Conventional defrost time adjustment
(CRTD)
The conventional defrost is adjusted based
upon compressor run time between defrost
cycles (CRTD). This time can be adjusted
from between 4 hours (minimum) to 24 hours
(maximum) in one hour increments.
Conventional defrost must first be selected as
shown in previous step.
Even though the All Refrigerator doesn't
have a defrost system, the board can
still be programmed. The unit can be set
to conventional defrost in high humidity
areas and set for every 6 hours of CRTD.
This will cut down on frost issues.
