System Functions And Sequence Of Operation The backdoor unit controls following is an overview of the Cooling Operation NATHAN and NATHAN (intuiting circuit board BEADLES or newer) models utilize either a 2-stage cooling dao thermostat or an Finely communicating User Inters With a call for first stage cooling, the outdoor slag Compressor are energized. If low-stage cannon satisfy cooling demand, high-stag is energized by the second stage of indoor thermostat or User Intel After second.
24ANA Compressor Operation on 24ANA1 Models The basic scroll design has been modified with the addition of an infernal unloading mechanism that opens a by-pass port in the First compression pocket, effectively reducing the displacement of the sonar The opening and closing of the by-pass part is controlled by an internal electrically operated solenoid. The modulated scroll uses a single step of unloading to go from full capacity to approximately 67% capacity.
Check Charge All 24ANA units must be charged in high stage only. Factory charge amount and desired sub cooling are shown on unit rating plate. Charging method is shown on information plate inside wit. To property check or adjust charge, conditions most be favorable for sub cooling charging. Favorable conditions exist when the outdoor temperature is between TO°F and 100°F s 1d the indoor temperature is between and Follow the procedure below Unit is factory charged for 15 ft (4.37 1} of TELNET.
