Refer to the included Inline System’s performance tables
(Appendix 1) and friction loss tables (Appendix 2) to
determine the amount of head lost for a given application.
PRESSURE TANK
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: Check tank pre-charge regularly to maintain
optimum pressure regulation.
INSTALLATION
NOTICE: READ AND FOLLOW ALL INSTRUCTIONS.
WARNING
Hazardous voltage can shock, burn or
cause death.
CAUTION
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.
CAUTION
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 (230V).
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.

Do not operate pump unless pump is grounded.
A fused disconnect switch or circuit breaker should
be placed at or near the pump as required by local
electrical codes.
INSTALLATION PROCEDURE PLUMBING
1. Disconnect electrical power at the main breaker.
2. Drain the system (if applicable).
3. Mount the Inline System in the desired location
using mounting screws. Screw locations are shown in
FIGURE 1. The Inline System may be installed in
any orientation.
4. Install inlet and outlet plumbing and pressure tank as
shown in
FIGURE 2. A check valve must be installed
in the inlet and outlet plumbing. The outlet check valve
should be between the pump and the pressure tank to
prevent the possibility of 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. Be sure to check all local plumbing
codes to ensure that all requirements pertaining to
backflow prevention are met.
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.
WARNING
Inline systems can develop 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.
WARNING
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.
