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.
A. Use high pressure reinforced type discharge
hose ONLY. See parts list for available hose, nozzle and fittings. A high pressure relief valve is recom­mended.
B. DO NOT use garden hose with H.P. 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 pump suction pipe pressure plus pump
discharge pressure does not exceed pressure rating of hose and fittings! See Table I for pump

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 1” or 1-1/4” high pressure hose to the pump inlet. A special heavy duty 1” or 1-1/4” suction hose with fittings is available as an accessory. If the pump is permanently mounted on wall, use a 1” or 1-1/4” pipe or heavy-duty hose for the suction line. 20 GPM models require a 1-1/4” discharge hose to reduce friction losses.

Page 6). If possible, connect pump to a separate branch circuit with no other appliances on it.
Wire motor according to diagram on motor
nameplate. If nameplate diagram differs from diagrams above, follow nameplate diagram.
For All 3-phase Motors: Follow the wiring
diagram on the motor junction box or on the motor nameplate.
Figure 5: Changing the Voltage Setting.
Figure 6: Motor Set for 115 Volt Operation.
* Models with power cords are pre-wired for 115 volts. This includes models MGP7C and MGP7D.
WIRING CONNECTIONS
1. Install, ground, wire and maintain this pump in
compliance with the National Electrical Code (NEC) or the Canadian Electrical Code (CEC) and with all local codes and ordinances that apply. Consult your local building inspector for local information.
2. Make sure that the voltage, frequency and phase
(single phase or three phase) of the power supply agree with that stamped on the motor nameplate. If in doubt, check with the power company.
3. Some models are equipped with three phase
motors. Three phase motors require magnetic starters and can run in either direction, depending on how they are connected to the power supply.
NOTICE: Dual voltage motors without cords are factory wired for 230 volts. If necessary, reconnect the motor for 115 volts, as shown. All cord connected motors are wired for 115 volts (see Page 6). Do not alter the wiring in single voltage motors.
Install, ground, wire, and maintain your pump in comliance with the National Electrical Code (NEC) or the Canadian Electrical Code (CEC), as applicable, and with all local codes and ordinances that apply. Consult your local building inspector for code information.
NOTICE: Clamp the power cable to prevent strain on the terminal screws.
NOTICE: Your Motor Terminal Board (under the motor end cover) looks like the board shown at left. Do not change motor wiring if line voltage is 230 volts. Connect power supply as shown for your supply voltage.

To Check For Proper Rotation – 3 Phase Motors
Risk of electrical shock.
1. Be sure power is disconnected to motor when working on electrical connections.
2. Remove the motor end cover, exposing motor shaft. Momentarily start pump. If hookup is correct, the shaft will rotate clockwise.
3. If rotation is not clockwise, reverse any two leads to the starter. The rotation will now be correct.
GROUNDING THE MOTOR
Ground the pump permanently using a wire of size and type specified by local or National Electrical Code.
Models with a factory installed cord and plug:
Risk of electric shock. This equipment
is only for use on 115V and is equipped with an approved 3-conductor cord and 3-prong, grounding­type plug. To reduce the risk of electric shock, be certain that it is connected to a properly grounded, grounding-type receptacle. Do not modify or remove the plug. Make sure the pump circuit meets the National Electrical Code. To avoid a dangerous electrical shock hazard, keep the cord dry at all times.
Models without a cord or plug:
1. Connect ground wire first. Connect the ground wire to the green grounding terminal provided under motor canopy (see Figure 5) identified as GRD. Make the ground connection to this terminal. Do not connect the motor to an electrical power supply until the unit is permanently grounded; otherwise a serious or fatal electrical shock hazard may be caused.
2. For the best ground connection, connect to a grounded lead in the service panel or to a metal underground water pipe or well casing at least 10 ft.
long. If a plastic pipe or insulated fittings are used, run the ground wire directly to the metal well casing or use a ground electrode furnished by the power company.
LUBRICATION
It is not necessary to lubricate the pump or the 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 the pump to replace the seal (See “Maintenance”, Pages 7 and 8).
OPERATION
NOTICE: Observe the following precautions when
operating the pump:
1. Keep the motor dry! Do not direct the stream from
pump discharge onto the motor!
2. pump with the discharge shutoff, as the hose may burst or the 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 the pump dry; to do so may damage the seal.
5. To avoid internal damage to the pump, Do not operate with water at temperatures above 175 degrees F.
