CAUTION ! Risk of damage to the pump !
The pump may jam with the plug screw open
depending on the operating pressure. Close the
bleeder screw again before switching on.
Refermer la vis de dégazage avant de remettre la
pompe en marche.
- Close the bleeder screw again,
- Open the shut-off device again,
- Switch on the pump.
8.2 Selection of pump flow rate
- Select the control mode (see 6.1).
- Preselect the pump output (delivery head)
depending on the need at the setting knob (Fig. 1,
item 2).
- If the nominal delivery head is not known, we
recommend starting with the setting 1.5 m.
- If the heating output is not adequate, gradually
increase the set value.
- If the heating output is too high, or flow noises occur,
gradually reduce the set value.
- Select automatic night reduction mode, i.e. switch
on or off (see 6.1).
9. MAINTENANCE
Maintenance and repair work should only be carried
out by qualified specialist personnel !
WARNING ! Danger of electric shock !
Prevent dangers through exposure to electrical
currents.
For all maintenance and repair work, the pump must
be switched off. It must not be possible to switch it on
again without authorisation.
In principle, damage to the connection cable must
only be repaired by a qualified electrician.
10. FAULTS, CAUSES AND REMEDIES
Pump does not run with the power switched on :
- Check the mains fuses,
- Check the voltage at the pump (check name plate
data),
- Pump blocked:
• Switch off the pump.
WARNING ! Risk of scalding !
Depending on the temperature of the fluid and
system pressure, hot liquid or gaseous fluid may
escape or shoot out at high pressure at the bleeder
screw. There is a risk of scalding!
• Close shut-off devices upstream and downstream
of the pump and allow the pump to cool down.
Remove the bleeder screw. Check the movement of
the pump by turning the slotted rotor shaft with a
screwdriver and release.
• Switch on the pump.
• If the blockage does not correct itself
automatically via the automatic release routine, see
the manual procedure described above.
Noisy pump operation
- Check differential pressure setting and adjust
respectively.
- Heating capacity too low, possibilities to increase:
• Stepp-up setpoint value,
• Switch off night setback.
To briefly switch off night setback mode (check on
control operations) it is sufficient to just turn the dial
button a little.
- On cavitation, increase system pressure within the
permissible limit.
If no solution can be found, please contact your
plumbing and heating specialist or your nearest
SALMSON Customer Service or representative.
