Beverage temperature adjustment:
proper beverage
temperature is factory preset. To reset, turn the knob loca-
ted in each switch box as follows:
- toward right (clockwise) to decrease temperature.
-toward left (counterclockwise) to increase temperature.
Note: beverage temperature is controlled by the ther-
mostat only when the mixer/refrigeration switch(es)
are in I position, Soft Drink mode.
3 - The length of time for freeze down of Granita is governed
by many variables, such as ambient temperature, mix ini-
tial temperature, sugar content (Brix level) and viscosity
setting.
4 - To shorten Granita recovery time and increase producti-
vity, it is advisable to pre-chill the product to be used in the
dispenser.
5 - To shorten Granita recovery time and increase producti-
vity, the bowl should be refilled after the product level
drops lower than half of the evaporator cylinder and at the
start of each day.
6 - For good product conservation the dispenser must run
overnight, at least in Soft Drink mode.
If this is not possible and product is left in the bowls overni-
ght, the mixer/refrigeration switches must be set to the I
position at least one hour before the unit is switched off.
This eliminates any block of iced product forming overni-
ght, which could result in damage to mixers or to their
motor when the unit is switched back on. In any case,
before the unit is restarted, make sure that no blocks of ice
have been formed; if so, they are to be removed before the
unit is switched on. Overnight operation in drink mode also
eliminates possible ice accumulation from condensation all
around the bowls.
7 - Mixers must not be turned off when frozen product is in the
bowl: if not agitated, the product may freeze to a solid
block of ice. If the mixers are turned back on in this situa-
tion, damage to the mixers and their motor may result.
Therefore, mixers may be restarted only after product is
melted.
8 - The dispenser is equipped with a magnetic coupling by
which the gear motor (located outside the bowl) drives the
mixers (inside the bowl).
The magnetic drive operates as an “intelligent clutch” able
to automatically disconnect the mixers in case they are
seized by ice or other causes.
This inconvenience can be soon noticed since an intermit-
tent dull noise warns that mixers are still.
In this case it is necessary to unplug immediately the
dispenser, empty the bowl and eliminate the cause of sei-
zing.
9 - The dispenser must be able to emit heat.
In case it seems excessive, check that no heating source
is close to the unit and air flow through the slotted panels is
not obstructed by wall or boxes. Allow at least 15 cm (6”) of
free clearance all around the dispenser.
In any case if the product in the bowls is frozen and the
pressure switch warning light is OFF the unit is running
properly.
10 -Restrictor cap: when the unit is used in Soft Drink mode it
is advisable to install the restrictor cap on the faucet outlet
in order to reduce the drink outflow (see figure 4).

5. 3 CLEANING AND SANITIZING
PROCEDURES
1
- Cleaning and sanitizing of the dispenser are
recommended to guarantee the conservation of the best
product taste and the highest unit efficiency. This section
is a procedural guideline only and is subject to the
requirements of the local Health Authorities.
2 - Prior to the disassembly and cleaning, the machine must
be emptied of product. To do this proceed as follows:
- set the power switch to I position
- set mixer/refrigeration switch(es) to I position (Soft Drink
mode)
- place a pail under each faucet and drain all product from
bowls
- set all control switches to the 0 position
5. 3. 1 DISASSEMBLY
1 - Remove cover from the bowl.
2 - Remove the bowl by lifting its faucet side up and off the
fastening hooks (see figure 5) and slide it out (see figure
6).

ATTENTION
Before any disassembly and/or cleaning procedure
make sure that the dispenser is disconnected from its
power source by unplugging it or switching off the 2-
pole wall breaker.
