Cnm Series Ice Maker Frequently Asked Questions - Cornelius NORDIC ELITE Series Owner's Manual

CNM SERIES ICE MAKER FREQUENTLY ASKED
1. What is the factory float setting on a replacement float assembly?
Replacement float housings come with the high float set in the #1 position. The high float needs to be inserted, per
the provided instruction, into the correct float setting of the machine receiving the replacement float assembly.
2. What is the factory high float setting on a new machine?
The CNM series float settings by nominal capacity are listed below
Nominal Capacity
300lbs
400 through 600lbs
800 through 1100lbs
1400lbs
3. How do I adjust the ice bridge thickness?
The CNM series' bridge thickness may be adjusted by moving both a high and a low float.
• The low float is used for fine bridge thickness adjustment via an adjustment arm. Turning this arm counter-clockwise
lowers the float and increases bridge thickness. Rotating the arm clockwise raises the low float, decreasing bridge
thickness.
• A greater change to the bridge thickness than the low float adjustment can provide is possible by moving high float up
or down one position. Moving the high float up increases bridge thickness, while moving this float down, decreases the
bridge thickness.
4. Why is my new machine occasionally producing extra thick batches of ice?
When occasional thick batches of ice occur, the bridge thickness may be set too low. When a batch of ice does not
have a thick enough bridge, it can split and only have half a batch fall into the ice bin. The curtain is opened and
closed by this half batch, causing the machine to go back into freeze mode. The remaining ice from the previous cycle
is added to the new batch of ice being formed, causing it to be especially thick.
5. Why causes the machine to produce cloudy/hazy ice?
Cloudy ice is the result of impurities getting trapped as the ice forms. These impurities include dissolved mineral,
chemicals, and air. These are a few items to consider if your machine is producing cloudy ice:
• Verify the purge valve is operating correctly, and that the drain line inside the machine is not kinked or blocked in any
way.
• Use a vented drain line from the machine to the floor drain.
• Change the machine to use the "High Purge" setting in areas with water that has an elevated concentration of
dissolved minerals.
• Avoid using water that has had phosphate added or is from a water softener.
