SAFETY WARNING

Electrical Work

WARNING: Reduced risk of electric shock during operation of this pump requires the provision of acceptable grounding. If the means of connection to the supply connected box is other than grounded metal conduit, ground the pump back to the service by connecting a copper conductor (at least the size of the circuit supplying the pump) to the grounding screw provided within the wiring compartment.

Pre-Installation Checklist

1. Well Preparation

If the pump is to be installed in a new well then the well should be fully developed and bailed or blown free of cuttings and sand. The construction of the GRUNDFOS

SQ/SQE submersibles makes it resistant to abrasion; however, no pump made of any material can forever withstand the destructive wear that occurs when constantly pumping sandy water.

If this pump is used to replace an oil-filled submersible or oil-lubricated line-shaft turbine in an existing well, the well must be blown or bailed clear of oil.

2. Make Sure You Have the Right Pump

Determine the maximum depth of the well, and the drawdown level at the pump's maximum capacity. Pump selection and setting depth should be made based on this data.

3. Pumped Fluid Requirements

Submersible well pumps are designed for pumping clear, cold water; free of air or gases. Decreased pump performance and life expectancy can occur if the water is not clear, cold or contains air or gases. Water temperature should not exceed 104°F.

A check should be made to ensure that the installation depth of the pump will always be at least three feet below the maximum drawdown level of the well. The bottom of the motor should never be installed lower than the top the screen or within five feet of the well bottom, as shown in fig.1.

I.D.

4. Motor Cooling Requirements

Fig. 1

To ensure proper motor cooling refer to the table below for minimum flow requirements:

Flow velocity past the motor

Maximum liquid temperature

0.0 f/s

(free convection)

86° F(30°C)

Min. 0.5 f/s 104°F (40°C)

Page 1

Pre-Installation Checklist

If the pump is to be installed horizontally, e.g. in a tank, and there is a risk that the pump might be covered by mud, it must be installed in a flow sleeve.

Liquid temperatures/cooling

Figure 2 illustrates the following:

- Well diameter.

- Pump diameter.

- Temperature of pumped liquid.

- Flow past the motor to the pump

suction strainer.

Note: The well diameter must be at least 3”. If there is a risk that the motor will be covered with sediment then it is recommended the pump be placed in a Flow Sleeve. The motor should always be installed above the well screen.

5. Applications

Typical applications:

Groundwater supply for

- residential housing.

- small waterworks.

Fig. 2

- irrigation systems.

- liquid transfer in tanks.

Note: The pump must not be used as a booster pump in a booster system.

6. Motor Preparation

GRUNDFOS MS 3 and MSE 3 submersible motors have water-lubricated slide bearings. No additional lubrication is required.

The submersible motors are factory-filled with a special GRUNDFOS motor liquid (type SML 2), which will protect the motor fluid down to

-4°F(20°C) and to prevent the growth of bacteria. The level of motor fluid is important for the operating life of the bearings and consequently the life of the motor.

Refilling of motor liquid

It is recommended to refill the motor with GRUNDFOS motor fluid SML 2.

Pre-Installation Checklist

To refill the motor, proceed as follows:

1. Remove the cable guard and separate the pump end from the motor.

2. Place the motor in vertical position with an inclination of approx. 10°.

3. Remove the filling plug using a screwdriver or a similar tool.

4. Inject motor liquid into the motor with a filling syringe or similar tool,see fig. 3.

5. To allow possible air to escape, move the motor from side to side. And turn the shaft.

Fig. 3

6. Replace the filling plug and make sure it is tight.

7. Assemble pump end and motor.

8. Install the cable guard.

Installation Procedures

8. Electrical connection

General

The electrical connection should be carried out by an authorized electrician in accordance with local regulations.

Before starting work on the pump, make sure the electricity supply has been switched off and that it cannot be accidentally switched on. The pump must be grounded. The pump must be connected to an external mains switch.

The supply voltage, rated maximum current and power factor (PF) appear on the motor nameplate.

The required voltage for GRUNDFOS submersible MS3/MSE3 motors, measured at the motor terminals, is +6%/–10% of the nominal voltage during continuous operation (including variation in the supply voltage and losses in cables).

If the pump is connected to an installation where a Ground Fault circuit breaker (GFI) is used as additional protection, this circuit breaker must trip out when ground fault currents with DC content (pulsating DC) occur.

Supply voltage:1 x 100-115V or 1 x 200-240 V +6%/–10%, 50/60 Hz.

The current consumption can only accurately be measured by means of a true RMS instrument. If other instruments are used, the value measured will differ from the actual value.

The SQE pumps can be connected to a CU 300 status box.

Note: The pump must never be connected to a capacitor or to another type of control box other than a CU 300.

The pump must never be connected to an external frequency converter.

Motor protection

The motor has built-in automatic thermal overload protection and requires no additional motor protection.

Connection of motor

The motor can be connected directly to the main circuit breaker.

Start/stop of the pump will typically be done via a pressure switch, see fig. 5.

Note: The pressure switch must be rated for the maximum amps of the specific pump size.

11. Splicing the Cable

Splice the drop cable with the motor cable. If the splice is carefully made, it will be as efficient as any other portion of the cable and will be completely watertight.

There are a number of cable splicing kits available today - epoxy filled, rubber-sealed, etc. Many perform well if the manufacturer's directions are followed carefully. If one of these kits is not used, we recommend the following method for splicing the motor cable to the drop cable:

Examine the motor cable and the drop cable carefully for damage.

Cut the motor leads off in a staggered manner. Cut the ends of the drop cable so that the ends match up with the motor leads. Be sure to match the colors.

Strip back and strip off one-inch of insulation from each lead, making sure to scrape the wire bare to obtain a good connection. Be careful not to damage the copper conductor when stripping off the insulation.

Insert a properly sized Sta-Kon-type connector on each pair of leads, again making sure that colors are matched. Using Sta-Kon crimping pliers, indent the lugs. Be sure to squeeze down hard on the pliers, particularly when using large cable.

Form a piece of electrical putty tightly around each Sta-Kon. The putty should overlap on the insulation of the wire.

Use a good quality tape such as #33 Scotch Waterproof or Plymouth

Rubber Company Slipknot Grey.

Wrap each wire and joint tightly for a distance of about 2½ inches on each side of the joint.

Make a minimum of four passes over each joint and overlap each pass approximately one inch to assure a completely watertight seal.

14. Piping

• The pump should only be gripped by the two flats at the top of the pump, as shown in fig. 9.

• The pump can be installed vertically or horizontally. During operation, the pump must always be completely submerged in water.

• When plastic pipe is used, a stainless steel safety wire is recommended for lowering and lifting the pump. Fasten the wire to the eyelet on the pump, as shown in fig. 10.

• The threaded joints must be well cut and fit together tightly to ensure that they do not work loose.

15. Installing the Pump

Installation Depth

The dynamic water level should always be above the pump see fig. 11.

A = Dynamic water level

B = Static Water Level

C = Minimum 3" well diameter

D = Drawdown

E = Installation depth below static water level. Maximum 500 feet

Procedures

To install the pump, follow these steps:

1. Install the enclosed data plate sticker at the well head.

2. Check the well for proper clearance — the well must be at least 3" in diameter. It is a good idea to check the well for clearance using a plumb ring (2.95 ø x 10 in.).

3. Attach the first section of riser pipe to the pump.

Installation Procedures

16. Installing the Pump(cont.)

4.

Lower the pump into the well. Make sure the motor cable is not damaged when the pump is lifted or lowered into the well — especially in 3" wells.

NOTE: Do not lower or lift the pump using the motor cable.

5.

When the pump has been installed to the required depth, the installation should be finished by means of a well seal. Note that the dynamic water level should always be above the pump.

6.

Loosen the safety wire so that it becomes unloaded and lock it to the well seal using a cable clamp.

7.

Attach the supplemental information label at the electrical installation site.

8.

Complete the electrical connections. Remember that a capacitor or a control box should NEVER be connected to a

SQ/SQE submersible pump.

Installation depths

Maximum installation depth: below the static water level: 500 feet,

Minimum installation depths: 1.75' below the dynamic water level:

Vertical installation:

During start-up and operation, the pump must always be completely submerged in water.

Horizontal installation:

The pump must be installed at least 1.75 ft. below the dynamic water level. If there is a risk that the pump might be covered by mud, the pump must always be placed in a flow sleeve.

Note: Do not lower or lift the pump with the motor cable.

17. Generator Operation

• It is OK to operate the SQ/SQE with a generator.

The generator must be sized 10% above the pumps P1 (Input

Power) values.

Operating the Pump

18. Starting the Pump for the First Time

When the pump has been connected correctly, the pump should be started with the discharge valve closed approximately one-third. Due to the soft start feature, the pump takes approximately 2 seconds to develop full pressure.

Motor Cooling and Other Considerations

• Make sure the well is capable of yielding a minimum quantity of water corresponding to the pump capacity.

• Do not start the pump until it is completely submerged in the liquid.

• As the valve is being opened, the drawdown should be checked to ensure that the pump always remains submerged.

• To ensure the necessary cooling of the motor, the pump should never be set so low that it gives no water. If the flow rate suddenly falls, the reason might be that the pump is pumping more water than the well can yield. The pump must immediately be stopped and the fault remedied.

Water Impurities

• If there are impurities in the water, the valve should be opened gradually as the water becomes clearer. The pump should not be stopped until the water is clean, otherwise the pump parts and the check valve may become clogged.

• When the water is clean the valve should be fully opened.

Minimum flow rate

• To ensure the necessary cooling of the motor, the pump flow rate should never be set to a value lower than .2 gpm. If the flow rate suddenly falls, the reason might be that the pump is pumping more water than the well can yield. The pump must be stopped and the fault corrected.

Note: The pump's dry-running protection is effective only within the recommended duty range of the pump.

Note: Do not let the pump run against a closed discharge valve for more than 5 minutes. When the discharge valve is closed, there is no cooling flow and there is a risk of overheating in motor and pump.

Operating the Pump

Built-in protection

The motor incorporates an electronic unit which protects the motor in various situations.

In case of overload, the built-in overload protection will stop the pump for

5 minutes. After that period, the pump will attempt to restart.

If the pump is started and the well has not recovered, the pump will stop after 30 seconds.

If the pump has been stopped as a result of dry running, it will start automatically after 5 minutes.

Resetting the pump:

Switch off the electricity supply for 1 minute.

The motor is protected against the following conditions:

- dry running,

- voltage surges (up to 5000 V),

- overvoltage,

- undervoltage,

- overload

- overtemperature.

MS 3 Motors:

Note: All MS 3 motors are factory set to detect dry running conditions.

However, it is important to ensure that the configurations of both the SQ pump and motor are the same configuration. Configurations can be found on both SQ pump and motor nameplates as “ Config.”

EXAMPLE: Config. A-2, must match the other nameplate A-2. See

Technical Data on page 17 for quick referencing on all configurations.

MSE 3 Motors:

Note: To set Dry-Run limit in the MSE/SQE pumps, you need to connect the pump to a CU 300. Refer to CU 300 I&O for proper connections.

To set Dry-Run protection, follow these steps:

1. Start the pump against closed discharge.

2. Rapidly read the power consumption value (W) in the R100

display 2.5.

3. Multiply this value by 0.9.

4. Within the R100, go to display 4.6 and enter the new value

(minimum power limit).

5. Go to display 4.7 and change the setting to “Active”.

For further information on dry-running, refer to CU 300 I&O.

Maintenance and service:

The pumps are normally maintenance-free.

Deposits and wear may occur. For that purpose, service kits and service tools are available from GRUNDFOS. The GRUNDFOS Service Manual is available on request.

The pumps can be serviced at a GRUNDFOS service center.
