The air outlet can be optionally mounted directly to a wall open- ing or to a longer duct (available as an accessory). Use the same mounting procedure as for the air inlet.

If a flange-mounted air duct is used on the air outlet side, it is se- cured with 4 M8 x 16 hexagon bolts in the threaded holes pro- vided. When doing this, ensure that the air duct stubs only touch the insulation. There should be no contact with the external sheeting.

Observe the external and internal dimensions as specified in the figure. Also ensure that the vibration and duct isolation are ade- quate.

6.3Heating System Connection

To enable connection to the heating system, flexible hose con- nection pieces and double nipples with a 1" external thread are included with the heat pump. These allow the optional use of a threaded or flat gasket connection to the heating system.

If the heat pump is not intended to be used to heat up the hot wa- ter, the hot water output must be permanently sealed using the supplied sealing plug.

Before connecting the heating water system to the heat pump, the heating system must be flushed to remove any impurities, residue from sealants, etc. Any accumulation of deposits in the liquifier could cause the heat pump to completely break down.

6.4

 

An overflow valve is installed in the device for systems in which

 

the heating water flow can be shut off via the radiator or thermo-

 

stat valves. This ensures a minimum heating water flow rate

 

through the heat pump and helps to avoid faults.

 

Once the heating system has been installed, it must be filled, de-

 

aerated and pressure-tested.

 

The integrated expansion vessel has a volume of 24 litres. This

 

volume is suitable for buildings with a living space area to be

 

heated of maximum 200 m².

 

The volume should be checked by the heating system engineer.

 

If necessary, an additional expansion vessel must be installed

 

(according to DIN 4751, Part 1). The tables listed in the manufac-

English

turers' catalogues simplify dimensioning the system on the basis

of the water content. Allow for a buffer tank volume of 80 litres

 

when making the calculation.

 

ATTENTION!

In the case of large-volume heating circuits, an additional expansion vessel must be used to supplement the installed expansion vessel (24 litres, 1.0 bar admission pressure).

Antifreeze

A method of manual drainage (see illustration) should be pro- vided for heat pumps which are exposed to frost. The antifreeze function of the heat pump controller is active whenever the con- troller and the heat circulating pumps are ready for operation. If the heat pump is taken out of service or in the event of a power failure, the system has to be drained. The heating circuit should be operated with a suitable antifreeze if heat pump systems are implemented in buildings where a power failure can not be de- tected (holiday home).

6.4Electrical Connection

The power supply and control voltage are supplied using stand- ard cables (load: 3-core, control: 3-core).

A disconnecting device with a contact gap of at least 3 mm (e.g. utility blocking contactor or power contactor) as well as a 1-pole circuit breaker must be installed in the power supply by the cus- tomer (tripping current in compliance with the Device Informa- tion).

The control voltage must be protected by a 10 A fuse. See Ap- pendix Circuit Diagrams for detailed information.

LIK 8MER specifications

The Dimplex LIK 8MER is a cutting-edge electric radiator that combines modern technology with stylish design. Designed to provide efficient warmth and comfort in residential settings, this heating solution stands out for its user-friendly features and high performance.

One of the main characteristics of the LIK 8MER is its advanced electronic control system, which promotes efficient energy usage. This system allows for precise temperature management, ensuring that your living space remains comfortable without excessive energy consumption. The radiator can be programmed to suit your lifestyle, with options to set different temperature levels for various times of the day or week.

The LIK 8MER is equipped with Dimplex’s unique Duo Heat technology, which enhances heat distribution throughout the room. This technology combines convection heating and thermal storage, allowing the radiator to store heat and release it gradually, ensuring consistent warmth. As a result, users experience a more stable and comfortable environment, devoid of the cold drafts often associated with traditional heating systems.

Another key feature of the Dimplex LIK 8MER is its sleek design. The radiator's minimalist aesthetic allows it to seamlessly integrate into any home décor, making it an attractive addition to both modern and traditional interiors. Available in various sizes, the LIK 8MER can easily fit in different spaces, whether it’s a living room, bedroom, or hallway.

In terms of safety, the LIK 8MER is designed with multiple features to ensure peace of mind for users. It includes overheat protection, which automatically turns off the radiator if it gets too hot, preventing any risk of fire. Furthermore, its surface temperature is kept at safe levels, making it suitable for homes with children or pets.

Additional technologies include a built-in timer and an intelligent learning function. The timer allows users to set the radiator to turn on or off according to their schedule, while the learning function adapts to the user’s habits, optimizing energy use based on past behavior.

Overall, the Dimplex LIK 8MER electric radiator is a perfect blend of technology, efficiency, and style. Its innovative features and thoughtful design make it a practical choice for anyone seeking to enhance their home heating experience. Whether you are aiming to save on energy bills or simply seeking reliable warmth, the LIK 8MER delivers on all fronts.
