11. ser walls with chemicals It is recommended that the scale removal should be performed by your WHIRLPOOL ice maker dealer Air Cooled Models Adequate air must be allowed to flow through the finned coils of the remote condenser A dirty or clogged condenser prevents proper air flow resulting in reduced capacity of the ice machine and subjects the components of the unit to higher than normal operating temperatures The condenser coil should be inspected approximately once a month and cleaned when necessary Use a vacuum cleaner and stiff brush to remove the accumulation of lint and dirt CLEANING amp SANITIZING THE ICE MAKING SYSTEM Impurities are rejected from the circulating water that freezes into ice These impurities collect on the freezing mechanism and in the water system and form a hard scaly deposit Generally this scale prevents a rapid release of the ice slab during the harvest cycle and may cause the warning light to start blinking and glow brighter The water and ice making system therefore should be periodically cleaned and sanitized The frequency of cleaning will depend on local water conditions and how rapidly scale accumulates Cleaning and sanitizing is not too difficult Having a qualified service representative clean the system the first time should make subsequent cleaning easier to perform if the operator wishes to take over this portion of the ice machine maintenance Follow this procedure to assure that the
