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.
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. The pressure sensor has been pre-wired inside the unit (red and black wires). Similarly, the
over-temperature switch is pre-wired (white and green wires). To install the optional over-
pressure (shut-off) switch, wire in series with the over-temperature switch. To do this, remove
one wire connected to the over-temperature terminals and connect to the wire from the
shut-off switch. Connect the other switch wire to the open terminal. See FIGURES 3 and 4
showing the sensor connections.
5. If mounting or in wet environments,
liquid-tight conduit fitting and liquid-tight
conduit are required (not supplied) to ensure
that the enclosure maintains a watertight
NEMA 4 rating. Install the liquid-tight conduit
fitting into the conduit hole in front of the L1,
L2 line connector (FIGURE 3).
