gearbox malfunction. Pressure values higher than 16 Kg/cm2 may shorten compressor life and
diminish ice production.
Pressure can be regulated by rotating screw on Pressure Control Valve (clockwise to increase
pressure). One full turn is aquivalent to about 1.5 Bar.
Safety pressostat
This safety device trips when pressure is too high. Pressure might reach
the limit when:
a)
Air circulation is not sufficient, room temperature is too high, condenser
is dirty or fan motor is broken. (air-cooled models)
b) Insufficient water in the cooling circuit, inlet water temperature is too high
or fan motor is broken (water -cooled models).
HIGH PRESSURE SET POINTS (non-adjustable):
27-21 Kg/cm2 (380-296 Psi.)
7. MAINTENANCE AND CLEANING INSTRUCTIONS
IMPORTANT!
**Maintenance and cleaning procedures as well as problems derived from failing to carry them
out are not covered by the warranty.
Proper maintenance is essential to obtain favourable ice quality and optimum functioning of unit.
Frequency depends on water quality and characteristics of room where unit is installed.
IMPORTANT:
** Maintenance/cleaning procedures should take place at least once every six months. If
concentration of air pollutants is high, complete procedures on a monthly basis.
