on your pump or in this manual, look for one of the fol- lowing signal words and be alert to the potential for per- sonal injury:

DANGER warns about hazards that will cause serious per-

sonal injury, death or major property damage if ignored.

WARNING warns about hazards that will or can cause se- rious personal injury, death or major property damage if ig-

nored. 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.

Electrical Safety

A WARNING

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

Ground pump before connecting to power supply.

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

_k Wire motor for correct

voltage. See "Electrical" section of this manual

and motor nameplate.

_k Ground motor before

connecting to power supply.

General Safety

Do not allow pump, pressure tank, piping, or any other sys- tem component containing water to freeze. Freezing may

damage system, leading to injury or flooding. Allowing pump or system components to freeze v_dl void warranty.

General Safety

WARNING

Hazardous pressure! Install pressure relief

valve In discharge pipe.

Release all pressure on system before working on any component.

Relief valve must be capable of passing full pump flow at 75 PSI.

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, tmclunered and properly lighted;

store properly all unused tools and equipment. Keep visitors at a safe distance from the work areas.

AWARNINGIPump body may explode if used as a

booster pump unless relief valve capable of passing full pump flow at 75 PSI (517 kPa) is installed.

[_ CAUTION]Motor normally operates at high temperature

and will be too hot to touch. ]t is protected from heat dam- age during operation by an automatic internal cutoff

switch. Before handling pump or motor, stop motor and allow it to cool for 20 minutes.

INTRODUCTION

We suggest you take a few minutes to read the instructions contained in this manual before installing and using your

pump. This viifi help you obtain the full benefits of the qual- ity and convenience built into this equipment. It will also help you avoid any needless service expense resulting from causes beyond our control which naturally cannot be cov-

eredinourwarranty.

RULES FOR SAFE INSTALLATION AND OPERATION

1. Read the Owners Manual and Rules for Safe Operation

and Installation Instructions careflifiy. Failure to follow these Rules and Instructions could cause serious bodily

injury, and/or property damage.

2. Check your local electrical wiring codes before installa- tion. ffyour local codes are not followed, your pump will not work to its full rated capacity. If in doubt, contact your local Power Company.

3. Be certain your pump installation meets all local plumb- hag, pump and well codes.

4. While installing the pump, always keep the well covered to prevent leaves and foreign matter from falling into the well and contaminating the water and/or causing possi- ble serious damage to the mechanical operation of the

pump.

5. Always test the well water for purity before using. Check with local health department for testing procedure.

6. Before installing or servicing your pump, BE CERTAIN pump power source is disconnected.

7. Be sure your pump electrical circuit is properly gruunded.

8. Complete pump and piping system MUST be protected against below freezing temperature. Failure to do so could cause severe damage and voids the Warranty.

9. Make sure the line voltage and frequency of the electrical circuit supply agree with the motor wiring. If motor is dual voltage type, BE SURE it is wired correctly for your power supply.

10. The correct fusing and wiring sizing is essential to proper

motor operation. Recommended flWmg and v/ire size data is in the manual.

INSTALLATION

NOTICE: Use Teflon tape supplied with the pump or Plasto-

Joint Stikl for making all pipe-thread connections to the

pump itself. To avoid stress-cracking, do not use pipe joint compounds on the pump.

1. Wrap male pipe threads being attached to pump with one or two layers of Teflon tape. Cover entire threaded por-

tion of pipe.

2. Do not overtighten threaded fittings in the plastic pump. Be sure you do not try to tighten joint past thread stop in

pump port!

3. If leaks occur, remove fittings, clean off old tape, rewrap

with one to two layers of tape and remake the connec-

tion. If joint still leaks, replace the fittings (fittings may be

undersized).

4. Be sure to support all piping connected to the System.

MAJOR COMPONENTS AND WHAT

THEY DO

Tank and Air Volume Control The tank serves two functions. It provides a reservoir of

water, some of which can be drawn through the house fix- ture before the pump must start, and it maintains a cushion

of air under pressure. When Captive Air + Tanks are used, no air volume control is

necessary. This tank contains a permanent pre-charge of air. When a Standard Tank is used, an air volume control adds

air to the tank when it is needed. See instructions included with Air Volume Control for details on installation and op-

eration. Pressure Switch

The pressure switch provides for automatic operation.

Impeller, Jet and Pressure Regulator The impeller of the pump rotates with the motor shaft, caus-

ing the water to fly out from its rim by centrifugal force. The rotation of the impeller creates a vacuum which "puns" in more water. Part of the water is diverted back to the jet

where it again passes through the nozzle and venturi - cre- ating additional vacuum to draw in more water and deliver-

ing it at high pressure to the impeller. In a deep well installation, the jet assembly is submerged

in the well because the vertical distance to the water level exceeds the suction lift of the pump.

Adjustment of the pressure regulator causes the fight amount of water to be diverted back to the jet for the most

efficient operation.

In a shallow well installation, the jet assembly is attached directly to the pump because the vacuum created will pull water to the pump.

The pressure regulator may be used to restrict the flow of water in a shallow well system if the SEARS convertible

pump produces more water than the well can produce.

DEEP WELL PUMP INSTALLATION

(Figures I & 2, Page 4)

In a deep well installation, the jet assembly is submerged in the well because the vertical distance to the water level ex-

ceeds the suction lift of the pump. A single pipe system must be used in 2" and 3" wells. A double pipe system must be

used in 4" or larger wells. Follow instructions packed with jet package for proper noz-

zle and venturi combination for your ptmaping depth.

DOUBLE PIPE JET

When a double pipe jet is selected, 2 pipes are used in the well. One is the suction pipe, and the other, the pressure

pipe. Plastic pipe is ideal for double pipe installations, due to its light weight mid easy installation.

Use 100 ponnd flexible plastic pipe on horizontal jet pumps.

TO INSTALL 4" DOUBLE PIPE JET

First, inspect jet to make sure no foreign matter has entered the openings.

Be certain no foreign matter enters pipe openings while in- stalling the unit.

Plastic Pipe Installations

1. Attach a foot valve (not furnished) to the jet with a short nipple.

2. Before installing, be certain foot valve operates freely.

3. A special plastic pipe adapter is included with the jet which screws into the 1-1/4" suction tapping over the

venturi.

4. Assemble a plastic pipe adapter (not furnished) into 1" tapping in the jet body.

5. Use sufficient length of plastic pipe to place the jet 10-15 feet below the lowest drawdown water level. This is the

level to which the water in the well will drop while being pumped continuously.

6. Tighten all hose clamps securely. A sanitary well seal is re- quired on top of the well casing. Use steel nipples and el- bows or specialized galvanized steel elbows to go through the well seat. Use plastic pipe adapters where special el-

bows are not used.
