ATER AND ILTRATION
Water quality and proper filtration are important for all ice makers. The correct filter is key to obtaining the
best performance from the equipment. Filters should be of the taste and odor variety only. Filters that
contain scale inhibitors or phosphates will cause chunklet ice to stick together or "bridge" in the bin. This
will result in agitator damage. As this type of ice maker uses 100% of the w2ater it takes in, those chemi-
cals will remain in the ice and cause pre-mature melting (bridging) in the storage bin.
Never use softened water. Softened water will cause the ice to stick together in the ice bin and will dam-
age agitator assemblies. Water temperature should be no cooler than 50
Warmer water may require pre-chilling for adequate production to be maintained. Water contains dis-
solved minerals. The measurement of these minerals is referred to as the waters TDS. Dissolved solids
cannot be removed by normal filtration. Removing these dissolved solids is comparable to trying to
remove the sugar from coffee once it has been poured in and stirred. A process called reverse Osmosis
is required to remove the dissolved minerals. In the absence of and R.O. System, a good maintenance
program can ensure proper performance and longevity from the ice maker.
The water float level should be even with the top refrigeration line in the evaporator.

ECHANICAL
The bin top models have a similar component layout, except for the remote units. The interiors of the ice
makers are divided in two halves. The back half contains the condensing unit.
The condensing coil is mounted horizontally above the compressor on the 500 and 700 models and ver-
tically behind the compressor on the 1000 series. Both are designed to flow air across the condenser
before compressor.
Water-cooled models cool the compressor with a tubular heat exchanger and a small fan that directs air
across the compressor.
