Condensate Water Removal
McCall cabinets are equipped with condensate vaporizer
systems.
Remote units use an electrically operated system.
Most self-contained units use either an energy-free
automatic type or an electrically-operated type. No drain
connection is required.
Defrost Systems
GENERAL
Refrigerator coils are kept below the freezing point
(32
°F). During compressor off time, the evaporator fan
continues to circulate 38
°F refrigerator compartment air
through the evaporator coil. This air circulation raises the
coil temperature above the freezing point, melting any
accumulated frost. The run-off water is drained into the
vaporizer pan and is evaporated.
Freezer coils are defrosted electrically.
NOTE: A freezer’s evaporator fans do not run
immediately upon start-up or during and immediately
following the defrost cycles. The fans start when the coil
reaches a cold temperature. This prevents the fans from
blowing heated air on the stored products.
DEFROST TIMERS
Undercounter freezer models F-10E, FS-10E, and
FSC-10E use an adjustable defrost timer which may be
custom-set to initiate defrost periods. All other models
use non-adjustable freezer defrost timers, which
automatically initiate at pre-set intervals and for a
pre-determined duration.
DEFROST SETTINGS
The defrost timer is factory preset to defrost the
evaporator coil each day at 2:00 AM, 8:00 AM,
2:00 PM, and 8:00 PM.
If you wish to change the defrost times, remove the pins
from the outer dial and re-insert them into the desired
time slots. (Refer to drawing.)
Defrost Timer
SETTING DEFROST TIME
The defrost timer must be set to real time after the power
is turned on, or after a power failure.
To set the time:
1. Grasp the knob in the center of the inner dial.
2. Turn it counterclockwise to rotate the outer dial.
3. Line up the current time of day on the outer dial with
the pointer.
! Caution
Leave at least one hole between adjacent pins.
Important
Set the defrost timer to defrost the cabinet during
the lowest usage periods.
