Trane UCCA Installation and operating instructions

SAFETY WARNING
Only qualified personnel should install and service the equipment. The installation, starting up, and servicing of heating, ventilating, and air-
conditioning equipment can be hazardous and requires specific knowledge and training. Improperly installed, adjusted or altered equipment
by an unqualified person could result in death or serious injury. When working on the equipment, observe all precautions in the literature and
on the tags, stickers, and labels that are attached to the equipment.

Important
Environmental Concerns!
Scientific research has shown that certain man-made
chemicals can affect the earth’s naturally occurring
stratospheric ozone layer when released to the
atmosphere. In particular, several of the identified
chemicals that may affect the ozone layer are refrigerants
that contain Chlorine, Fluorine and Carbon (CFCs) and
those containing Hydrogen, Chlorine, Fluorine and
Carbon (HCFCs). Not all refrigerants containing these
compounds have the same potential impact to the
environment.Traneadvocatestheresponsiblehandlingof
all refrigerants-including industry replacements for CFCs
such as HCFCs and HFCs.
Responsible Refrigerant Practices!
Trane believes that responsible refrigerant practices are
important to the environment, our customers, and the air
conditioning industry. All technicians who handle
refrigerants must be certified. The Federal Clean Air Act
(Section 608) sets forth the requirements for handling,
reclaiming, recovering and recycling of certain
refrigerants and the equipment that is used in these
service procedures. In addition, some states or
municipalities may have additional requirements that
must also be adhered to for responsible management of
refrigerants. Know the applicable laws and follow them.
ATTENTION: Warnings, Cautions, and Notices appear at
appropriate sections throughout this literature. Read
these carefully:
WARNING
Indicates a potentially hazardous
situation which, if not avoided, could
result in death or serious injury.
CAUTION sIndicates a potentially hazardous
situation which, if not avoided, could
result in minor or moderate injury. It
could also be used to alert against
unsafe practices.
NOTICE:

WARNING
Proper Field Wiring and Grounding
Required!
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes. Failure to
follow code could result in death or serious injury.
WARNING
Personal Protective Equipment (PPE)
Required!
Installing/servicing this unit could result in exposure to
electrical, mechanical and chemical hazards.
• Before installing/servicing this unit, technicians
MUSTputonallPersonalProtectiveEquipment(PPE)
recommended for the work being undertaken.
ALWAYSrefer toappropriateMSDS sheets and OSHA
guidelines for proper PPE.
• When working with or around hazardous chemicals,
ALWAYS refer to the appropriate MSDS sheets and
OSHA guidelines for information on allowable
personal exposure levels, proper respiratory
protection and handling recommendations.
• If there is a risk of arc or flash, technicians MUST put
on all Personal Protective Equipment (PPE) in
accordance with NFPA 70E or other country-specific
requirements for arc flash protection, PRIOR to
servicing the unit.
Failure to follow recommendations could result in death
or serious injury.

Warnings, Cautions and Notices
CLCH-SVX009A-EN 3
Performance air handler model UCCA is not designed for
use with UV lights.
WARNING
Harmful Ultraviolet (UV) Lights!
Failure to follow instructions below could result in
death or serious injury and equipment damage.
Do not field install ultraviolet lights in this air handling
unit for the intended purpose of improving indoor air
quality. High intensity C-band ultraviolet light is known
to severely damage polymer (plastic) materials and
poses a personal safety risk to anyone exposed to the
light without proper personal protective equipment
(can cause damage to eyes and skin). Polymer materials
commonly found in HVAC equipment that may be
susceptible include insulation on electrical wiring, fan
belts, thermal insulation, various fasteners and
bushings. Trane accepts no responsibility for the
performance or operation of our air handling equipment
in which ultraviolet devices were installed outside of
the Trane factory.

General Information
Operating Environment
Performance Climate Changer™ air handler model UCCA
isdesignedfor indoorapplications.Whenconsideringthe
placementoftheairhandler,itisimportanttoconsiderthe
operating environment. The acceptable ambient
temperature range for unit operation is -40ºF to 140ºF
(-40ºC to 60ºC).
Do not operate unit above maximum fan speed or unit
airflow as shown in the unit fan curves. (See CLCH-
PRC024A-EN Performance Climate Changer Air Handler
Model UCCA catalog.) Unit operation at greater than
maximum fan speed can drastically reduce bearing life
and result in a catastrophic failure. Operating at greater
than the maximum allowable airflow in the cooling mode
may result in unsatisfactory operation due to moisture
carryover from the coil. In addition, it is often not
economical to operate a unit at its maximum fan speed
due to the greater motor power requirements.
Donotoperateunitswithelectricheatbelowtheminimum
airflow listed (see Table 11, page 44). This is to prevent
excessive leaving air temperatures and electric heat limit
trips.
Do not operate a hydronic (or steam) coil and electric heat
simultaneously. This is to prevent excessive leaving air
temperatures and limit trips. Electric heat units are
equipped with a lockout switch to disable the electric
heater if the temperature of the hydronic (or steam) coil is
greater than 95°F (35C).
For heating applications, a special motor may be required
towithstandthehighertemperatures.MotorswithClassB
insulation are acceptable for ambient temperatures up to
104º F, while motors with Class F insulation can withstand
ambient temperatures to +140º F (60º C).
Note: Units with UL approval have a maximum ambient
temperature requirement of 104ºF. The customer
should provide adequate freeze protection for the
coils. See “Routine Maintenance,” page 54 for
more information.

Factory-Mounted Controls
Performance air handlers are available with an optional
control interface. This package can be used as part of a
stand-alone operation, or it can be fully integrated into a
comprehensive control system. The Trane Earthwise™
system incorporates the benefits of factory-installed
controlsandlinkstheairhandlertotheTracer™SCsystem
controls building management system. This option is
designed to lower installation costs and risk while
dramatically improving the quality of the application and
the performance of the air handler. The entire air handler
controlsystem isengineered,mounted,wired,andtested
before leaving the factory. As a result of strict quality
manufacturing methods, these control options bring
consistency and reliability to the control-system package
and provide single-source responsibility.
The following control devices are available as standard
mounted on fan sections:
• Variable-frequency drives (VFDs)
• Control interface package
– Fan motor disconnect switch
– Fused transformer(s)
– Fan contactor
– Customer terminal strip for field-provided controls
• Various end device options, including:
– Low limit protection
– Condensate overflow switch
– Fan status switch
– Filter status switch
– Discharge air sensor
– Mixed air sensor
– Damper actuator
Wiring
Entrances are generally provided for field-installation of
high and low voltage wiring through a pipe/nipple
connection in the unit depending on unit configuration
with or without factory-mounted controls. Before
installation, consider overall unit serviceability and
accessibility before mounting, running wires (power),
makingpenetrations, ormounting anycomponentstothe
cabinet.

WARNING
Proper Field Wiring and Grounding
Required!
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes. Failure to
follow code could result in death or serious injury.
