Check the pressure gauge
(Twice a year)
The pressure gauge in the lower section of the electric boiler must be
checked twice a year. This is particularly important during autumn when
the heating season starts. The pressure gauge should be at 0.5 – 1.5 bar. If
the pressure is lower than 0.5 bar, fi ll with water up to around 1.0 bar. The
knob for topping up the heating water is located in the connection area.
Clean the discharge water vessel
(Twice a year)
Wash the discharge water vessel with warm water and anti-bacterial
cleaning agent to remove dirt and algae. Rinse and check that the water
runs off through the hose.
Check the safety valves
(Twice a year)
Check the safety valves for tap water and heating water by opening and
closing them using the valve knobs.
Water may drip from the escape pipe, this is normal. The pipe opening must
never be sealed.
If the hot water heater must be drained, call a service engineer.
