• High Efficiency

Impack performance is among the highest
in the industry.

• Climatuff® Compressor

Protection against chemical, electrical, and
mechanical stresses are built in for
efficiency and a longer life. The compressor
is backed by a 5-year limited warranty, with
an optional warranty for 5 more years.

• Time Defrost Control

This is an electronic, time initiated, tempera­ture terminated defrost system that offers a
choice of 50, 70, or 90 minute cycles. The
time override limits the defrost cycle to 10
minutes.

• Convertibility

Impack units are easily converted from
horizontal to downflow with the removal of
one screw from each panel. Accordingly, the
need to stock both dedicated horizontal and
dedicated downflow models has been
eliminated.

• Installation

The ease of installation and application
flexibility exhibited through the design
reduce both field time and material.

• Application

The low profile horizontal duct take-offs
eliminate the need for expensive transition
ducts in crawl space applications.

• Commonality

The common cabinet among the TCC’s,
WCC’s, and YCC’s minimizes both the
training of sales and service personnel and
replacement parts inventory.

• Flexibility

A single curb fits the entire Impack line from

1.5 tons through 5 tons thereby providing
great installation flexibility on shopping
malls, factories, schools, and other
commercial buildings where a mix-match of
tonnages and utilities is desired.

Features and
Benefits

Standard Equipment

• Water-Shed™ Base

Superior water integrity is accomplished
with the Water-Shed™ base pan having
elevated downflow openings and a perim­eter channel that prevents water from
draining into the ductwork.

• Easy Access

All electrical components can be diagnosed
and replaced with the removal of one panel
that is attached with two screws.

• Service

All wiring is both numbered and color coded
thereby reducing training and servicing
costs related to circuit tracing and compo­nents replacements.

• Maintenance

A plug on the outdoor fan motor allows the
top cover to be removed completely without
the hassle of cumbersome wires. The
unique service orifice ring allows the indoor
fan motor/blower to be removed as a unit.

• Plate Fin Coil

Refrigeration coils are built with internally
enhanced copper tubing for high efficiency
with less coil area.

• Shipping

Unit dimensions were carefully selected to
provide an attractive aspect ratio and for
shipping and handling considerations.

• Good Neighbor

Most units can be installed flush with the
residence or building thereby minimizing the
ground space required. Blankets of
insulation reduce blower noise and energy
losses to the outside environments.

• Rooftop Mounting

The cabinets are physically smaller than
most competitive models. This means less
intrusive installations on residential rooftops
where aesthetics are critical.

• Handling

The three-way wooden skid allows for easy
loading between the wheel wells on pickup
trucks for transporting to job sites.

• Structure

The units are lighter weight through the use
of high technology components thereby
reducing mounting structure requirements
and difficulty when handling.

• Duct Flanges

Only Impack has downflow duct flanges for
duct attachments that preserve the built-in
water integrity.

• Corrosion

The drain pan is engineered material and
eliminates the need for coatings and sealers
to prevent sweating and corrosion. The
heavy gauge, zinc-coated steel cabinet has
a weather resistant enamel finish that stays
attractive and protects your investment for
years.

• Low Ambient Control

Zero degree ambient cooling is accom­plished with two kits. One for low cost
installations when full tonnage is not
needed. The other kit maintains head
pressure and full capacity at zero degrees.

• Quality and Reliability Testing

We perform a 100% coil leak test at the
factory. The evaporator and condenser
coils are leak tested at the factory. The
evaporator and condenser coils are leak
tested at 200 psig and pressure tested to
450 psig respectively. In addition the Impack
designs were rigorously rain
tested at the factory to ensure water
integrity. Shipping tests are performed to
determine packaging requirements. Factory
shake and drop tests are used as part of
the package design process to help assure
that the unit will arrive at the job site in top
condition. Additionally, all components are
inspected at the point of final assembly.
Substandard parts and components are
identified and rejected immediately. Every
unit receives a 100% run test before leaving
the production line to make sure it lives up
to rigorous Trane® requirements. We at
Trane test our designs at our factory and not
on our customers!

Impack
Accessories

• Standard Thermostats

No special thermostats are needed with
Impack units.

• Filter Frame Kit

The Impack filter frames accept standard
filters and fit inside the unit. The frame kits
function in either horizontal or downflow
duct configurations.

• Coil Guard Kit

The guards are vinyl coated 1" x 3" wire
grills. These grills will protect the coil from
hail, kids with sticks as well as normal
shipping and installation handling damage.

• UNI-CURB™

One universal curb fits all the Impack
models. It ships knocked down. The curb
design incorporates the popular locking tabs
for quick and easy assembly. Full perimeter
curbs are also available for all models.

• 25% Fresh Air Kit

The kit installs over the horizontal return air
opening with six screws for downflow require­ments. It can be used on horizontal air flow
applications by cutting a hole in the return
air duct or in the unit filter access panel.

• Rectangular to Round Duct Kits

The adapter kit can be used in either
horizontal or downflow applications.

• Low Ambient Kit

An EDC provides low ambient cooling to 0° F
with some reduced capacity and protects
the system against evaporator icing during
other unusual cooling conditions.

• Fan Delay Relay Kit

This solid state kit is a time delay that keeps
the indoor blower on for about ninety
seconds and increases the SEER. It wires
into the low voltage unit pigtails.

• High Static Motor Kit

Contains a higher torque indoor fan motor.

• Lifting Lug Kit

Four reusable lugs in each kit allow units to
be easily lifted to rooftop installations. These
lugs snap (no screws required) into slots in
the unit drip lip channel.

• Start Kit

The kit mounts in the control box for those
installations with specific conditions such as
excessive voltage drop due to long wires.
(This is a capacitor and start relay kit and is
not a PTC device.) This kit can be a good
specification buster!

IPB-99-7-EN-10-6-99 5

• Economizer

The economizer fits inside the unit with only
the rain hood and barometric relief on the
outside. Cabling (with polarized plugs) is
shipped with the economizer. This cabling is
easily routed to the control box where it
terminates in low voltage pigtails. The
economizer features a fully modulating low
voltage motor eliminating the need for any
high voltage wiring. The economizer must
be used with the filter frame kit . . . no return
air filter in the economizer kit. A dr y bulb
sensor is shipped with the economizer. The
economizer was not designed for use in
horizontal applications. Heat pump applica­tions require a relay kit.

• Enthalpy Control Kit

For those applications specifying an econo­mizer with enthalpy control, this control can
be used in place of the dry bulb sensor or,
alternately, two enthalpy controls can be
paired to provide differential enthalpy control.

• Single Power Entry Kit

The kit minimizes installation costs by
reducing the load center circuit requirement
and reducing the number of circuit pulls
needed.

Economizer Controls

The standard equipment offering is a fixed dry
bulb changeover control. In addition to the
standard offering, there are two other field
installed control accessories.

Enthalpy Control

Replaces the dry bulb control with a solid
state dry bulb and wet bulb changeover
controller which has a fully adjustable set
point. Enthalpy control offers a higher level of

energy savings potential than the standard
dry bulb control due to the additional wet bulb
sensing capability.

Differential Enthalpy

Replaces the standard dry bulb control with
two enthalpy sensors that compare total heat
content of the indoor air and outdoor air to
determine the most efficient entering air
source. This control option offers the highest
level of energy efficiency available.
