3. To adjust the cut-out, depress MODE once and the
display will read HI. 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.
4. 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.
