CME1356R and CME1656R
Adjustments
If there was a problem during Initial Start Up:
If a diagnostic light came on, check the following.
1. Water.
A water error could have been determined by the AutoIQ Controller if the inlet water valve does not fill the reservoir or if the water pump does not start and lower the water level in the reservoir. If either condition is found, the water error light will be switched on and the machine will Shut Down.
2. Refrigeration.
A refrigeration error could have been determined by the AutoIQ Controller if the water temperature did not drop during the freeze cycle. The Controller will next check the compressor discharge temperature. If the discharge temperature is too low, the refrigerant error light will be switched on, and the machine will Shut Down.
Note: The machine can be reset and restarted by pushing and releasing the Off push button switch, and then pushing and releasing the freeze push button switch.
Thermostatic Expansion Valve:
The TXV is not adjustable, do not attempt to adjust it.
How to Adjust the Amount of Water Purge
Adjustment is done by use of the control buttons on the AutoIQ Controller. Examine the next section to become familiar with the AutoIQ Controller before beginning.
1.If the machine is on, push and hold the OFF button for more than 3 seconds, then release it. This switches the machine Off.
2.Push and hold the OFF button for more than 3 seconds (just until all Lights flash on) then release it. Do not hold it in it too long.
3.Examine the green Lights. They should have all flashed once, then certain ones will have turned on to indicate which purge level the machine is set at. There are 5 levels of purge available:
1. Maximum Purge is when All 5 lights are ON. Use for extreme water conditions. Note: This setting may extend the Harvest cycle and reduce capacity.
2. Heavy Purge is when these 4 lights are ON: Freeze, Harvest, Clean, Off. Use for moderate to severe water conditions. This setting may extend the Harvest cycle and reduce capacity.
3. Standard Purge (factory setting) is when these 3 lights are ON: Harvest, Clean, Off. Use for typical water conditions.
4. Moderate Purge is when these 2 lights are ON: Clean, Off. This is for good water conditions.
5. Minimum Purge is when this light is ON: Off. For excellent water conditions.
Adjust by pushing and releasing the Freeze button. Pushing and releasing the Freeze button increases the purge one level up to the maximum, then it goes to the minimum.
4.The machine will automatically restart after 60
seconds of no switch inputs, or restart the machine by pushing in and holding the Off button for more than 3 seconds, then releasing it. The unit will then be Off. From there the machine may be placed in a freeze cycle by pushing and releasing the Freeze button.
