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

This is the safety-alert. 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.

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.

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

To avoid serious or fatal personal injury and possible property damage, carefully read and follow the safety instructions.

Hazardous pressure. Under certain conditions, submersible pumps can develop extremely high pressure. Install a pressure relief valve capable of passing entire pump flow at 75 PSI (517 kPa) when using an air over water pressure tank. Install a pressure relief valve capable of passing entire pump flow at 100 PSI (690 kPa) when using a pre-charged pressure tank.

Do not allow pump, pressure tank, pip-

ing, or any other system component containing water to freeze. Freezing may damage system, leading to injury or flooding. Allowing pump or system components to freeze will void warranty.

2. Hazardous voltage. Can shock, burn or cause death. To avoid dangerous or fatal electric shock hazard, use pump only in a water well.

Risk of dangerous or fatal electrical

shock. Do not install this pump in any pond,

river, or other open body of water that could be used for swimming or recreation. Do not swim, wade or play in a body of water in which a submersible pump has been installed.

Installation must meet United States

National Electrical Code, Canadian Electrical Code, and local codes (as applicable) for all wiring.

Disconnect electrical power supply before

installing or servicing pump.

Make sure line voltage and frequency of

power supply match motor nameplate voltage and frequency.

3. Install pump according to all plumbing, pump and well code requirements.

4. Test well water for purity before using well. Call

your local health department for testing procedure.

5. During installation, keep well covered as much as possible to prevent leaves and foreign matter from falling into well. Foreign objects in well can contaminate the water and cause serious mechanical damage to the pump.

6. Pipe joint compound can cause cracking in plastics. Use only teflon tape when sealing joints in plastic pipe or connecting pipe to thermoplastic pumps.

PRE-INSTALLATION

Inspect pump and motor for delivery damage. Report any damage immediately to the shipping carrier or to your dealer.

The well driller should thoroughly develop the well (that is, pump out all fine sand and foreign matter) before pump is installed.

Pump performance is based on pumping clear, cold, liquid water.

Warranty is void in the following conditions:

• If pump has pumped excessive sand – excessive sand can cause premature wear to pump.

• If water is corrosive.

• If entrained gas or air are present in the water being pumped – these can reduce flow and cause cavitation which can damage pump.

• If pump has been operated with discharge valve closed – severe internal damage will result.

Install pump at least 15 to 20' (4.5 to 6M) below the lowest water level reached with pump running (lowest draw-down water level), and at least 5' (1.5M) above the bottom of the well.

WIRING/GROUNDING:

Hazardous voltage. Can shock, burn, or cause death. Permanently ground pump, motor and control box before connecting power supply to motor.

Ground pump and motor in accordance with the local codes and ordinances. Use a copper ground wire at least as large as wires carrying current to motor.

Motor is supplied with a copper ground wire. Splice this ground wire to a copper conductor that matches motor wire size specified in cable sizing charts,pages 5, 6, 10, and 11. See Pages 19 and 20 for cable splicing instructions.

Permanently ground pump, motor and control box before connecting power cable to power supply. Connect ground wire to approved ground first and then connect to equipment being installed.

Do not ground to a gas supply line.

Fire and electrical shock hazard. If using a drop cable larger than No. 10 (5.5mm2) (for example, No. 8 (8.4mm2) wire) between pump and control box, run cable to a separate junction box. Connect junction box to control box with a No. 10 (5.5mm2) or smaller wire (depending on amp rating of pump – see Table II, III, or IV).

For more information, contact your local code officials.

WIRING CONNECTIONS:

Installation must meet United States National Electrical Code, Canadian Electrical Code and local codes for all wiring (as applicable).

Use only copper wire when making connections to pump and control box.

To avoid over-heating wire and excessive voltage drop at motor, be sure that wire size is at least as large as size listed in cable sizing charts for your horsepower pump and length of wire run.

NOTICE: See Pages 14 through 18 for typical wiring hookups and control box identification.

NOTICE: When built-in overheating protection is not provided, install an approved overload

equipped motor control that matches motor input in full load amps. Select or adjust overload element(s) in accordance with control instructions. When built-in overheating protection is provided, use an approved motor control that matches motor input in full load amperes.

Rotation – (3 Phase only)

To make sure motor is running in the right direction, proceed carefully as follows:

After electrical connections have been made as outlined, and with pump hanging in well supported from clamp on the discharge pipe, turn on then turn off the switch connecting the motor to the power supply line. Note rotation of pump as motor starts. If connections are properly made, pump will “jerk” clockwise when looking into the pump discharge when started. If “jerk” is counter-clockwise, the motor is running in the

wrong direction. Interchange any two cable leads where they connect to the “lead” terminals in the magnetic starter. With connections properly made, and pump lowered into water, turn on the switch again and the pump should deliver water according to the performance charts.

OVERLOAD PROTECTION OF THREE PHASE SUBMERSIBLE MOTORS – CLASS 10 PROTECTION REQUIRED

The characteristics of submersible motors are different from standard motors and special overload protection is required.

If the motor is stalled, the overload must trip within 10 seconds to protect the motor windings. The installer must use SUBTROL or the quick-trip protection shown in Tables VIII and IX. All recommended overload selections are of the ambient compensated type to maintain protection at high and low air temperatures.

All heaters and amp settings shown are based on total line amps. When a six-lead motor is used with a Wye-Delta starter, divide motor amps by

1.732 to make your selection or adjustment for heaters carrying phase amps.

Table VIII lists the correct selection and settings of overloads for PENTEK T-Series motors. Table IX lists the same for Franklin motors. Approval of other types may be requested from the motor manufacturer.

NOTICE: Warranty on three phase submersible motors is void unless proper quick trip protection in all three motor lines is used.

SURGE ARRESTERS IN CONTROL BOX

Grounding: When the box has a surge arrester, the surge arrester MUST be grounded, metal to metal, all the way to the water strata for the arrester to be effective. Grounding the arrester to a driven ground rod provides little or no protection for the motor.

NOTICE: Surge arresters DO NOT protect

against direct lightning strikes. Install grounded surge arresters to protect pump

from high voltage surges. Install arrester on the incoming power line to control box or pressure switch, as close to pump motor as possible. See Figures 1 and 2 for installation wiring diagrams for arresters.

NOTICE: Ground the arrester with a No. 10 or larger bare wire. Ground according to local code requirements.

NOTICE: If surge arresters wired into the control box are against local electrical code, contact power company for correct wiring information.

PENTEK T-Series 3-Phase 4" MOTOR OVERLOAD PROTECTION

PENTEK T-Series 3-phase submersible motors must have Class 10 overload protection that will disconnect the power within 10 seconds in the case of a locked rotor. To accomplish this, fixedheater overloads are used. Refer to the chart below for appropriate heaters. The chart is based upon total line amps.

Divide the motor amps by 1.732 when using a 6lead motor with a Y-Delta Starter.

NOTICE: General Electric overload heaters are only usable with General Electric overload relays.

Do not adjust relays to exceed nameplate amps.

For reliable 3-Phase starter operation, length of wire between starter and service entrance should be not more than 25% of total wire length.

starter sizes apply where (1) is shown in tables, size 13/4 replacing 2, 2-1/2 replacing 3, 3-1/2 replacing 4 and 4-1/2 replacing 5. Heaters were selected from Catalog 294, Table 332 and Table 632 (starter size 00, size B). Size 4 starters are heater type 4 (JG). Starters using these heater tables include classes 14, 17 and 18 (INNOVA), classes 36 and 37 (reduced voltage), and classes 87, 88 and 89 (pump and motor control centers). Overload relay adjustments should be set no higher than 100% unless necessary to stop nuisance tripping with measured amps in all lines below nameplate maximum. Heater selections for class 16 starters (Magnetic Definite Purpose) will be furnished upon request.

NOTE 2: Allen-Bradley heaters were selected from Catalog IC-110, Table 162 (through starter size 4), Table 547 (starter size 5), and Table 196 (starter size 6). Bulletin 505, 509, 520, 540 and 570 use these heater tables. Heater selections for bulletin 1232X and 1233X starters will be furnished upon request.

NOTE 3: General Electric heaters are type CR123 usable only on type CR124 overload relays and were selected from Catalog GEP-126OJ, page 184. Adjustment should be set no higher than 100%, unless necessary to stop nuisance tripping with measured amps in all lines below nameplate maximum.

NOTE 4: Adjustable overload relay amp settings apply to approved types listed. Relay adjustment should be set at the specified SET amps. Only if tripping occurs with amps in all lines measured to be within nameplate maximum amps should the setting be increased, not to exceed the MAX value shown.
