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).
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 comprehensive 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 nonrefrigeration system parts.

APPLICATIONS (cont)
APPLICATION
CONSIDERATIONS

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 temperature too quickly.
The unit will cycle on and off, however, dehumidification 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.

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.

Air Infiltration
Excessive air infiltration can intensify problems associated with undersizing or oversizing a PTAC unit.
This can be the cause of insufficient cooling, dehumidification, or heating. Sources of air infiltration include
vents, gaps around windows and doors, and improperly 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 temperature during very hot days. The result could be
warm and humid or warm and dry conditioned space.

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
PERFORMANCE
High EERs provide excellent operating economy. The
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. The fan motor requires no
maintenance and no lubrication.

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.

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 requirements of Underwriters’ Laboratories and resists damage 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, provide 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.

HIDDEN CONTROLS

Fan Cycle Switch

The factory-wired control box houses all control components 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 components. The wiring diagram is located on the front of the
control box door.

The fan cycle switch allows the fan to operate in
2 modes:
• Continuous — This setting allows the fan to run
continuously, circulating air even when the temperature 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 variations 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 temperatures 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 testing 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 patented 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 evaporates, thus providing better disposal of excess condensate, improving unit efficiency.
NOTE: If it is necessary to remove 100% of the condensate, the Carrier Drain Kit (Part No.: DRAIN-KIT4PK) is recommended.

PRODUCT FEATURES AND BENEFITS (cont)
HEAT PUMPS PAY THEIR
OWN WAY

How The Heat Pump Works

Heat pump models are available at a nominal additional cost. In many locales, the payback is realized in
just a few months. Cost and payback details are provided on the next page.

Special Features
Two-Stage Indoor Thermostat:
In Hot Weather:

The indoor thermostat senses the indoor temperature
and automatically turns on the electric heat to warm
the room quickly. After the desired temperature conditions have been satisfied, the thermostat automatically
switches to heat pump mode. If compressor failure
occurs, the thermostat will provide backup electric
heat automatically.

Carrier’s PTAC units provide indoor comfort in the
same manner as conventional air conditioners, removing heat and humidity from indoor air. The heat and
humidity is released to the outdoors. Carrier’s highefficiency 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 temperature). 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 functions 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 cooling 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 produced, 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 operating 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.
Use the map to identify the climate
zone’s designated number. Reading
down the left-hand column of the
table, select the cost/kWh rate in
this zone that most closely approximates your local rate. The approximated savings and payback period
is found at the intersection of your
zone/rate line and the desired Btuh
Cooling Capacity column. Exact
savings are determined by lifestyle,
local electrical rates, and climatic
conditions.

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.

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.

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, including 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 31/4 in. minimum into
room and must be 31/4 in. minimum to 51/2 in.
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 fieldsupplied 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 provides superior sound absorption, reduces heat loss
and prevents sleeve sweating.

Outdoor Grille Selection
IMPORTANT: If you wish to use a grille not
made by Carrier for your Carrier unit(s), contact the Carrier Application Engineering Group
at 1-800-894-6449.

The following guidelines must be followed in the initial 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, baffles, 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.

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.

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 replacement 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.

4. CONTACT CARRIER IF A SATISFACTORY SOLUTION IS NOT
REACHED IN STEPS 2 AND 3.
