42TEST RUNNING (Cont.)19.4 STEPS FOR HEATING TEST RUNNINGa. Move circuit breaker to ON position.b. After system operation becomes stabilized:- Measure high and low pressures to checkcorrect refrigerant charge. (See figure)- Measure total Amps consumed by the system.- Measure system-working voltage.System Heating Test RunningSYSTEM MODEL 53QG18-H 53QG24-HAMBIENT TEMP ºC 7 7HIGH PRESSURE PSI 240 260LOW PRESSURE PSI 52 50TOTAL AMPS 8.5 11.8Notes:1- Readings at 220 volt and 20 ºC return air to indoor unitand high speed of indoor unit motor.2- System with Standard mild ambient outdoor unit with rotary compressor.SYSTEM MODEL 53QG18-H 53QG24-HAMBIENT TEMP ºC 7 7HIGH PRESSURE PSI 230 250LOW PRESSURE PSI 60 60TOTAL AMPS 7.5 11.3Notes:1- Readings at 220 volt and 20 ºC return air to indoor unitand high speed of indoor unit motor.2- System with High ambient outdoor unit with rotary compressor.1.
