Introduction
Use this manual to install, startup,
operate, and maintain the CDQ
desiccant wheel module for Trane
Climate Changer™ air handlers.
Carefully review the procedures
discussed in this manual to minimize
installation and startup difficulties.
The startup and adjustment
procedures discussed in this manual
should be done by qualified,
experienced HVAC technicians.
Your personal safety and the proper
operation of this machine depend
upon the strict observance of these
precautions.
Product Information
Trane CDQ™ (Cool, Dry, Quiet)
desiccant dehumidification wheel is
a water vapor transfer tool. The
Trane CDQ™ desiccant wheel is used
to enhance the dehumidification
performance of a traditional cooling
coil. The wheel is configured in
series with the coil such that the
“regeneration” side of the wheel is
located upstream of the coil and the
“process” side of the wheel is
located downstream of the cooling
coil. The wheel recirculates the water
vapor trapped downstream of the
cooling coil back into the air
upstream of the coil where the coil
removes it through condensation.
This process is accomplished
without the need for a second
regeneration air stream. The addition
of the CDQ desiccant wheel to the
system enhances the
dehumidification performance of the
traditional cooling coil.
Protecting the
Environment
World environmental scientists have
concluded, based on the best
currently available evidence, that
ozone in our upper atmosphere is
being reduced due to the release of
CFC (chlorofluorocarbon) fully
halogenated compounds.
Trane urges that all HVAC service
technicians working on Trane
equipment, or any manufacturer’s
products, make every effort to
eliminate, if possible, or vigorously
reduce the emission of CFC, HCFC
(halocarbon that contains fluorine,
chlorine, carbon, and hydrogen), and
HFC (halocarbon that contains only
fluorine, carbon, and hydrogen)
refrigerants to the atmosphere
resulting from installation,
operation, routine maintenance, or
major service on this equipment.
Always act in a responsible manner
to conserve refrigerants for
continued use even when acceptable
alternatives are available.
Refrigerant used in any type of air-
conditioning or refrigerating
equipment should be recovered for
reuse, recovered and/or recycled for
reuse, reprocessed (reclaimed), or
properly destroyed, whenever it is
removed from equipment. Never
release it to the atmosphere!
