Safeguard Feature

In addition to standard safety controls, your Manitowoc ice machine features built-in SafeGuards. The ice machine will stop when conditions arise that would cause major component failure.

RESET PROCEDURE

SAFEGUARD INDICATOR LIGHTS

1.Move the ICE/OFF/CLEAN toggle switch to OFF and then back to ICE.

A.If a safeguard feature has stopped the ice machine, it will restart after a short delay. Proceed to step 2.

B.If the ice machine does not restart, see “Ice Machine Does Not Operate” on previous page.

2.Allow the ice machine to run to determine if the condition is reoccurring.

A.If the ice machine continues to run, the condition has corrected itself. Allow the ice machine to continue running.

B.If the ice machine stops again, the condition has reoccurred.

SafeGuards

No Water

Gear Motor Speed is Incorrect

QF400/QC700/QF800 Only - Discharge line temp. is too high or low during the freeze cycle.

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. During the Standby Mode the corresponding light flashes continuously (disch temp, water level or speed). If the same failure keeps occurring, the ice machine will initiate a SafeGuard Mode and remain off until manually restarted.

During a SafeGuard Mode the corresponding light (disch temp, water level or speed) 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.
