START UP
BEFORE CONTINUING, CHECK FOR OPEN DRAIN VALVES OR
OTHER SOURCES OF FLOODING BEFORE STARTING UNIT.
1. Prime pump if necessary and adjust tank precharge to manufacturer’s
recommendation for intended pressure range. The factory WWDPC setting
is 40 psi cut-in and 60 psi cut-out.
2. Turn on power and ensure WWDPC display illuminates, “88” will appear,
then code revision number, then “00”. Display will blank momentarily and
the pump will start. If not, check installation.
3. The display will now read the current line pressure.
4. Allow the pump to reach the factory cut-off setting of 60 psi. IF THE PUMP
CANNOT REACH THIS SETTING, DISCONNECT POWER AND SEE THE
TROUBLESHOOTING SECTION ON PAGE 5.
5. Check for leaks and repair as necessary before proceeding.
6. Proceed to the ADJUSTMENT section.
NOTE: During the first 30 seconds after start up, the pump can be made to
operate manually by depressing the 5 arrow for 6 seconds. This is useful for
priming jet pumps.
DEVICE ADJUSTMENT (Entering Programming Mode)
NOTE: Differential pressure cannot exceed 55 psi or be less than 10 psi. If display
will not change, alter cut-in or cut-out to within 55 psi.
1. Press and hold . When “LO” appears, release. This will determine the
pressure at which the pump activates.
2. When number appears, tap 5 or 6 to change cut-in setting.
3. Press again. When “HI” appears, tap 5 or 6 to change cut-out setting.
This will determine the pressure at which the pump shuts off.
NOTE: Depressing a third time will display the last Error Code in memory (see
Error Code table in Troubleshooting section). If no errors have occurred, the
display will show “- -”
4. After approx. 10 seconds “Pr” will appear, indicating the settings are
programmed. Display will then revert to line pressure.
NOTE: The settings will now be stored until changed manually, even in the event
of power failure.
NOTE: If pump cannot reach cut-out setting within 5 minutes with no water
running, lower the pressure settings to fall within the pump’s pressure capabilities.
NOTE: Pressing 5 6 together for 3 seconds will rotate the screen 180 degrees.
This is useful if the control is mounted in an inverted position.
OPERATION
The WWDPC incorporates an accurate pressure sensing system capable of
maintaining the set pressure range without the need for regular service or
adjustment. The WWDPC controls the on/off cycling of the pump within the
selected pressure range (see ADJUSTMENT section).
The WWDPC also incorporates built-in diagnostic functions to protect the system
and alert the user or installer to potential problems. If a fault is found, an error
code will be displayed, indicating that service may be necessary. Error codes are
listed in the TROUBLESHOOTING section.

GENERAL SAFETY INFORMATION
WARNING: REVIEW ALL GENERAL SAFETY INFORMATION PRIOR TO INSTALLATION.
READ CAREFULLY THE PRODUCT INSTALLATION,
OPERATING AND MAINTENANCE INSTRUCTIONS. FAILURE
TO FOLLOW THE INSTRUCTIONS AND WARNINGS IN THE MANUAL MAY RESULT
IN SERIOUS OR FATAL INJURY AND/OR PROPERTY DAMAGE, AND WILL VOID
THE PRODUCT WARRANTY. THIS PRODUCT MUST BE INSTALLED BY A
QUALIFIED PROFESSIONAL. FOLLOW ALL APPLICABLE LOCAL AND STATE
CODES AND REGULATIONS, IN THE ABSENCE OF SUCH CODES, FOLLOW THE
CURRENT EDITIONS OF THE NATIONAL PLUMBING CODE AND NATIONAL
ELECTRIC CODE, AS APPLICABLE.
This product is used in conjunction with a system containing a
tank under pressure, which may over time corrode, weaken and
burst or explode, causing serious or fatal personal injury, leaking or flooding and/
or property damage. To minimize risk, a licensed professional must install and
periodically inspect and service the product and system. A drip pan connected
to an adequate drain must be installed if leaking or flooding could cause property
damage. Do not locate system in an area where leaking could cause property
damage.
EXPLOSION OR RUPTURE HAZARD. A relief valve must be
installed to prevent system pressure in excess of local code
requirement or maximum working pressure designated in the Product Manual,
whichever is less. Do not expose system to freezing temperatures or temperatures
in excess of 120 degrees. Failure to properly size the system or follow instructions
in the Manual may result in excessive strain on the system and may lead to
product failure, leakage, flooding and/or property damage.
This control is capable of running pumps to pressures that may
exceed the limitations of system components. Never set the
operating 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 is normally used.
ELECTROCUTION HAZARD. Must be installed by qualified
professional. First disconnect all electrical power before
attempting service. For your safety, the information in this Manual must be
followed to minimize the risk of electric shock, property damage or
personal injury.
A water test must be taken before installation of any water
treatment equipment. The water quality can significantly
influence the life of your system. 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.
Use only lead-free solder and flux for all sweat-solder
connections, as required by state and federal codes.

DANGER! EXPLOSION HAZARD. When the well tank 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 instructions 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 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.
• Do not install with components that are incompatible with the WWDPC.
This product can expose you to chemicals including lead,
which is known to the State of California to cause cancer and
birth defects or other reproductive harm. For more information go to
www.P65Warnings.ca.gov.
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. Please read the entire owner’s manual and
installation instructions before installing our new Water Worker® product. Save
all documents and manuals for future reference. Use proper safety equipment
when installing. You must comply with all plumbing and electrical codes.
