Purge Adjustment - Scotsman CME686 User Manual

Purge Adjustment

Note: While the amount of water purge is
adjustable, only those installations with a water
supply known to be excellent (very low TDS)
should adjust to the minimum setting. See below
for purge adjustment instructions.
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.
·
2. Heavy Purge is when these 4 lights are ON:
Freeze, Harvest, Clean, Off. Use for severe
water conditions.
·
3. Standard Purge (factory setting) is when
these 3 lights are ON: Harvest, Clean, Off. Use
for moderate to severe water conditions.
·
4. Moderate Purge is when these 2 lights are
ON: Clean, Off. This is for typical 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.

Adjustments
Cube Size: Cube size is fixed and cannot be
adjusted.
Thermostatic Expansion Valve:
The TXVs are not adjustable, do not attempt to
adjust any of them.
If there was a problem during Initial Start Up:
If an error light came on, check the following.
1. Water error.
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.
2. Refrigeration error.
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: Reset and restart the machine by
pushing and releasing the Off push button
switch, and then pushing and releasing the
freeze push button switch.
