Haier MRV5-H - Rated Operation; Trial Operation Confirmation

79
Startup control on indoor and outdoor units and operation condition inspection for outdoor units can be completed
through rated operation. In case of inspection on single indoor unit, wired controller or remote controller of indoor
unit will be adopted for control.
Rated cooling operation: when SW1, SW2 and SW3 dip switches are turned to 0, 13, 2, the indoor units will be
started up automatically and be forced to turn to cooling operation.
Rated heating operation: when SW1, SW2 and SW3 dip switches are turned to 0, 14, 2, the indoor units will be
started up automatically and be forced to turn to heating operation.
The test run conrmation, in principle, shows that all the indoor units should be conrmed one by one. Improper
connection of refrigeration lines and control wires cannot be conrmed when all the indoor units are running
simultaneously so all the other indoor units should be set in "stopped condition".
