NOTE: 1 psi = 0.068 bar
The Inline System needs a small pressure tank placed on the
pump outlet to maintain constant pressure. The tank supplies
water while the pump ramps up to speed and in circumstances
where only a small amount of water is required for a short period
of time. In addition, the tank prevents water hammer by acting
as a system buffer. This buffer also helps to prevent pressure
spikes when there is a sudden change in demand.
For 12 gpm (45 lpm) flow or greater, minimum pressure tank size
is 4 gallons (15 L); for 12 gpm (45 lpm) flow, minimum pressure
tank size is 2 gallons (7.5 L).
Pressure Tank Pre-charge (PSI)
The pressure tank pre-charge setting should be 70% of the system
pressure sensor setting as indicated in the preceeding table.
NOTE: Tank pre-charge should be maintained for optimum
pressure regulation.
W A R N I N G Pressure tank failure may prevent the pump
from shutting off. A run-on condition can heat the water in the
pump, which may cause pump failure, plumbing failure, and/or
personal injury.
W A R N I N G Failure to install a pressure tank will prevent the
pump from shutting off. FAILURE TO FOLLOW THIS WARNING
may result in heating of water, personal injury, pump damage,
and/or property damage.
INSTALLATION
NOTICE: READ AND FOLLOW ALL INSTRUCTIONS.
W A R N I N G Hazardous voltage can shock, burn or cause
death.
C A U T I O N Improper wiring can result in permanent
damage to the system. Pump connection must comply with
National Electric Code (NEC) or Canadian Electric Code (CEC),
and all applicable local codes.
C A U T I O N If you are not sure of the proper electrical
connections, employ a competent electrician for the
installation. This ensures the installation complies with all noted
electrical codes.
Disconnect power at electrical panel before making any
electrical connections. Supply voltage must be
+/- 10% of Inline System nameplate voltage (230 V).
Low or high voltage can damage the Inline System and will void
the warranty. Connect pump to dedicated branch circuit with no
other appliances on it.

INSTALLATION PROCEDURE PLUMBING

1. Disconnect electrical power at the main breaker.

28 2. Drain the system (if applicable).
32
3. Mount the Inline System in the desired location
35
using mounting screws. Screw locations are shown in FIGURE
39 1. The Inline System may be installed in
42 any orientation.
46 4. Install inlet and outlet plumbing and pressure tank as shown
in FIGURE 2. A check valve must be installed in the inlet and
49
outlet plumbing. The outlet check valve should be between
53
the pump and the pressure tank to prevent the possibility of
56
backflow in to public water systems, and to ensure proper
system operation. The inlet check valve should be used when
no other backflow prevention device is present. This inlet check
valve should be installed before the optional bypass loop if
that plumbing is used. Franklin Electric recommends that all
system check valves be spring-loaded to provide best system
performance. Be sure to check all local plumbing codes to
ensure that all requirements pertaining to backflow prevention
are met.
prevent the pump from shutting off. FAILURE TO FOLLOW
THIS WARNING may result in heating of water, personal injury,
pump damage, and/or property damage.
5. Install the pressure sensors at the pressure tank tee
downstream of the pressure tank. (The pressure tank should
be between the pressure sensor and the pump.) The pressure
sensor has a 1/4-18 National Pipe Thread (NPT) connection.
The pressure sensor should not be installed in an inverted
orientation (upside down). Make sure the pressure sensor and
tank are not located more than 5 feet off the main piping.
6. Install a pressure relief valve downstream of the check valve.
The discharge must be plumbed to a drain rated for maximum
pump output at relief pressure setting.
Do not operate pump unless pump is grounded.
A fused disconnect switch or circuit breaker should

very high pressure in some
situations. Always install a
pressure relief valve able to
pass full pump flow at 100
psi (6.9 bar). Install the
pressure relief valve near the
pressure tank.
W A R N I N G
Serious or fatal electric shock may result from failure to connect the Inline
System to the service entrance ground. Also ground metal plumbing
and all other metal near the Inline System. When grounding these
components, use a wire no smaller than the power supply wires from the
circuit breaker to the Inline System. To reduce the risk of electric shock,
disconnect power before working on or around the water system.
CAPACITORS INSIDE THE INLINE SYSTEM CONTROLLER CAN
STILL HOLD LETHAL VOLTAGE EVEN AFTER POWER HAS BEEN
DISCONNECTED. ALLOW 5 MINUTES FOR DANGEROUS INTERNAL
VOLTAGE TO DISCHARGE BEFORE REMOVING ACCESS PANEL.
This pump has not been investigated for use in swimming pool or
marine areas.
