SafeGuard Feature
The ice machine will stop when conditions arise that would
cause major component failure.
Standby Mode
The first time a failure occurs, the ice machine de-
energizes and initiates a Standby Mode. The ice machine
will remain off for 60 minutes, then automatically restart
to see if the problem reoccurs. If the same failure keeps
occurring, the ice machine will initiate a SafeGuard Mode
and remain off until manually restarted.
SafeGuard Indicator Lights
During a SafeGuard Mode, the corresponding control
board light will flash continuously.
The SafeGuard will remain in memory for 48 hours of
ice making time. After 48 hours of ice making time,
the SafeGuard will automatically be erased. If power is
interrupted during the 48 hours, the timing will resume
when power is applied to the ice machine.
Placing the toggle switch in the OFF position:
The corresponding light will flash continuously.
Placing the toggle switch in the ICE position:
The light will de-energize and a start-up sequence will
initiate. The corresponding light will flash anytime the
toggle switch is placed in the OFF position provided 48
hours of ice making time has not been exceeded.
