CALIFORNIA PROPOSITION 65 WARNING

WARNING
This product and related accessories contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.

GENERAL SAFETY

1. Carefully read and follow all safety instructions in this manual and on the unit itself.

2. Follow all applicable local and state codes and regulations.

3. WARNING
   RISK OF EXPLOSION Do not ground to a gas supply line.

   • Use high pressure reinforced type discharge hose ONLY. See parts list for available hose, nozzle and fittings. A high pressure relief valve is recommended.
   • DO NOT use garden hose with High Pressure Booster pump. Garden hose will not stand the discharge pressure produced and will fail.
   • High pressure discharge stream is dangerous. To avoid injury, DO NOT aim the discharge stream at any person or animal.
   • BE SURE that the pump suction pipe pressure plus the pump discharge pressure does not exceed the pressure rating of hose and fittings. See Table I for pump discharge pressure ratings.

4. RISK OF FIRE AND EXPLOSION

   • Can cause severe injury, property damage or death. To avoid risk of fire and explosion, pump water only with this pump. Do not pump flammable liquids or chemicals. Do not use the pump near gas pilot lights or where chemical or gas fumes are present. Use of an electric pump with liquids other than water or in an atmosphere containing chemical or gas fumes may ignite those liquids or gases and cause injury or death due to an explosion and/or fire.

5. RISK OF BURNS
   Never run the pump dry. To do so can damage internal parts, overheat pump (which can cause burns to people handling or servicing pump), and will void warranty.

   • If water is trapped in the pump during operation it may turn to steam. Trapped steam can lead to an explosion and burns. Never run the pump with the outlet closed or obstructed.
   • Do not touch an operating motor. Modern motors can operate at high temperatures. To avoid burns when servicing the pump, allow it to cool for 20 minutes after shut-down before handling.

ELECTRICAL SAFETY

RISK OF ELECTRIC SHOCK. Can shock, burn or kill. Ground the pump before connecting to a power supply. Disconnect the power before working on the pump, motor or tank.

• The pump is non-submersible. Keep the motor dry at all times. Do not wash the motor. Do not immerse. Protect the motor from wet weather.
• Disconnect the power to the pump before servicing the pump. After the power is disconnected, let the pump cool for 20 minutes before attempting to work on it.
• Take extreme care when changing fuses. To reduce the chance of fatal electrical shock, DO NOT stand in water or put your finger in the fuse socket.
• Ground the electrical outlet box.

PRODUCT INSPECTION

The high pressure booster pump has been carefully inspected and packaged to assure safe delivery. Inspect the pump and fittings and report to the carrier any items which are damaged or missing.

TABLE I – DISCHARGE PRESSURE

GPM

HP

| ****

NO. OF STAGES

| DISCHARGE PRESSURE PSI AT RATED FLOW| DISCHARGE PRESSURE PSI AT NO FLOW
---|---|---|---|---
10| 1/2| 6| 74| 113
10| 3/4| 8| 97| 147
10| 1| 10| 134| 188

*For total discharge pressure, add this pressure to suction pipe pressure. For example, a 1 HP pump taking suction from
an 80 psi water service line will produce 188 + 80 = 268 psi total discharge pressure at 0 GPM flow. If suction pressure drops to
50 psi, discharge pressure will drop to 238 psi at 0 GPM flow.

INSTALLATION

The pump is designed to boost city water pressure or water pressure from a private water system. Use this high pressure stream to wash down milk parlors, barns, garages and driveways, or for fire protection. The pump is portable with a convenient carrying handle. If an existing pressure water system is to be used as a water supply, it can be connected with available fittings and 3/4” or 1” high pressure hose to the pump inlet. If pump is permanently mounted on wall, use a 3/4” or 1” pipe or heavy-duty hose for suction line.

WARNING
RISK OF EXPLOSION. Do not ground to a gas supply line. Pump body may explode if pressure exceeds rated limits. Maximum inlet pressure is 80 PSI. Maximum discharge pressure is 315 PSI. Warranty is void if these pressure limits are exceeded.

HIGH PRESSURE BOOSTER PUMP INSTALLATION INSTRUCTIONS
These instructions cover high pressure booster pump installations as shown here.

To reduce friction losses to a minimum, inlet (suction) line should be short and have as few elbows as possible. Size the inlet according to the chart below:

AVE. GPM

| THREADED INLET SIZE| RECOMMENDED INLET LINE SIZE| RECOMMENDED DISCHARGE LINE SIZE
---|---|---|---
10| 3/4” NPT| 1”| 1”

An inlet strainer will prevent suspended debris from clogging pump.
The internal running surfaces of the pump and seals require water lubrication for good, consistent operation. Allowing pump to run dry or with no flow will severely damage pump and seals. Install a pressure gauge in pump inlet line.
Keep at least two pounds per square inch pressure (2 PSI) in inlet line whenever pump is operating. If this is not possible, consult customer service representative.

LUBRICATION
It is not necessary to lubricate pump or motor. The motor is equipped with sealed ball bearings, lubricated for the life of the bearing. The mechanical shaft seal in the pump is self-lubricating and requires no adjustment. Disassemble pump to replace seal, see Maintenance.

OPERATION
Observe the following precautions when operating the pump:

1. Keep the motor dry! Do not direct stream from pump discharge onto the motor.
   WARNING

2. RISK OF EXPLOSION. Do not ground to a gas supply line. Do not run the pump with discharge shutoff, as hose may burst or pump may be damaged due to high temperatures.

3. Do not use a standard trigger gun with this pump. Use only trigger guns with an automatic weeping feature.

4. Do not run pump dry; to do so may damage the seal.

5. To avoid internal damage to pump, do not operate with water temperature above 175 degrees F.

WARNING
RISK OF ELECTRICAL SHOCK. Can shock, burn or kill. Disconnect power before working on pump, motor, pressure switch, or wiring.

MOTOR SWITCH SETTINGS
Dual-voltage motors which ca operate at either 115 or 230 volts are set at the factory to 230 volts. Do not change motor voltage setting if line voltage is 230 volts, or if you have a single voltage motor.

NOTE
Never wire a 115 volt motor to a 230 volt line.

REMOVE MOTOR END COVER
If you have a dual-voltage motor, and will connect it to 115 volts, follow the procedure below.

You will need to remove the motor end cover to change the voltage setting. Your motor terminal board (located under the motor end cover) should look like one of those below.
