19. TEST RUNNING
19.1 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 wiring
19.2 STEPS FOR COOLING TEST RUNNING
a. Move circuit breaker to ON position.
b. After system operation becomes stabilized:
-
Measure high and low pressures to check
correct refrigerant charge. (See figure & table)
-
Measure total Amps consumed by the system.
-
Measure System working voltage.
