2 - Pour the solution into the bowl(s).
3 - Using a brush suitable for the purpose, wipe the solution
on all surfaces protruding above the solution-level and on
the underside of the top cover(s).
4 - Install the top cover(s) and operate the unit. Allow the solu-
tion to agitate for about two minutes. Drain the solution out
of the bowl(s).
5 - Use fresh product to chase any remaining sanitizer from
the bowl(s). Drain this solution. Do not rinse out the
machine.
6 ROUTINE MAINTENANCE
1 -
Daily:
inspect the machine for signs of product leaks past
seals and gaskets. If proper assembly does not stop leaks
around seals or gaskets, check for improper lubrication,
worn or damaged parts. Replace parts as needed.
2 -
Monthly:
remove the dust from the condenser filter. To do
this unplug the unit or switch off the 2-pole wall breaker
and then remove the only left panel (from faucet side)
unscrewing the two plastic coated screws.A blocked filter
will reduce performance and could cause compressor fai-
lure.
6. 1 MAINTENANCE (TO BE CARRIED OUT
BY QUALIFIED SERVICE PERSONNEL
ONLY)
1 -
Annually:
remove the panels and clean the inside of the
machine including the base, side panels, condenser, etc.
2 - When installed, the anti-splash filters inside the slotted
panels must not be removed.
3 - Never remove the insulating jacket from around the suc-
tion tubing of the evaporator (the copper tubing located on
the right side of gear motor). In case the insulating jacket is
missing replace the entire parts with original spare parts
from the supplier.
4 - In order to prevent any damages to the dispenser, all pla-
stics parts must be lubricated only with grease supplied by
the manufacturer or with another lubricating product suita-
ble for polycarbonate.
The electric diagram of the dispenser is located in the inner part
of the dispensing side panel.
7 DEFROST TIMER
The Defrost Timer, located on the right side of the unit,
automatically switches the dispenser from Granita mode to
Soft Drink mode and the opposite. This means that during
defrost periods frozen Granita will melt to thermostat setting
temperature and once defrost period has expired, the product
automatically freezes down again to Granita setting viscosity.
figure 16
To operate the defrost timer proceed as follows (see figure 16).
Set the time of the day by rotating the dial clockwise (arrow A).
Never rotate the timer counterclockwise
as this would
damage the internal machanism. Align the current time of day
with the arrow B on the timer face. This is a 24 hour timer
showing both A.M. and P.M.
1 - Program the defrost timer by pushing out on those tabs D
that correspond to the hours desired to defrost. Each tab
represents 15 minutes. A minimum of four to eight hours
are required to defrost frozen beverage (depending on
ambient conditions).
2 - The defrost timer has a three position switch located on
the dial:
Note:
when all the tabs are pushed in the defrost function is
OFF (the machine operates as if it were not equipped with
Defrost Timer).
8 AUTOFILL 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
ATTENTION
Condenser fins are very sharp. Use extreme caution
when cleaning.
