WATER LEVEL LIMITS
20
8.6.3 Extraordinary maintenance (water level limits substitution)
To replace the water level limits or parts of it, follow strictly the instructions below:
1. Ensure that the new ceramic plug is intact
2. Check the length of the rod
3. Ensure that the rod is coaxial to the plug axis
4. Inspect the electrical system and, in particular, ensure that the resistance of the electric circuit linking
the ceramic plug to the electrical panel is intact (resistance must be over 10 MOhm)
5. Ensure that the automatic level control consisting of the two ceramic plugs and their conductivity-relays,
work well
8.7 TROUBLESHOOTING
FAULT POSSIBLE CAUSE RECOMMENDED REMEDY
Interrupted water level monitoring Scaled stainless steel bar
Broken connection cable
Faulty safety level relay Temporary replace the safety electronic
relay with one of the two relays in the
panel.
If this is the problem, replace definitively
the faulty relay.
Safety intervention level 1 or 2
Water does not load See “Loading” inconv.
Blocked pump See. “Blocked pump” inconv.
Dirty pump sucking filter Clean the filter
Level regulation anomaly Temporary replace the safety electronic
relay with one of the two relays in the
panel.
If this is the problem, replace definitively
the faulty relay.
Level regulation probes short circuit Dismantle the adjustment probes to
inspect visually the ceramic insulation
Insufficient head (=different height
between the collecting vessel and the
pump levels) in comparison with water
temperature
Clean the pump sucking filter
Pump cavitatation
Decrease the pipe resistance between the
collecting vessel and the pump by
increasing the passage section
Insufficient water load
Pump sense of rotation Invert one of the two phases (three-phase
pump)
Incorrect electrical panel connection Consult the electric diagram
Faulty level safety relays See “Safety intervention level 1 or 2”
Check the pressure switches regulation
Burner always on
Regulation pressure and/or safety switches
OFF
Check the pressure switches connection
to the electrical panel
Burner problems See burner manual
Interrupted burner fuses Replace fuses
Lack of burner consent from the regulation
pressure switch
Replace regulation pressure switch
Lack of burner consent from the level safety
relays
See “Safety intervention level 1 or 2”
Burner always off
Incorrect electrical panel connection Consult the electric diagram
