be used.

See nameplate for weight of base unit.

Take note of the entire weight of the unit. The hoist and chain must be adequately dimensioned for

the total weight of the unit (including lifting chains or steel ropes, and all accessories which may be

attached) and must comply with the current valid safety regulations.

All relevant safety regulators as well as general good technical practice must be complied with.

4 Electrical connection

Befor

e commissioning, an expert should check that one of the necessary electrical protective devices is

available. Earthing, neutral, earth leakage circuit breakers, etc. must comply with the regulations of the

localelectricitysupplyauthorityandaqualiedpersonshouldcheckthattheseareinperfectorder.

ATTENTION The power supply system on site must comply with VDE or other local regulations

with regard to cross-sectional area and maximum voltage drop. The voltage stated on

the nameplate of the pump must correspond to that of the mains.

ATTENTION Explosion-proof pumps may only be used in explosive zones with the thermal

sensors tted (leads: FO, F1).

The power supply cable must be protected by an adequately dimensioned slow-blow fuse corresponding to the

rated power of the pump.

The incoming power supply as well as the connection of the pump itself to the terminals on the control

panel must comply with the circuit diagram of the control panel as well as the motor connection

diagramsandmustbecarriedoutbyaqualiedperson.

All relevant safety regulators as well as general good technical practice must be complied with.

Please consult your electrician.

4.1 Seal monitoring

The pumps are supplied as standard with a DI probe for seal monitoring. The lighting up of the inspection

controlindicatorinthecontrolpanelbytheDIelectrodettedinthepumpmeansthatthereiswaterinthedry

chamber.

ATTENTION If the DI seal monitor is activated the unit must be immediately taken out of service.

Please contact your Sulzer Service Centre.

4.2 Temperature monitoring (PTC thermistor)

Thermal sensors protect the motor from overheating.

Thermal protection is in accordance with DIN 44082. PTC relays for use in control panels must also be in

accordance with this standard.

4.3 Bearing temperature monitor (optional)

PTC thermistor bearing monitor versions of AFC pumps include thermal protection in accordance with DIN

44082. PTC relays for use in control panels must also be in accordance with this standard.

NOTE! Running the pump with the thermal and/or moisture sensors disconnected will invalidate

related warranty claims.

5 Mounting and installation

The regulations covering the use of pumps in sewage applications, together with all regulations

involving the use of explosion-proof motors, should be observed.The cable ducting to the control

panelshouldbesealedo󰀨inagas-tightmannerbytheuseofafoamingmaterialafterthecable

and control circuits have been pulled through. In particular the safety regulations covering work in

enclosed areas in sewage plants should be observed together with general good technical practice.

5.2 Discharge line

The discharge line must be installed in compliance with the relevant regulations.

DIN 1986/100 and EN 12056 applies in particular to the following:

- Thedischargelineshouldbettedwithabackwashloop(180°bend)locatedabovethebackwashleveland

shouldthenowbygravityintothecollectionlineorsewer.

- The discharge line should not be connected to a down pipe.

- Nootherinowsordischargelinesshouldbeconnectedtothisdischargeline.

ATTENTION The discharge line should be installed so that it is not aected by frost.

5.3 Checking direction of rotation

Whenthreephaseunitsarebeingcommissionedforthersttimeandalsowhenusedonanewsite,the

directionofrotationmustbecarefullycheckedbyaqualiedperson.

When checking the direction of rotation, the pump should be secured in such a manner that no

dangertopersonneliscausedbytherotatingimpeller,orbytheresultingairow.Donotplaceyour

hand into the hydraulic system!

The direction of rotationshouldonlybealteredbyaqualiedperson.

When carrying out the direction of rotation check as well as when starting the unit pay attention to the

START REACTION. This can be very powerful.

ATTENTION

The direction of rotation is

correct if the impeller rotates in a

clockwise manner when viewing

down from the motor end of the

placed unit.

1019-00

ATTENTION

The start reaction is

anti-clockwise.

Rotor rotation

NOTE If a number of pumps are connected to a single control panel then each unit must be

individually checked.

ATTENTION The mains supply to the control panel should have a clockwise rotation. If the leads

are connected in accordance with the circuit diagram and lead designations, the

direction of rotation will be correct.

5.4 Changing direction of rotation

The direction of rotationshouldonlybealteredbyaqualiedperson.

If the direction of rotation is incorrect then this is altered by changing over two phases of the power supply cable

in the control panel. The direction of rotation should then be rechecked.

Commissioning

Before commissioning, the pump should be checked and a functional test carried out. Particular attention

should be paid to the following:

- Have the electrical connections been carried out in accordance with regulations?

- Have the thermal sensors been connected?

- Is the seal monitoring device correctly installed?

- Is the motor overload switch correctly set?

- Is the direction of rotation of the pump correct - even if run via an emergency generator?

- Are the level control switches functioning correctly?

- Aretherequiredgatevalves(wheretted)open?

- Dothenon-returnvalves(wheretted)functioneasily?

6.1 Types of operation and frequency of starting

All pumps of the AFC series have been designed for continuous operation S1.

ATTENTION Explosion-proof pumps may only be used in explosive zones with the thermal

sensors tted (leads: FO, F1).

7 Maintenance

Before commencing any maintenance work the pump should be completely disconnected from the

mainsbyaqualiedpersonandcareshouldbetakenthatitcannotbeinadvertentlyswitchedback

on.

When carrying out any repair or maintenance work, the safety regulations covering work in enclosed

areas of sewage installations as well as good general technical pratices should be followed.
