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
System 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 System 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 System Controller. Examine the next section to
become familiar with the System 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.
