Emptying
Emptying takes place through the safety valve’s overflow
pipe and is done as follows:
1 Switch off the power to the water heater.
2 Close the shutoff/non-return valve by turning
the knob (22) clockwise until it bottoms.
3 Turn the mixing valve’s knob (25) anticlockwise
to the maximum position.
4 Open the safety valve by turning the knob (23)
slowly anticlockwise a quarter turn until it
remains in the raised position.
NOTE! Water may splash by the overflow pipe.
5 Remove the venting screw (45) and open the
lowest placed hot water tap on the pipe system.
NOTE! Water may splash out of the venting
screw hole and could be hot.
Compressed air can be applied through the venting
screw hole to increase the emptying speed.
Maintain the position of the valves after the above ac-
tions until the water heater is to be used again.

Maintenance
Safety valve
The safety valve (23) should be inspected regularly, about
4 times a year, to prevent clogging.
The check is made by turning the safety valves knob
anticlockwise, water should then flow through the over-
flow pipe. If this does not happen then the safety valve is
defective and must be changed.
The safety valve sometimes releases a little water after
hot water has been tapped. This discharge is caused by
the expansion of the cold water taken into the water
heater, resulting in a pressure increase, whereby the
safety valve opens.
Sacrificial anode (only EMINENT-E)
The water heater is equipped with a magnesium anode
(40) that provides extra corrosion protection. The anode
is consumed partly by sacrificing itself for the pores in
the enamel, partly through self-consumption depending
on the chemical composition of the water.
Check the anode within a year. And then regularly in
relation to its use. When the anode is new it has a dia-
meter of approx. 21 mm. When the diameter has redu-
ced in its most used area to under 10 mm the anode is
consumed and must be replaced.
If anode consumption has not occurred after a few
years, this may be due to inferior conductivity in the
water and a water analysis is recommended.
Replacement/Inspection of the sacrificial anode
The anode can be replaced/inspected without the need
of emptying the water heater, when there is a hot water
tap on the pipe system located below the highest point
of the water heater. If there is not a hot water tap or
the hot water heater has been installed horizontally,
the hot water heater must be emptied, see the section
“Emptying”.
1 Switch off the power to the water heater.
2 Close the shutoff/non-return valve by turning
the knob (22) clockwise until it bottoms.
3 Open the hot water tap mentioned above.
4 Remove the plastic cover (3) and the insulation
plug, see the figure.
5 The sacrificial anode (40) is unscrewed using a
27 mm, or 24 mm, socket spanner.
To change anodes in confined spaces, there is a chain
anode available that only needs about 180 mm above
the heater. The chain anode can only be used in verti-
cally installed hot water heaters and should be cut as set
out in the table, see “Technical specifications”.
LEK
The anode is a consumable part.
NOTE!
Maintenance
The overflow pipe must be connected to
pos (43).
