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.
