Fault-Finding Chart - Lamborghini Caloreclima EM 50/M-E Manuel D'utilisation

START UP
Open the gas cock and set the desired temperature on the boiler adjustment thermostat.
The equipment will start the automatic check-out test and then the burner will ignite automatically. Should the start up not
perform - lock-out button lit - push this button so that the equipment can repeat the automatic check-out test.
PROLONGED SWITCHING OFF
If the burner should remain inactive at length close the gas cock and turn off the power by acting on the main switch.
MAINTENANCE
Skilled staff has to perform yearly the following operations:
- Check the valve inside tightness.
- Filter cleaning.
- Fan and head cleaning.
- Check the position of the ignition electrode tips as well as the control electrode.
- Calibrate the air and gas pressure switches.
- Check the combustion by means of CO
- Check all the gaskets and seal tightness.

REMEDY
A. Check the main fuses.
Check the control box fuse. Check
thermostats line and gas pressure
switch.
B. Check that the interception devices
positioned along the feed pipe open
properly.
A. Check valves operation.
B. Check ignition transformer ope-
ration, check the electrode tips
position.
C. Check the calibration and the ope-
ration of the air pressure switch.
