Lateral Air Deflector
Part No.: DEFLECTOR-1PK
Carrier’s exclusive lateral air deflector allows dis-
charge air to be directed right or left in a room. This
field-installed accessory is equipped with indepen-
dently adjustable louvers to enhance air circulation.
Lateral air deflectors are recommended for units
mounted in a corner or off-center in a room.
NOTE: The lateral air deflector is not compatible with
previous PTAC models.
Curtain Deflector
Part No.: CURTDFL-52CP-1PK
The curtain deflector is used to prevent curtains from
being blown into the discharge air.
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.
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.
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 46.)
