Page 7: Unit Mounting
UNIT MOUNTING If elevating the condensing unit, either on a flat roof or on a slab, observe the following guidelines. • The base pan provided elevates the condenser coil 3/4” above the base pad. • If elevating a unit on a flat roof, use 4” x 4” (or equivalent) stringers positioned to distribute unit weight evenly and prevent noise and vibration. -
Page 8: Refrigerant Connections
FIGURE 2 SCREW LOCATIONS REFRIGERANT CONNECTIONS All units are factory charged with Refrigerant 410A. All models are supplied with service valves. Keep tube ends sealed until connection is to be made to prevent system contamination. TOOLS REQUIRED FOR INSTALLING & SERVICING R-410A MODELS Manifold Sets: -Up to 800 PSIG High side... -
Page 9: Replacement Units
Physical Properties: R-410A has an atmospheric boiling point of -62.9°F and its saturation pressure at 77°F is 224.5 psig. Composition: R-410A is an azeotropic mixture of 50% by weight difluoromethane (HFC-32) and 50% by weight pentafluoroethane (HFC-125). Pressure: The pressure of R-410A is approximately 60% (1.6 times) greater than R-22. -
Page 10: Interconnecting Tubing
NOTE: All (-)ANL units must be installed with a TEV Evaporator. The thermostatic expansion valve is specifically designed to operate with R-410A. DO NOT use an R-22 TEV or evaporator. The existing evaporator must be replaced with the factory specified TEV evaporator specifically designed for R-410A. -
Page 11: Outdoor Unit Below Indoor Coil
Capillary Tube Coil: DO NOT exceed the Table values for vertical separation for capillary tube coils. Always use the smallest liquid line size permitted to minimize the system charge. Table 4 may be used for sizing horizontal runs. OUTDOOR UNIT BELOW INDOOR COIL Keep the vertical separation to a minimum. -
Page 12: Tubing Connections
TUBING CONNECTIONS Indoor evaporator coils have only a holding charge of dry nitrogen. Keep all tube ends sealed until connections are to be made. • Use type “L” copper refrigeration tubing. Braze the connections with the follow- ing alloys: – copper to copper - 5% –... -
Page 14: Leak Testing
LEAK TESTING • Pressurize line set and coil through service fittings with dry nitrogen to 150 psig maximum. Leak test all joints using liquid detergent. If a leak is found, recover pressure and repair. WARNING DO NOT USE OXYGEN TO PURGE LINES OR PRESSURIZE SYSTEM FOR LEAK TEST. -
Page 15: Checking Refrigerant Charge
The installers should balance the air distribution system to ensure proper quiet air- low to all rooms in the home. This ensures a comfortable living space. These simple mathematical formulas can be used to determine the CFM in a resi- dential or light commercial system. -
