Electric water heater EKA, EKR, EWH, EKL
1. Function
The water stored in the enamelled interior tank is heated by an electrical heater insert. A
user-adjustable knob is available to preset the desired temperature. At the times determi-
ned by the responsible power supply company, the temperature controller automatically
switches on the heating. Once the desired temperature in the storage tank is reached,
the temperature controller switches the heater off again. If the water temperature drops,
for instance because water is used up or as a result of natural cooling (an effect that is
minimised by the high-quality CFC-free PU foam insulation), the heating will switch on
until the preset storage water temperature is reached again.
If the storage tank is equipped with a heater battery (EKR), the water may be heated with
the system’s water heater as an alternative to electrical heating.
2. Hot water requirement
The hot water requirement of the household depends on the number of persons in the
household, the sanitary installations of the at or house, the insulation, the piping and
the individual user’s habits.
The following table provides a list of standard consumption values for orientation.
In this table, it was assumed that the temperature of the cold water required for mixing
to the indicated hot water temperature is approximately 12°C.

3. Energy saving
The high-quality CFC-free PU foam insulation and the tted temperature control means that
our electric storage tanks are genuine energy savers.
Low storage water temperatures are especially economic. Therefore, the innitely variable
temperature setting should be set to the lowest value that is actually required to cover the real
hot water requirement. This helps save energy and reduces the build-up of limescale deposits
in the tank.
4. Standby energy consumption of the individual series
If no water is used for a long time after the end of the water heater’s heating interval, the water
in the tank will cool down slowly but continuously due to losses at the unit’s surface.
The speed of this cooling process depends on the type of device, its size, the thickness and
the quality of the tank insulation.
This behaviour is measured during a 24-hour period at a storage water temperature of 65°C,
considering the energy input in kWh that is necessary to keep the water temperature constant
during this period.

5. Operation
All operating elements required for the operation of the electric storage tanks (EWH, EKA,
EKR) (button to adjust the temperature controller) and monitoring elements (operation indi-
cator lamp and thermometer) are included in a control panel on the front wall of the device.
Wall-mounted storage tanks (EWH, EKL) do not have an operation indicator lamp.
The button to adjust the temperature controller of the horizontal storage tank (EKL) is located
on the front (connection side).
This device is not designed to be used by persons (including children) with physical, sensory
or mental disabilities or lacking experience and/or lacking knowledge, unless these are
supervised by a person who is responsible for their safety or have received instructions on
how to use this device from any such person. Children should be supervised in order to
ensure that they do not play with this device.

6. Temperature setting
For easier adjustment, the button to adjust the temperature controller of the electric heater
has 4 main settings. These are:
Setting: Protects the storage tank against freezing (up to 30 °C)
Approximately 40°C, hand-hot storage water
Approximately 65°C, moderately hot storage water – it is recommended to
use this setting to prevent accidental scalding with excessively hot water.
If this setting is selected, the operation of the device is extraordinarily eco
nomical.
Heat losses are small and the build-up of limescale is largely prevented.
Low standby energy consumption.
Approximately 85°C, hot storage water
N.B.:
Setting the control button all the way to the left does not switch off the heater (no zero setting).
If the device is operated on daytime current, it is recommended to set the temperature cont-
roller to max. “Pos ” ( approximately 65°C).
Due to the hysteresis of the temperature control (± 7°K) and possible radiation losses (cooling-
down of the pipelines), the temperature specications are subject to an accuracy of ± 10°K.

7. Thermometer
To monitor the storage water temperature, types
EWH, EKR, EKA are equipped with a remote
thermometer. The displayed value depends on
the temperature controller setting. The maximum
display value is reached only if the control button
is set to “Pos. ” at the end of the respective hea-
ting cycle.
If any other controller setting is chosen, the poin-
ter will indicate a lower temperature value.
8. Setting range limitation (EWH, EKR, EKA)
In order to exclude the risk of accidental scalding
with hot water, the setting range of the tempera-
ture controller can be limited to max. 65°C. Elec-
trically disconnect the device from the mains (all
poles must be disconnected). Set control button
to “Pos. “. Open the connection chamber and
pull out the bolt from the bore in the back wall of
the control panel. Reinsert bolt in the bore, inser-
ting the long shaft first.
9. Prerequisites for operation
The storage tanks must be used exclusively in accordance with the conditions specified on the
rating plate. In addition to national regulations and standards recognised in the laws, compliance
with the connection conditions of the local electricity company and water supply works as well as
the installation and operation instructions is required.
The room where the device is operated must be free of frost. The device must be installed in a re-
asonably expected location, i.e. if the device needs to be maintained, repaired or replaced, it must
be readily accessible. If the water is very hard, either of the following options is recommended: to
connect a commercially available standard descaling device upstream of the tank, to use an anti-
scaling tank of Austria Email AG or to observe a maximum operating temperature of approximately
65°C (setting “Pos. ”). The bare-tube heat exchanger of the EKR series must be flushed properly
before the initial installation is performed. If the bare-tube heat exchanger is not used, the outer tube
ends must be sealed to prevent back-cooling. The drinking water quality must be appropriate to
ensure proper operation.
It is recommended to fit a water filter upstream of the device to keep the tank free of dirt and other
particles.
Should a device, at the point of delivery, clearly display a malfunction, damage or other defect,
this must not be fitted, installed or used in the system. Subsequent complaints regarding devices
with an obvious defect which have been connected and installed are expressly excluded under the
warranty and guarantee.

10. Installation and safety advice
a) Important installation advice! Do not bend the hook, otherwise it could
break. A failure to observe this warning can cause injury as the device
may fall down!
b) To mount the upper hook, a wall rail is provided with every device.
The wall rail, which carries the device, is mounted on the wall with
two screws. Two further screws are required (reference is made to the
drawing stating the dimensions of the device) to fasten the lower wall
bracket of the device to the wall. However, this bracket only provides
support against the wall and prevents side-to-side movements. Do not
mount wall-mounted water heaters horizontally.
c) The distance between the hooks – i.e. mounting dimension A - can be changed at 50mm
intervals by inserting the screws in the back wall of the storage tank in different bores of the
hook (only 50 - 150 litres).
Caution: Do not use any other hook than the hook provided by AE!
d) With regard to the installation of the device, it is necessary to observe the dimensioned dra-
wings of the device and the enclosed indicating labels, if any.
e) Caution: In order to ensure that the mounting surface for the device and the choice of the
place of installation are appropriate in consideration of the load to be supported and the
strength of the mounting surface, it is necessary to take into account both the weight of the
water heater and the weight of the water inside the heater (i.e. of the nominal content).
Special installation systems: see thin wall and ceiling installation.
f) If an envelope (or jacket) is tted to a water heater or if the water heater is tted in small nar-
row rooms or in suspended ceilings and similar, always ensure that the connection side of
the device (water connections, electrical connection chamber resp. heating insert) are freely
accessible and that there is no accumulation of heat. To remove the heating ange, a free
space of 500mm must be available. To hook up the device in the wall rail, ensure that there
is a minimum clearance of 50mm on top of the device.
g) With regard to the choice or sequence of the installation materials used at the site of the
installation (caution is required with mixed installations), it is necessary to consider the latest
information concerning possible electrochemical processes (contact corrosion, e.g. copper/
steel). The use of insulation grade screw connections is recommended.
h) If the water is particularly aggressive and requires special solutions at the site of installation, it
may be necessary to consider the use of special versions of the storage tank (please consult
our representation ofces or our main ofce).
i) Horizontal storage tanks: The tting situation for horizontal tanks is determined by the func-
tion and must therefore be observed strictly. The cold water inlet (blue) and the hot water
outlet (red) should be located next to each other on the same level and protrude in the lower
part of the housing cover.
j) The device is equipped with a safety temperature limiter that will switch off further heating
once the water has reached a temperature of max. 110°C (EN 60335 -2-21; ÖVE-EW41,
Pt 2 (500) /1971). Therefore, when it comes to choosing the connection components (con-
nection pipes, safety valve combinations etc.), it is necessary to ensure that the connection
components are able to withstand a temperature of 110°C in the event of a malfunction of
the temperature controller so that possible damages are prevented.
k) Assembly and installation must be performed exclusively by authorised professionals.

13. Water connection
13.1 Pressure resistant connection
Any warranty for our water heaters is rendered null and void if unsuitable or non-func-
tioning storage tank connection ttings are used and if the stated operating pressure is
exceeded.
Water heaters whose rating plate states a nominal pressure of 6 bar (atü or kp/cm2) are
pressure resistant storage tanks. In this case, a closed connection with a line pressure
of up to 5.5 bar (atü) is permitted. However, if the line pressure is higher, a pressure-
reducing valve must be tted in the cold water supply line.
Use only tested diaphragm safety valves or a diaphragm safety valve combination - con-
nection tting for pressure resistant storage tanks - for the water connection!
A safety valve combination consists of stop valve, test valve, non-return valve, drain valve
and safety valve with expansion water drain. It is tted between the cold water supply line
and the cold water inlet (blue) of the storage tank in the indicated order.
As a general rule, the following should be observed:
A faultless function of the connection tting can only be guaranteed if it is installed in a
frost-protected room. The drain of the safety valve must be open and observable. To
prevent disturbances and clogging due to frost or dirt and similar, do not lead the drain
line from the drip catcher (expansion water funnel) into the open.
Furthermore, the drainpipe of the safety valve must be installed with a continuous down-
ward inclination.
It is not permitted to t stop valves or another reducer between the safety valve and the
cold water inlet of the storage tank.
The response pressure setting of the safety valve must be lower than the nominal pres-
sure (6 bar) of the storage tank. The discharge openings of the safety valves (domestic
water and heating circuits) must open out into an appropriate drainage object in order to
avoid any damage caused by the escape of operating uid.
Before the nal connection of the storage tank, the cold water supply line must be
ushed.
Once the water is connected and the storage tank is lled with (bubble-free) water, it is
necessary to check the function of the connection tting.
14
Id.Nr.: 228843-13
Electric water heater EKA, EKR, EWH, EKL
a) To avoid limescale deposits from obstructing the air introduction system of the safety
valve, operate the air introduction system of the safety valve from time to time during
the operation of the facility. Check whether the valve closes once the air introduction
system is released and whether the water drains completely through the funnel or
the bleeding line.
b) Where safety valves are tted in front of water heaters, observe if the safety valve
responds when the water heater heats up. This can be ascertained by checking that
water exits the bleeding line.
To be performed by: Operator, installation company
Interval: every 6 months
Maintenance and repair:
If no water exits when the water heater heats up or if the safety valve permanently leaks,
try to activate the air introduction system repeatedly to get the valve unstuck or ush
out foreign matter (for instance limescale particles) that might obstruct the sealing part.
If this is not successful, get an installation company to carry out the repair. If the valve
seat or sealing shim is damaged, the safety valve must be replaced completely.
To be performed by: Installation company
Interval: once per year
To check the non-return valve, close the stop valve. If water exits through the open test
valve, the non-return valve does not function properly.
The operation of the storage tank is effected by the hot water valve of the tting (mixer
tap). Therefore, the storage tank is constantly exposed to line pressure. To protect the
interior tank against overpressure during the heating process, the expansion water is let
off through the safety valve. To avoid overpressure damage to the water heater, it is very
important that calcied safety valves are replaced. In the event of a line pressure drop,
the non-return valve prevents the hot water from owing back into the cold water supply
network. In this way, the boiler is protected against heating without water. The stop valve
allows the storage tank to be separated from the cold water supply network, shutting
out the water and pressure. If required, the storage tank can now be drained through
the drain valve.
15
Id.Nr.: 228843-13
Electric water heater EKA, EKR, EWH, EKL
13.2 Pressureless connection
By using ttings for pressureless connection (overow mixer taps), it is also possible to
make a pressureless connection for a pressure resistant storage tank.
In the cold water supply line, no safety valve is required. However, a non-return valve, a
stop valve and a drain valve are required!
This type of connection is advantageous if only one hot water tapping point is needed.
The operation of the storage tank is effected at the tting (mixer tap) by the hot water
valve – it acts as a shut-off element in the cold water inlet of the storage tank. This means
that the retrieval of hot water from the storage tank works as follows: by opening the
hot water valve, cold water is pushed into the storage tank from below, allowing the hot
water to exit freely through the upper hot water drain via the overow mixer tap.
The ttings for pressureless connection are built in such a way that the hot water drain
always stays open, even if the hot and cold water valves are closed. Therefore, there is
always a connection between the storage tank and the outside air. The expansion water
produced by the heating procedure can ow out freely through the hot water drain.
Where required, the stop valve can be used to separate the storage tank from the cold
water supply network. The tank can now be drained through the drain valve.

Id.Nr.: 228843-13
Electric water heater EKA, EKR, EWH, EKL
13.3 Connection storage tank with 3 connecting pieces (EKA)
The hot water and the cold water sides of the storage tank are connected to a tting for
pressureless connection (overow mixer tap).
Any number of pressure resistant ttings may be supplied from the third connecting pie-
ce. At these taps, approximately 1/3 of the content of the storage tank can be consumed
as hot water of the same temperature. Renewed lling is required before the rest of the
storage tank water is available through the pressureless tting.
To avoid damage, it is necessary to construct the connection of the storage tank with a
detachable connection (union).
Leaks from the storage tank as a result of an improper connection and damage and con-
sequential damage caused by this are excluded from the guarantee and product liability.
14. Central heating connection (only EKR)
The heat exchanger is suitable for connection to a water heater at a pressure of up to
6 bar. A forced circulation with pump is required. If the storage tank is connected to
alternating current, the pump can be controlled via the free charge pump contact. The
temperature setting of this contact is identical to the temperature level of the two con-
tacts for the tted electric heater.
The bare-tube heat exchanger of the EKR series must be ushed properly before the
initial installation is performed. If the bare-tube heat exchanger is not used, the outer tube
ends must be sealed to prevent back-cooling.
In the event of a combination with boilers or gas red water heaters, an additional sen-
sor protection tube (clear width 9.5mm) is tted in the heating ange for insertion of the
sensor (to be provided on site – capillary tube or electronic sensor). The sensor tube
protrudes above the topmost coil of the heat exchanger.
If a hot water storage tank with bare-tube heat exchanger is installed, a shut-off element
or circulation brake should be tted in the inow line to prevent backheating into the
heating circuit when the central heating is switched off and electric operation is active.
17
Id.Nr.: 228843-13
Electric water heater EKA, EKR, EWH, EKL
However, under no circumstances is it permissible to shut off the inow line and the re-
turn line because this would make it impossible for the water inside the heat exchanger
to expand, which could damage the heat exchanger.
If the water heater is heated by its heat exchanger, then it must be ensured that in no
case the hot water temperature exceeds 85 °C, as otherwise the safety temperature
limiter of the electric heater can trigger and render it inoperable.
15. Electrical connection
15.1 General information
a) As a general rule, the electrical connection must be made in accordance with the
wiring diagram glued inside the connection chamber of the storage tank!
b) Ensure that the supply voltage is correct!
c) Fit an all-pole disconnector with 3mm contact opening width in the electric feeder.
Automatic circuit breakers can also be used as disconnectors.
d) The connection cable must be fed through the cable screw connection into the con-
nection chamber of the storage tank and protected with a strain relief mechanism
against pulling out and twisting. Tanks with heater battery have a second cable entry
point for the charge pump control cable.
e) For installation and intrusive interventions into the device, the hot water storage tank
must rst be isolated completely (all poles) and on every side from the power supply
in compliance with EN 50110 (ÖVE, TAEV). Before carrying out any additional work,
the system must be secured against being switched on again (remove the fuses,
trigger the mains circuit breaker).

15.2 Reconnection possibilities
For storage tanks with choice of heating time, the heating elements must be recon-
nected according to the wiring diagram glued inside the unit. The factory connection
corresponds to a heating time of 6 hours in ~ 230 V supply voltage. The three-phase
current circuits 3 ~ 400 V, respectively 3 N ~ 400 V, available as an option for 100 litres
and above, must also be reconnected according to the following table.
