A. STIRRING ONLY-OFF-STIRRING & FREEZING
SWITCH
The STIRRING ONLY-OFF-STIRRING & FREEZ-
ING switch is a three-position toggle switch used to
control the operation of the refrigeration system and
agitator. When the switch is placed in the STIR-
RING ONLY position, the refrigeration system will
be off and the agitator will rotate for cleaning, or if
stirring is required when the store is closed. When the
switch is placed in the OFF position, the refrigeration
system and agitator will be off. The switch should be
placed in the STIRRING & FREEZING position for
normal operation.
B. RESET SWITCH
The reset switch is a two-position breaker switch. This
switch is used to protect the freezer from mechanical
damage. The switch must be in the NORMAL
OPERATING POSITION (up) before the freezer will
operate.
Any time a condition occurs which causes the
agitator drive motor to draw excessive current, the
reset switch will automatically switch to the
OVERLOAD CUT-OUT FREEZER NOT OPERAT-
ING position. This will shut down the freezing and
agitation action of the freezer to protect the agitator
drive motor from burning out.
Should the reset switch ever trip out, move
the STIRRING ONLY-OFF-STIRRING & FREEZ-
ING toggle switch to the STIRRING ONLY position.
Then move the reset switch back to NORMAL
OPERATING POSITION (up) and allow the freezer
to stir, without refrigeration, for five minutes. After
five minutes of stirring, return the STIRRING
ONLY-OFF-STIRRING & FREEZING switch to the
STIRRING & FREEZING position.
C. 24 HOUR TIMER
To program the timer, rotate program disc in the
direction of the arrows to align the correct day/time
with the time of day mark. Then pull out for Off time
or push in for On time. Each actuator is equivalent
to 15 minutes time. Check for AM/PM centered
between 12 and 12 on rotating disc. At a 6:00 setting the
indicator will point to AM or PM.
D. HIGH PRESSURE MANUAL RESET SWITCH
The HIGH PRESSURE MANUAL RESET SWITCH is a
safety switch designed to protect the compressor from
damage due to excessive head pressure. When tripped,
the lever will be out; push to reset.
E. SPIGOT ASSEMBLY
Dispensing of frozen mix is done by the SPIGOT
ASSEMBLY. By pulling the spigot plunger out, mix
in the form of ice crystals is dispensed through the
port on the bottom of the SPIGOT ASSEMBLY. To
stop dispensing, push the spigot plunger in.
F. FLAVOR BOTTLES
The FLAVOR BOTTLES are operated by a spring
loaded, push-button pump. By pushing down, 1/4
ounce (7.39 ml) of flavor is dispensed.
3.3 DRAINING THE FREEZER FOR DISASSEMBLING
AND CLEANING
After installation and initial set-up, the freezer exterior
must be cleaned and the freezer parts must be disas-
sembled, cleaned and sanitized. Cleaning and sanitizing
MUST be done before the initial freeze down and operation.
Subsequent cleaning and sanitizing, after the freezer has
been operated and product has been dispensed, will
require the freezer to be completely drained of all unused
mix. Perform the following steps to drain the freezer of any
unused mix:
A. Set the STIRRING ONLY-OFF-STIRRING &
FREEZING switch to the STIRRING ONLY position
well in advance of cleaning and sanitizing to assure
complete defrosting and draining of the product
cylinder.
B. While the freezer is in the STIRRING ONLY mode,
remove the unused flavoring from the flavor bottles.
All unused flavoring should be poured into the
containers from which they came.
C. Remove the Sani-tray and cover by gently pushing
up to disengage from the support pins and pulling
out and down (Fig. 13).
D. With a bucket placed below the drain spigot, pull the
spigot to dispense (Fig. 14).
E. When liquid product is completely drained, empty
the bucket into the sink. Any remaining ice can be
removed by circulating warm water through barrel.
