MAINTENANCE

5 MAINTENANCE

5.1 ORDINARY

• Periodically purge the level gauges, probe holder if fitted and the boiler, to avoid the accumulation of

sludge;

• Check the efficiency of the control and regulation instruments, examining carefully the electrical parts

(connections included) and the mechanical parts (pressure switches); it is advisable to replace every

year the ceramic probe-holders;

• Carry out burner maintenance (as to the specific instructions);

• Check the tightness of flange bolts and the state of the gaskets;

• Check the conditions of the boiler door internal covering;

• Clean the flue-gas tube bundle and the turbolators;

• Carry out correct maintenance to the pump (bearings, mechanical seal),

• Check for wear to the discharge valves; these tend to wear more quickly, due to the abrasive effect of

the sludge during blow-down.

5.2 PERIODIC

5.2.1 Periodic control (every 6 hours of use)

From time to time (every 6 hours of use) the thermal plant must be inspected by qualified personnel to check

the efficiency of all safety accessories:

• Safety pressure switch

• Water level limits

The system can be reset if no anomalies have been encountered: power off the panel for approx. 20

seconds, power on the main switch and press the reset buttons.
