1 - General
1.1 - Application
This electric heating element is designed to heat sanitary water in a hot water storage tank or heating fluid in a
thermal store, incl. DUO Thermal Stores. This heating element is not designed to heat fluids in stainless steel
vessels.
1.2 - Installation
Screw the el. heating element into the respective threaded sleeve (G 6/4” F) with the cable gland pointing
downwards. Sealing cord, hemp, Teflon tape or semi-permanent thread sealant should be used to avoid leaks.
1.3 - Maintenance
Clean the exterior of the heating element with a soft cloth and a suitable detergent. Never use abrasive clean-
ers or solvents.
If the element is used in extra hard water, it is recommended to remove sediments at least once a year.
Unplug the element before cleaning. Then drain water from the tank and dismount the heating element.
Scratch the hard deposits on the heating rod with a plastic or wooden spatula and flush with water. Be careful
not to damage the protective nickel layer on the heating rod. Then reinstall the element according to this in-
struction manual, fill the tank with water, air-bleed and pressurize it. Check the threaded connection for leaks.
Finally, reconnect the heating element to the mains.
1.4 - Disposal

2.1 - Technical description
The electric heating element consists of a nickel-plated heating rod with G 6/4“ outer thread, a safety capillary
thermostat with manual reset in case of a temperature drop below 40 °C, set to 99 °C and +0 °C, -10 °C toler-
ance, 3× 1.5 mm² power supply cable with a connector. The power supply cable is 5 m long. IP 40 protection.

2.3 - Connection to power supply
The electric heating element connects to a solar controller connector 1/N/PE AC 230V 50Hz by a flexible
power cord. Do not use the element if the power supply cord or connector is damaged. All repairs shall be
performed by a specialized company.

2.5 - Commissioning, operation and possible faults
WARNING!
THE OUTGOING HOT WATER SHALL NOT BE LEAD THROUGH COMMON PLASTIC PIPES. THE PIPING
USED SHALL BE RESISTANT TO TEMPERATUREs OF 100 °C AT LEAST.
IF PLAIN COMMON PLASTIC PIPING IS USED, ITS SERVICE LIFE IS SIGNIFICANTLY REDUCED UN-
DER TEMPERATURES OVER 60 °C. WHEN COMBINED WITH IMPROPER PIPE FIXING THAT PRE-
VENTS/RESTRICTS ITS DILATATION, THE PIPE SERVICE LIFE MIGHT BE JUST SEVERAL HOURS!
IN ORDER TO TIGHTEN THE HEATING ELEMENT, NEVER GRASP ON THE PLASTIC BOX BUT USE
THE HEXAGON INSTEAD.
Water in direct contact with the heating element shall not exceed the values given in the chart below. The
manufacturer bears no responsibility for defects (e.g. limescale deposits on the heating element) caused by
unsuitable operation conditions.

2.5.2 - Heating fluid heating in a thermal store
Fill the heating system with heat transfer fluid, airbleed it and pressurize to the working pressure. Set the de-
sired temperature via the solar controller.
2.5.3 - Heating element state during operation
When the safety temperature is reached, the safety thermostat will cut off the heating element from power
supply. The safety thermostat features no automatic reset. After the tank cools down to below 40 °C, unscrew
the lid of the heating element and reset it by pressing the button. The heating element is ready again.
2.5.4 - Possible faults
If the tank gets overheated without any other heat source used (the solar controller probably does not turn off
the heating element when the set temperature is reached), call your service provider.
If the heating element shows signs of another defect, disconnect it from the mains immediately and call your
service provider.
2.5.1 - DHW heating in a hot water storage tank
In order to heat water in the hot water storage tank, open the cold water inlet, fill the tank with water and air-
bleed it by opening the hot water tap. Set the desired temperature via the solar controller.
It is recommended to set the temperature to 60 °C. This temperature guarantees the best operation of the
heating element, offering also:
- protection against Legionella
- cost reduction
- slower deposit formation
