1 INTRODUCTION
This operator’s manual is a complement to the standard
Granita machine operator’s manual available in the unit
package.
Carefully read first the standard unit Operator’s Manual and
then all the following sections of this one thoroughly to
familiarize yourself with all aspects of the system.
The purpose of the Autofill Device is to increase the
productivity of a Granita Machine far beyond the containers
capacity, allowing the automatic refill as soon as the product in
the containers drops lower a preset level.
In order to operate a Granita Machine equipped with Autofill
Devices a remote fill system is required.
The remote fill system is composed of all those parts that are
installed outside the dispenser and is intended to supply the
dispenser with the adequate and correct beverage to be
frozen.
It is not the aim of this manual to instruct about how to set up
and operate a remote fill system. To get more information
about that please make reference to our “Autofill System for
Granita Machines - General description and typical installation
flow charts”.
2 INSTALLATION
1 - Loosen the fitting locker located on the rear cover of each
bowl equipped with Autofill Device and connect the remote
fill system using a 1/4” fitting suitable to the purpose.
Tighten the fitting locker.
2 - On the lower rear panel of the machine a 6-pole terminal
block is located. It is designed for connecting some
accessories such as a Safety Water Line Solenoid Valve
and one Sold-out Switch each bowl (see figure 1).
figure 1
3 - The Safety Water Line Solenoid Valve is intended to cut off
the main water line (if present in the remote fill system)
whenever the Autofill Device is not refilling.
The Sold-out Switch (one for each bowl) disables the
Autofill Device and activates acoustic and visual alarms
whenever the incoming beverage is sold out.
The Safety Water Line Solenoid Valve, if present, must be
connected to the unit using #1 and #2 poles of the
terminal block (see figure 1).
If a Safety Water Line Solenoid Valve is not used do not
use #1 and #2 poles.
If the remote fill system is equipped with Sold-out switches
connect their wires to #3 and #4 poles (for one bowl unit),
to #3, #4 and #5 poles (for two bowls unit) and to #3, #4,
#5 and #6 poles (for three bowls unit) as per figure 1
diagram.
4 - The Autofill Device doesn’t come presanitized from the
factory. Prior to starting operation an In-Place Sanitization
is t o b e pe r f or m e d ac c o r d in g w it h t hi s ha n d bo o k
instructions (paragraph 3.3 IN-PLACE SANITIZATION).
3 OPERATING PROCEDURES
Once the remote fill system is set up, follow the procedures
described in chapter 3.1 DESCRIPTION OF CONTROLS to
activate the Autofill system.
If the clip probe is properly installed and the bowl properly fitted
in their position, the remote fill system starts to operate and
feed the bowl through the hole in the rear wall. As soon as the
product level reaches the lowest tip of the probe, the priming
automatically stops.
As soon as the probe tip immersed in the product gets
uncovered (because of dispensed product), the solenoid valve
inside the rear wall automatically opens and fresh beverage
flows into the bowl until the probe tip gets covered again.
The solenoid valve opening occurs with about 10 seconds
delay to avoid that the irregular waving of product surface,
occasionally discovering probe tip, may be understood as level
dropping “cause of dispensing”.
A sold-out warning light along with a buzzer (visual and
acoustic sold-out alarms) are located respectively on and
inside the rear cover. They can run only if an applicable Sold-
out switch is connected to the terminal block (see figure 1).
3. 1 DESCRIPTION OF CONTROLS
Each Autofill Device is equipped with a three position switch
IMPORTANT
Whatever the remote fill system may be make sure that
the inlet product pressure into the Autofill Device is not
exceeding 2.5 bar (36 psi).
IMPORTANT
Safety Water Line Solenoid Valve must be 24V DC 12W
maximum.
IMPORTANT
If no Sold-out switch is used make sure that # 3, # 4, # 5
and # 6 poles on the terminal block are connected
together.
IMPORTANT
The device is designed so as no refilling occurs in case
either the clip probe is not properly installed or the bowl
not properly fitted.
