Safety pressostat

Start up timer

This timer delays start up for 2-

3 minutes after machine is switched on. This delay allows ice

formed on evaporator to partially melt. When the machine restarts ice will be wet and loose in

evaporator, and hence gearbox/auger breakage risk is reduced.

THIS TIMER ONLY WORKS WHEN MACHINE IS WARM.

Safety devices.

•

Overload protection device: will trip if maximum current intensity (A) is exceeded, hence

preventing the motor from overheating due to current peaks. When overload trip

s, a red light

will switch on in the front panel. The overload must be reset manually, to do so the front grille

and overload cover must be removed.

• Thermal protection device: will trip if temperature in motor exceeds set point. When this

device trips, the same red light will switch on in the front panel. In this case, however, reset is

automatic.

• Low water level sensor: a magnetically activated sensor (buoy) located inside the water

trough will switch off the machine should the level of water fall below the set minimum. A red

light will switch on in the front panel labelled “low water level”. Reset is automatic.

• Bin full of ice: a micro-switch located at the top of the evaporator will stop the machine when

the bin (and the ice discharge tube leading to th

e bin) is full of ice. An orange light will switch

on in the front panel labelled “bin full”. Reset is automatic.

This safety device trips when pressure is too

high. Pressure might reach

the set limit of 27 Kg/cm2 when:

Air circulation is not sufficient, room temperature is too high, condenser

is dirty or fan motor is broken. (air-cooled models)

) Insufficient water in the cooling circuit, inlet water temperature is too high

or fan motor is broken (water -cooled models).

The safety pressostat will switch off the machine completely until pressure

drops again to its lower set point value (21 Kg/cm2)

HIGH PRESSURE SET POINTS (non-adjustable):

27-21 Kg/cm2 (380-296 Psi.)
