Resumen del manual
Even if pressure fall-back below the reset point of 295 psi, the error will not clear and the machine will not restart. Note: Split Systems do not have a High pressure sensor on the evaporator module. DRAIN CLOG: The drain clog sensor, located in the plastic drain pan behind the drain solenoid, will detect the presence of water just below the top edge of the pan. If water does not properly flow out of the drain pan it will rise to the sensor, especially during a self-flushing purge cycle. LO WATER: 1. There is a sensor in the water reservoir that reaches down to the very bottom. The machine will not start if water is not present at this sensor. 2. A hard error will occur should water not be present within 60 seconds of power up or if the sensors are disconnected or damaged. Relay output indication: Each relay on the board has an indicator light associated with its output. For example, when the relay for the water feed solenoid is energized, the adjacent indicator light glows green. Comp/Sol output: The output for the compressor is labeled COMP/SOL. For split systems, where the condensing unit is mounted remotely from the evaporator module, the COMP/SOL output is wired to the refrigerant solenoid. 15 Wiring diagram #15 4 801 CHURCH LANEEASTON, PA 18040, USA800-523-9361 OR 610-252-7301FOR SERVICE CALL: ON THE WEB: JUMPER 16 Compressor data Compressor current draw Air-cooled Ambient air temp. 60°F/16°C 6.4A Water-cooled Condenser water temp 50°F/10°C 70°F/21°C 6.4A 60°F/16°C 80°F/27°C 6.8A 70°F/21°C 90°F/32°C 7.4A 80°F/27°C 100°F/38°C 7.6A 90°F/32°C 6.5A 6.6A 6.8A 7.3A 7.5A Locked rotor amps 54 Gearmotor data Brother Gearmotor current 2.8A (nominal) Locked rotor amps 15 amps Resistance of windings 208-230 vac gearmotor (Brother) 6.2.
