SAFETY INFORMATION

IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS: For optimal performance and

operation, read these instructions carefully before installing your new pump. This manual provides valuable guidance and instructions that should be followed to perform installation, operation and maintenance procedures for this product. It should be kept near the installation for immediate reference. Record nameplate data from your new pump on the blank template located in “Maintenance” on Page 7 for future reference.

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 injur y.

warns about hazards that will cause serious personal

injury, death or major property damage if ignored.

warns about hazards that can cause serious personal

injury, death or major property damage if ignored.

warns about hazards that will or can cause minor

personal injury or property damage if ignored.

GENERAL SAFETY

Risk of explosion. The pump body may explode if used to boost pressure above the pressures noted on Page 3. Do not use this pump with inlet pressure greater than 70 psi (483 kPa)or less than 3 psi (20.7 kPa). If not already in the piping system, install a pressure relief valve in the pump discharge line capable of passing the full pump flow at maximum rated pressure. If local code requires installation of a pressure relief valve capable of handling the full pump flow at a pressure less than 100 psi (689 kPa), follow the code requirements.

Risk of fire or explosion. To avoid risk of fire and explosion, pump water only with this pump. Do not pump salt water, flammable liquids or chemicals. Do not use the pump near gas pilot lights or where chemical or gas fumes are present. Use of an electric pump with liquids other than water or in an atmosphere containing chemical or gas fumes may ignite those liquids or gases and cause injury or death due to an explosion and/or fire. Pump approved liquids only with this pump.

Risk of burns. If water is trapped in the pump during operation it may turn to steam. Trapped steam may cause an explosion resulting in injur y or property damage. Never run the pump with the outlet closed or obstructed.

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

The hazards stated in this manual are not all-inclusive. To minimize the risk of hazard, it is strongly recommended that installation, operation and maintenance be performed by a qualified professional in accordance with local codes and standards for safe operation.

CALIFORNIA PROPOSITION 65 WARNING

This product and related accessories contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.

ELECTRICAL SAFETY

Risk of electric shock. Can shock, burn or kill. All

wiring should be done by a qualified electrician.



Wire motor for correct voltage. See “Installation” section (refer to page 5) of this manual and motor nameplate.



Ground motor before connecting to power supply.



Follow wiring instructions in this manual when connecting motor to power lines.



A complete power disconnect switch must be incorporated in the fixed wiring.



Install, ground, wire and maintain your pump in compliance with all applicable national and local codes and ordinances. Consult your local building inspector for code information.

Risk of freezing. Do not allow pump, piping, or any other system component containing water to freeze. Freezing may damage system, leading to injur y or flooding. Allowing pump or system components to freeze will void the warranty.

NOTICE only service agent or qualified person should replace power cord to avoid injury.

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.

ORDERING REPLACEMENT PARTS

Locate the Pentair Sta-Rite* nameplate on pump. This plate is normally on the pump case or bracket (seal plate). To ensure receipt of correct parts, provide all nameplate data when ordering. Catalog number is most important to reference. Write the nameplate information below, as nameplates can become worn or lost.

INSTALLATION

GENERAL CONSIDERATIONS

Before installing your submersible turbine pump, review the following checklist.



Be sure the well is clear of sand and abrasive material before installing pump. Abrasive materials in the water cause component wear and reduce pump capacity and discharge pressure. Never use the pump to develop or clean the well. Permanent pump damage can result within the first few hours of operation.



If the well casing is suspected of being crooked, check it with a gauge of identical length and diameter as the pump and motor with two lengths of pipe attached. Serious dam age can result if the pump becomes lodged in a crooked casing.



Be sure the well can supply a high-capacity turbine pump. The well should be deep enough to cover the pump unit with water, even at extreme pumping rates. Typically, the pump should be submerged 10 to 20 feet below the lowest water level and at least 5 feet above the bottom of the well.



Air entrained in the water reduces performance and will dam age the pump.



Your pump is designed to provide maximum efficiency under specific capacity and head conditions. Do not oper ate it beyond specified limits.



System controls and pump must match. Do not inter change controls with other models. Serious damage can result to the unit if pump and controls do not match.



Average number of starts per day will influence motor and control component life (starters, relays, capacitors, etc). Select pump size, tank size and control components for low est practical number of starts per day. Excessive cycling accelerates bearing, spline, and pump wear and con trol contact erosion.

PREINSTALLATION PROCEDURES AND CHECKS

ELECTRICAL SPLICES AND CONNECTIONS

Splices must be waterproof. Make a strong mechanical bond between the motor leads and the cable to avoid high resistance at the connection. A poor mechanical con nection, or a poorly wrapped splice, can cause motor problems and motor failure.

Before connecting the motor to the cable, perform a ground check to assure that the motor has not been damaged. Attach one end of an ohmmeter lead to any of the three motor leads and the other ohmmeter lead to the pump intake bracket. A new motor must have a resistance of 2 megohms or greater. If not, contact your dealer. Repeat for all three leads.

Prepare the cable and make the mechanical connections (Figure 1A) and splices as follows:

1. Cut motor leads and corresponding cable ends at 3-inch spacings to stagger connections for a smooth splice.

2. Cut connecting cable to match the motor leads. NOTICE: Match color coded wires, red to red, black to black, and white to white.

3. When using a butt connector, expose bare wire for about 1/2”. When using stranded wire, expose about 1” of wire.

NOTICE: Butt connectors may be used with solid wires through 8 AWG, or stranded wires through 10 AWG.

4. Clean exposed ends of wire thoroughly with emery cloth or sandpaper to assure good electrical connections.

5A. BUTT CONNECTORS (Figure 1A): Insert wires into con nector until insulation butts up against connector. Crimp connector to wires with a pair of crimping pliers. Pull on cable to make sure the connection is solid and tight.

5B. SOLDERED CONNECTIONS (Figure 1A):

NOTICE: Do not use acid core solder or corrosive solder paste.

6. Repeat Step 5 for each lead.

Figure 1A: C able Splic ing: Solid Wire, Stranded Wire

7. Taping splice (Figure 1B):

CAUTION

never use friction tape on a water-tight splice. Use Scotch Number 33, or equivalent.

7A. Clean joints and adjoining cable/wire insulation of all grease and dirt, and build up joint area with tape until it matches diameter of cable.

7B. Starting 1-1/2” back from the joint, firmly apply one layer of tape, overlapping about half the previous lap and continuing approximately 1-1/2” beyond joint. Cut tape evenly and press both ends firmly against cable.

Because friction tape is not water resistant,

I. Straighten individual cable strands and spread apart slightly.

II. Clean each strand and push strands of cable into matching (color-coded) open strands of the motor leads.

III. Wrap entire length of joint with fine copper wire until strands are compressed.

IV. Apply heat and solder. Solder will follow the heat; make sure solder flows throughout the joint. Pull firmly on cable to test joint.

7C. Apply two additional layers of tape, as described in Step 7B, beginning and ending 1-1/2” beyond the previous starting/ ending points.
