a Trane
Integrated Comfort™ system (ICS). It
allows remote control and monitoring of
the self-contained unit using a personal
computer with Tracer
®
building
management software.

Flexible Horizontal Discharge Plenum
• Low and Standard Height
Units are provided with a factory installed
horizontal discharge plenum that permits
multi-directional duct connections. The
plenum is insulated with two inches (51
mm) of 1.75 lb. (0.79 kg) density fiberglass
for sound attenuation. Discharge
openings can either be field cut or factory
cut based on duct dimensions supplied by
the customer. A two-inch duct collar is
provided for field duct connections. On
unit sizes 20-38 tons, the low height
plenum is 24
5
/
8
inches (625 mm) and the
standard height plenum is 32
3
/
8
inches
(822 mm). On unit sizes 42-80 tons, the
low height plenum is 21
1
/
8
inches (537
mm) and the standard height plenum is
28
5
/
8
inches (727 mm).
• Extended Height, 45-inch (1143m)
Units are provided with a horizontal
discharge plenum that permits multi-
directional duct connections. The plenum
is insulated with four inches (102 mm) of
1.75 lb. (0.79 kg) density fiberglass for
sound attenuation. Double-wall perf is
also available. Discharge openings can
either be field cut or factory cut based on
duct dimensions supplied by the
customer. A two-inch duct collar is
provided for field duct connections.
High Duct Temperature Thermostat
A factory-supplied temperature limit
switch with reset element detects the
supply air duct temperature. This sensor
should be field-installed downstream
from the unit’s discharge in the supply air
duct. If the supply air duct temperature
exceeds 240 F (115.6 C), the unit shuts
down and displays a diagnostic. A manual
reset is required at the unit. The high duct
temperature can be adjusted at the
thermostat.
Plenum High Static Switch
A factory supplied sensor provides
additional protection from ductwork over-
pressurization. This sensor should be
field-installed downstream of the unit’s
discharge in the supply air duct.
Protective Coating
• Cabinet
The unit exterior and exposed interior
surfaces have a four to six mil coat of
protective coating.
• Coils
A three to five mil coat of protective
coating is applied to the coil using a
multiple dip-and-bake process.
Cupro-Nickel Condenser
One condenser is provided for each
compressor. The condensers are a shell-
and-tube design with removable heads
to allow mechanical tube cleaning. Tubes
are ¾-inch (19mm) OD and constructed
of copper cupro-nickel (90/10).
Stainless Steel Drain Pan
The drain pan is positively sloped,
fabricated from 304L stainless steel, and
insulated with ¾-inch (19 mm) of
1-lb. (0.5 kg) density fiberglass. The drain
pan contains a factory piped trap with
cleanout.
Dirty Filter Sensor
A factory installed pressure switch
senses the pressure differential across
the filters. When the differential pressure
exceeds 0.9-inches (23 mm) WG, contact
closure occurs.
A field installed indicator device may be
wired to relay terminals that indicate
when filter service is required. Contacts
are rated at 115 VAC and are powered
by a field supplied transformer.
