Condenser water valve pressostat
This pressostat controls high pressure by opening and closing the condenser water valve.
Differential is a fixed 1 Kg/cm

(14 psi.). The valve closes at 16 Bar (228 psi.) which is
equivalent to a water exit temperature of 38ºC. Below this pressure it will be difficult to unstick
the cubes in the defrosting stage. Above this pressure, compressor life and ice production are
both reduced. Pressure can be increased by turning the small screw on the pressostat
clockwise. A full turn is equivalent to about 1.5 Bar.
Pressure Control
Fan pressostat (air condensation)
Pressure Control operates on high pressure by starting and stopping fan. Differential is a fixed
(1Bar or 14 psi.) Cut-off pressure must be 16 Bar (228 psi.) Low pressure values may cause
