Charge Refrigerant Lines

NOTE: Refrigerant lines must be charged by a licensed, EPA certified refrigeration technician in accordance with established procedures.

■

Adjustment of the refrigerant charge will be necessary based on the system combination and line length. To adjust the refrigerant size for increased line lengths, add the following amount of refrigerant.

The outdoor condensing unit should be charged during warm weather. However, applications arise in which charging must occur in the colder months. The method of charging is determined by the system’s refrigerant expansion device and the outdoor ambient temperature. Choose one of the following charge methods based on the system’s refrigerant expansion device and the outdoor ambient temperature.

Measure the Liquid Line Temperature and the Outdoor

Ambient Temperature

■

For line set lengths greater than 15 ft (4.6 m), add refrigerant by weighing in 0.60 oz per ft of

³⁄₈" (1 cm) O.D. liquid line.

If necessary, adjust the refrigerant charge for compatibility with the evaporator coil.

Charge Using Sub-cooling Method (Fixed Orifice/

Thermal Expansion Valve Systems)—Outdoor

Temperatures 65°F (18ºC) or Above

1. Connect the manifold gauge set to the service valve ports as follows:

■

Low pressure gauge to suction line service valve

Use this method if charging a fixed orifice or Thermal Expansion

Valve system when the outdoor ambient temperature is 65°F

(18ºC) or above.

■

High pressure gauge to liquid line service valve

1. Attach the manifold gauge hose to the liquid service port.

2. Close manifold gauge set valves.

3. Connect the center manifold hose to an upright cylinder of refrigerant (R-22).

2. If the condensing unit pressures are stable, use a digital thermometer to record the liquid line temperature.

3. Record the liquid line pressure reading.

4. If room temperature is below 70°F (21ºC), set the room thermostat to call for heat. This will create the necessary load for properly charging the system in the cooling cycle.

4. Use a temperature/pressure chart for refrigerant (R-22) to determine the saturation temperature for the liquid line pressure reading.

5. When the heating demand has been satisfied, switch the thermostat to cooling mode with a set point of 68°F.

5. Subtract the liquid line temperature from the saturation temperature to determine sub-cooling.

6. When pressures have stabilized, use a digital thermometer to record the liquid and suction line temperatures.

_____ ° (Saturation Temperature °F) - _____ ° (Liquid Line

Temperature °F) = _____ ° (Sub-cooling Value °F)

7. Use a digital thermometer to record the outdoor ambient temperature.

6. Compare the sub-cooling value: For W2C3 models—10ºF to

12ºF; for W2C4 models—8ºF to 10ºF.

NOTE: The outdoor temperature will determine which charging method to use.

■

If sub-cooling is greater than shown for your model, recover some refrigerant.

Charge Using Weigh-In Method (Fixed Orifice/Thermal

Expansion Valve Systems)

■

If sub-cooling is less than shown for your model, add some refrigerant.

Use this method if the system is void of refrigerant, or if the outdoor ambient temperature is cool.

1. Locate and repair any leaks.

2. If necessary, recover the refrigerant from the condensing unit.

3. Conduct a leak check, then evacuate as previously outlined.

4. Weigh in the charge according to the total amount shown on the condensing unit nameplate.

NOTE: If weighing facilities are not available or if the condensing unit is being charged during warm weather, follow one of the other charging methods.

IMPORTANT:

■

■

Refrigerant charge adjustment will be required for line set lengths greater than 15 ft (4.6 m) and for non systemmatched evaporator coils.

The condensing unit is factory-charged with the proper refrigerant charge amount for a matching evaporator and

15 ft (4.6 m) of refrigerant line. Refer to the condensing unit rating plate for the exact amount of this factory charge.

Charge Using Superheat Method (Fixed Orifice

Systems)—Outdoor Temperatures 65°F (18ºC) or Above

Use this method if charging a fixed orifice system when the outdoor ambient temperature is 65ºF (18ºC) or above.

1. Attach the manifold gauge hose to the suction service port.

2. If the condensing unit pressures are stable, use a digital thermometer to record the suction line temperature.

3. Record the suction line pressure reading.

4. Use a temperature/pressure chart for refrigerant (R-22) to determine the saturation temperature for the suction line pressure reading.

5. Subtract the saturation temperature from the suction line temperature to determine the superheat. See Superheat

Values for Fixed Orifice Systems chart.

_____ ° (Suction Line Temperature °F) - _____ ° (Saturation

Temperature °F) = _____ ° (Superheat Value °F)

6. Compare the superheat value with those shown in the chart located on the control box cover.

■

If superheat is greater than shown, add some refrigerant.

■

If superheat is less than shown, recover some refrigerant.

Complete Installation

1. Operate the condensing unit for a period of at least

15 minutes to allow for pressures and temperatures to stabilize.

2. If condensing unit does not appear to be functioning correctly, have condensing unit checked by a person certified by the EPA to handle refrigerant.

SEQUENCE OF OPERATION

Upon cooling demand, the thermostat closes circuit R to Y.

Closing R to Y energizes the condenser for cooling operation and closes the unit contactor, starting the compressor and outdoor fan. The thermostat automatically closes R to G circuit which also brings on the indoor fan at the same time.

Upon satisfying cooling demand, the thermostat will open the above circuits and open the main contactor, stopping the compressor and outdoor fan. If the indoor unit is equipped with a delay timer, the blower will continue to operate for 60 to

90 seconds, which improves system efficiency.

■

SYSTEM MAINTENANCE

Leaves and other large obstructions should be removed from the condensing unit surfaces without damaging the fin surface of the coil.

■

■

Routinely clean or change the indoor air filter. Should the indoor coil become dirty, thus restricting airflow, call a qualified service person to clean the coil surface.

An annual inspection by a qualified person should be performed to ensure continued high-quality performance.
