General Information

Unit Nameplate Locations

One Mylar nameplate is located on the outside upper left
corner of the control panel door. It includes the model
number, serial number, electrical characteristics, weight,
as well as other pertinent unit data. A small metal
nameplate with the model number, serial number, and
unit weight is located just above the Mylar nameplate. A
third nameplate is located on the inside of the control
panel.

Precautionary Measures

WARNING
Fiberglass Wool!
Product contains fiberglass wool. Disturbing the
insulation in this product during installation,
maintenance or repair will expose you to airborne
particles of glass wool fibers and ceramic fibers known
to the state of California to cause cancer through
inhalation. You MUST wear all necessary Personal
Protective Equipment (PPE) including gloves, eye
protection, mask, long sleeves and pants when working
with products containing fiberglass wool. Exposition to
glass wool fibers without all necessary PPE equipment
could result in cancer, respiratory, skin or eye irritation,
which could result in death or serious injury.
1. Avoid breathing fiberglass dust.
2. Use a NIOSH approved dust/mist respirator.
3. Avoid contact with the skin or eyes. Wear long-sleeved,
loose-fitting clothing, gloves, and eye protection.
4. Wash clothes separately from other clothing: rinse
washer thoroughly.
5. Operations such as sawing, blowing, tear-out, and
spraying may generate fiber concentrations requiring
additional respiratory protection. Use the appropriate
NIOSH approved respiration in these situations.
First Aid Measures
Eye Contact - Flush eyes with water to remove dust. If
symptoms persist, seek medical attention.
Skin Contact - Wash affected areas gently with soap and
warm water after handling.

Unit Description

Each Trane Commercial, Single-zone Rooftop Air Handler
is fully assembled and the applicable controls are tested
for proper operation before shipment.
Units ordered with direct expansion (DX) evaporator coils
are leak-tested, evacuated and a Nitrogen holding charge
of 30 psig is added.An optional roof curb for the W_HE
units are available from Trane. The roof curb kit must be
field assembled and installed according to the latest
edition of RT-SVN14*-EN.
Trane Commercial Rooftop Air Handlers (when ordered
with IntelliPak™ controls) are controlled by a
microelectronic control system. The network of modules
and their operation are significantly different than
conventional units and are referred to as Unit Control
