This Product, like most Products under
pressure, may over time corrode. weaken and burst or
explode, causing serious or fatal injury, leaking or flooding
and/or property damage. To minimize risk, a licensed
professional must install and periodically inspect and
service the Product. A drip pan connected to an adequate
drain must be installed if leaking or flooding could cause
property damage. Do not locate in an area where leakage
of the tank or connections could cause property damage
to the area adjacent to the appliance or to lower floors of
the structure.
Chlorine & Aggressive Water: The water
quality can significantly influence the life of this Product.
You should test for corrosive elements, acidity, total
solids and other relevant contaminants, including chlorine
and treat your water appropriately to insure satisfactory
performance and prevent premature failure.
NOTE: Inspect for shipping damage and notify freight
carrier or store where purchased immediately if damage
is present. To avoid risk of personal injury and property
damage, if the product appears to be malfunctioning or
shows signs of corrosion, call a qualified professional
immediately. Current copies of the Product manual can be
viewed at www.amtrol.com. Use proper safety equipment
when installing.
ELECTROCUTION AND EXPLOSION HAZARD! Before
work is performed on the Product, turn off the power to the
Product and release all pressure in the system.
As in all plumbing products and water
storage vessels, bacteria can grow in this Product,
especially during times of non-use. Consult your local
plumbing professional regarding any steps you may wish
to take to safely disinfect your home’s plumbing system.
DANGER! EXPLOSION HAZARD, WHEN
THE WELL-X1™ HAS BEEN IN SERVICE AND A CHANGE
TO A HIGHER PRE-CHARGE PRESSURE IS NECESSARY
DUE TO A REQUIRED CHANGE IN THE PRESSURE SWITCH
SETTING, FAILURE TO FOLLOW INSTRUCTION MANUAL
CAN CAUSE A RUPTURE OR EXPLOSION, POSSIBLY
CAUSING SERIOUS OR FATAL INJURY, AND/OR PROPERTY
DAMAGE. • DO NOT ADJUST THE PRE-CHARGE PRESSURE
IF THERE HAS BEEN A REDUCTION OF THE 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, AND/OR PROPERTY DAMAGE.
RELIEF VALVE REQUIRED. A relief valve
has been installed which is set to open at excessive pressures
(100 psig or more). This will protect the Well-X1™ and other
system components should the pressure switch malfunction
and fail to shut the pump off. The relief valve is installed at
the connection of the Well-X1™ to the system piping.
Before attempting any service and
disassembly, shut off power to the pump. Ensure power
is disconnected prior to removing motor. Ensure power is
disconnected before cleaning is attempted.
This control is capable of running pumps
to pressures that may exceed the limitations of system
components. Never set the operation pressure higher than
that of the safe system capacity.
This control can be adjusted to a narrow
pressure differential. This can cause the pump to cycle
rapidly with an improperly sized tank, leading to pump
damage. This may require a larger pressure tank than
normally used.
CALIFORNIA PROPOSITION 65 WARNING:
This product contains a chemical known by the State of
California to cause cancer and to cause birth defects or
other reproductive harm. (California Installer/Contractor California law requires that this notice be given to consumer/
end user of this product.) For more information: www.
amtrol.com/prop65/htm
Every Well-X1™ is air tested to 125 psig,
the maximum working pressure for the Well-X1™.
The pump controller is not a disconnect.
The pump may be activated at any time. The electrical
system must be considered energized at all times unless
the circuit breaker is open. The disconnect for the controller
must break all incoming power lines. As with a mechanical
pressure switch, when installed with three wire 230 vac
pumps or any 3-phase pump, a standard pump motor
starter or a relay must be used.

3. COMPONENTS
The Well-X1™ combines all the standard well tank components in a single, easy to install package. The pressure tank,
control and tank fittings are factory-installed. After removing from the carton, inspect the Well-X1™ for damage and
ensure all components are present.

4. INSTALLATION AND SIZING CONSIDERATIONS
The Well-X1™ functions like a traditional pressure switch by cycling the pump on and off. The factory pressure settings
are 40 psi cut-in and 60 psi cut-out. The controller allows these settings to be adjusted to best suit the application. The
Well-X1™ can operate in two primary modes:

A. STANDARD OPERATION
Using a standard 20 psi differential, the Well-X1™ can be sized according to the chart below. In this
application, the sizing and performance will be similar to a traditional pressure tank and mechanical
switch combination.
B. CONSTANT PRESSURE MODE
The Well-X1™ control allows a narrow differential to provide consistent water pressure. The factory 20
psi differential can be reduced so the cut-in and cut-out pressures are within 10 psi. When installed as
a constant pressure system, the chart below should be used to ensure the tank volume is sufficient to
provide adequate cycle protection.
The maximum working pressure of the Well-X1™ is 125 psig. Do not
exceed the maximum working pressure.

5. INSTALLATION CONSIDERATIONS
LOCATION
The Well-X1™ is designed for indoor and outdoor installations. The NEMA 3R enclosure can be installed
in direct weather. If installed outdoors, be sure the following conditions are met:
• Do not install where ambient temperatures can drop below freezing
or exceed 120° F.
• Ensure a Tuf Kote™ model is selected (Example: WX1-302TK)
for outdoor installations. This proprietary coating is specifically
designed to withstand outdoor applications.
• Use water-tight: wiring conduit, wire nuts and conduit connections
as dictated by applicable codes and ordinances.
• Protect the piping from mechanical damage.
• Install the relief valve blow down tube where venting water will not
cause personal injury or damage the surrounding property.
• Drip Pan and Drain: To avoid leaking and/or property damage,
install with a drip pan connected to an adequate working drain
kept clear at all times.
ORIENTATION
Ensure the installation meets all applicable local codes and is installed by a qualified professional.
Additionally, the following should be noted.
• This unit is designed for vertical installation above ground only.
Do not install horizontally or directly bury the unit. The WellX1™ may be installed below grade in a well pit or other suitable
enclosure. Do not locate in an area where leaking or flooding
could cause property damage to surrounding areas.
• Check codes to determine if there are any height requirements
pertaining to the Well-X1™. Particularly, ensure the bottom
drain meets these requirements. If restrictions are imposed on
the proximity of drain connections to the floor, the unit may be
elevated on blocks or the bottom drain tube can be removed
and plugged, after which a sampling tap may be installed in the
water lines near the top of the Well-X1™.
