Time clocks
In the cabinets which have bottom-mounted condensing units, the time clock will be located along the
side of the unit. It will be readily visible when the motor cover is removed. The timer is set at the factory
for two defrost periods with a fail safe of 40 minutes for both single and multiple door cabinets. (For SAV
models the timer is set at the factory for four (4) defrost periods of 30 minutes.) Tests have shown that the
factory setting is satisfactory for most applications. However, changes can be made after a sufficient trial
period if necessary.
The fail safe is controlled by the small copper pointer on the inner dial. To reset the timer, grasp the
knurled knob and turn it counterclockwise until the pointer is at the correct time. As soon as the power is
turned on, if the temperature control is in the “on” position, the time clock and condensing unit will start.
When the coil temperature reaches the proper temperature, the fan(s) will automatically start and
continue to run until it comes to the defrost cycle. The fan(s) may turn off if the doors are left open too
long during a loading period and the coil becomes warm. Do not call for service until the freezer is given
enough time to come down to the proper temperature. After the unit is put into operation, the fan(s) will
continue to operate until the storage area reaches a proper temperature (recommended average 0
o
F).
The red pilot on the front of the top grill should turn off after about an hour of operation or whenever the
