Starting
Close all system outlets, then slightly crack one system outlet to allow excess air to bleed out of
the system. Start the pump. Gradually, but immediately, begin opening the discharge valve to half
open. If after a few minutes of running you do not get water, repeat priming process (the pump
may be locked by excess air that is trapped in the unit). 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.
Leaky Systems
Leaky water systems might keep the controller running due to the accurate pressure sensing
capability of the pressure sensor. Continuous running or starts and stops do not hurt the controller,
pump or motor. However, to reduce the on-time of the controller/pump/motor, a "Bump-Mode"
procedure is installed.
During low flow (or leaky) conditions, this feature periodically increases the speed of the pump
several psi above the set point and shuts off the pump. This adds some time to bleed off before
the system starts up again
Water Supply Shut-off
Remove power from the Inline System, prior to shutting off the incoming water supply. When ready
to restart the system, first turn the incoming water supply back on, then reapply electrical power to
the Inline System.

WARNING WARNING
!
Pressure Drop
Although the pressure is constant at the pressure sensor, pressure drops may be noticeable
in other areas of the home when additional taps are opened. This is due to restrictions in the
plumbing and will be more pronounced the farther the taps are from the pressure sensor. This
would be true of any system, and if observed, should not be interpreted as a failure in the
performance of the Inline Constant Pressure System.
Adjusting the Pressure Sensor
The pressure sensor communicates the system pressure to the Inline Constant Pressure System.
The sensor is preset at the factory to 50 psi (3.4 bar), but can be adjusted by the installer using the
following procedure:
a. Remove the rubber end-cap (FIGURE 4).
b. Using a 7/32" Allen-wrench (provided), turn the adjusting screw clockwise to increase
pressure and counter-clockwise to decrease pressure. The adjustment range is between 25
and 80 psi (1.7 and 5.5 bar) (1/4 turn = approximately 3 psi (0.2 bar)).
c. Replace the rubber end cap.
d. Cover the pressure sensor terminals with the rubber boot provided (FIGURE 4).

FAILURE TO FOLLOW THIS instruction may result in heating of water,
personal injury, pump damage, and/or property damage.
