TANK TO HOUSE CONNECTION
1. Most pressure tanks will have a 1 inch inlet elbow
on the bottom. Connect to this elbow with a 1 in.
MPT x 1 in. slip (glue) adapter and short piece of
pipe (Fig. 1).
2. Install a 1 inch elbow (Fig. 2).
3. Attach a 1 in. slip (glue) x 3/4 in. FPT adapter and
3/4 in. MPT x 3/4 in. slip (Fig. 3).
4. Install a 3/4 in. union (optional) and continue with
pipe and 3/4 in. x 3/4 in. x 3/4 in. tee (Fig. 4).
5. Make the connection to the house plumbing.
From the tee, install pipe (Fig. 5) and shut off
valve (optional).
6. Completed installation with piping and tank is shown
(Fig. 6).
7. Optional tank-mounted system is shown.
Connections are basically the same as explained in
previous steps. (Fig. 7)

WIRING DIAGRAM
Wiring The Pressure Switch
1.CAUTION: Make certain that the power source matches the pump requirements. This pump can
run on 115V or 230V. See pump label for voltage prewired at the factory. (Fig. 1)
NOTE: To change Pump voltage, see wiring diagram on this page or step-by-step instructions on
page 11.
Your pump motor has a built-in thermal overload that protects the motor against burnout from
overload of low voltage, high voltage, and other causes. The device is automatic and resets itself
once the temperature has dropped to a safe point. Frequent tripping of the device indicates trouble
in the motor or power lines and immediate attention is needed.
CAUTION:
All wiring should be performed by a qualified electrician in accordance with the
National Electric Code and local electric codes. Connect the pump to a separate electrical circuit with
a dedicated circuit breaker. Refer to the Wire Size Chart for proper fuse size. Protect the power cable
from coming in contact with sharp objects. Make certain that the power source matches the pump
requirements. This pump has a dual voltage motor and can run on 115V or 230V. 1/2 HP pumps are
wired from the factory to run on 115V. 1 HP pumps are wired from the factory to run at 230V.
WARNING: The pump must be properly grounded using the proper wire cable with ground.
Always disconnect pump from electricity before performing any work on the motor.
Under-size wiring can cause motor failure and even fire. Use proper wire size specified in the Wire
size chart. Replace damaged or worn wiring cord immediately. Do not kink power cable and never
allow the cable to come in contact with oil, grease, hot surfaces, or chemicals.
