Safety pressostat
This safety device trips when pressure is too high. Pressure might reach
the set limit of 27 Kg/cm2 when:
a) Air circulation is not sufficient, room temperature is too high, condens
is dirty or fan motor is broken. (air-cooled models)
b) Insufficient water in the cooling circuit, inlet water temperature is too h
or fan motor is broken (water -cooled models).
The safety pressostat will switch off the machine completely until pressur
drops again to its lower set point value (21 Kg/cm2)
HIGH PRESSURE SET POINTS (non-adjustable):
27-21 Kg/cm2 (380-296 Psi.)
6.5.
Start up Timer
This timer delays start up for 10 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.
