Ice Machine Operation

SAFETY LIMITS

Safety limits are stored and indicated by the control board. The number of cycles required
to stop the ice machine varies for each safety limit.
Safety limits can be reset with the On/Off toggle switch by starting a new ice making cycle.
A safety limit is indicated by a flashing Service Light on the control board.
• Safety Limit 1 - If the freeze time reaches 60 minutes, the control board automatically
initiates a harvest cycle. If three consecutive 60 minute freeze cycles occur, the SL#1
light on the control board will flash on/off at 1 second intervals. If 6 consecutive
60-minute freeze cycles occur, the ice machine stops and the SL#1 light on the control
board remains energized.
• Safety Limit 2 - If three consecutive 3.5 minute harvest cycles occur, the SL#2 light
on the control board will flash on/off at 1 second intervals. After 75 consecutive 3.5
minutes harvest cycles, the SL#2 light will be energized continuously. If 100 consecutive
3.5 minute harvest cycles occur, the ice machine stops and the SL#2 light on the control
board will be on continuously.
• Water Loss - If the water trough doesn't fill within 4 minutes of the water inlet valve
energizing, the ice machine will stop for 30 minutes then restart. If 100 consecutive
failures occur, the ice machine locks out and the SL#1 & SL#2 lights flash on/off at 1
second intervals.

OPERATIONAL CHECKS - PKM0335/PKM0425/PKM0535

All ice machines are factory-operated and adjusted before shipment. Normally, new
installations do not require any adjustment.
To ensure proper operation, always follow the Operational Checks:
• when starting the ice machine for the first time
• after a prolonged out-of-service period
• after descaling and sanitizing
NOTE: Routine adjustments and maintenance procedures are not covered by the warranty.
