ELECTRICAL SAFETY

Some models of

pump are supplied with 3-connector grounding type cord. Connect only to properly grounded, GFCI protected outlet. Do not lift pump by electrical cord.

Pump is non-

submersible. Keep motor dry at all times. Do not wash motor. Do not immerse. Protect motor from wet weather.

If using extension

cord, use only UL approved indoor/outdoor,

3-wire, grounding type cord. Do not allow any part of cord or receptacle ends to sit in water or damp locations.

Unplug pump before servicing.

Burn Hazard. Do not touch an oper-

ating motor. Modern motors can operate at high

temperatures. To avoid burns when servicing pump, allow it to cool for 20 minutes after shut-down before handling.

Follow local and/or national plumbing and electrical codes when installing.

Hazardous Pressure. DO NOT run the pump with discharge shutoff, as hose may burst or pump may be damaged due to high temperatures.

READ AND FOLLOW SAFETY INSTRUCTIONS!

This is the safety alert symbol. When you see this

symbol on your pump or in this manual, look for one of the following signal words and be alert to the potential for personal injury:

DANGER warns about hazards that will cause serious personal injury, death or major property damage if ignored.

WARNING warns about hazards that can cause serious personal injury, death or major property damage if ignored.

CAUTION warns about hazards that will or can cause minor personal injury or property damage if ignored.

The word NOTICE indicates special instructions which are important but not related to hazards.

GENERAL SAFETY

To avoid risk of serious bodily injury and property damage, read safety instructions carefully before installing pump. Do not allow pump or any system component to freeze. To do so may damage system and will void warranty.

Risk of electric shock. To avoid fatal shocks, proceed as follows if pump needs servicing. A. Disconnect power to pump outlet box before pul-

ling pump cord plug. After plug is pulled, let pump cool for 20 minutes before attempting to work on it.

B. Take extreme care when changing fuses. To re-

duced chance of fatal electrical shocks, DO NOT

stand in water or put your finger in the fuse socket. C. Ground electrical outlet box. D. Use only Ground Fault Circuit Interrupter (GFCI)

protected grounded outlet for cord plug.

Never run pump dry. Running pump dry can damage

internal parts, overheat pump (which can cause burns to people handling or servicing pump), and will void warranty.

Do not pump chemicals or corrosive liquids with pump.

Hazardous Pressure.

A. Use high pressure reinforced type discharge

hose ONLY. See parts list for available hose, nozzle

and fittings. A high pressure relief valve is

recom-mended. B. DO NOT use garden hose with High Pressure

Booster pump. Garden hose will not stand the

discharge pressure produced and will fail. C. High pressure discharge stream is dangerous. To

avoid injury, DO NOT aim the discharge stream at

any person or animal. D. 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.

WARNING

Hazardous voltage. Can shock, burn, or cause death.

Ground pump before connecting to power supply.

INSPECT THE SHIPMENT

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.

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. A special heavy duty 3/4" or 1" suction hose with fittings is available as an accessory. If pump is permanently mounted on wall, use a 3/4" or 1" pipe or heavy-duty hose for suction line. 20 GPM models require one-inch discharge hose to reduce friction losses and 30 GPM models require 1-1/4".

Hazardous pressure. Pump body may

explode if pressures exceed rated limits. Maximum

inlet pressure is 80 PSI. Maximum discharge pressure is 315 PSI. Warranty is void if these pressure limits are exceeded.

TABLE I - DISCHARGE PRESSURE

*For total discharge pressure, add this pressure to suction pipe pressure. For example, an HP7C pump taking suction from a 100

psi water service line will produce 130 + 100 = 230 psi total discharge pressure at 0 GPM flow. If suction pressure drops to 50 psi, discharge pressure will drop to 180 psi.

NOTE: Model numbers that include an “S” (HPS7C, HPS10D, etc) have a stainless steel suction, discharge assembly, and capscrews. Model numbers ending in “3” (HP7C3, HPS10C3, etc) have 3-phase motors. Models numbers ending in “T” have TEFC motors.

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:

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 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”, Pages 8 to 9).

OPERATION

NOTICE: Observe the following precautions when

operating the pump:

1. Keep the motor dry! Do not direct stream from

pump discharge onto the motor!

2. Hazardous pressure. 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. These are available as accessories and are

provided with three nozzles. The smallest nozzle

restricts the flow, allowing use of a smaller water

source. The two larger nozzles are used if the water

source will supply the pump’s full capacity.

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.

MOTOR SWITCH SETTINGS

Dual-voltage motors (motors that can 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.

PLUG TYPE VOLTAGE SELECTOR

To change to 115 volts:

1. Make sure power is off.

2. Pull the plug straight up.

*Models with power cords are pre-wired for 115 volts. This includes models HP7D-02 and HP7C-02.

3. Move and attach the plug at the 115 volt position. The plug will now cover 2 metal tabs. The arrow on the plug will point to 115V.

4. Attach the power lead wires to the power lead terminals. Make sure the wires are secure.

5. Attach the ground wire to the green ground screw

6. Reinstall the Motor end cover

Go to Wiring Connections below.

DIAL TYPE VOLTAGE SELECTOR

To change to 115 volts:

1. Make sure power is off.

2. Turn the dial counter-clockwise until 115 shows in the dial window.

3. Attach the power lead wires to the power lead terminals. Make sure the wires are secure.

4. Attach the ground wire to the green ground screw

5. Reinstall the Motor end cover

Go to Wiring Connections below.

Disconnect power before working on pump, motor, pressure switch, or wiring.
