Electrical Safety

Wire motor for

correct voltage. See “Electrical” section of this manual and motor nameplate.

Ground motor before

connecting to power supply.

Meet National Elec-

trical Code, Canadian Electrical Code, and local codes for all wiring.

Follow wiring instruc-

tions in this manual when connecting motor to power lines.

Make workshops childproof; use padlocks and master switches; remove starter keys.

Do not touch an operating motor.

Modern motors are designed to operate at high temperatures. To avoid burns when servicing pump, allow it to cool for 20 minutes after shut-down before handling.

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

Carefully read and follow all safety instructions in this manual and on pump.

Keep safety labels in good condition. Replace missing or damaged safety labels.

General Safety

Pump is designed as a lawn sprinkler only. To avoid heat built-up, over pressure hazard and possible injury, do not use in a pressure tank (domestic water) system. Do not use as a booster pump; pressurized suction may cause pump body to explode.

Do not allow pump or piping system to freeze. Freezing can damage pump and pipe, may lead to injury from equipment failure and will void warranty.

Pump water only with this pump.

Periodically inspect pump and system components.

Wear safety glasses at all times when working on pumps.

Keep work area clean, uncluttered and properly lighted; store properly all unused tools and equipment.

Keep visitors at a safe distance from the work areas.

WARNING

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

Ground pump before connecting to power supply.

WARNING

Hazardous pressure! Do not run pump against closed discharge.

Release all pressure on system before working on any component.

NOTICE: Well must not be more than 20' depth to water.

1. Long runs and many fittings increase friction and reduce flow. Locate pump as close to well as possible: use as few elbows and fittings as possible.

2. Be sure well is clear of sand. Sand will plug the pump and void the warranty.

3. Protect pump and all piping from freezing. Freezing will split pipe, damage pump and void the warranty. Check locally for frost protection requirements (usually pipe must be 12" below frost line and pump must be insulated).

4. Be sure all pipes and foot valve are clean and in good shape.

5. No air pockets in suction pipe.

6. No leaks in suction pipe. Use Teflon tape or PlastoJoint Stik to seal pipe joints.

7. Unions installed near pump and well will aid in servicing. Leave room to use wrenches.

8. Pump body may explode if used

as a booster pump. DO NOT use in a booster application.

NOTICE: Use the installation method below which matches your well type.

CASED WELL INSTALLATION

1. Inspect foot valve to be sure it works freely. Inspect strainer to be sure it is clean.

2. Connect foot valve and strainer to the first length of suction pipe and lower pipe into well. Add sections of pipe as needed, using Teflon tape on male threads. Be sure that all suction pipe is leakproof or pump will lose prime and fail to pump. Install foot valve 10 to 20 feet below the lowest level to which water will drop while pump is operating (pumping water level). Your well driller can furnish this information.

3. To prevent sand and sediment from entering the pumping system, the foot valve/strainer should be at least 5 feet above the bottom of the well.

4. When the proper depth is reached, install a sanitary well seal over the pipe and in the well casing. Tighten the bolts to seal the casing.

5. When using a foot valve, a priming tee and plug as shown in Figure 5 are recommended.

DUG WELL INSTALLATION

Same as cased well installation.

DRIVEN POINT INSTALLATION

1. Connect the suction pipe to the drive point as illustrated in Figure 6. Keep horizontal pipe run as short as possible. Use Teflon tape on male pipe threads. Multiple well points may be necessary to provide sufficient water to pump.

2. Install a check valve in horizontal pipe. Flow arrow on check valve must point toward pump.

HORIZONTAL PIPING FROM WELL TO PUMP

1. Never install a suction pipe that is smaller than the suction port of the pump.

2. To aid priming on well point installations, install a line check valve as shown in Figure 6. Be sure check valve flow arrow points toward pump.

DISCHARGE PIPE SIZES

1. If increasing discharge pipe size, install reducer in pump discharge port. Do not increase pipe size by stages.

2. When the pump is set away from the points of water use, the discharge pipe size should be increased to reduce pressure losses caused by friction.

• Up to 100' run: Same size as pump discharge port.

• 100' to 300' run: Increase one pipe size.

• 300' to 600' run: Increase two pipe sizes.

LAWN SPRINKLING APPLICATION

This pump is designed for lawn sprinkling. It is designed to deliver plenty of water at full sprinkler pressure. It can pump from a pond, cistern or well points.

Pump discharge can be divided to supply two (2) or more sprinkler systems. A suggested multiple discharge to service is shown in Figure 7.

Do not use in a pressure tank or booster pump application.

PUMP INSTALLATION

NOTICE: Use only Teflon tape or Teflon based joint

compounds for making all threaded connections to the pump itself. Do not use pipe joint compounds on plastic pumps: they can react with the plastic in the pump components. Make sure that all pipe joints in the suction pipe are air tight as well as water tight.

If the suction pipe can suck air, the pump will not be able to pull water from the well.

1. Bolt pump to solid, level foundation.

2. Support all piping connected to the pump.

3. Wrap 1-1/2 to two layers of Teflon tape clockwise

(as you face end of pipe) on all male threads being attached to pump.

4. Tighten joints hand tight plus 1-1/2 turns. Do not

overtighten.

NOTICE: Install pump as close to well head as poss-

ible. Long piping runs and many fittings create friction and reduce flow.

NOTICE: For long horizontal pipe runs, install a priming tee between check valve and well head as shown in Figure 6. For driven point installations, install a check valve as shown in Figure 6. Be sure check valve flow arrow points toward pump.

Use schedule 80 or iron pipe. See “Well Pipe Installation” for more information.
