1. Find the Maximum Acceptance for the installed
Well-X1 model.
2. Ensure the desired operating range does not exceed
that model’s Maximum Acceptance.
3. To enter the programming mode, press and hold the
■
button until
LO
appears. This is the cut-in setting.
Factory default will be 40 psi.
4. Use the
s
and
t
arrows to raise or lower the cut-in
setting. Adjustment can be made within 10 psig or as
wide as 55 psig of the cut-out setting to 60 psig. If this
range is exceeded, the display will cease to change
even though the button is being pressed.
Minimum setting is 10 psig.
PRESSURE ADJUSTMENT
The Well-X1
®
utilizes a simple cut-in/cut-out adjustment. Before setting the desired operating range, refer to the chart
below to ensure the Well-X1's Maximum Acceptance is not exceeded. Adjust the precharge as shown on page 9.
CAUTION!
Exceeding Maximum Acceptance will reduce tank life and cause irreparable damage.

5. To adjust the cut-out, depress
■
once and the display
will read

. Again, press the
t
or
s
buttons to raise
or lower the setting. The same 10-55 psig differential
range applies.
Maximum setting is 80 psig.
6. After adjusting the cut-in and
cut-out, release the buttons.
After a slight pause,
Pr
will be
displayed, indicating the settings
are saved in the event of a
power outage.
PRECHARGE ADJUSTMENT
Whenever the cut-in (LO) setting is changed, the tank
precharge must be adjusted. To do this, shut the Well-X1
off
and open the drain to empty all water. Using an air gauge,
adjust the precharge to 2 psig below the cut-in (LO) setting.
Failure to adjust the precharge will result in tank damage or
water interruption.
DANGER!
Explosion Hazard.
If the
Well-X1 has been in service and a
change to a higher pre-charge is necessary due to a
required change in the setting, failure to follow instruction
below can cause a rupture or explosion, possibly causing
serious or fatal personal injury, and/or property damage.
• Do not adjust or add pressure if there has been a loss
of air.
• Do not adjust the pre-charge pressure if there is visible
exterior corrosion.
• Do not adjust the pre-charge pressure if there has
been a reduction in pump cycle time or the pre-charge
pressure compared to its initial setting. This is because
reduction in pump cycle time can result from loss of
tank air pressure which in turn can mean there may
be internal corrosion and any re-pressurization or
additional pressure could result in rupture or explosion.
