Turning The Boiler Off - A.O. Smith Epsilon EB-40 User Manual

The boiler will not function directly. The automatic de-aeration programm of about
17 minutes will start after one of the three programm keys is pressed. The display
will show
and the number on the right indicates the actual water temperature of the boiler.
Check the water pressure regularly and top up the installation when neces-
sary.
The working pressure of the installation should be between 1.5 and 1.7 bar
It can take a while before all air has dis-appeared from a filled installation. Es-
pecially in the first week noises can be heard which indicate the presence of air.
The automatic air vent in the boiler will make this air disappear, which means the
water pressure will reduce during this period and therefore topping up with water
will be necessary to adjust the flow water temperature
