The factory charge for 3/8” lineset 9 oz. (266.16 g). When using other length or diameter liquid lines, charge adjustments are required per the chart above. Charging Formula: [(Lineset oz/ft X total length) – (factory charge for lineset)] = charge adjustment Example 1: System has 15 ft of lineset* using existing 1/4“ liquid line. What charge adjustment is required? Formula:(.27 oz/ft X 15ft) – (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 5/16” liquid line. What is the charge adjustment? Formula:(.40 oz/ft. X 45ft) – (9 oz.) = 9 oz. Net result is to add 9 oz of refrigerant to the system NOTE: Conditions must be favorable for charging by subcooling method. Indoor temperature must be 70°F to 80°F (21°C to 27°C), and outdoor temperature must be 70°F to 100°F (21°C to 38°C). If outside these conditions, adjust charge for long linesets by weigh-in method. * When applicable. Refer to Physical Data Table in this PD and to the Installation Instructions for more information. Long Line Applications An application is considered "Long Line" when the total equivalent tubing length exceeds 80 ft or when there is more than 35 ft. vertical separation between indoor and outdoor units. These applications require additional accessories and system modifications for reliable system operation. The maximum allowable total equivalent length is 250 ft. The maximum vertical separation is 200 ft. when outdoor unit is above indoor unit, and 80 ft. when the outdoor unit is below the indoor unit. Refer to Accessory Usage Guideline below for required accessories. See Long-Line Application Guideline for required piping and system modifications. Also, refer to table below for acceptable vapor tube diameters to minimize the cooling capacity loss. VAPOR LINE SIZING AND COOLING CAPACITY LOSS Acceptable vapor line diameters provide adequate oil return to the compressor while avoiding excessive capacity loss. The suction line diameters shown in the chart below are acceptable for AC systems with Puron Advance™ refrigerant: Table 3 – Refrigerant Charge Adjustments Liquid Line Size Puron Advance™ Charge oz/ft (g/m) 3/8 0.60 (17.74) (Factory charge for lineset = 9 oz / 266.16 g) 5/16 0.40 (11.83) 1/4 0.27 (7.98) Table 4 – Vapor Line Sizing and Cooling Capacity Losses — Puron Advance™ Refrigerant 1-Stage Air Conditioner Applications Unit Nominal Size (Btuh) Maximum Liquid Line Diameters (In.

Ball-Bearing Fan Motor A fan motor with ball bearings which permits speed reduction while maintaining bearing lubrication. Usage Guideline: Required on all units when MotorMasterr is used. 2. Compressor Start Assist - Capacitor and Relay Start capacitor and relay gives a ”hard” boost to compressor motor at each start up. Usage Guideline: Required for single-phase scroll compressors in the following applications: Long line Low ambient cooling Suggested for all compressors in areas with a history of low voltage problems. 3. Crankcase Heater An electric resistance heater which mounts to the base of the compressor to keep the lubricant warm during off cycles. Improves compressor lubrication on restart and minimizes the chance of liquid slugging. Usage Guideline: Required in low ambient cooling applications. Required in long line applications. Suggested in all commercial applications. 4. Cycle Protector The cycle protector is designed to prevent compressor short cycling. This control provides an approximate 5-minute delay after power to the compressor has been interrupted for any reason, including power outage, protector control trip, thermostat jiggling, or normal cycling. 5. Evaporator Freeze Thermostat An SPST temperature-actuated switch that stops unit operation when evaporator reaches freeze-up conditions. Usage Guideline: Required when low ambient kit has been added. 6. Low-Ambient Pressure Switch Kit A long life pressure switch which is mounted to outdoor unit service valve. It is designed to cycle the outdoor fan motor in order to maintain head pressure within normal operating limits (approximately 100 psig to 225 psig). The control will maintain working head pressure at low-ambient temperatures down to 0_F (-18_C) when properly installed and also using wind baffles. Instructions provided in accessory kit. Usage Guideline: A Low-Ambient Pressure Switch or MotorMasterr Low-Ambient Controller must be used when cooling operation is used at outdoor temperatures below 55_F (12.8_C). 7. MotorMasterr Low-Ambient Controller A fan-speed control device activated by a temperature sensor, designed to control condenser fan motor speed in response to the saturated, condensing temperature during operation in cooling mode only. For outdoor temperatures down to –10°F/–23.3°C), it maintains condensing temperature at 100_F ±10_F (37.8_C ±5.5_C). Usage Guideline: A MotorMasterr Low Ambient Controller or Low-Ambient Pressure Switch must be used when cooling operation is used at outdoor temperatures below 55_F (12.8_C). Suggested for all commercial applications. 8. Sound Blanket Wraparound sound reducing cover for the compressor. Reduces the sound level of the compressor. Usage Guideline: Suggested when unit is installed closer than 15 ft (4.57 m) to quiet areas, bedrooms, etc. Suggested when unit is installed between two houses less than 10 ft (3 m) apart. ACCESSORY REQUIRED FOR LOW-AMBIENT COOLING APPLICATIONS (Below 55_F/12.8_C) REQUIRED FOR LONG LINE APPLICATIONS* *.For tubing set lengths between 80 and 200 ft. (24 and 61 m) horizontal or 35 ft. (10.7 m) vertical differential (total equivalent length), refer to the Residential Split-System Long Line Application Guideline.

No No 26SCA4: Product Data Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations. 8 Accessory Description and Usage (Listed Alphabetically) Continued 9. Support Feet Four or five stick-on plastic feet that raise the unit 4 in. (101.6 mm) above the mounting pad. This allows sand, dirt, and other debris to be flushed from the unit base, minimizing corrosion. Usage Guideline: Suggested in the following applications: Coastal installations. Windy areas or where debris is normally circulating. Rooftop installations. For improved sound ratings. 10. Time-Delay Relay An SPST delay relay which briefly continues operation of indoor blower motor to provide additional cooling after the compressor cycles off. NOTE: Most indoor unit controls include this feature. For those that do not, use the guideline below. Usage Guideline: For improved efficiency ratings for certain combinations of indoor and outdoor units. Refer to AHRI Directory of Certified Product Performance (AHRI Directory). When a Time-Delay Relay (TDR) is called for in the AHRI Directory, use a 30 second TDR for MicroChannel Indoor units and use a 90 second TDR for Round Tube Plate Fin Indoor units. 11. Winter Start Control This control is designed to alleviate nuisance opening of the low-pressure switch by bypassing it for the first 3 minutes of operation. 26SCA4: Product Data Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations. 9 AHRI RATINGS NOTE: Ratings contained in this document are subject to change at any time.
