Always start with a cleaned and sanitized dispenser as per previous instructions. Following these instructions is critical to
the maximum operating efficiency of the machine.
1. Remove the restrictor tube from the bottom of the
mix pan and set aside in a sanitary location.
2. Place a 16 oz. Cup under the spigot and open the
spigot handle. Pour
approximately one quart
of fresh product mix into
the mix pan. (This will
chase the sanitizing
solution from the mix pan
and freezing cylinder.)
Close the spigot handle
when the sanitizer is
purged from the system.
3. Fill the freezing
cylinder until the mix
comes out of the
recirculation hole on
units with two mix inlet
holes or until the freezing
cylinder stops bubbling on units with only one mix inlet
hole.
4. Install the removable restrictor tube with a gentle
twisting motion into the front hole if the mix pan has two
mix inlet holes. For units with only one hole, simply
insert the restrictor tube in the only mix inlet hole.
5. Fill the mix pan with chilled, properly mixed product.
Keep the mix level in the mix pan at least one inch
(25 mm) deep at all times to avoid starving the freezing
cylinder. A MIXOUT light (Fig. 38) located on the front
of the machine (one per freezing cylinder) is activated
when the mix solution drops to a potentially damaging
level.
6. Set the control switch to the “AUTO” position to
start the machine.
7. Allow the compressor to cycle 3 or 4 times
dispensing a sample of the product after each cycle to
check for consistency. If the machine is not dispensing
the product at the desired consistency after four full
cycles, refer to the Consistency Control Section of this
manual. Initial pull-down time may vary due to model,
product and ambient conditions.
8. Replace the mix pan lid and always operate the
machine with the lid on the mix pan reservoir.
Note: SaniServ dispensers are designed to run frozen
beverage products having a Brix (sugar content) range
of 12.5 to 14 with a dispense temperature of 26°F to 28
°F (-3.3°C to -2.2°C).
Brix reading is taken by placing a small sample of
normally diluted concentrate on the viewer of a
refractometer. If a refractometer is not available,
contact the mix supplier.
Do not use a mix with a Brix reading of less than
12.5. Doing so may result in serious damage to the
machine.
If the Brix reading is above 14.0 or the alcohol content
is too high, the freezing point of the solution may be too
low to form slush.

OPERATION
Fig. 37
Dispensing Product
Operation (Filling and Starting)
If the liquid level sensor detects a low level condition, it
will flash the “MIXOUT” light and activate the beeper
for three minutes or until the mix pan is filled to satisfy
the mix level probe. If the beeper is activated for more
than three minutes, the light will begin to glow
continuously, the beeping tone will slow down, and the
machine will no longer dispense product.
Control Switch Positions
“CLEANOUT” Position: The dasher motor operates
continuously and the compressor will not come on.
The mix out level sensor will turn on the “MIXOUT”
light but will not activate the beeper.
“AUTO” Position: The dasher motor operates
continuously. Upon machine start up the compressor
will run until proper product consistency is reached.
Then the compressor will shut off.

Closed Hours/Shut-Down: If the machine is turned
off during closed hours, to resume operation:
1. Set the control switch to the "CLEANOUT" position.
2. Dispense two quarts (2 liters) of product into a
sanitized pitcher and pour it back into the mix pan.
Doing so serves as a mixing process to eliminate any
overnight separation.
NOTE: NEVER POUR FROZEN PRODUCT INTO
THE MIX PAN. LET IT MELT FIRST.
3. Set the control switch to the "AUTO" position and
resume operation.
Mixing: Make certain that the product is prepared per
label instructions. The machine is designed to operate
with frozen product base having a brix range of 12.5 to
14.0. To ensure consistency and quality, use a mixing
container large enough to hold 5 gallons (20 liters) with
1 gallon (4 liter) markings to allow accurate mixing of
the frozen beverage base. Stir well before adding to
the mix solution to the mix pan. Refrigerate the base
after diluting. Keep the empty gallon bottles with their
lids or caps installed and refill them with diluted base
for easy access during busy operating periods.
Filling: Always fill the machine at the start of each
day. Fresh prechilled mix will produce the best results.
Mix Pan Lid: Be sure to leave the lid in place on top of
the machine to prevent any foreign materials from
contaminating the mix.
Drip Tray: This should be removed daily and cleaned
to remove residue (Fig. 37).
Front Plate: This component (Fig. 33) is the plastic
device from which the product is dispensed. It is
designed and made for strength and durability.
However, through improper use, it can be damaged.
Use the following information for proper care.
1. Do not lubricate the large o-ring on the rear of the
front plate. If lubricated, it will not seal properly and
product will leak from the front plate (Fig. 33).
2. Do not over tighten the knobs.
3. Always tighten the front plate knobs evenly. Do
not attempt to turn one knob all the way down and then
the other(s). Doing so will bind the front plate and
result in breakage.
4. Improper installation of the stator rod can cause
breakage. The stator rod must be properly seated in
the dasher before installing the front plate. If the stator
rod is improperly installed, subsequent tightening of the
knobs will break the front plate.
5. Do not attempt to wash the front plate or any other
machine components in a dishwasher.
Mix Out Light: When the mix out light comes on, fill
the mix pan. The mix pan must be filled immediately to
prevent air from entering the freezing cylinder. If air
enters the freezing cylinder, it will create the condition
known as “starving the machine”, causing freeze-up
and vibration. If this condition occurs, set the control
switch to the "OFF" position and add mix to the
mix pan. Allow the freezing cylinder to refill and return
the control switch to the "AUTO" position.
