20. TEST RUNNING
20.1 NOTES
-
Operate testing running after completion of connecting refrigerant piping lines,
drain line and electrical wiring and refrigerant leak test.
-
Operate test running after mounting air filters, and front panel of indoor unit.
20.2 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.
