CERTIFICATION: All models are listed with UL, (U.S. and Canada), AHRI, and CEC. ELECTRICAL RANGE: Units offered in single phase 208/230v are 018--060, and three phase 208/230v in 036, 048 and 060. FAN MOTOR: The totally enclosed fan motor provides greater reliability under adverse conditions and dependable performance for many years. The permanent split capacitor type motor was designed for optimum efficiency. The motor was then qualified under extreme conditions to help ensure a long, reliable life. CABINET: A weather protective cabinet of prepainted steel is protected underneath by a galvanized coating and treated with a layer of zinc phosphate for a finish that will last for many years. All screws on cabinet exterior are coated for a long--lasting, rust--resistant, quality appearance. UNIT DESIGN: The copper tube, enhanced sine wave, aluminum fin coil is designed for optimum heat transfer. Vertical air discharge carries sound and hot condenser air up and away from adjacent patio areas and foliage. The base pan is designed for easy removal of water, dirt, and leaves. COMPRESSOR: Each compressor is protected with internal temperature-- and current--sensitive overloads. An internal pressure relief valve provides high pressure protection to the refrigerant system. For improved serviceability, all models are equipped with a compressor terminal plug. SERVICE VALVES: Both service valves are brass, front seating type with sweat connections. Valves are externally located so refrigerant tube connections can be made quickly and easily. Each valve has a service port for ease of checking operating refrigerant pressures. SERVICEABILITY: One access panel provides access to electrical controls. Removal of top gives access to fan motor, compressor, and condenser coil.

The factory charge for 3/8â€ lineset 9 oz. When using other length or diameter liquid lines, charge adjustments are required per the chart above. Charging Formula: [(Lineset oz/ft x total length) â€“ (factory charge for lineset)] = charge adjustment Example 1: System has 15 ft of line set using existing 1/4â€œ liquid line. What charge adjustment is required? Formula: (.27 oz/ft x 15ft) â€“ (9 oz) = (-4.95) oz. Net result is to remove 4.95 oz of refrigerant from the system Example 2: System has 45 ft of existing 5/16â€ liquid line. What is the charge adjustment? Formula: (.40 oz/ft. x 45ft) â€“ (9 oz.) = 9 oz. Net result is to add 9 oz of refrigerant to the system LONG LINE APPLICATIONS An application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintain acceptable refrigerant management for systems reliability. See Accessory Usage Guideline table for required accessories. Defining a system as long line depends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor and outdoor units. For Air Conditioner systems, the chart below shows when an application is considered Long Line.

In most cases, only 1 method should be used to achieve TDR function. Using more than 1 method in a system may cause degradation in performance. Use either the accessory Time---Delay Relay KAATD0101TDR or a furnace equipped with TDR. Most Payne furnaces are equipped with TDR. NOTES: 1. Ratings are net values reflecting the effects of circulating fan motor heat. Supplemental electric heat is not included. 2. Tested outdoor/indoor combinations have been tested in accordance with DOE test procedures for central air conditioners. Ratings for other combinations are determined under DOE computer simulation procedures. 3. Determine actual CFM values obtainable for your system by referring to fan performance data in fan coil or furnace coil literature. PA13NA / PA13PA4.

CERTIFICATION: All models are listed with UL, (U.S. and Canada), AHRI, and CEC. ELECTRICAL RANGE: Units offered in single phase 208/230v are 018--060, and three phase 208/230v in 036, 048 and 060. FAN MOTOR: The totally enclosed fan motor provides greater reliability under adverse conditions and dependable performance for many years. The permanent split capacitor type motor was designed for optimum efficiency. The motor was then qualified under extreme conditions to help ensure a long, reliable life. CABINET: A weather protective cabinet of prepainted steel is protected underneath by a galvanized coating and treated with a layer of zinc phosphate for a finish that will last for many years. All screws on cabinet exterior are coated for a long--lasting, rust--resistant, quality appearance. UNIT DESIGN: The copper tube, enhanced sine wave, aluminum fin coil is designed for optimum heat transfer. Vertical air discharge carries sound and hot condenser air up and away from adjacent patio areas and foliage. The base pan is designed for easy removal of water, dirt, and leaves. COMPRESSOR: Each compressor is protected with internal temperature-- and current--sensitive overloads. An internal pressure relief valve provides high pressure protection to the refrigerant system. For improved serviceability, all models are equipped with a compressor terminal plug. SERVICE VALVES: Both service valves are brass, front seating type with sweat connections. Valves are externally located so refrigerant tube connections can be made quickly and easily. Each valve has a service port for ease of checking operating refrigerant pressures. SERVICEABILITY: One access panel provides access to electrical controls. Removal of top gives access to fan motor, compressor, and condenser coil.

The factory charge for 3/8â€ lineset 9 oz. When using other length or diameter liquid lines, charge adjustments are required per the chart above. Charging Formula: [(Lineset oz/ft x total length) â€“ (factory charge for lineset)] = charge adjustment Example 1: System has 15 ft of line set using existing 1/4â€œ liquid line. What charge adjustment is required? Formula: (.27 oz/ft x 15ft) â€“ (9 oz) = (-4.95) oz. Net result is to remove 4.95 oz of refrigerant from the system Example 2: System has 45 ft of existing 5/16â€ liquid line. What is the charge adjustment? Formula: (.40 oz/ft. x 45ft) â€“ (9 oz.) = 9 oz. Net result is to add 9 oz of refrigerant to the system LONG LINE APPLICATIONS An application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintain acceptable refrigerant management for systems reliability. See Accessory Usage Guideline table for required accessories. Defining a system as long line depends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor and outdoor units. For Air Conditioner systems, the chart below shows when an application is considered Long Line.
