Page 11: Location
6.1 LOCATION Do not install the indoor coil in the return duct system of a gas or oil furnace. Provide a service inlet to the coil for inspection and cleaning. Keep the coil pitched toward the drain connection. CAUTION When coil is installed over a finished ceiling and/or living area, it is recommended that a secondary sheet metal condensate pan be constructed and installed under entire unit. -

Page 15: Demand Defrost Control
8.0 DEMAND DEFROST CONTROL The demand defrost control is a printed circuit board assembly consisting of solid state control devices with electro-mechanical outputs. The demand defrost control monitors the outdoor ambient temperature, outdoor coil temperature, and the com- pressor run-time to determine when a defrost cycle is required. 8.1 DEFROST INITIATION A defrost will be initiated when the three conditions below are satisfied: 1) The outdoor coil temperature is below 35°F. -
Page 16: Test Mode
8.4 TEST MODE The test mode is initiated by shorting the TEST pins. In this mode of operation, the enable temperature is ignored and all timers are sped up by a factor of 240. To initi- ate a manual defrost, short the TEST pins. Remove the short when the system switches to defrost mode. -
Page 17: Start Up & Performance
10.0 START UP AND PERFORMANCE Even though the unit is factory charged with Refrigerant-22, the charge must be checked to the charge table attached to the service panel and adjusted, if required. (See Table 1). Allow a minimum of 5 minutes running. Before analyzing charge, see the instructions on the unit service panel rating plate for marking the total charge. -
Page 18: Charging By Weight
12.2 CHARGING BY WEIGHT For a new installation, evacuation of interconnecting tubing and indoor coil is ade- quate; otherwise, evacuate the entire system. Use the factory charge shown in Table 1 of these instructions or unit data plate. Note that charge value includes charge required for 15 ft. -

14.0 FIELD INSTALLED ACCESSORIES 14.1 COMPRESSOR CRANKCASE HEATER (CCH) While scroll compressors usually do not require crankcase heaters, there are instances when a heater should be added. Refrigerant migration during the off cycle can result in a noisy start up. Add a crankcase heater to minimize refrigeration migration, and to help eliminate any start up noise or bearing “wash out.”... -
