3. Safety instruction

Warning! With the purchase of the product, you need to make sure that the packaging has not been damaged during the transportation. In case of any defects return the product to the supplier without opening the package!

The connection of Salmerk underfloor heating to the power supply must be performed only by a qualified electrical specialist in accordance with the instructions and local wiring rules. It is forbidden to connect the system to power supply until all elements are fully installed and system electrical circuit integrity is checked and is complied with the instruction. For safety reasons, the system shall be connected to a residual current device (RCD). During the installation process, Salmerk system or its separate components shall not be exposed to oil, grease or other chemically aggressive substances. It is forbidden, even for the short moment, to connect to the electric power system rolled up the heating strip. Avoid excessive flattening of network and central system unit wires. It is not allowed to lay the heating tape in the places of installation of built-in or other furniture with a solid base on the floor. The surface of furniture items placed above the heated area should be at a height of at least 8 cm above the floor level to ensure air circulation. The heating strip is installed at 20 – 30 cm distance from each wall (this requirement does not apply to bathrooms). Before heating strip installation, clean and vacuum the floor surface. It is not recommended to walk on the heating strip during its installation. In case of necessity, use clean shoes with a soft bottom.

Make sure that there are no sharp items (nails, clamping irons, etc.) on the floor surface, as well as other barriers that could damage the heating strip. Make sure that connections, power wires, transformer, electronics modules, regulator, and heating strip are securely connected. Do not install the system if the room temperature is below + 5°C. Do not cut the heating strip! In case of over measured strip, place it in the most passable place with a smaller distance between strips. If there is a shortage in the least passable place, lay the strip with a long distance between the lines of the strip.

Prevent children from access to the system! It is forbidden to open, disassemble the built-in control and transformer unit, as well as to replace parts or make the repair on your own.

Warning! These instructions are subject for mandatory performance during mounting and installation of any Salmerk system. Instructions should be given to the specialist who is carrying out any work with the system. Failure to comply with these instructions may cause damage to the product and warranty cancellation. Be careful, noncompliance with safety rules can lead to injury or other damage!

6. Transportation and storage  

Transportation and storage of the unit are allowed only in original packaging form. In order to prevent damage to the heating strip, do not open wrapping outside the installation place.

7. Installation planning 

• Determine the heating area (deduct from total area of the room the location of the furniture without legs, household appliances, etc. (see the figure), but if you plan further furniture rearrangements, for more comfort we recommend placing the heating element on the whole premise area, while doing that the furniture must meet the safety requirements specified in paragraph 3 herein);
• Select the Salmerk unit for useful floor area. For more comfortable temperature regulation, we recommend installing separate units in different rooms, especially in rooms with large heat losses (large glazed area, high ceilings, enclosed balcony, bathroom);
• Make sure that the rough floor surface on which the heating strip is to be installed is smooth and free from dust.

8. Electric installation

• Check if available electric circuit wiring in the object has an additional power connection. The nominal power of each unit is given in the table of technical characteristics;
• Take into account additional electrical devices which can be connected to the same network. Also, check the permissible current of the safety devices (automatic circuit breaker);
• Each Salmerk unit shall be connected via special circuit wiring and a separate 16A automatic circuit breaker (RCD with operating current not more than 30 mA).
• Select the placement of the thermostat in the heated room, remember, the thermostat is a thermometer, it measures the temperature of the air in the room in which it is located. Usually, it is installed on the wall at a height of 140-160 cm from the floor, in the most convenient place and in a way not to interfere with furniture arrangement.
  

9. Underfloor heating installation

It is important to note that durability and safety of heating system operating by 99% depend on proper installation. The connection shall be performed by a qualified electrician. Remember, it is forbidden to connect the system to power supply until all elements are fully installed in accordance with the manufacturer’s instructions and checked.

Laying the heating strip by the use of any installation options starts from the system unit and ends also at the system unit!

Preparatory works for all installation options:

1. Draw a plan of the premises where the installation of the heating system is planned (indicate the stationary furniture on the plan, see point 3). Draw a layout of Salmerk system installation (system unit, power, heating strip and thermostat), taking into account the requirements stipulated in this manual. Keep the plan and layout together with the instruction, bill and warranty certificate!
