5.2 Orientation of terminal box (see
FIG. 4)
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
cold water circuit.
5.3 Electrical connection
The electrical connect must be
madebyaqualied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
1.5mm
2
) to connect mains power to the
corresponding terminals of the circulator;
phase (L), neutral (N), and earth ( ) (see
FIG.5).
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3mm.Themotors
of the circulator models SC & SB are
self protected by impedance, therefore
theydon’tneedexternalprotection.The
motors of the circulators SS need a
contactorwithoverloadtted.Thepower
outlet must have an earthing contact.

6. STARTING UP
6.1 Filling, degassing
Never operate the circulator
WITHOUT WATER
- Open the valves on both sides of
thecirculatorandlltheinstallation
completely.
- Bleed the circuit at the high point.
- Bleed air from the circuit, by hand, by
unscrewingtheplug(seeFIG.6)afew
turns; close it when water runs out and
when there are no more air bubbles.
Risks of scald. Use a
screwdriver for unscrewing
the tap.
- Power up the motor to start the
circulator.

the speed of rotation of the motor using
the selector switch.
Risk of burning. In
operation, the motor casing
may be hotter than 100
o
C.
