models with conventional electric resistance heaters  
• 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.

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

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.  
Standard Wall Sleeve (Polymer)  
Insulated polymer wall sleeves combine all of the  
above features with factory-installed insulation. The  
insulation helps to reduce heat loss, save energy, pro-  
vide better sound absorption, and reduce the risk of  
sleeve sweating.

INDOOR FILTER  
New two-piece removable filters easily slide in and  
out from the front of the PTAC unit and are inter-  
changeable. The front panel does not need to be  
removed to access or change the filters. The filters are  
washable and permanent.  
Two-Piece Indoor Filter  
WASHABLE VENT AIR FILTER  
The unique vent system is activated by a two-position  
control. Fresh outside air is redirected by the vent door  
to an inside low-pressure area. A molded plastic filter  
prevents dirt and debris from entering the room side of  
the unit. The vent mechanism is made from noncorro-  
sive material ensuring reliable operation. A magnet on  
the door and high-pressure airflow create a tight, draft-  
free seal when the vent door is closed.  
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).

PRODUCT FEATURES AND BENEFITS (cont)  
EASY ACCESS TO CHASSIS  
Access to the chassis simply requires removing four  
screws and then sliding the chassis out of the sleeve  
for service.

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.

NOTE: If it is necessary to remove 100% of the con-  
densate, the Carrier Drain Kit (Part No.: DRAIN-KIT-

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.

HEAT PUMP ENERGY  
SAVINGS  
Heat pumps save more on operat-  
ing costs during the heating cycle  
than heat/cool models. The table  
below shows that the higher initial  
cost of purchasing a heat pump is  
quickly made up in lower operating  
costs.

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.  
• For all applications with an accessory subbase,  
wall sleeve must extend 31/4 in. minimum into

maximum above floor (including carpeting) to  
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.  
Corrosion-Protected Polymer Sleeve  
Non-Insulated Polymer Wall

Polymer Wall Sleeves  
Choose a polymer wall sleeve for maximum protec-  
tion and appearance.  
All Carrier’s polymer wall sleeves are made from a  
molded polymer that is designed for strength and dura-  
bility. This material has excellent corrosion resistance  
and a flammability rating of UL94-5V.  
Part No.: WALL-SLEEVE-1PK  
Part No.: WALL-SLEEVE-9PK  
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.

mounted in a corner or off-center in a room.  
Accessory Air Deflector  
NOTE: The lateral air deflector is not compatible with  
previous PTAC models.  
Curtain Deflector  
Part No.: CURTDFL-52CP-1PK

being blown into the discharge air.  
Curtain Deflector Kit  
Security Door Kit  
Part No.: SECURITY-DOOR  
This key-locking security door kit prevents unautho-  
rized access to the unit’s heating and cooling controls  
and prevents tampering with units in public locations  
and institutions. This field-installed accessory includes  
two matching keys and fits all Carrier 52P and 52C  
models. Keys are common to all Security Door kits.

FIELD-INSTALLED ACCESSORIES  
(52P AND 52C) (cont)  
Replacement Filters  
Part No.: AIR-FILTER-10PK  
The Carrier 52P and 52C model replacement air filters  
come in packages of 10. The filters save energy by pre-  
venting the evaporator coils from being plugged with dirt  
and lint. These economical and sturdy filters are inter-  
changeable and may be washed, vacuumed, and reused.  
Easily Replaceable Filters  
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.)
