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 9: Replacement Units
FIGURE 2 TIE-DOWN KIT ASSEMBLY DETAIL A REPLACEMENT UNITS To prevent failure of a new condensing unit, the existing evaporator tubing system must be correctly sized and cleaned or replaced. Care must be exercised that the expansion device is not plugged. Test the oil for acid. If positive, a suction line filter drier is mandatory. - Page 10 OUTDOOR UNIT INSTALLED ABOVE INDOOR COIL Keep the vertical separation between coils to a minimum. However, the vertical dis- tance can be as great as 120 feet with the condensing unit ABOVE the indoor coil. Use the following guidelines when installing the unit: DO NOT exceed 120 feet maximum vertical separation.

Page 13: Evacuation Procedure
EVACUATION PROCEDURE Evacuation is the most important part of the entire service procedure. The life and efficiency of the equipment is dependent upon the thoroughness exercised by the serviceman when evacuating air and moisture from the line set and indoor coil. Air in the system causes high condensing temperatures and pressure, resulting in increased power input and non-verifiable performance. -
Page 14: Checking Refrigerant Charge
Electric resistance heaters can use volts x amps x 3.414 CFM = 1.08 x temp rise Gas furnaces can use BTUH CFM = ΔT x 1.08 An air velocity meter or airflow hood can give a more accurate reading of the sys- tem CFM. -

LOW AMBIENT CONTROL (LAC) This component senses compressor head pressure and shuts the condenser fan off when the head pressure drops to approximately 175 PSIG. This allows the unit to build a sufficient head pressure at lower ambient in order to maintain system bal- ance and obtain improved capacity. -
