Installation or removal

Detailed information demonstrating the different ways of installing or removing a radiator heating element is available from the manufacturer or importer (see footnotes at the end of the manual). Below we list some basic requirements and principles which must be followed to ensure the long-term, reliable operation of the product.

Before installation or first use

1. Read the chapter Safety requirements Installation.
2. Fit the heating element using the correct spanner (size 22).
3. The heating element must be installed at the bottom of the radiator, perpendicular to the radiator pipes while preserving space for the proper circulation of the heating medium.
4. Use a suitable heating medium for filling the electric radiator, i.e. (water, special products based on water and glycol for use in central heating systems, or oil that complies with the requirements of the manufacturer of the radiator and heating element).
5. Do not switch the heating element on if it is not fully immersed in the radiator heating medium.
6. Make sure an adequate air cushion is present to protect against excessive pressure build-up within the heater (always leave one of the radiator valves open).
7. When filling the radiator with hot liquid ensure that the liquid temperature does not exceed 60° C.
8. Follow the subsequent guidelines when connecting the electrical installation:
   • Brown wire — live connection to the circuit (L).
   • Blue wire — connect to neutral (N)
   • Yellow & green wire — earth connection (PE).
9. Before filling the radiator with a heating medium, ensure that the heating element is fitted properly and that it is water tight.
10. In central heating, the installation radiator must be fitted with the valves enabling disconnection of the radiator from the rest of the system.
11. The temperature of the heating agent in the central heating system must not exceed 82° C!

Notes prior to removal

1. Before dismantling permanently, disconnect the heating element from the mains and ensure that the radiator is not hot.
2. Be aware. A radiator filled with liquid can be very heavy. When moving the radiator, ensure that you take the necessary safety precautions.
3. Before disassembly, close the appropriate valves and drain the radiator completely to avoid causing any damage.

Product disposal

This product should not be disposed of as general waste but should be brought to the appropriate collection point for the recycling of electric and electronic devices. This information is provided by the sign on the product, user manual and packaging. Information on the appropriate point for used devices can be provided by your local authority, product distributor or the store from where the product was purchased. Thank you for your effort toward protecting the environment.

Maintenance

• Before performing maintenance, always unplug the unit from the mains system.
• Periodically check the fluid level in the radiator and ensure the heating element is completely submerged.
• Clean the product with a dry or damp cloth. I f necessary, use a very small amount of detergent, ensuring that it contains no solvents or abrasives.

Basic Operation

Pressing the key switches the heating element on and the radiator will warm up to an average temperature of approximately 43°C. On the control panel blue LED lights up to indicate the current (ON) status of the heater.

Please note: the surface temperature of the radiator will not be constant and may vary in places.

This is a normal phenomenon and it is due to the design of the heating element, the physical properties of the heat transfer medium in the radiator as well as other physical phenomena (convection and diffusion).

TIMER function

Pressing the key activates a 2-hour timer. The timer function automatically turns the heater off after 2 hours. Active timer mode is indicated by a red LED located near the key. Pressing the key again during 2hr timer mode operation disables the TIMER and reverts the heating element.

Please note: pressing the ON/OFF key switches during the timer mode deactivates the timer and switches the heating element off.

ANTIFREEZE function

As long as the heating element is connected to the mains power supply 43D heating element temperature sensor continues to control the heating medium temperature. The antifreeze function remains active even when the heater is turned off. As soon as the temperature around the sensor falls below 6°C heating element will switch on automatically preventing the heating medium inside the radiator from freezing. Activation of the ANTIFREEZE function is indicated by slow blue LED flashes (every 3 sec.).

Fault Indication

The heating element has built-in protection against a risk of overheating while running in a dry radiator. This does not eliminate the possibility of temperature sensor failure. MOA 43D will display a temperature alert by means of a flashing blue LED (every 1 sec.). The alert does not mean the unit is damaged, it informs the user that the set operating temperature has been exceeded for unknown reasons.

Troubleshooting

Connection problem.
