it is important to have the proper balance between the air being supplied to each room and the air returning to the cooling and heating equipment. Proper balance and sealing of the duct system improves the efficiency of the heating and air conditioning system and improves the indoor air quality of the home by reducing the amount of airborne pollutants that enter homes from spaces where the ductwork and/or equipment is located. -

Page 11: Importance Of Proper Indoor/Outdoor Match-Ups
2.6 IMPORTANCE OF PROPER INDOOR/ OUTDOOR MATCH-UPS To assure many years of reliable operation and optimum customer comfort and to assure the outdoor unit warranty remains valid, an air-handler model should be selected that is properly matched to the outdoor unit. This is especially critical for heat pump systems to assure proper refrigerant charge balance between the cooling and heating modes. -
Page 12: Quick-Reference Guide For R-410A
Physical Properties: R-410A has an atmospheric boiling point of -62.9°F [-52.7°C] and its saturation pressure at 77°F [25°C] is 224.5 psig. Composition: R-410A is a near-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 13 FIGURE 4 DIMENSIONS FOR REFRIGERANT-TUBING & DRAIN CONNECTIONS VERTICAL AUXILIARY DRAIN CONNECTION HORIZONTAL AUXILIARY DRAIN CONNECTION GAS PIPE LIQUID PIPE MAIN DRAIN PIPE support rails installed at the factory should be left in place to help retain the cabinet insulation. They will be located on the warmer return side of the air-handler for down and horizontal right discharge applications and will therefore not pose a risk for cabinet sweating.

Page 14: Installation In An Unconditioned Space
IMPORTANT: To comply with certification agencies and the National Electric Code for down discharge applications, the circuit breaker(s) on field-installed electric heater kits must be re-installed per procedure below so that the breaker switch “on” position and marking is up and the “off” position and marking is down. 1. -

FIGURE 10 DUCT FLANGE INSTALLATION 3.6 DUCTWORK Field ductwork must comply with the National Fire Protection Association NFPA 90A, NFPA 90B and any applicable local ordinance. WARNING Do not, under any circumstances, connect return ductwork to any other heat producing device such as fireplace insert, stove, etc. Unauthorized use of such devices may result in fire, carbon monoxide poisoning, explo- sion, personal injury or property damage. -

of their useful life, the pressure drop through them increases. Therefore, it is important to factor the “end of life” (dirty) pressure drop of filters into the external static pressure of the duct system when selecting blower speeds and designing ductwork to assure the system is operating at the design CFM and system reliability is not compromised. -
Page 20: Evacuation
3.8.5 EVACUATION If no leaks are detected, evacuate the system down to 500 microns or below before charging the system or opening the service valves on the outdoor unit which will release the charge stored in the outdoor unit into the line set and air-handler coil. Failure to reach 500 microns of vacuum is a sign of a leak or excessive moisture inside the system. -
Page 21: Condensate Drain
FIGURE 13 CONDENSATE DRAIN TRAP ST-A1244-01-00 3.10 CONDENSATE DRAIN Consult local codes or ordinances for specific requirements. IMPORTANT: When making drain fitting connections to the drain pan, use a thin layer of Teflon paste, silicone or Teflon tape and install hand tight. IMPORTANT: When making drain fitting connections to drain pan, do not overtighten. -

3.13.2.3 (-)H2T MODELS (CONSTANT TORQUE ECM MOTOR) – SINGLE STAGE AIR-FLOW (-)H2T air-handlers may be matched to single stage outdoor units if properly configured. When using a single speed outdoor unit, Y1 and Y2 thermostat wires must connect to the Y2 (Yellow/Blue) wire on the air handler. For 1/2 tonnage outdoor units (1.5T, 2.5T and 3.5T) the blue wire from the control board should be connected to either T2 or T3 on the motor low voltage terminal block. -
