Installation
INSTALLATION PROCEDURE FOR
SUBMERSIBLE PUMP APPLICATIONS
(See Figure 1)
1. Disconnect the electrical power at the main circuit
breaker.
2. If there is water in the system, drain it.
3. The system requires a pressure tank; for best pressure
regulation, use a 6 gallon tank or larger. You can also
use an existing tank of much larger capacity. Set the
tank pre-charge at 70% of the set-point pressure (42
psi when the Control is set at 60 psi). See Table 1,
Page 5.
4. Install the pressure transducer in a tank tee or in a tee
in the water main downstream from the tank and less
than 10 feet from it. Do not install any elbows
between the tank and the pressure transducer. The
control includes a 10 foot length of cable to connect
the transducer to the control.
NOTE: If you have a pressure gauge in the system,
make sure that the gauge and the transducer are on
the same level. If the gauge is higher or lower than
the transducer, the gauge pressure will not match the
transducer's signal. The Control will, of course,
always be governed by the transducer's signal.
5. The Control weighs about 20 pounds. Mount it on a
solid support with two mounting screws.
NOTE: Mount the NEMA 4 control box with the
wiring ports down to protect the interior from dust
and rain. Leave at least 4" of clearance to the front
and sides of the box for heat radiation. To maintain
the NEMA 4 rating, you must use liquid-tight conduit
for all connections to the Control.
NOTE: Allow access to the 115V or 230V 1ø electri-
cal supply wiring and to the submersible motor
wiring. Use only copper wire rated at 60° C.
Maximum wire length between the Control and the
pump motor will depend on the motor used, but must
meet National Electrical Code (NEC) requirements
(See Page 7).

WIRING CONNECTIONS

(See Figure 2)
NOTE: The input wiring to the Control must meet NEC
requirements for a 115V or 230V/50 or 60Hz/1ø circuit
carrying 16 amps. For correct wire sizing from the
Control to the motor, consult your motor manufacturer
and the NEC.
Hazardous voltage inside Control; can
shock, burn, or kill. Capacitors inside the Control will
hold lethal voltage (up to 380 volts) even after power
has been disconnected. After disconnecting the power,
allow 5 minutes for the capacitors to discharge before
removing the Control cover. The ground terminals in the
Control must be connected to the motor, metal plumb-
ing, or other metal near the motor, using a wire at least
as large as the motor cable wires as shown in Figure 2.
Disconnect the incoming power before working on or
around the system.
NOTE: The pressure transducer is pre-calibrated; no
adjustment is needed.

Figure 2: Ground the Control as shown for safety and to
prevent current imbalance (ground loops) between con-
trol, motor, and transducer.
1. Power must be off at the main circuit breaker.
2. Make sure that the dedicated branch circuit for the
Control is protected by a 20 amp circuit breaker.
3. Remove the Control cover; feed the wires through the
appropriate conduit hubs and into the Control.
Connect them to the terminal blocks as shown in
Figure 2. To maintain the NEMA 4 rating of the Control
Box, all wiring must be run to the Control in liquid-
tight conduit and must run into the Control through
liquid-tight connectors (included with the Control).
