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. -
Page 5: Energy Saving
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. -

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. -

Page 13: Water Connection
Electric water heater EKA, EKR, EWH, EKL 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 fittings are used and if the stated operating pressure is exceeded. - Page 14 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.

Page 15: Pressureless Connection
Electric water heater EKA, EKR, EWH, EKL 13.2 Pressureless connection By using fittings for pressureless connection (overflow 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. -

Electric water heater EKA, EKR, EWH, EKL However, under no circumstances is it permissible to shut off the inflow 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. -
Page 18: Reconnection Possibilities
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. -

Page 21: Commissioning
Electric water heater EKA, EKR, EWH, EKL 16. Commissioning Before the device is switched on electrically, the storage tank must be filled with water. The expansion water produced in the interior tank during heating must drip from the safety valve (pressure resistant connection), respectively from the overflow mixer tap (pressureless connection). -
Page 22: Checking, Maintenance, Care
Finally, flush the device thoroughly (according to ÖNORM H5195-1) and observe the heating procedure as if the device was first-time commissioned. c) To make a justified claim under the warranty granted by AE-AG, the fitted protective anode must be checked by a professional at max. 2-year intervals. Do not damage or remove the protective current discharge resistor underneath the heater fastening screw during maintenance work. -
Page 23: Warranty
(e.g. doors and passages too narrow) are not governed by the guarantee and warranty declaration and therefore shall be rejected on the part of AE AG. If the water boiler is set up and operated in uncommon locations (e.g. attics, living rooms with water-sensitive floors, store rooms, etc.), the possibility of water leakage must be taken into account and provisions made for collecting and discharging the water leakage in order to prevent secondary damage within the meaning of product liability. - Page 24 8. Neither the performance of works under warranty or guarantee, nor the performance of service and mainte- nance works shall renew or extend the term of warranty. 9. Transport damage shall be investigated and possibly accepted only if it is reported to AE AG in writing on the next following workday after delivery at the latest.
