AN rein NT 1 tu33V14 3L0ONW3H ICE O MATIC REMOTE CONDENSER SYSTEMS INTRODUCTION Ice O Matic Remote Condenser Systems are made up of three packages The remote condenser the ice making unit and the pre charged line set Pre charged line sets are available in either 25 or 40 foot lengths Normal installation of the ice making unit should be followed Please see installation instructions included with the ice maker In any installation the pre charged line sets consisting of a liquid line dia and a discharge line V2 dia are used as a one time initial charge type of installation This is once the sealed couplings are con nected and the internal seal is broken the lines cannot be disconnected without losing the refrigerant charge They are however reusable and when they are removed and re connected the complete refriger ation sytem must be evacuated and re charged with the proper amount of refrigerant See page 3 for proper refrigerant charges GENERAL DESCRIPTION The remote condenser should be used in areas where sufficient airflow is not available in the area the ice maker is being installed or the heat being rejected by the condenser coil is undesirable The condenser coil should not be exposed to temperatures below 20 F or above 120 F The remote condenser functions as a normal refrigeration system until the temperature at the condenser coil drops below 70 fahrenheit At this time th
