3. WATER DRAIN WATER COOLED MODELS The water drain line from the condenser on water cooled versions is internally connected with the drain fitting of the unit It is strongly recommended therefore to install a vertical open vent to the high point of the drain line high enough to ensure good drainage and to direct the drain line to a trapped and vented floor drain receptacle This ensures proper flow of the drained water as in the case of poor drainage the water running out of the condenser may leak through the unit drain tubing into the ice storage bin or into the sump reservoir NOTE The water supply and the water drain must be installed to conform to the local codes In some cases a licensed plumber and or a plumbing permit is required mk D Final Checklist Is the machine in a room where the ambient temperatures are within a minimum of 10 C 50 F even in winter months Is there at least a 15cm 6in clearance around the unit for proper air circulation Is the machine level IMPORTANT Have all the electrical and plumbing connections been made and is the water supply shut off valve open Has the voltage been tested and checked against the rating on the data plate Has the water supply pressure been checked to ensure a water pressure of at least 1 bar 14psi Check all refrigerant lines and conduit lines to guard against vibration and possible failure Has the bin liner and cabinet been wiped clean Has the owner user been
