1. Disconnect electrical power at the main breaker.
2. Verify that the dedicated branch circuit for the Inline
System is equipped with a 15 amp circuit breaker.
3. Remove the access panel of the Inline System by
removing the four access panel screws as shown in
Figure 1.
4. For your convenience the pressure sensor has been
pre-wired inside the unit. The red and black wires are
attached to the pressure sensor inputs and the white and
green wires are connected to the pressure shut-off sensor
input (optional). See FigureS 3 AND 4 showing the
sensor connections.
5. If mounting or in wet environments, a liquid tight
conduit fi tting and liquid tight conduit are required |(not
supplied) to ensure that the enclosure maintains a water
tight, NEMA 4 rating. Install the liquid tight conduit fi tting
into the conduit hole in front of the L1, L2 line connector.

10. Set the pressure tank pre-charge at 70% of the
desired water pressure setting. To check the tank's pre-
charge, de-pressurize the water system by opening a tap.
Measure the tank pre-charge with a pressure gauge at its
infl ation valve and make the necessary adjustments.

C A U T I O N
Maximum operating pressure should be
limited to whatever level is needed to protect the rest of
the existing system plumbing. When required, a pressure
relief valve should be installed, and/or the optional over
pressure sensor can be used.
Maximum suction pressure is 70 psi (4.8 bar). Maximum
water temperature is 104 °F (40 °C). Avoid pumping
abrasive or sandy water.
W A R N I N G
Hazardous Pressure: Do not run pumps
against a closed discharge, or at a system operating
pressure above 145 psi (10 bar).
C A U T I O N
This pump has been evaluated for use
with water only.
PriMiNg
Never run the pump dry. Fill the suction pipe, pump
and discharge piping completely with water. A typical
installation will be supplied by either a tank or a
pressurized water source, creating what is known as
fl ooded suction condition.
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 fl ow (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.
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
