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 innitely 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 specications 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 ofces or our main ofce).

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.

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 calcied 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.

Id.Nr.: 228843-13

Electric water heater EKA, EKR, EWH, EKL

13.2 Pressureless connection

By using ttings for pressureless connection (overow 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 overow 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 (overow 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 inow line to prevent backheating into the

heating circuit when the central heating is switched off and electric operation is active.

Id.Nr.: 228843-13

Electric water heater EKA, EKR, EWH, EKL

However, under no circumstances is it permissible to shut off the inow 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).

Electric water heater EKA, EKR, EWH, EKL

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.
