(exit temperature).
• If mains water temperature exceeds 32°C, the above values of high pressure and water
temperature at exit will be higher.
ADJUSTMENT: High pressure (and water temperature) can be decreased by opening valve
(turn screw clockwise).
Fan pressostat (air
–cooled models)
High pressure is controlled by starting and stopping fan, which provides airflow through
condenser. Differential is fixed. (1Kg/cm2 or 14 Psi.) Cut-off pressure should be 16 Kg/cm2 (228
Psi.) Low pressure values in circuit may cause gearbox malfunction due to excessive ice
production. Pressure values higher than 14 Kg/cm2 will diminish ice production and may
shorten compressor life. Pressure can be regulated by rotating screw on Pressure Control Valve
(clockwise to increase pressure). One full turn is equivalent to about 1.5 Kg/cm2.
