a) During the heat-up phase the expansion water must drip noticeably from the safety valve drain. When fully heated
(~ 80° C) the expansion water makes up approximately 3.5% of the rated capacity of the water heater.
Regularly check for proper function of the safety valve. When lifting or turning the safety valve test knob to the "Test"
position, the water must flow unhindered from the safety valve body into the funnel.
Caution: The cold water inlet and parts of the water heater fitting can get hot during this process. If the tank is not hea-
ted up or hot water removed, no water is allowed to drip from the safety valve. If this is the case, either the water line
pressure is greater than the permitted value (in Switzerland more than 6 bar) or the safety valve is defective. If the water
line pressure is greater than permitted (6 bar in Switzerland), a pressure reducing valve must be used.
b) If the service water has a high lime content, removal of the scale formed in the interior boiler as well as of the free lime
particles must be performed by a technician every one to two operating years. Cleaning is done through the flange
opening – remove heater flange, clean tank, and use a new gasket when reassembling the flange. The screws must be
tightened in a cross pattern with a tightening torque of 20 Nm - 25 Nm. The special enamelled inner container of the
water heater must never come into contact with scale solvent. Do not work with the decalcification pump! Then flush
the unit thoroughly and perform the heat-up cycle as for initial startup of the unit.
c) To make a proper warranty claim as provided for by AE-AG, the installed sacrificial anode must have been inspected and
this inspection documented by a technician at intervals of no more than 2 operating years. During maintenance works,
it is advisable to open the cleaning and service flange in order to check the tank for any possible washing-in of foreign
objects and contaminations, and to remove these if necessary.
The external current anode has a virtually unlimited life expectancy. Its function must be regularly checked by noting the
inspection lamp. This indicates two conditions:
green: System OK.
flashing red: Fault: Contact customer service!
The prerequisite for proper function is that the container is filled with water. Conductivity of at least 150 μs is required to
ensure that the external current anode functions properly.
d) The area in which the unit is operated must be kept from freezing. The unit must be installed in a location where it can
be easily accessed for maintenance, repair and possible replacement. When water with high lime content is used, we
recommend installing a commercially available water softener, since the natural calcium formation is not a basis for any
claims under the terms of the AE-AG warranty. For proper operation of the water heater a corresponding potable water
quality which meets national codes and laws (such as the Federal Ordinance on the Quality of Drinking Water TWV;
Federal Law Gazette II Nr. 304/2001) must be used.
