Units are shipped without a sleeve. In applications  
where unit is a replacement, it is recommended that a  
Carrier sleeve be used. The 52C and 52P units can  
retrofit General Electric, Amana and Trane sleeves/  
grilles (be sure outdoor grille is installed on the  
sleeve). A retrofit kit with instructions is included  
with every unit. See Table 3 for details. Carrier Corpo-  
ration must approve any other retrofit application. In  
deep-wall applications, if an existing grille is used on  
an outdoor wall opening, do not install an additional  
outdoor grille on unit sleeve.  
Be sure that the foam strips and/or baffles provide a  
good seal between the grille and condenser coil tube  
sheets. These foam strips or baffles provide a barrier  
to separate condenser air from the major components  
(compressor and fan motor). See Figures 5 to 8.  
NOTE: Inspect wall sleeve for any damage or deterio-  
ration before installing chassis.

1. Inspect foam gaskets (top, bottom, both sides) on  
chassis. Replace foam gaskets if torn or missing.  
IMPORTANT: The gaskets combine with the sleeve  
face to create a weather barrier. If the chassis is  
installed in a non-Carrier sleeve, this weather bar-  
rier may not be effective.  
Chassis weighs up to 150 lbs. For personal protec-  
tion, seek help when lifting the unit. Lift unit by  
holding unit basepan.

To set unit to operate in electric heat mode only, turn  
the setscrew to the electric heat position. See Fig. 14.  
OPERATING CONTROLS  
The following controls are located on the front of the  
control box door, under front panel. To obtain access to  
operating controls, remove the unit front panel as  
shown on page 2. See Figure 14.  
IMPORTANT: If setscrew on standard heat pump  
unit is set to electric heat mode operation, the com-  
pressor is disabled for both heating and cooling  
operations. If setscrew on heat pump unit with wall  
thermostat control is set to electric heat mode  
operation, the compressor will be disabled only for  
heating operation.  
FAN CYCLE SWITCH — (Not available on RC or RP  
units.) This allows the fan to operate in two modes:  
CON (Continuous) — This setting allows the fan to  
run continuously, circulating air even when the tem-  
perature setting has been satisfied. This switch helps  
to maintain the room temperature closer to the ther-  
mostat setting. Use this switch position when maxi-  
mum comfort is desired. This is the factory default  
setting.  
CYC (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 satis-  
fied. This results in longer unit off-time and wider  
variations in room temperature and humidity.  
OPERATING MODES (See F igu r es 15  
a n d 16.)  
OUTSIDE AIR — To bring outside air into occupied  
space, turn the vent handle to the full open position.  
See Figure 13.  
OFF — The OFF mode terminates unit operation.  
FAN— The FAN mode will circulate air in the space  
at high speed and at high or low speed for cooling only  
models.  
OUTDOOR THERMOSTAT (52CQ and 52PQ HEAT  
PUMP UNITS ONLY) — If the setscrew is left at the  
factory setting (in the heat pump position), the unit  
will operate in the reverse cycle heating mode. See  
Fig. 14. When the temperature of the outdoor coil  
reaches 20° F (approximately 35° F outdoor air tem-  
perature), the compressor will shut down. The electric  
heater remains on until the temperature of the out-  
door coil reaches 35° F (approximately 45° F outdoor  
air temperature); then the electric heater is shut off  
and the compressor is energized.  
HIGH HEAT OR HIGH COOL — Select mode and  
rotate temperature knob to desired comfort level. This  
function provides maximum heating or cooling, and is  
recommended to raise or lower the room temperature  
quickly.  
LOW HEAT OR LOW COOL — Select mode and  
rotate temperature knob to desired comfort level. This  
function provides minimum heating or cooling with  
maximum dehumidification and quietest operation.  
NOTE: 52C and 52P wall thermostat units have a  
blank plate. See Figure 16.

CARE AND MAINTENANCE  
In order to maintain proper performance of your pack-  
aged terminal air conditioner or heat pump, it is very  
important that the fan and outdoor coil, the blower  
wheel, blower scroll, electric heater, and all drain pas-  
sages are thoroughly cleaned at least once per year.  
Carrier recommends that as a minimum, the cleaning  
should be conducted prior to the start of each heating  
season. The air inlet filters should be cleaned every  
month.  
Depending on local conditions, more frequent cleaning  
of the unit may be required to ensure optimum perfor-  
mance and long operating life. Examples of these spe-  
cial conditions include areas where construction dust  
or heavy airborne dirt is found, or environments that  
promote the growth of fungus.  
FIGURE 17 — INDOOR-AIR INLET  
FILTER REMOVAL  
Some local conditions and environments can cause  
fungi to grow inside the air conditioner, especially  
on indoor blower section. Dried fungi, dirt and other  
foreign material are fire hazards. Be sure to clean  
unit according to the instructions that follow.  
INDOOR-AIR INLET FILTERS  
INDOOR-AIR INLET FILTERS should be cleaned  
once each month.  
IMPORTANT: Filters may become clogged if not  
cleaned properly. Clogged filters will restrict air-  
flow which may lead to severe component damage  
and efficiency loss.  
CLEANING INDOOR-AIR INLET FILTER — Two  
interchangeable air filters are located on the backside  
of the front panel. Each can be removed and cleaned  
one at a time. To remove and clean the filter, follow  
the steps below:  
1. Grasp filter with both hands.  
2. Gently pull the filter up and away from the unit.  
See Figures 6 and 17.  
3. To clean filter, use a vacuum or soft bristle brush  
with a small amount of mild detergent.  
NOTE: If detergent is used, remove any detergent  
residual with a gentle stream of clean water.  
4. Allow filters to air dry.  
5. Re-insert dry filters back into front panel.  
Additional filters are available in multi-packs. Refer to  
Accessories section.
