Inline Constant Pressure System
FIGURE 4:
Adjusting Pump So System Demand Is Not More Than System Supply
Inline Systems are typically used to increase municipal water pressure anywhere from 10 psi (0.7
bars) to 70 psi (4.8 bars) above what is being supplied by the water utility. For the pump to operate
properly as it boosts the municipal water to the desired pressure, a consistent and steady flow of
water is required. The system will fail prematurely if it is set to operate at a point beyond what can
be supplied.
Process To Ensure Pump Is Receiving Enough Water To Meet Demand
1. Install a shut-off valve in the plumbing near the discharge of the pump.
2. Close the valve, but make sure that the supply water is allowed to freely flow into the pump
without restriction.
3. Adjust system for maximum flow demand.
4. Turn on the pump, and begin opening the discharge's shut-off valve.
5. Continue opening the discharge valve until a very distinct noise is heard coming from the
pump. This noise is called cavitation (which can destroy the pump over time), and will
sound like there is gravel inside the pump. STOP opening the discharge valve once
cavitation is heard.
6. Slowly close the discharge valve until the cavitation is no longer heard.
7. The pump is now adjusted so that the system demand will not exceed what can be
supplied.
8. If the supply pressure or water demand varies over time, this procedure may need to be
repeated to eliminate cavitation.

DRIVE DIP SWITCH OPTIONS

The Inline System is factory set to properly operate in most installations without needing any
adjustments or changes to the DIP switch settings. If changes are required, the following is a
description of what control logic changes will occur as a switch's position is changed.

modify DIP switch settings until power has been removed and 5 minutes
have passed for internal voltages to discharge! Power must be removed
for DIP switch setting to take effect.
