MT GL/GLS
5 OPERATING PROCEDURES
ATTENTION
In case of damages, the power cord must be replaced by
qualified personnel only in order to prevent any shock
hazard.
1 Clean and sanitize the unit according to the instructions in
this manual. See chapter 5.3 CLEANING AND 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, potable 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.
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 150 - 200 grams of
sugar per liter.
IMPORTANT
Operate the dispenser with food products only.
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. There must be a correct electrical connection
between the bowl and the cover.
IMPORTANT
For LS models only: if the covers are not correctly instal-
led the unit does not run, the mixer does not rotate and
the refrigerator is switched off.
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
as shown in chapter
12
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
in switch panels protected by switch covers (see figure 1).
In addition all the models except MT 1 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.
II position : mixer and refrigeration ON.
GRANITA mode.
Thermostat (D)
Turn clockwise : to decrease temperature
