5.2  Orientation of terminal box (see FIG. 3)

If  necessary,  the  orientation  of  the  motor,  and  with  it

that of the terminal box, can be changed.

-

Remove  the  motor  attachment  screws  and  turn  the

motor to the desired position.

Take  care  not  to  damage  the  casing

gasket, and reinstall it correctly.

The  terminal  box  should  not  be  placed

at  3  and  6  o’clock  on  an  ice  water

circuit.

5.3  Electrical connection

The  electrical  connection  must  be  made  by  a

qualified  electrician  and  comply  with

applicable local standards.

Complete electrical information about the circulator is

given on the data plate.

Power supply network

Use a three-conductor cable (3 x 1,5 mm2 H05 VVF) to

connect  mains  power  to  the  corresponding  terminals

of the circulator:  phase (L), neutral (N), and earth (   )

(

see FIG. 4

).

The power cable must not touch the pipe or the

pump;  make  sure  that  it  is  away  from  any

moisture.

Check  line  protection  and  the  mains  voltage  and

frequency.

The  circulator  must  be  connected  to  the  mains  via  a

switch  with  an  opening  distance,  on  each  pole,  of  at

least 3 mm.

The power outlet must have an earthing contact.

After  making  the  connections,  put  the  cover  back  on

the terminal box.

6.  STARTING UP

6.1  Filling, degassing

Never  operate  the  circulator  WITHOUT

WATER.

- Open the valves on both sides of the circulator and

fill the installation completely.

- Bleed the circuit at the high point.

- Power up the motor to start the circulator.

- The  running  ranges  are  adjusted  by  changing  the

position of the selector switch (

see FIG. 5

).

Risk  of  burning.    In  operation,  the  motor  casing

may be hotter than 100°C.

7.  SERVICING

The circulator needs no special servicing in operation.

The  motor  bushings  are  lubricated  by  the  liquid

pumped.

At  the  beginning  of  each  heating  season,  or  after  a

prolonged  shutdown,  make  sure  that  the  circulator

turns freely.

INCIDENT

8.1THE CIRCULATOR

IS NOISY

8.2THE CIRCULATOR

FAILS TO START

CAUSE

a) Air in circulator:

b) The  suction  pressure  is  too

low:

c) Considerable 

flowing

water noise:

d) Foreign bodies in impeller: 

a) No  power  supply  to

circulator:

b) Foreign bodies in impeller: 

REMEDIES

a) Put the selector switch in position 1.

b) Raise the pressure in the circuit.

c) Consider a slower speed.

d) Remove the motor and clean the impeller.

a) - Check that the motor is connected.

- Check the fuses of the installation.

b) Remove the motor and clean the impeller.

8.  OPERATING TROUBLE

Switch  the  circulator  OFF  before  doing  any

work on it
