18.3 Low pressure interlock
When this interlock occurs, the alarm code "E-19" will appear on the display. The burner and the boiler
circulation pump will switch off, cutting off the heating and water flow to the installation.
This interlock occurs when the boiler pressure drops to below 0.5 bar, preventing the boiler from
functioning when the water is drained from the installation, due to either leakage or maintenance
operations. To unlock this alarm, fill the installation again
(see "Boiler Filling") , until the "water pressure"
parameter of the
“User Menu”
shows a pressure of between 1 and 1.5 bar.
19 SHUTTING DOWN THE BOILER
To switch off the boiler, place your finger on the power touch button for 1 second
(see "Hand
Components")
. In the Off mode , while the boiler is plugged into the mains and connected to the fuel
installation, the boiler will stop operating, but the anti-frost protection and pump anti-block functions will
remain activated.
To shut down the boiler functioning completely, unplug it from the mains and cut off the fuel supply.
20 DRAINING THE BOILER
The boiler has an outlet for drainage. The water is drained from the boiler by opening the drain valve
located on the lower rear part of the boiler (the valve is not supplied with the boiler). Connect a flexible
tube to this valve and run it to a drain. After draining the boiler, close the valve again and remove the
flexible tube.
