Maintenance; Troubleshooting - Vinservice LIFE 50 Operation And Maintenance Book

MAINTENANCE

The appliance must not be cleaned by water jetting
Ordinary Maintenance
Ordinary maintenance can be carried out by unqualified staff provided that
the rules reported below are complied with.
• Every day check for any possible leakage.
• Every six months clean the condenser (L) blades by means of brushes and/or com-
pressed air jets. Be careful not to bend the blades. They are sharp, therefore always
wear leather gloves.
• Every month, or as needed, sanitize or wash the cooling coils (A) through which the
beverages flow. Wash and rinse them with plenty of water. Use special food-specific
detergents, according to the manufacturer's instructions.
• Every month check that the overflow tube (Q) is not clogged by ice or dirty or cra-
shed.
• Every month clean the vacuum device from any dust, filaments, paper which may
overheat the motors or cause malfunctions.
EXTRAORDINARY MAINTENANCE
Extraordinary maintenance must be performed by specialized personnel exclusively.
• Clean the tank (E) every year.
To this end, drain the tank after the ice bank has totally thawed. DO NOT use sharp
objects which may pierce the tubes or the tank. Never use abrasive products. Correct
cleaning improves the chilling performance. After cleaning, fill the tank as previously de-
scribed with clean water, without any additives, up to 2 cm from the overflow tube.
• If the power cable is damaged, have it replaced by the manufacturer, its customer
service or qualified staff in order to avoid any risks.
STORAGE DISASSEMBLY AND DISPOSAL
• If the machine remains unused for long periods, disconnect the power cable, the
electric system and the hydraulic system; drain the machine and clean it, disinfect
and wash the cooling coils. Let the cleaned parts dry out and set them in place; at
this point, store the machine in its original packaging, if available. Never leave the
machine without its original packaging.
• VINSERVICE will not be held responsible for the disposal of packaging materials or
machine parts or products used for its operation, such as refrigerant gas, compressor
or pressurized container, condensers, etc. Therefore the Customer will be held direct-
ly responsible for the disposal of such substances, that are potentially harmful for the
environment.
The appliance must not be cleaned by water jetting
Ordinary Maintenance
Ordinary maintenance can be carried out by unqualified staff provided that
the rules reported below are complied with.
CHANGE OF TANK WATER
When the tank water needs to be changed or disposed of, following this procedure:
1. Disconnect the machine form the power line.
2. Remove the upper cover
3. Wait for the ice bank to be thawed completely
4. Drain the tank through the drain pipe along the machine side
5. Fill the tank up to 2 cm from the overflow pipe
6. After repositioning and reconnecting the cooling unit repeat passages 2 and 1 in the
contrary order.
N.B. All control and maintenance operations must be
carried out after stopping the machine and discon-
necting the power cable, that is with the plug out of
the socket. All operations, excluding those reported
below, must be carried out by specialized and autho-
rized staff.

TROUBLESHOOTING

ANOMALY DETECTED
• The chiller does not work
and the main switch (IG)
warning light does not turn
up
• The machine does not
cool (the fan (M), the stirrer
(F) and the compressor (H)
do not work)
• The refrigerating unit is
working, but the stirrer (F)
is not working
• The machine does not
cool (the fan (M), and the
compressor (H)
working but the stirrer (F) is
working)
• The machine does not
cool (the compressor (H) is
not working but the fan (M)
and the stirrer (F) are wor-
king)
• The compressor is wor-
king continuously and does
not stop, causing the beve-
rages to freeze
• The machine does not
cool (the fan (M) is not wor-
king, but the compressor
(H) and the stirrer (F) are
working
• The stirrer (F) motor is
noisy
• The chiller works correct-
ly, but no beverages are di-
spensed
