The timer will need to be reset after a fail-
ure of the power supply, or if the power is turned
off for an extended period of time.
The defrost cycle is time initiated-
temperature terminated. The defrost stat is lo-
cated on the left hand side of the evaporator, on a
return bend of the tubing near the rear of the
evaporator. When the stat sens es a temperature
of 58ºF / 14ºC the defrost cycle is terminated. If
the stat should fail, then defrost is terminated by
the failsafe setting on the timer.
TEMPERATURE CONTROL –
The temperature control is located in the
electrical enclosure. The control is factory pre-
set to maintain ice cream storage temperatures.
Turning the control clockwise will derive colder
temperatures . The sensing tube for the control is
mounted on the cabinet interior rear wall. Access
to the tube is gained by removing the interior
rear wall panel .
CONDENSER –
The fin and tube condenser requires peri-
odic cleaning. To clean the condenser, remove
the front access panel. Using a soft brush, re-
move the dirt and lint off the fins. A vacuum or
compressed air may also be used. NEVER USE
A HARD OBJECT TO CLEAN THE F INS AS
DAMAGE TO THE CONDENSER MAY OC-
CUR!!
A regular schedule should be established
for the cleaning of the condenser. Failure to keep
the condenser clean will result in premature com-
pressor failure and/ or efficiency loss. Location of
the cabinet in the store and store traffic should be
considered when setting up this s chedule.
TEMPERATURE CONTROL
REPLACEMENT -
If there is product in the cabinet, it
must be placed in a storage freezer. Discon-
nect power to the cabinet. Remove the front
and left side access panels. Remove electri-
cal enclosure cover. Remove the knob on the
control and the two screws holding the plate
and control body in place. Remove the flag
connections from the control. Remove the
interior bottom pans and the rear interior
wall.
The wall has two screws, one in each
upper corner, holding it in pl ace. The sens -
ing bulb for the control is clamped to the
rear wall. Remove the clamp and replace the
control. Assemble in reverse order, reset
timer, and reconnect the power supply. Al-
low the cabinet to pull down to proper tem-
perature before reloading.
DEFROST STA T REPLACEMENT -
Remove product from cabinet and place in
another freezer. Disconnect power to the
cabinet. Remove front and left side access
panels. Remove electrical enclosure cover.
Remove proper wires from stat connected to
terminal board. Remove interior bottom
pans. Remove stat from return bend on
evaporator coil and install new stat making
s ure retaining clip holds stat to tubing
tightly. Cut wires from old stat and tape
wires to new stat wires. Gently pull old
wires guiding wires through hole penetra-
tion in bottom of case. Connect new wires to
corres ponding numbers on terminal board.
Reset timer and reconnect power to cabinet.
Allow cabinet to pull down to proper tem-
perature before loading.
