OPERATION

All air must be removed from the system. The Inline Pressure Boosting System comes with an air bleed valve installed to assist with evacuating the air.
1. Close all system outlets then open the air bleed valve.
2. Open any inlet valves to allow water supply to enter the pump. Be prepared for air mixed with some water to be discharged through the air
bleed valve. It may be handy to have a small bucket to catch the dispersed water.
3. Close air bleed valve once all the air has exited the system (indicated by a small, steady stream of water coming out of the bleed valve).
4. Once the air has been evacuated from the system, slightly open a system outlet valve. Start the pump by pressing the button.
This will put the pump into automatic mode.
5. Immediately begin opening a discharge valve to half open. If, after a few minutes of running, you do not get pressurized water,
repeat the priming process as detailed above.
NOTE: If the unit does not prime in 10 seconds, the pump will stop and the RED light will flash on the display. This is due to an
UNDERLOAD error condition in which the pump is not yet incurring a load indicating water is being pumped. Simply press the start button
again to allow the pump to run for an additional 10 seconds in order to prime. REPEAT this as necessary.
6. Once the pump is operating, fully open the discharge valve and a system outlet, letting the pump operate until the water is running clear.
No further priming should be needed unless the pump is drained or there is a leak in the suction plumbing.
NOTE: NEVER OPEN THE BLEED WITH THE PUMP ON as this may allow air to ENTER the pump rather than expel it from the system.
Effect of System Leaks
Leaking water systems may cause the Inline Pressure Boosting System to cycle more than expected. This is due to the unit turning on when the outlet
pressure drops below the preset discharge pressure (factory-set at 40 psi). Continuous running or a high number of starts and stops will not hurt the
controller, pump, or motor. The issue should still be fixed, if possible, to eliminate an increase in power usage of the system.
Adjusting/Fine-Tuning Inline 400 Performance
When installed properly with an external pressure tank (2-gallon size recommended), it is possible to adjust the pump CUT-IN pressure
of the Inline 400 unit.

WARNING
!
The Inline 400 pump is factory-set to start boosting (turn pump ON) when the discharge pressure drops below 40 psi. In certain applications, it may be
desirable to adjust this setting to be higher or lower. See the example below:
In this example, a home is supplied with pressurized water from the local
municipality that fluctuates between 30 psi MAX and 25 psi MIN. As stated
earlier, the Inline 400 will add 55 psi to the incoming water pressure.
Disconnect power to the unit before attempting to remove the control cap and adjust the discharge pressure switch.
MAX Total Downstream Pressure is 30 psi + 55 psi = 85 psi
MIN Total Downstream Pressure is 25 psi + 55 psi = 80 psi
