INSTALLATION

CHASSIS INSTALLATION

Units are shipped without a sleeve. In applications where unit is a replacement, it is recommended that a Carrier sleeve and grille be used.

The 52C and 52P units can retrofit General Electric, Amana, Trane, and Friedrich sleeves/grilles (be sure outdoor grille is installed on the sleeve). See Table 3 for details. Carrier Corporation must approve any other retrofit application.

For competitive retrofit applications, be sure that the foam seals (factory- installed on the tube sheets) provide a good seal between the outdoor grille and outdoor coil tube sheets. These foam seals provide a barrier to separate outdoor coil leaving air from mixing with the outdoor incoming air (knov, m_as air recirculation). See Figure 5.

CAUTION

For retrofit applications, foam seals on outdoor coil tube sheets must make a seal between the coil and the grille or loss of performance and premature damage to the major components can result.

FIGURE 5 — UNIT COMPONENTS

COMPETITIVE SLEEVE PREPARATION

IMPORTANT: Inspect the wall sleeve thoroughly prior to installation. Manufacturer does not assume responsibility for costs or damages due to defects in the sleeve or improper installation.

WARNING
Disconnect all power to unit to avoid possible electrical shock during installation.

Remove any existing foam baffles that are installed on the outdoor grille ff present. See Figure 6.

GE Sleeves Only
Metal Wall Sleeve — Remove metal clip on mounting rail located on left, inside bottom of metal sleeve and discard. See Figure 7.

Plastic Sleeve — Remove bottom seal from plastic sleeve. See Figure 8.

INSTALLATION OF A CARRIER WALL SLEEVEUSING A NON-CARRIER GRILLE
This application has become more common due to pre-manufactured windows with built-in grilles or renovations where a Carrier sleeve is used with an existhag non Carrier grille.

Use of a Carrier wall sleeve with a non-Carrier grille requires installation of an Accessory Baffle Kit, which ensures a good seal between the unit and exterior grille and prevents air recirculation. ( **See Figures 9 and 10.)

**
Air recirculation is a large contributor to performance loss and premature damage to major components.

INSTALL CHASSIS IN SLEEVE (See Figures 11to 13)

1. Inspect foam gaskets (top, bottom, both sides) on chassis. Replace foam gaskets ff 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 barrier may not be effective.
   WARNING Chassis weighs up to 150 lb, For personal protection, seek help when lifting the unit. Lift unit by holding unit baseman.

2. If retrofitting into a GE, Amana, Trane, or Friedrich wall sleeve/grille, remove any existing foam seals from competitive manufacturer s grille before installing unit.

3. Remove shipping tape from vent door. See Figure 11.
   
   CAUTION Failure to remove shipping tape will prevent fresh air vent door from opening and may result in damage_ to the vent door cable.

4. Carefully remove power cord packing material and discard.

5. Lift chassis level with wall sleeve.

6. Slide chassis into wall sleeve until foam gaskets rest firmly against front of wall sleeve. See Figure 12.
   

7. Screw chassis to wall sleeve with four 13/tin. long screws taped to the control box. Screw holes are located on both sides of the mounting angles of the chassis. For Carrier wall sleeves, use the top-mast and bottom-most screw holes, For competitive wall sleeves, line up the correct attachment holes on the chassis with the holes in the sleeves. See **Figure 13.

**

WALL THERMOSTAT INSTALLATION

The following instructions apply to RC and laP units only.

NOTE: Carrier thermostats are recommended. See Accessories section.

IMPORTANT: Only trained, qualified personnel and service mechanics should install electrical accessories on Carrier 52C and 52P series products per Carrier’s installation instructions. Please contact your local electrical contractor, dealer, or distributor for assistance.

THERMOSTAT WIRE ROUTING — Thermostat
wire is field supplied. Recommended wire gage is 18 to 20 gage solid thermostat wire. Thermostat wire should always be routed around or under, NEVER through, the wall sleeve. The wire should then be routed behind the front panel to the easily accessible terminal connector. See Figures 14 and 15.

INSTALL THERMOSTAT — All remote control units.

1. Check to be sure power to unit is disconnected.

2. Pull terminal connector to remove.
   NOTE: Terminal connector can be removed and replaced to simplify thermostat wiring.

3. Connect wires from terminals on the thermostat to terminals on chassis terminal board connector. See **Figures 15 and 16.

5. Restore power to unit.
   NOTE: Refer to thermostat installation instructions for details on installing thermostat.
   NOTE: Fan speed is user selectable from the control panel on the unit.

NOTES:

1. Use terminal “O” for heat pump connection only.
2. Terminal C (common) Typically only required for digital thermostats
3. See table below for terminal descriptions,

OPERATION

IMPORTANT: When unit is first started, high humidity conditions can cause condensation to form on discharge grille. Keep doors and windows closed.
Room humidity decreases and moisture evaporates.

COMFORT CONTROLS

• ADJUST AIRFLOW DIRECTION — The discharge air grille is mounted on the front panel so that the air discharges forward. If upward discharge is required, remove the grille by removing screws on back of front panel. Rotate grille 180 degrees and reinstall on the front panel.

• ADJUST VENT — The vent handle is on the left side of the unit. Turn handle to open or close vent. Vent will remain in last desired position until handle  is turned again. Magnet will ensure positive closure . See Figure 17.
  

• SETTING TEMPERATURE LIMITS — Setting temperature limits on the unit provides the user a restricted range of temperature control. See Figure 18.
  
  NOTE: This adjustment is optional and is not applicable to remote control units.

The temperature limits are factory set to full range, which is 60 F to 90 F. To set restricted rotation of the temperature control knob:

1. Remove front panel.
2. Remove temperature control knob to expose temperature limiter.
3. Remove standoff pins from the 60 F and 90 F indicator holes.
4. Replace standoff pin in bole for desired minimum temperature.
5. Replace standoffpin in hole for desired maximum temperature.
6. Reinstall temperature control knob.
7. Reinstall front panel.
   NOTE: Temperature indicators stamped on temperature limiter are approximate and represent degrees E

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 18.

• FAN CYCLE SWITCH — (Typically available at wall thermostat 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 temperature setting has been satisfied. This switch helps to maintain the room temperature closer to the ther* mostat setting. Use this switch position when maximum comfort is desired. This is the factory default setting.
  CY_C C(vcle) — This setting allows the fan to cycle on off with the compressor during heating or cooling. The fan stops when the temperature setting is satisfied. This results in longer unit off-time and wider variations in room temperature and humidity.

• 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 Figure 18. When the temperature of the outdoor coil reaches 20 F (approximately 35 F outdoor air temperature), the compressor will shut down as unit is no longer capable of adequate heating in heat pump mode. The electric heater then becomes the primary heating source. The electric heater remains on until the temperature of the outdoor coil reaches 40 F; then the electric heater is shut off and the compressor is energized. Once the compressor is energized, the heat pump again becomes the primary heating source. To set unit to operate in electric heat mode only, turn the setscrew to the electric heat position. S ee Figure 18.

IMPORTANT: If setscrew on standard heat pump unit is set to electric heat mode operation, the compressor 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.

OPERATING MODES (See Figures 19 and g0.)

• OUTSIDE AIR — To bring outside air into occupied space, turn the vent handle to the full open position. See Figure 17.
• 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.
• 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.
• FAN SPEED CONTROL FOR 52P AND 52C WALL THERMOSTAT MODELS — For maximum comfort, fan speed is user selectable at the unit. **See Figure 20

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 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 conditions, more frequent cleaning 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.

CAUTION 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 airflow 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 5 and 21.
   

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 residue 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.

EXTERNAL PARTS

• EXTERNAL PARTS include the polymer sleeve and grilles. The sleeve manufacturer recommends cleaning the surface, including the grilles, with household detergent and water.

INTERNAL PARTS

• INTERNAL PARTS should be cleaned at least once during the year. The outdoor vent triter should be cleaned at least once during a cooling or heating season.

**Internal parts that should be cleaned include the following (see Figures 5, 22, and 23):

**

• Outdoor vent filter
