Components Energized when the Control Switch is in the "DRAIN" Position
The "DRAIN" position on the control switch is used when cleaning and sanitizing the unit. This allows cleaner and sanitizer to drain from the reservoir and evaporator assembly. When switching to the "DRAIN" position during the freeze cycle, the drain valve does not energize until the 150 second shutdown sequence terminates (2. Shutdown & Restart).
Note: To bypass the 150 second shutdown sequence, move the power switch to the "OFF" position, place the control switch in the "DRAIN" position, then move the power switch back to the "ON" position.
FT - fill timer (low water safety) GM - gear motor
GMPR - gear motor protect relay LF/S - lower float switch UF/S - upper float switch WCR - water control relay
WV - inlet water valve
