Maintenance recommendation
Controller
We recommend performing a regular complete functional test of the system, preferably before the onset of winter, to check that the
entire antenna heating system is operating correctly (see
“Controller functional test” on page 6
).
Sensor system
Once a year, preferably before the onset of winter, the sensors should be wiped over with a moist cloth to remove any heavy dirt.
Heating plates / heating pads
The heating plate or heating pad should be checked for damage at regular intervals to ensure they are in sound condition. Other than
this, the heaters are largely maintenance free once installed.
