MAINTENANCE

This device is maintenance-free. In case of system maintenance,
review and understand the following safety warnings and product
instructions prior to performing any service.
Hazardous voltage.
Can shock, burn, or cause death.
Ground the device before connecting to
power supply. Disconnect power before
working on the device, pump, or motor.
Hazardous pressure.
Discharge the system before disassembling
the device.
WARNING
Before disconnecting the pump, be sure
the fuse box leads are disconnected or the power is turned off. After
reassembling the pump, refer to these instructions before running.
WARNING
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.

TROUBLESHOOTING

If the device and pump do not seem to be operating correctly
together by starting and stopping with water usage, first check
that the technical features of the flow controller and the pump
are compatible. Use the table and figures in this manual to
confirm compatibility.
The water supply to the device can be a municipal / utility water
main line, a stored water volume above the pump, or a suction
lift source like a well where the pump is above the water source
or submerged within. This allows the device to be used with both
surface mounted or submersible well pump product designs. For
suction lift or submersible water system applications the Inline pump
flow control's have a built in check valve, but proper suction line check
valve or foot valve placements are needed to ensure the system holds
water for priming and operation.
Waterhammer or hydraulic vibration:
Some installations with high water flow rates or excessive water
turbulence could experience waterhammer or hydraulic shock
vibrations. To mitigate these effects an additional 2 gallon (or larger
as desired) pressurized bladder expansion tank can be installed in
the discharge plumbing upstream from the pump/control device.
The air charge in this bladder tank should be set to match the system
working pressure.
Water System Plumbing Leaks:
All water leaks within the plumbing system should be corrected
for optimal performance of the system. If water leaks cannot be
corrected or mitigated, to prevent frequent pump starts, an additional
pressurized bladder expansion tank should be installed with an
internal water draw down capacity capable of supporting the pump
start frequency desired. The air pressure charge of this tank should be
set to roughly the same as the systems working pressure.
Waterwell systems with high static water levels or Systems with
high incoming pressure:
Some waterwell applications will be such that the water level in the
well will change dramatically over time or with use. If that is the
case there is an opportunity for the submersible well pump to create
high pressure when the water table is high (also called a high static
water level), but then the pressure will decrease as the water level
dynamically drops in the well. In this case the Inline Control devices
are rated to operate in high pressure installations of up to 174 PSI.
If the water supply pump produces greater than 174 PSI additional
pressure mitigation equipment, such as a pressure regualting valve,
may need to be installed on the inlet plumbing line feeding the Inline
Control device to prevent system damage.
