Inline Constant Pressure System

Underload Sensitivity Selection
The Inline System controller is configured at the factory to ensure detection of underload faults in
a wide variety of pumping applications. In rare cases, this trip level may result in nuisance faults. If
the underload switch is activated, it is best to observe the system’s behavior during the underload
condition to be sure it will perform as expected. Once the controller begins to regulate pressure,
check operation at several flow rates to make sure the default sensitivity does not induce nuisance
underload trips.
If it is necessary to adjust the underload sensitivity, remove power and allow the controller to
discharge. Wait 5 minutes to allow internal voltage to dissipate, locate the DIP switch bank.
Use a small screwdriver (provided) to move position 1 to “ON” as shown.
Steady Flow Selection
The Inline System is configured at the factory to ensure quick response to maintain constant
pressure. In rare cases (as with a water line tap before the pressure tank), the unit may need to
be adjusted to offer better control. If the unit is used on a system that has a water line tap before
the pressure tank or where audible speed variations of the pump can be heard, adjusting the
pressure control response time may be necessary. After enabling this feature, the installer should
check flow changes for possible overshoot. A larger pressure tank and/or wider margin between
regulation and valve pressure may be required as the steady flow feature reduces the controller’s
reaction time to sudden changes in flow.
If it is necessary to adjust the pressure control, remove power and allow the controller to
discharge. Wait 5 minutes to allow internal voltage to dissipate, locate the DIP switch bank.
Use a small screwdriver (provided) to move position 2 to “ON” as shown.
MAINTENANCE
Lubrication
The pump requires only water for lubrication and must never be run dry.
Before disconnecting pump, be sure fuse box
leads are disconnected or power is turned off.
After reassembling the pump, refer to priming
instructions before running.
Hazardous voltage can shock, burn or cause
death. Disconnect power to pump before
servicing unit.
Draining
NOTICE:
Disconnecting the pump will not necessarily drain all other
parts of the piping system. If there are any concerns with the proper
procedure or necessity of draining the suction plumbing, contact a
water systems professional.
All piping and water tanks exposed to freezing weather should be drained. If there are any
concerns with the proper procedure to drain the system’s pressure tank, contact the tank
manufacturer for assistance.
