UNIT INSPECTION
Examine unit for damage incurred during shipment.
File a claim immediately with the transit company if
damage is found.
The data information plate (Figure 1) lists the model
number, voltage ranges, and other important electrical
information about this product. Reading and understanding this material is important for proper use of
this unit. To access the information plate, the front
panel must be removed; see Figure 2.
FRONT PANEL
To remove the front panel:
1. Grasp panel firmly near bottom of both sides.
2. Pull panel forward then upward to release magnetic latches and partition hooks.
NOTE: Front panel may be secured to chassi s wi th
2 screws located behind indoor air inlet filters. In order
to remove these screws, the filters must be removed
first. Refer to page 10 in this manual for instructions on
removing indoo r air in l et fi lt er s.
IMPORTANT: The front panel has to be off the unit
to complete future checks and installation procedures. Do not reinstall front panel at t his time.
Using Figures 1 and 3 as reference, verify that the
packaged terminal product ordered will operate properly in your facility. If you do not understand the information given or have questions about the product,
please call your local dealer or distributor.

ELECTRICAL SHOCK HAZARD
DO NOT alter cord or plug, and DO NOT use an
extension cord. Personal injury or damage to the
unit may result.
Be sure that your outlet matches the appropriate
blade configuration of the supplied plug and that it is
within reach of the service cord. A hardwire kit is
available as an accessory to change cord-connected
units to hardwired units. (See Accessories table on
page 14.)
GROUNDING
■
— For safety and protection, the unit
is grounded through the service cord plug or through
separate ground wire provided on hardwired units. Be
sure that the branch circuit or general purpose outlet
is grounded.

CHASSIS INSTALLATION
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 sleeve s/
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 Corporation 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 deterioration before installing chassis.
If baffles are not installed properly, loss of performance and premature damage to the major components can result.

IMPORTANT: The gaskets comb ine with the sleeve
face to create a weather barrier. If the chassis is
installed in a non-Carrier sleeve, this weather barrier may not be effective.
Chassis weighs up to 150 lbs. For personal protection, seek help when lifting the unit. Lift unit by
holding unit basepan.

CARE AND MAINTENANCE
In order to maintain proper performance of your packaged 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 passages 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 condition s, more freq uent clean ing
of the unit may be required to ensure optimum performance and long operating life. Examples of these special conditions include areas where construction dust
or heavy airborne dirt is found, or environments that
promote the growth of fungus.
Some local conditions and environments can cause
fungi to grow inside the air conditioner, especially
on indoor blower section. Dried fungi, dirt and ot her
foreign material are fire hazards. Be sure to clean
unit according to the instructions that follow.

should be cleaned
FIGURE 17 — INDOOR-AIR INLET
FILTER REMOVAL
IMPORTANT: Filters may become clogged if not
cleaned properly. Clogged filters will restrict airflow which may lead to severe component damage
and efficiency loss.
CLEANING INDOOR-AIR INLET FILTER
■
interchangeable air filters are located on the bac kside
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.

PREVENTATIVE
MAINTENANCE
Preventative maintenance is essential to proper unit
operation, efficiency and longevity. To assure equipment operates properly it must be properly maintained. Equipment operation should be checked and
verified several times during each year.
During regular unit inspection and maintenance, fo llow the guidelines below:
• Wash both sides of outdoor coil
• Wash base pan and outdoor vent filter
• Wash the indoor coil
• Clean the blow er wheel and front panel
• Clean or install new indoor-air inlet filter(s)
• Ensure knobs are secure and operable
• Inspect cord and receptacle
• Secure electrical connections
• Ensure front panel is properl y mounted and not
damaged
• Ensure wall sleeve is installed properly
• Ensure heat and cool cycles operate properly

•
Close vent door.
•
Clicking, gurgling and whooshing noises are normal during operation of
unit.
•
If a drain kit has not been installed, condensation run-off during
very hot and humid weather is normal. See Note 2. If a drain kit
has been installed and is connected to a drain system, check
gaskets and fittings around drain for leaks and plugs.
•
Wall sleeve must be installed level for proper drainage of condensation.
Check that installation is level and make any necessary adjustments.
•
When outdoor temperature is approximately 55 F or below, frost
may form on the indoor coil when unit is in Cooling mode. Switch
unit to FAN operation until ice or frost melts.
•
Remove and clean filters.
NOTES:
1. If circuit breaker is tripped or fuse is blown more than once, contact a qualified electrician.
2. If unit is installed where condensation drainage could drip in an undesirable location, an
accessory drain kit should be installed and connected to drain system.
