Please read all instructions completely before you install or operate your new pump.

The motors used with the PCA Series pumps are high quality, industrial duty motors. Some are dual voltage motors, which can be operated at either

115 volt (low) or 230 volt (high). They have been tested at the factory before being shipped.

It is vitally important to supply proper voltage and amperage to the motor. Set the internal connections on your motor to match your supply line

voltage. If these do not match, you will damage the motor and void the warranty. DO NOT ATTEMPT TO WIRE THE MOTOR IF YOU DON'T KNOW

WHAT YOU ARE DOING!!! Have a qualified electrician do the work.

The following example shows how to wire a typical Baldor 1/4 HP, single phase, 1725 RPM motor (with the following diagram)

CONNECTIONS ABOVE GIVE CLOCKWISE ROTATION FACING LEAD END.

For low voltage:

1. Connect your incoming hot lead (normally the black wire) to the wires marked #1 and #3.

2. Connect your incoming neutral lead (normally the white wire) to the #4 wire.

3. Twist wires #2 and #J together.

4. Use appropriately sized wire nuts to insure all connections are secure and insulated.

5. Connect your incoming ground (normally green) to the green screw in the connection box.

For high voltage:

1. Connect your incoming hot lead (normally the black wire) to wire #1.

2. Connect your other hot lead (normally the white wire) to wire #4.

3. Connect wire #2 and #3 together.

4. Tape off the wire marked J.

5. Use appropriately sized wire nuts to insure all connections are secure and insulated.

6. Connect your ground lead (normally green) to the green screw in the connection box.

Note: Your motor may have a different wiring diagram. Follow its instructions for line placement.

PCA SERIES PUMP PLACEMENT CHART

When determining the placement of your PCA Series pump, two factors will be influenced by its height above water level. First, is its ability to self-

prime. To insure a reasonable prime time without the use of a swing type check valve (do not use spring loaded check valves), position the pump no

higher than the height shown in the "maximum recommended suction lift" column. Second, is its ability to maintain a prime and minimize cavitation.

Even with a swing type check valve, we do not recommend a pump be installed more than 9' above the water level.

Notes:

1. The data in this chart was compiled using 2" pipe, 10' in length. If you use larger pipe or have longer runs, it will increase the time required to prime.

2. All PCA Series self-priming pumps have been tested to operate up to a height of 9' above the surface of the water. Do not install your pump higher

than 9'.

3. If you use small pipe, more fittings, have longer runs, use strainers or in any other way make it harder for water to flow easily to the pump — it will

reduce your maximum recommended height and may increase the time to prime.
