    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.
  • Page 18: Pressure Control

    Pressure Control Fan pressostat (air condensation) Pressure Control operates on high pressure by starting and/stopping fan. Differential is fixed. (1Kg/cm2 or 14 Psi.) Cut-off pressure must be 16 Kg/cm2 (228 Psi) Low pressure values may cause gearbox malfunction. Pressure values higher than 16 Kg/cm2 may shorten compressor life and diminish ice production.
