This refrigeration unit has following functions.
(1) Defrosting operation function
This is the function to protect evaporator from frosting during cooling
operation and to prevent refrigerating power from decreasing.
There are following 2 methods to start defrosting operation.
1) Automatic defrosting operation
Defrosting starts automatically by the timer setting.
Refer to page 29 for defrosting timer setting.
2) Manual defrosting operation
Defrosting starts forcibly by pressing the switch of controller.
Refer to page 37 for how to operate.
As the defrosting operation is completed, the refrigeration unit returns to
the cooling operation.
Defrosting operation will not start when the evaporator temperature is
high even during the cooling operation
(2) Timer operation function
This is the function to set starting time and stopping time of the
operation .
Refer to pages from 38 to 41 for how to set.
