SAFETY INFORMATION

Please read and understand this entire manual before attempting to assemble, operate or install the product.

SAFETY INFORMATION

DANGER

ELECTRICAL SHOCK HAZARD.

Always disconnect power source before performing any work on or near the motor or its connected load. If the power disconnect point is out-of-sight, lock it in the open position and tag it to prevent unexpected application of power. Failure to do so could result in fatal electrical shock.

ELECTRICAL SHOCK HAZARD.

Do not handle the pump with wet hands or when standing in water as fatal electrical shock could occur. Disconnect main power before handling unit for ANY REASON!

RISK OF ELECTRIC SHOCK.

These pumps have not been investigated for use in swimming pool areas.

WARNING

ELECTRICAL SHOCK ALERT.

Follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the Occupational Safety and Health Act (OSHA).

ELECTRICAL SHOCK ALERT.

Replace damaged or worn wiring cord immediately. Never use an extension cord.

ELECTRICAL SHOCK ALERT.

Do not kink power cable and never allow the cable to come in contact with oil, grease, hot surfaces, or chemicals.

ELECTRICAL SHOCK ALERT.

Wire motor to correct supply voltage. See motor nameplate and wiring diagrams and check voltage of power supply.

ELECTRICAL SHOCK ALERT.

Unit must be securely and adequately electrically grounded. This can be accomplished by wiring the unit to a ground metal-clad raceway system or by using a separate ground wire connected to the bare metal of the motor frame or other suitable means.

ELECTRICAL SHOCK ALERT.

Do not disassemble the motor housing. This pump has no repairable internal parts and disassembling may cause leakage or dangerous electrical wiring issues.

ELECTRICAL SHOCK ALERT.

Make certain the electrical power source is adequate for the requirements of the pump.

ELECTRICAL SHOCK ALERT.

Never use an extension cord with this pump.

CHEMICAL ALERT.

This product contains chemicals known to the state of California to cause cancer and birth defects or other reproductive harm.

HAZARDOUS PRESSURE ALERT.

Install pressure relief valve in discharge pipe. Release all pressure on system before working on any component.

EXPLOSION ALERT

Do not use to pump ammable or explosive uids such as gasoline, fuel oil, kerosene, etc. Do not use in ammable and/or explosive atmospheres.

SAFETY INFORMATION

CAUTION

PRODUCT DAMAGE MAY RESULT

This pump is not to be used for irrigation or water systems.

PRODUCT DAMAGE MAY RESULT

Protect the power cable from coming in contact with sharp objects.

PRODUCT DAMAGE MAY RESULT

Do not run pump dry.

PRODUCT DAMAGE MAY RESULT

Pump and plumbing must be full of water before startup.

PRODUCT DAMAGE MAY RESULT

Do not pump water which contains sand, mud, silt, or debris.

INJURY MAY RESULT

Be careful when touching the exterior of an operating motor. It may be hot enough to be painful or cause injury.

GENERAL PUMP INFORMATION

Typical Pump Setup Convertible jet pumps are designed for use in

these applications:

1. Shallow wells (0 - 25 ft. lift) where ejector bolts to pump.

2. Deep wells (0 - 40 ft. lift) where well inside

diameter is 4 in. or more and ejector is installed in the well.

GENERAL PUMP INFORMATION

Ventilation - Ventilation and drainage must be provided to prevent damage to the motor from heat

and moisture. Freezing - Pump and all piping must be protected from freezing. If freezing weather is forecast, drain pump or remove completely from the system. Water Supply - The water source must be able to supply enough water to satisfy the capacity of pump and water needs. See performance chart on page 2. Suction Lift - Suction lift is the vertical distance from the lowest level of the water to the pump intake. See performance chart on page 2. Horizontal Distance - The horizontal distance is the horizontal measurement between pump suction and the water source. This distance may affect the ability of pump to operate. If it is more than 100 ft., call the manufacturer for assistance 1-800-742-5044.

Pipe And Fittings

3. Use galvanized steel or NSF PW Schedule

40 PVC pipe and ttings. This material is

designed for water pressure and will seal against air and water under pressure. Do

not use DWV ttings, as these are designed

for drains without pressure and will not seal properly.

CAUTION: The entire system must be

air and water tight for efcient operation and to

maintain prime.

Wire Size:

The wire size is determined by the distance from the power source to the pump motor and the horsepower rating of the motor. See Table A for proper wire size.

WELL TO PUMP CONNECTION (SUCTION PIPE)

CAUTION: Dry-t entire assembly to ensure proper t before gluing or taping parts.

CAUTION: Follow all proper gluing procedures as specied by the glue manufacturer. Always

glue in a vertical direction whenever possible to prevent glue from dripping inside pipe or ttings

CAUTION: Use pipe tape and pipe paste compound on all male threads. Tighten with wrench to

a snug t and add another 1/4 turn to ensure proper seal.

Shallow Well Installations Only

1. Thread 1-1/4 in. male x 1 in. PVC adapter

(not included) into a 1-1/4 in. foot valve (not included). Hand tighten, then tighten 1/2 turn with a pipe wrench.

2. Using a 2-step PVC system (not included), attach enough PVC pipe and couplings to the adapter to equal the depth of the well, minus 5 ft.

3. Before sliding the pipe assembly into the

well, rmly clamp the assembly with a pipe

clamp (not included) to prevent the assembly from sliding down into the well.
