Franklin Electric INLINE CONSTANT PRESSURE SYSTEM El Manual Del Propietario página 7

INSTALLATION PROCEDURE WIRING
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 Listed fuse/Listed 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
fitting 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 fitting into the conduit hole
in front of the L1, L2 line connector (FIGURE 3).

6. Route supply wires through the conduit fitting into the
wiring chamber.
7. Connect the supply ground wire to the ground lug in the
wiring compartment.
NOTICE: The safety earth ground connection is marked at its
terminal using the .
8. Connect the supply 230 V wires to the screw terminal marked
L1 and L2. Supply should be 60 ºC (140 °F)/75 ºC (167 °F)
copper wires and the terminals should be tightened to a torque
of 12 in-lbs (1.35 Nm).
9. Replace the access panel and tighten the four lid screws. For
proper sealing, the lid screws should be tightened to a torque of
10 in-lbs (1.13 Nm).
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

OPERATION
RATINGS
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.
WA 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 flooded 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 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.
W A R N I N G FAILURE TO FOLLOW THIS Instruction may
result in heating of water, personal injury, pump damage, and or
property damage.
