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 slot-
ted 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.
Pump makes noises
• Check the differential pressure setting and re-set.
• Heating power too low, ways to increase it:
→ Increase setpoint,
→ Switch off night reduction,
To turn off the night reduction quickly (to check the setting),
it is sufficient to turn the setting button backwards and for-
wards slightly.
• If there are cavitation noises, increase the system supply
pressure within the permitted range.
If the operating fault cannot be correct, get in touch with
qualified firms in the trade or your nearest Wilo customer
support service or agent.
