Water System - Follett Symphony E12CI425A Operation And Service Manual

Water system

The water level in the evaporator is controlled by a fill solenoid (Fig. 14) and level detecting sensors . Water sensing
rods (Fig. 15) extend down into the reservoir at the end of the evaporator assembly . The system works via electrical
conductivity as follows:
One of the longest probes is a common . When water is between any of the other probes and the common, the
PC board will sense the activation . During normal operation, the water level rises and falls between the Normal
High and Normal Low sensors . As water is consumed to make ice, the level will fall until the Normal Low sensor is
exposed, triggering the water feed solenoid on . Water will fill until the Normal High sensor is activated .
Note: The potable water dissolved solids content must be greater than 10 ppm for the water control system to
function properly . If using reverse osmosis water filtration system, ensure T .D .S level is greater than 10 ppm .
