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)

• Optional architectural grille to permit custom exte-

rior appearance

Initial Cost Savings For The Building Owner

• 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

Lower Operating Costs And Reliable Comfort

For The Occupant

• Heat pump models offer substantial savings over

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.

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).

CARRIER WARRANTY

Carrier’s five-year warranty is the most comprehen-

sive in the industry. Carrier provides:

• Full coverage for parts and labor for first year.

• Four additional years of full coverage on sealed

refrigeration systems.

• Limited second through fifth year coverage on non-

refrigeration system parts.

IMPORTANT: All other sleeve or exterior grille

retrofit applications need prior approval from

Carrier. Please contact your Carrier representative

for assistance.

APPLICATIONS

APPLICATION

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 following application considerations are all

important in choosing the proper PTAC system for the

building structure.

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.

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.

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.

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.

QUIET OPERATION

Occupants and neighbors are protected against noise

intrusion. Indoor sound reduction is achieved because

of the unit’s design and its louvered front cover, indoor

scroll and blower, and heavy gage unit partition.

Rotary compressors provide quiet, reliable operation.

The indoor scroll provides a more uniform air

discharge.

The new aerodynamic split condenser shroud design

improves airflow and reduces outdoor noise, providing

a more relaxing outdoor environment. The new split

design allows for easy access to the outdoor coil to

facilitate routine cleaning of the coil. The propeller-type

fan design allows for efficient low-speed operation.

MOST EFFICIENT

system operates without bulky ductwork, separate

equipment room, and complex match-up of different

components. Heating and Cooling modes are available

without seasonal changeover.

EFFICIENT FAN MOTOR

An efficient, totally enclosed PSC (permanent split

capacitor) fan motor provides a choice of high or low

speeds for heating and cooling. A fan-only setting

provides air circulation. Thefanmotorrequiresno

maintenance and no lubrication.

PRODUCT FEATURES AND BENEFITS

(52P AND 52C)

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.

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.

Carrier’s metal wall sleeves are available in a variety

of sizes for most standard and deep wall applications.

All metal wall sleeves come with factory-installed

insulation, designed to minimize heat loss and reduce

outdoor noise transmissions into the room.

REMOVABLE FRONT PANEL

The louvered front panel fits firmly onto the chassis

and features easy removal for service. It provides front

air intake to enhance performance and quiet operation.

It also allows the option of flush mounting PTAC unit

to the floor. If desired, the front panel can be

secured to the unit with field-supplied screws. The

2 locking screws (if installed) are located behind the

removable filter handles.

ANTI-THEFT KNOBS

The anti-theft knobs are captured underneath the front

panel of the unit to prevent the knobs from being

removed or stolen.

changeable. The front panel does not need to be

removed to access or change the filters. The filters are

washable and permanent.

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.

HIDDEN CONTROLS

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.

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.

Theventwillprovide50cfmoffreshair.

NOTE: If more fresh air cfm is required, a Power-Vent

Kit is available (see accessories).

Fan Cycle Switch

The fan cycle switch allows the fan to operate in

2modes:

• 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.

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 11/2gallons 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.

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 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,

alongwiththeslingerring,drawsinwaterwhichis

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-

4PK) is recommended.

HEAT PUMPS PAY THEIR

OWN WAY

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.

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:

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.

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.

PRODUCT FEATURES AND BENEFITS (cont)

How The Heat Pump Works

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.

In Cool Weather:

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.

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.

Weather Last™ Wall Sleeve

For the best performance and longest life, Carrier

recommends genuine Carrier wall sleeves for all

installations.

All Carrier wall sleeves are built with a pitch of 1/4 in.

per foot; for self-pitching of the unit, the wall sleeve

must be installed level (any error should be pitched to

the outside). Overflow slots on the outside of the

sleeve are in place to divert excess water during severe

weather.

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.

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.

The sleeve's alpine mist color (a shade of beige)

closely matches the front panel and blends in well with

any inside or outside decor.

The polymer wall sleeve comes in both insulated (fac-

tory installed) or non-insulated, to meet the require-

ments of every application.

Insulated Polymer Wall Sleeve

Part No.: SLEEVE-INSUL-1PK

Carrier’s accessory insulated polymer wall sleeve, with

factory-installed insulation, provides superior sound

absorption, reduces heat loss and prevents sleeve

sweating, a condition that can occur when the outside

temperature is cold and the indoor conditions are warm

and humid.

Non-Insulated Polymer Wall

Sleeve

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.

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.

• For all applications with an accessory subbase,

wall sleeve must extend 31/4in. minimum into

room and must be 31/4in. minimum to 51/2in.

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.

IMPORTANT: Insulated Polymer Wall sleeve pro-

vides superior sound absorption, reduces heat loss

and prevents sleeve sweating.

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.

Outdoor Grille Selection

The following guidelines must be followed in the ini-

tial selection of any alternate exterior grille or louver:

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.

Hardwire Kit

Part No.: HARDWIRE-KIT-1PK

This accessory hardwire kit provides a permanent con-

nection to the unit. Electrical hard wiring is required

IF YOUR AIR CONDITIONER DOES NOT WORK, FOLLOW THESE STEPS IN ORDER:

1. CHECK THE THINGS YOU CAN DO YOURSELF. These include

being sure the air conditioner is plugged in firmly in an appropriate

receptacle, checking the fuse or circuit breaker and ensuring its re-

placement or resetting, if necessary, and rereading the instruction

book to ensure that all controls are set properly. By doing this you

can save money. Many unnecessary service calls result in the

serviceman doing what the owner can do for him or herself.

2. CONTACT YOUR DEALER OR THE RECOMMENDED

CARRIER AUTHORIZED SERVICE CENTER. They have been set up

to handle the great majority of all possible service problems. The

quickest, surest and best way to get your air conditioner back in

service is to use this step before proceeding further.

3. CONTACT THE CARRIER DISTRIBUTOR SERVING YOUR AREA.

Your dealer can provide the distributor’s name or you can consult your

yellow pages.

4. CONTACT CARRIER IF A SATISFACTORY SOLUTION IS NOT

REACHED IN STEPS 2 AND 3.
