2 Beverage temperature adjustment: proper beverage
temperature is factory preset. To reset, turn the knob located in
each switch box as follows:
- towards right (clockwise) to decrease temperature.
- towards left (counterclockwise) to increase temperature.

thermostat 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 initial
temperature, sugar content (Brix level) and viscosity setting.
4 To shorten Granita recovery time and increase productivity,
it is advisable to pre-chill the product to be used in the
dispenser.
5 To shorten Granita recovery time and increase productivity,
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 overnight,
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 overnight, 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 situation, 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 intermittent
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 seizing.
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
figure 3
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
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.
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).
