4119. TEST RUNNING19.1 Note:- Operate test running after mounting air filters, return grill and cabinet.- Operate testing running after completion of connecting refrigerant piping lines,drain line and electrical wiring19.2 STEPS FOR COOLING 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 & table)- Measure total Amps consumed by the system.- Measure System working voltage.System Cooling Test RunningSYSTEM MODEL 53QG18-H 53QG24-HAMBIENT TEMP ºC 35 40 46 35 40 46 52HIGH PRESSURE PSI 280 315 350 260 305 345 390LOW PRESSURE PSI 72 75 79 60 62 64 66TOTAL AMPS 9.5 10.5 11.5 11.8 12.7 13.9 15.1Notes:1- Readings at 220 volt and 27 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 35 40 46 52 35 40 46 52HIGH PRESSURE PSI 280 312 343 392 267 300 334 382LOW PRESSURE PSI 73 75 77 79 65 67 69 71TOTAL AMPS 8.6 9.3 10.1 11.1 12.2 13.1 14.0 15.3Notes:1- Readings at 220 volt and 27 ºC return air to indoor unitand high speed of indoor unit motor.2- System with High ambient outdoor unit with rotary compressor.SYSTEM MODEL 53QG18-C 53QG24-CAMBIENT TEMP ºC 35 40 46 52 35 40 46 52HIGH PRESSURE PSI 260 295 330 370 260 297 335 375LOW PRESSURE PSI 69 71 73 75 62 64 66 68TOTAL AMPS 8.5 9.1 9.8 10.5 12.5 13.4 14.4 15.5Notes:1- Readings at 220 volt and 27 ºC return air to indoor unitand high speed of indoor unit motor.2- System with High ambient outdoor unit with rotary compressor.(1)1.
