ADJUSTMENTS
Condenser water valve pressostat
(UP TO WHP AGS 841 WATER COOLED)
This pressostat controls high pressure by opening and closing the condenser water valve. Differential is a
fixed 1 Kg/cm2 (14 Psi). The valve closes at 16 Kg/cm2 (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 clockwise. A full turn is equivalent to about 1.5 Kg/cm2.

Water Pressure Control Valve

FROM AGS 843 (ONLY ON WATER COOLED MACHINES)
•High pressure should be maintained at 16-17 bar (228-240 Psi) must be maintained which corresponds
to a water temperature of 40°C ( exit temperature).
•When temperature exceeds 32°C, pressure and temperature of water at exit increase.
REGULATION: Water pressure and temperature can be decreased by regulating screw clockwise.
