MAINTENANCE OF HUMIDIFIER CYLINDER
The control does not measure the humidifier operating hours, however, lime scales must be periodically cleaned
off the steam cylinder.
Excessive lime scales can cause malfunctions or an alarm signal by the humidifier interface circuit.
Before the cylinder is removed for replacement or cleaning, water must be thoroughly drained from the boiler.
This command is not given directly by the
UG30/mP30
control, but by the
CDA303
circuit.
Note: To prevent tripping of the differential on the distribution panel,
dip-switch N°7
is turned ON: In this way, the CU contactor is de-
energised during discharge and, as a result, there is no current dispersion.
To open the solenoid discharge valve and empty the cylinder, you must switch the “MANUAL DRAINING” jumper
contacts on the CP1 card from GND-ON (automatic) to GND-DR (manual).
Attention: electronic components are sensitive to static charges emitted by the human body. Touch a grounding
facility before handling any electronic component.
- Open the humidifier thermal breaker;
- Clean or replace the cylinder;
- After cleaning or replacing the cylinder, re-position the component and restore normal humidifier operation.
