fittings and a shut off valve installed in an accessible position between the water supply line and the unit. Fig. 11 WATER SUPPLY - WATER COOLED MODELS. The water cooled versions require two separate inlet water supplies on models 40 and 60, one to supply water for the ice production and one for the water cooled condenser. Connect the male fitting of the condenser water inlet solenoid valve, using the second flexible tubing supplied, to the cold water supply line with regular plumbing fi
