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 DC2 setting is 40 psi cut-in and 60 psi cut-out.

2.Turn on power and ensure DC2 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 DC2 incorporates an accurate pressure sensing system capable of maintaining the set pressure range without the need for regular service or adjustment. The DC2 controls the on/off cycling of the pump within the selected pressure range (see ADJUSTMENT section).

The DC2 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.
