Grundfos’ factory or authorized service station, any product of Grundfos manufacture. Grundfos will not be liable for any costs of removal, installation, transportation, or any other charges that may arise in connection with a warranty claim.

Products which are sold, but not manufactured by Grundfos, are subject to the warranty provided by the manufacturer of said products and not by Grundfos' warranty.

Grundfos will not be liable for damage or wear to products caused by abnormal operating conditions, accident, abuse, misuse, unauthorized alteration or repair, or if the product was not installed in accordance with Grundfos' printed installation and operating instructions and accepted codes of good practice. The warranty does not cover normal wear and tear.

To obtain service under this warranty, the defective product must be returned to the distributor or dealer of Grundfos' products from which it was purchased together with proof of purchase and installation date, failure date and supporting installation data. Unless otherwise provided, the distributor or dealer will contact Grundfos or an authorized service station for instructions. Any defective product to be returned to Grundfos or a service station must be sent freight prepaid; documentation supporting the warranty claim and/or a Return Material Authorization must be included if so instructed.

6.1 Mechanical installation

6.1.1 Pump position

Fig. 2 Correct mounting position

The pump is designed for tank mounting in the vertical position. The pump is positioned in a hole cut into the cover of the tank (upper side) and secured to the tank by hexagon head screws through the holes in the mounting flange. We recommend to fit a sealing gasket between pump flange and tank.

For ventilation and cooling, leave a clearance of minimum 2" (50 mm) above the motor.

The pump is designed for indoor operation only. Do not spray liquids directly on the motor.

6.1.2 Terminal box positions

The terminal box of most of the MTA pump types can be turned to another position after delivery. See the table below.

● The terminal box can be turned to another position after delivery.

( ● ) The terminal box cannot be turned to

another position after delivery.

Fig. 3 Possible terminal box positions

(top view)

To turn the terminal box to another position, do as follows:

1. Remove the bolts securing the motor to the pump.

2. Turn the motor to the required position.

3. Refit and tighten the bolts securing the motor to the pump.

Connect the electric motor to the power supply as shown in the diagram in the terminal box cover.

6.2 Electrical installation

6.2.1 Electrical connection

Carry out the electrical connection according to local regulations.

Check that the supply voltage and frequency correspond to the values stated on the nameplate.

The operating voltage and frequency are marked on the pump nameplate. Make sure that the motor is suitable for the power supply available.

The motor must be connected to a motor-protective circuit breaker.

We do not recommend operation via frequency converter.

7. Operation

7.1 Start-up

The pump can be started against an open or a closed discharge valve.

Before starting the pump:

• Make sure that all pipe connections are tight.

• Make sure that the pump is immersed to the recommended level.

• Make sure that chip trays are not blocked by impurities.

Start the pump as follows:

1. See the correct direction of rotation of the pump on the motor fan cover or on the sight glass. When seen from the top, the pump should rotate counter-clockwise.

2. Start the pump and check the direction of rotation.

the correct direction of rotation

Fig. 5 Sight glass with indication of the

correct direction of rotation

8. Maintenance and service

8.1 Maintenance

Pumps installed in accordance with these instructions require very little maintenance.

8.1.1 Lubrication

The motor ball bearings are grease-packed and sealed for life. No further lubrication is necessary.

8.1.2 Filters

Chip trays, filters, etc. should be cleaned at regular intervals to ensure a correct flow of liquid. This will also increase the pump l ife.

8.1.3 Periodic checks

Make the following checks at regular intervals, depending on the conditions and time of operation.

• Check the quantity of liquid and operating pressure.

• Check that there are no leaks.

• Check that the motor is not overheating.

• Check the tripping of the motor-protective circuit breaker.

• Check that all control devices are operating satisfactorily.

If the above checks do not reveal any abnormal operating details, no further checks are necessary.

Should any faults be found, see section 9. Fault finding.

8.2 Service

8.2.1 Contaminated pumps

Before the pump is returned to Grundfos for service, the certificate of cleanliness must be filled in and sent to Grundfos. See page 10. If Grundfos is requested to service the pump, it must be cleaned before it is returned.

If the above is not fulfilled, Grundfos can refuse to accept the pump for service. Possible costs of returning the pump are to be paid by the customer.

TM04 8004 2610TM04 8003 2610

Warning If used for a liquid which is

injurious to health or toxic, the pump will be classified as contaminated.

English (US)

9. Fault finding

Warning Before starting fault finding, switch off the power supply.

Make sure that the power supply cannot be accidentally switched on.

Fault Cause Remedy

1. Motor does not run when power supply is switched on.

a) Supply failure. Connect the power supply. b) Fuses are blown. Replace the fuses. c) Motor-protective circuit breaker

has tripped.

Reactivate the motor protection.

d) Main contacts in motor-protective

circuit breaker are not making contact or the coil is faulty.

Replace the contacts or the magnetic coil.

e) Control circuit is defective. Repair the control circuit. f) Motor is defective. Replace the pump.

2. Motor-protective circuit breaker trips immediately when power supply is switched on.

a) Fuse on one phase is blown. Replace the fuse. b) Contacts in motor-protective

circuit breaker are faulty.

Replace the contacts in the motor-protective circuit breaker.

c) Cable connection is loose or

faulty.

Fasten or replace the cable

connection. d) Motor winding is defective. Replace the pump. e) Pump mechanically blocked. Remove the mechanical blocking of

the pump. f) Overload setting is too low. Set the motor-protective circuit

breaker correctly.

3. Motor-protective circuit breaker trips occasionally.

a) Overload setting is too low. Set the motor-protective circuit

breaker correctly.

b) Low voltage at peak times. Check the power supply.

4. Motor-protective circuit breaker has not tripped, but the pump does not run.

a) Check 1 a), b), d) and e).

5. Pump runs, but gives no liquid, or pump capacity is not constant.

a) Pump inlet partly blocked by

impurities.

Clean the inlet.

b) Liquid level in tank is too low. Increase the liquid level. c) Pump rotates in the wrong

direction.

Change the direction of rotation of the motor by switching any two of the phases.
