Features and
Benefits
Foil-Faced Insulation
All panels in the evaporator section of the
unit have cleanable foil-faced insulation.
All edges are either captured or sealed to
ensure no fibers get into the airstream.
Factory Built Roof Curbs
Available for downflow units. Only two
roof curbs for the entire Precedent line
simplifies curb selection.
Flexibility
Units are built to order in our standard
“shortest in the industry” ship cycle time.
Fresh Air
0 - 25% manual or 0 - 50% motorized
outside air hoods are available.
High Pressure Cutout
This factory-installed option is offered for
units that do not have High Pressure
Cutout as standard. All 3-phase units with
scroll compressors include High Pressure
cutout as standard.
High Static Drive Accessory
Available on many models, this high
static drive accessory extends the
capability of the standard motor. Avoid
expensive motors and operating costs by
installing this optimized sheave
accessory.
Hinged Access Doors
These doors permit easy access to the
filter, fan/heat,
and compressor/
control sections.
They reduce the
potential roof
damage from
screws or sharp
access door
corners.
LonTalk
®
Communications
Interface
The LonTalk
communications
interface allows
the unit to
communicate as a Tracer™LCI-V device
or directly with generic LonTalk Network
Building Automation System Controls.
Phase Monitor
Phase monitor shall provide 100%
protection for motors and compressors
against problems caused by phase loss,
phase imbalance, and phase reversal.
Phase monitor is equipped with an LED
that provides an ON or FAULT indicator.
Power Exhaust Option
This option is available on downflow units
and provides exhaust of the return air,
when using a downflow economizer, to
maintain proper building pressurization.
Great for relieving most building
overpressurization problems.
Progressive Tubular Heat Exchanger
The compact cabinet features a tubular
heat exchanger in low, medium and high
heat capacities.
The heat exchanger is fabricated using
stainless steel burners and corrosion-
resistant aluminized steel tubes as
standard on all models. It has an induced
draft blower to pull the gas mixture
through the burner tubes. The heater has
a direct spark ignition system which
doubles as a safety device to prove the
flame.
Gas electric Precedent models exceed all
California seasonal efficiency
requirements. They also perform better
than required to meet the California NOx
emission requirements.
Quick-Access Panels
Remove two screws for access to the
standardized internal components and
wiring.
Quick-Adjust Idler Arm
With the Quick-Adjust Idler Arm, the belt
and sheaves can be quickly adjusted
without moving the mounted fan motor.
The result is a major savings in time and
money.
Reference or Comparative Enthalpy
Measures and communicates humidity
while maximizing comfort control.
Sloped Drain Pans
Every Precedent unit has a non-
corrosive, removable,
double-sloped
drain pan that’s
easy to clean and
reversible to allo w
installation of drain
trap on either side
of the unit.
Standardized
Components
Components are placed
in the same location on
all Precedent units.
Familiarize yourself with one Precedent
and you are familiar with every
Precedent.
Due to standardized components
throughout the Precedent line,
contractors/owners can stock fewer
parts.
Supply and/or Return Air Smoke
Detector
With this option installed, if smoke is
detected, all unit operation will be shut
down. Reset will be
manual at the unit. Return
Air Smoke Detectors
require minimum
allowable airflow when
used with certain models.
Thermal Expansion Valve
Available for a wider
range of applications.
Trane Communication
Interface (TCI)
Available factory or field installed. This
module when applied with the ReliaTel™
easily interfaces with Trane’s Integrated
Comfort
TM
System.
