APPLICATIONS
Whether you are designing a new structure or replac-
ing packaged terminal air conditioning units in an
existing building, Carrier will meet your needs.
• Hotels and motels
• Nursing homes and assisted living care centers
• Offices
• Apartments
• Single-family dwellings
• Home conversions and residential add-ons
Lower Operating Costs And Reliable Comfort
For The Occupant

• Individual units allow tenants to choose the degree
of comfort and operating economy.
• Rapid servicing reduces downtime: complete chas-
sis can be replaced in minutes without disrupting
other occupants.
• Each unit operates independently of other units in
the building. No dependency by building on central
HVAC system.
NEW CONSTRUCTION
The Carrier 52P and 52C Packaged Terminal Air Con-
ditioning (PTAC) unit is designed to meet the needs of
the architect, engineer, and contractor. For unit instal-
lation, Carrier’s expert support network will assist in
all applicable aspects of the construction project, from
preparing a budget to start-up.
ADVANTAGES FOR NEW CONSTRUCTION
Design Flexibility For The Architect/Engineer
• Super-quiet performance, indoors and out
• No bulky duct system
• No separate equipment room
• No water towers or additional cooling equipment
• No complex match-up of different HVAC
components
• Less sensitivity to building orientation (sun, wind,
shade)

rior appearance
Initial Cost Savings For The Building Owner
RETROFIT/REPLACEMENT
If you are replacing a unit in an existing wall sleeve,
your options include:
• Replace the existing wall sleeve with a Carrier
Weather Last™ sleeve. See accessory sleeve sec-
tion for selecting the correct sleeve for your appli-
cation. Note, in most cases, when replacing the wall
sleeve, the exterior grille must also be replaced.
• Use an existing sleeve and exterior grille. The
Carrier 52P and 52C series PTAC will fit into most
major competitors wall sleeves/grilles, including
GE, Amana, Trane, Bryant, Carrier 52S and Carrier
52B, and NO accessory retrofit kit is required.
Carrier units will also retrofit into Friedrich T series
and ZoneAire wall sleeves, with a required wall
sleeve extension (see accessory Friedrich Retrofit
Wall Sleeve Adapter).
• No expensive component HVAC system purchase
• No equipment room or maintenance engineering
staff
• Two-part delivery to minimize on-site damage
• Weather-protected wall sleeve that goes in place
during construction; chassis that slides in place after
construction
• No seasonal changeover required for cooling or
heating — units are self-contained comfort systems
IMPORTANT: All other sleeve or exterior grille
retrofit applications need prior approval from
Carrier. Please contact your Carrier representative
for assistance.
CARRIER WARRANTY
Carrier’s five-year warranty is the most comprehen-
sive in the industry. Carrier provides:

APPLICATIONS (cont)
APPLICATION
Oversizing
If a PTAC unit is oversized (cooling capacity is greater
than required capacity for the specific application), the
unit will cool the space down to the desired tempera-
ture too quickly.
CONSIDERATIONS
Installation instructions are shipped with all PTAC
units. It is important that air conditioning systems be
properly sized and installed for each application in
order to achieve the desired temperature and humidity
levels within the space to be conditioned. It is strongly
recommended that a professional engineer match the
PTAC units with the building structure and climate.
The unit will cycle on and off, however, dehumidifica-
tion only takes place when the unit is operating. The
result of this type of application in a hot and/or humid
climate would be a cool, yet excessively humid, space.
The following application considerations are all
important in choosing the proper PTAC system for the
building structure.
Air Infiltration
Excessive air infiltration can intensify problems asso-
ciated with undersizing or oversizing a PTAC unit.
This can be the cause of insufficient cooling, dehumid-
ification, or heating. Sources of air infiltration include
vents, gaps around windows and doors, and improp-
erly sealed floors, ceilings or wall joints.
Undersizing
If a PTAC unit is undersized (cooling capacity is less
than required capacity for an application), the unit will
not be able to cool the space down to the desired tem-
perature during very hot days. The result could be
warm and humid or warm and dry conditioned space.

NO-RUST WEATHER LAST™
WALL SLEEVE AND FRONT
PANEL
The indoor front panel and polymer wall sleeve use
nonmetallic compounds that never rust or corrode, do
not support combustion, and do not give off toxic
fumes. The weather-resistant feature exceeds require-
ments of Underwriters’ Laboratories and resists dam-
age caused by impact and scratching. The Weather
Last feature also insulates and has up to 10 times the
acoustic absorption of metal cabinets.

HIDDEN CONTROLS
Fan Cycle Switch
The fan cycle switch allows the fan to operate in
2 modes:
The factory-wired control box houses all control com-
ponents and is quickly accessible without removing
the chassis from the wall sleeve. By simply removing
two screws on control box, the hinged door lowers,
providing quick access to all the electrical compo-
nents. The wiring diagram is located on the front of the
control box door.
• Continuous — This setting allows the fan to run
continuously, circulating air even when the temper-
ature setting has been satisfied. This setting, which
helps to keep the room temperature closer to the
thermostat setting, is used for maximum comfort.
• Cycle — This setting allows the fan to cycle on and
off with the compressor during heating or cooling.
The fan stops when the temperature setting is
reached. The longer unit off-time makes this option
more energy-efficient with only slightly wider vari-
ations in room temperature.
NOTE: On wall thermostat models, the fan cycle/
continuous feature is typically located at the wall
thermostat.
Temperature Limiter and Control
Knob
The limiter reduces operating costs by allowing the
owner to control the range of cooling and heating tem-
peratures available to the occupant. It is located under
the front panel on control box, out of the occupant’s
sight. Each setting on the limiter is equivalent to 5° F
and the range of temperature settings available to the
owner is from 60 to 90 F. The limiter is not pre-set at
the factory (providing full range for the occupant).
Outdoor Air Vent Control
Control of the outdoor-air vent is handled by a vent
handle located under the front panel on the left side of
the unit. This handle rotates to manually open and
close the outdoor vent.
The vent will provide 50 cfm of fresh air.
NOTE: If more fresh air cfm is required, a Power-Vent
Kit is available (see accessories).

ENHANCED COPPER TUBING
Enhanced copper tubing is more efficient and durable
and can be repaired in the field, if required.
Because copper is a very stable metal, it is durable and
resists corrosion. Enhanced copper tubing increases:
• heat transfer capability
• the efficiency of the cooling and heating processes
• thermal conductivity (by creating additional tube
surface and turbulent refrigerant gas flow)
Every Carrier PTAC coil undergoes thorough leak test-
ing and pressure testing up to 350 lb per square inch.
SEAMLESS BASEPAN
Seamless drawn basepan walls add protection against
water accumulation resulting from storm-driven rain
with heavy wind.
Carrier’s deep basepan holds up to 11/2 gallons of
water without spilling. Closed cell foam insulators are
located between the basepan and coils, keeping coils
from direct contact with the basepan and providing
additional protection against corrosion.
Enhanced Copper Tubing
CONDENSATE DRAIN VALVE
The temperature-activated drain valve opens when the
outdoor temperature drops below 45 F to prevent
water from freezing in the basepan.
Condensate Drain Valve Prevents
Water from Freezing in Basepan
CONDENSATE REMOVAL
SYSTEM
Carrier’s 52P and 52C Series units have an improved
condensate (water) disposal system. In addition to
slinger ring technology, Carrier has developed and pat-
ented a Condensate Suction Port. The suction port,
along with the slinger ring, draws in water which is
sprayed up onto the outdoor coil. The water then evap-
orates, thus providing better disposal of excess con-
densate, improving unit efficiency.

HEAT PUMPS PAY THEIR
OWN WAY
How The Heat Pump Works
Heat pump models are available at a nominal addi-
tional cost. In many locales, the payback is realized in
just a few months. Cost and payback details are pro-
vided on the next page.
Special Features
Two-Stage Indoor Thermostat:
The indoor thermostat senses the indoor temperature
and automatically turns on the electric heat to warm
the room quickly. After the desired temperature condi-
tions have been satisfied, the thermostat automatically
switches to heat pump mode. If compressor failure
occurs, the thermostat will provide backup electric
heat automatically.
In Hot Weather:
Carrier’s PTAC units provide indoor comfort in the
same manner as conventional air conditioners, remov-
ing heat and humidity from indoor air. The heat and
humidity is released to the outdoors. Carrier’s high-
efficiency design saves energy and reduces cooling
costs.
Outdoor Thermostat:
During the heating cycle, the outdoor thermostat
senses outdoor coil temperature. It switches the unit to
electric heat mode when the outdoor coil temperature
is 20 F or below (approximately 35 F outdoor-air tem-
perature). The thermostat switches the unit back to
heat pump mode when the outdoor coil temperature
rises above 40 F, which is enough to provide heat
to meet demand. The entire operation is completely
automatic.
Reversing Valve:
In Cool Weather:
The reversing valve provides quiet refrigerant flow
after the unit shuts off. The valve controls the direction
of refrigerant flow for both heating and cooling func-
tions and remains energized as long as the controls are
in the heat position. When the cooling controls are
activated, the valve automatically reverses to the cool-
ing position.
When the outdoor coil temperature is above 20 F
(approximately 35 F outdoor-air temperature), the
heat pump draws heat from outdoor air and uses it to
heat indoor air. Since heat is transferred and not pro-
duced, Carrier’s heat pump uses less electricity and
reduces energy costs significantly.
Manual Compressor Override Switch:
This switch completely locks out the compressor. Note
that the compressor and heater do not operate at the
same time, thus conserving energy.
In Sub-Freezing Weather:
When the outdoor coil temperature falls below 20 F
(approximately 35 F outdoor-air temperature), the
unit automatically switches on a built-in electric
heater. The compressor stops and a blower circulates
warm air produced by the heater. When the outdoor
coil temperature rises above 40 F, heat pump operation
resumes automatically.

Important Sleeve Installation Considerations:
• All Carrier's sleeves are self pitching and must be
mounted level in all directions. (Do not use rails
to level sleeve.)
• The sleeve should be caulked on all sides, includ-
ing both inside and outside the building.
• If more than 4 in. of wall sleeve projects into the
room, an accessory subbase must be used for
support.
IMPORTANT: Insulated Polymer Wall sleeve pro-
vides superior sound absorption, reduces heat loss
and prevents sleeve sweating.

allow for proper fit of subbase.
• For applications where the wall sleeve is
mounted flush to the exterior of the building
(or recessed in), Carrier recommends a field-
supplied drip edge be installed to prevent water
infiltration into the building.
• Insulated wall sleeves should be considered for
superior sound absorption, to reduce heat loss
and to prevent sleeve sweating, a condition that
can occur when the outside temperature is cold
and the indoor conditions are warm and humid.

Carrier’s accessory non-insulated polymer wall sleeve,
provides a superior appearance and protection for
many applications.
The sleeve surface is textured to prevent shine and
hide scratches. The rib configuration on the sleeve bot-
tom, allows easy chassis removal and aids in drainage.
The locating holes in the side and top panels, allow
easy fastening of the sleeve to wall openings. Refer to
dimension drawings (pages 28 and 29) for typical wall
installation and dimensions.
For applications where weather conditions could
influence sleeve sweating, a condition that can occur
when the outside temperature is cold and the indoor
conditions are warm and humid, the Insulated Poly-
mer Wall sleeve should be considered.

The following guidelines must be followed in the ini-
tial selection of any alternate exterior grille or louver:
Y
1. The louver must have a minimum of 65% free area.
Free area is the minimum area of the opening in an
air inlet or outlet in which air can pass. Free Area
(%) = X/Y.
2. The louver should be attached to the wall sleeve in a
manner that will prevent recirculation of condenser
discharge air into the inlet. In most applications, baf-
fles, splitters, and/or gasket will be required between
the chassis tube end sheets and the louver to prevent
air recirculation.
The above criteria must be followed, since a louver
that is restrictive or allows recirculation will result in a
reduction of the unit’s capacity and efficiency and will
ultimately shorten the compressor life.

Energy Management Kit
Part No.: EM-KIT
This field-installed accessory kit allows individual
units to be turned on and off from a remote location.
The kit incorporates Carrier’s Freeze Guard protection
that prevents rooms from freezing during extreme or
extended cold periods. Under these conditions, the
Freeze Guard automatically disables front desk control
and allows the unit to maintain a temperature of at
least 50 F in the room. When the room reaches 65 F,
the Freeze Guard feature returns the unit control to the
front desk.
This kit interfaces to most energy management sys-
tems. When installed in locations other than the front
desk, the kit can control unit operation by receiving
signals from field-supplied devices such as motion
sensors or heat sensing detectors.
Control devices connected to the Energy Management
Kit must have normally open sets of contacts (when
the switch is open, the unit operates). A 24-volt trans-
former must be field supplied and connected to the
Energy Management Kit. (See typical wiring diagram
on page 49.)
