TEST RUNNING (Cont.)
20.3 STEPS FOR COOLING TEST RUNNING
a. Move circuit breaker to ON position.
b. Operate the system for cooling operation
at high fan speed by using wireless remote control.
c. After system operation becomes stabilized:
- Measure low pressure to check correct
refrigerant charge. (See figure & table )
- Measure total Amps consumed by the system.
- Measure System working voltage.
