5 - Do not obstruct air intake and discharge openings: 15 cm
(6") minimum air space all around the dispenser.
6 - Do not put objects or fingers in panels louvers and faucet
outlet.
7 - Do not remove bowls, augers and panels for cleaning or
routine maintenance unless the dispenser is disconnected
from its power source.
5 OPERATING PROCEDURES
1 - Clean and sanitize the unit according to the instructions in
t h i s m a n u a l . S e e c h a p t e r 5 . 3 C L E A N I N G A N D
SANITIZING PROCEDURES.
2 - Fill the bowls with product to the maximum level mark. Do
not overfill.
The exact quantity of product (expressed as liters and
gallons) is shown by marks on the bowl.
3 - In case of products to be diluted with water, pour water into
bowl first, then add correct quantity of product. In case of
natural squashes, it is advisable to strain them, in order to
prevent pulps from obstructing the faucet outlet.
4 - To obtain the best performance and result, use bases
designed to be run in Granita freezers. Such bases have a
sugar content of 34 degrees Baumé corresponding to 64
degrees Brix (equivalent to a specific gravity of about 1.3
kg/liter).
For Granita the bases are to be diluted with water on a 1
plus 4/4.5 basis.
For soft drinks the bases are to be diluted with more water,
on a 1 plus 5/5.5 basis.
In any case follow the syrup manufacturer's instructions for
both Granita and soft drink recipes.
If natural juices (e.g. lemon, orange) as well as sugarless
products (e.g. coffee) are used, dissolve 5.3 - 7 oz. of
sugar per 0.25 gallons.
IMPORTANT
However Granita mix may be done, its Brix (sugar
percent content) must be at least 13.
5 - Install the covers and check that they are correctly placed
over the bowls. The dispenser must always run with the
covers installed to prevent a possible contamination of the
product.
6 - Set
the
control
switches
5.1 DESCRIPTION OF CONTROLS.
7 - Always leave the dispenser on, as the refrigeration stops
automatically when Granita reaches the proper thickness.
The mixers will continue to turn.
5. 1 DESCRIPTION OF CONTROLS
The dispenser is equipped with a power switch and a light
switch. In addition each bowl is individually operated by a
mixer/refrigeration switch. In fact it is possible to dispense both
soft drinks and Granita.
When a bowl is in Soft Drink mode the beverage temperature
is controlled by the corresponding thermostat.
When a bowl is in Granita mode the mix viscosity is controlled
by the corresponding adjustment screw located in the rear wall
of each container (for temperature and viscosity setting make
reference to chapter 5.2 OPERATION HELPFUL HINTS).
All the switches are located on the faucet side of the dispenser
as
shown
in
chapter
in switch panels protected by switch covers (see figure 2).
In addition all the models are equipped with an automatic
safety pressure switch to prevent damages to the compressor.
The lighting of the warning light at the left of the switch covers
means insufficient ventilation of the unit. In this case check that
all around the dispenser there is sufficient space for ventilation,
at least 15 cm (6") on each side and that condenser filter is free
from dust or other obstructions.
In case the warning light is still ON even after these operations
have been carried out, Service call is required.
With reference to figure 3 dispenser controls functions are as
follows:
Power switch (A)
0 position
:
power is turned OFF to all functions.
I position
:
power is turned ON to all functions
and the other switches are enabled.
The fan motor runs.
Light switch (E)
0 position
:
all top cover lights are OFF.
I position
:
all top cover lights are ON, provided
that power switch (A) is set to I.
Mixer/refrigeration switch (B)
I position
:
mixer and refrigeration ON.
SOFT DRINK mode.
0 position
:
OFF.
