GENERAL COMMENTS
Generator operation is completely automatic and requires nothing in particular.
The operations to be performed regularly are indicated in the section below.
Carrying out the programme of checks and inspections proposed here means extending the system’s lifetime
and preventing possible faults and malfunctioning.
Daily operations
•
Check the regulator ignition cycle.
•
Check the boiler supply water hardness.
•
Check purifier cycle. If necessary regenerate.
•
Check water supply pump delivery pressure.
•
Check whether the self-cleaner naphtha/gas filter is clean (turn upper filter handwheel).
•
Check smoke thermostat safety lock.
•
Check steam thermostat safety lock.
•
Discharge the generator under pressure (only for vertical generators).
•
Check supply pump belt tension.
Weekly operations
•
Clean nozzle and ignition electrodes.
•
Check tank fuel level.
•
Check naphtha pre-heater temperature.
•
Check operation of supply water tank float level regulator.
•
Check water supply pump oil level.
Monthly operations
•
Clean water supply pump suction filter.
•
Clean burner outflows.
•
Clean photocell and protective glass.
•
Drain slime out of the water supply tank.
To protect the generator during a short shut-down period proceed as follows:
Discharge the coil under pressure.
Close the on-off valve water supply and the steam intake valve. Keep the relief valves of the coil and humidity
separator (for vertical generators) open, wait for the generator temperature to drop to about 50°C and then
close the relief valves.
To protect the generator, with seasonal working with long shut-down periods, follow the precise information
given in the instruction sheet enclosed.
WARNING: before performing any maintenance operation, switch the unit off by
means of the switch upstream of the line, and the main switch on the control panel.
Put the sign:
“ MAINTENANCE IN PROGRESS or STOPPED FOR MAINTENANCE”.
on the switches
