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.
