Granular Ice Technical Service Manual

Be sure voltage and frequency of mains supply is as indicated on rating plate.
1. Set appliance switch to ON position. All elements should be working except for fan (air-cooled
machines) which will commence operation only when high pressure activates it. All pilot lights
should be switched off except for power display (green), indicating that power is on. Otherwise
check the troubleshooting section of this manual.
2. Make sure fan blades don't come into contact with anything and that none of the tubes
vibrate.
5.3. Inspection and adjustment of water level in the tray
1. Make sure water level in trough does not go down completely as this will set off "WATER
LOW" sensor while machine is operating. Should this happen with a pressure higher than
1Kg/cm2 and filters in good condition, INCREASE LEVEL by bending the float arm upwards.
2. Turn machine off and wait for flotation valve to close before water escapes through maximum
level drain. If that happens and pressure is lower than 6kg./cm2, slowly bend and lower the
float’s arm until you have achieved an adequate flow.
IMPORTANT!
If water pressure exceeds 6 kg./cm2., a pressure reduction unit should be installed to maintain
pressure at 4kg./cm2.
5.4. Cross checking
a) Shut off water faucet. Water level will recede until automatic shut-off occurs.
b) Open water faucet. Water level will rise and machine operations will commence in 3 minutes’
time.
IMPORTANT!
Please instruct end user as to the correct maintenance procedures as described above.
The manufacturer declines all responsibility for damage caused by failure to properly
maintain the equipment.
