Before beginning installation procedures,
these installation and operating instructions should be studied carefully. The installation and operation should also be inaccordance with local regulations and accepted codes of good practice.

The SQ/SQE is a 3 inch diameter submersible pumpmainly designed for the pumping of raw water in domestic water supply. This manual is designed to assist
in the proper set-up, installation and operation ofthese pumps.

1.1 Applications
Typical applications are:• residential housing• small waterworks• pressure boosting• irrigation systems• liquid transfer in tanks.

2. Preinstallation
2.1 Well preparation
If the pump is to be installed in a new well, the wellshould be fully developed and bailed or blown free of
cuttings and sand.
The construction of the Grundfos SQ/SQE submersibles makes them resistant to abrasion; however, nopump made of any material can forever withstand thedestructive 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.

2.2 Make sure you have the right pump
Determine the maximum depth of the well and thedrawdown level at the maximum pump capacity.
Pump selection and setting depth should be madebased on this data.

2.3 Pumped liquid 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.
The 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 threefeet below the maximum drawdown level of the well.
The bottom of the motor should never be installed
lower than the top of the well screen or within fivefeet of the well bottom.

2.4 Motor cooling requirements

2.6 Motor preparation

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

Grundfos MS 3 and MSE 3 submersible motors havewater-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 liquid down to 4°F (–20°C) and preventthe growth of bacteria. The level of motor liquid is important for the operating life of the bearings and consequently the life of the motor.

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

2.5 Liquid temperatures/cooling
Figure 1 shows an SQ/SQE pump installed in a well.
With the pump operating, figure 1 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 inches.
If there is a risk that the motor will be covered withsediment, it is recommended the pump be placed in aflow sleeve. The motor should always be installed
above the well screen.

2.7 Refilling of motor liquid
If for any reason the motor liquid has been drained orlost, the motor must be refilled with Grundfos motor
liquid SML 2.
To refill the motor, proceed as follows:
1. Remove the cable guard and separate the pumpend from the motor.
2. Place the motor in vertical position with an inclination of approximately 10°.
3. Remove the filling plug using a screwdriver or asimilar tool.
4. Inject motor liquid into the motor with a filling syringe or similar tool, see fig. 2.
5. To allow possible air to escape, move the motor
from side to side and turn the shaft.
6. Replace the filling plug and make sure it is tight.
7. Assemble pump end and motor.
8. Fit the cable guard.
The pump is now ready for installation.

3. Installation positions
3.1 Positional requirements
The pump is suitable for vertical as well as horizontal
installation, however, the pump shaft must never fall
below the horizontal plane, see fig. 3.
If the pump is to be installed horizontally, e.g. in atank, and there is a risk that the pump might be covered by mud, it must be installed in a flow sleeve.

Supply voltage:
1 x 90-120 V or 1 x 200-240 V –10%/+6%, 50/60 Hz.
The current consumption can only be measured accurately 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 or
CU 301 control box.

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

4.3 Connection of motor

Fig. 3 Pump position

4. Electrical connection
4.1 General
The electrical connection should be carried out by anauthorized electrician in accordance with local regulations.
Before starting work on the pump, makesure that the electricity supply has beenswitched 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 andpower factor (PF) appear on the motor nameplate.
The required voltage for Grundfos submersible
MS 3/MSE 3 motors, measured at the motor terminals, is –10%/+6% 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 whenground fault currents with DC content (pulsating DC)
occur.
Note: The pump must never be connected to a capacitor or to another type of control box than CU 300 or
CU 301.
Note: The pump must never be connected to an external frequency converter.

6

The motor can be connected directly to the main circuit breaker.
Start/stop of the pump will typically be done via apressure switch, see fig. 4.
Note: The pressure switch must be rated for the maximum amps of the specific pump.
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 isother than grounded metal conduit, groundthe pump back to the service by connecting
a copper conductor, at least the size of thecircuit supplying the pump.

7. Fitting the cable plug to the motor

Splice the drop cable with the motor cable. If the
splice is carefully made, it will be as efficient as anyother 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:
1. Examine the motor cable and the drop cable carefully for damage.
2. Cut the motor leads off in a staggered manner.
3. Cut the ends of the drop cable so that the ends
match up with the motor leads.
Be sure to match the colors.
4. Strip back and strip off one inch of insulation fromeach lead, making sure to scrape the wire bare toobtain a good connection.
Be careful not to damage the copper conductor
when stripping off the insulation.
5. 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.
6. Form a piece of electrical putty tightly aroundeach Sta-Kon™. The putty should overlap on theinsulation of the wire.
7. 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 ofabout 2½ inches on each side of the joint.
Make a minimum of four passes over each joint
and overlap each pass approximately one inch toensure a completely watertight seal.
Note: Do not lower or lift the pump using the motor
cable.

The cable plug supplied with the motor is factorygreased. Check that the plug is greased correctly,
see fig. 5.

TM02 9604 3504

6. Splicing the cable

Fig. 5 Greasing of plug

TM02 9605 3504

To fit the cable plug, proceed as follows:
1. Check that the cable is of the correct type, crosssection and length.
2. Check that the mains on the location has correctconnection to ground.
3. Check that the motor socket is clean and dry.
4. Press the cable plug onto the motor socket.
The plug will only fit one way, see fig. 6.
5. Fit and tighten the four screws, see fig. 6.
When the plug has been fitted, there must not bea clearance between the motor and the cable plug.

Fig. 6 Fitting the cable plug7• The pump should only be gripped by the two flatsat the top of the pump, see 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 thepump. Fasten the wire to the eyelet on the pump,see fig. 10.
• The threaded joints must be well cut and fit together tightly to ensure that they do not workloose.

Fig. 10 Installation depth
Procedure:
To install the pump, proceed as follows:
1. Attach the enclosed data plate sticker at the wellhead.
2. Check the well for proper clearance. The well mustbe at least 3 inches in diameter. It is a good idea tocheck 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.
4. Lower the pump into the well. Make sure the motor cable is not damaged when the pump is liftedor lowered into the well, especially in 3 inch wells.
Note: Do not lower or lift the pump using the motor cable.

It is safe to operate the SQ/SQE with a generator.
The generator must be sized 50% above the P1 (input
power) values of the pump. See the following table.

12. Starting the pump for the first time

12.5 Resetting the pump

When the pump has been connected correctly, thepump 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.

Switch off the electricity supply for 1 minute.
The motor is protected against the following conditions:• dry running• voltage surges (up to 6000 V)
In areas with high lightning intensity, external
lightning protection is required.
• overvoltage• undervoltage• overload• overtemperature.

12.1 Motor cooling and other considerations• Make sure the well is capable of yielding a minimum quantity of water corresponding to the pumpcapacity.
• 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, thepump should never be set so low that it gives nowater.
If the flow rate suddenly falls, the reason might bethat the pump is pumping more water than thewell can yield. The pump must immediately be
stopped and the fault corrected.

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

12.3 Minimum flow rate
To ensure the necessary cooling of the motor, thepump flow rate should never be set to a value lower
than 0.2 gpm.
If the flow rate suddenly falls, the reason might bethat the pump is pumping more water than the well
can yield. The pump must immediately be stopped
and the fault corrected.
Note: The pump’s dry-running protection is effective
only within the recommended duty range of thepump.
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 andthere is a risk of overheating in motor and pump.

12.4 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 has been stopped as a result of dry running, it will start automatically after 5 minutes.
• If the pump is restarted and the well has not recovered, the pump will stop after 30 seconds.

10

12.6 MS 3 motors
Note: All MS 3 motors are factory-set to detect dryrunning conditions.
Check that the combination of pump and motor corresponds to the data on page 39.

12.7 MSE 3 motors
Note: All MSE 3 motors are factory-set to detect dryrunning conditions. However, if the maximum pumpspeed setting is changed, the dry running stop value
must also be changed. Please refer to either the
CU 301 or CU 300 I&O for instructions on this procedure.

12.8 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.

13. Assembly of pump and motor
