IMPORTANT – REGARDING INSTALLATION OF HEATING CABLES
Installation and installation material shall meet electrical standards and be installed by authorised personnel. Read this instruction sheet to be acquainted with the products.
Always use the same manufacturer on mounting kits as for the heating cable. Always follow the enclosed instructions at mounting of installation accessories.
When applications are carried out in explosive areas must junction boxes and other connecting material be consistent with Ex-class for the area.
Make sure that pipes, tanks etc, have been tested hydrostatic before installation of heating cable.
Always install the heating cable with position “five á clock” or seven on a pipe.
Observe! All heating cable applications require some form of thermal insulation to be able to supply heat to an object.
Do not install heating cable on equipment, which gets warmer than the maximum exposure temperature of the cable.
Do not install heating cables on a surface or on equipment containing potential caustic material without suitable outer sheath on the cable.
Do not be below the stated minimum bending radius for the heating cable.
At installations with more than one cable run or spiral winding of self-limiting cables where the distance between the cables will be lesser than 50mm, can interference between the cables influence the emitted output negatively in relation to the recorded value in the output table.
Always install heating cable on the outer radius on elbows to obtain sufficient power.
Never install the heating cable above expansion joints with giving the heating cable drift space, see installation example.
Never use binders or clamps which can damage the outer sheath to fix heating cables. (Exceptions can be done at mineral insulated cables).
Pumps and small vessels which are provided with heating cable and temperature control, shall the temperature transmitter be mounted at inlet. The cable on the pump/vessel should be physically separated from connecting piping cables in order to admit dismounting of pump/vessel.
Always cover the heating cable with aluminium tape/foil in order to improve dissipation of heat from the heating cable against the object and to avoid that the cable is pressed into the insulation material.
Longer stirring stick and parts of system with divergent percolation or dimensions should, if possible, be provided with separate control and heating length. Also consider that a “nude” couple on the conductor must be compensated with an extra heating cable.
Take into consideration the chimney effects and heat variations in media at heavy risings in a pipe system. To avoid negative efficiencies, a separate control and heating length is installed.
Take into consideration the stated lowest installation temperature at mounting in the data sheet.
If the application contain temperature sensitive pipe material (for example plastic) or if the application include temperature sensitive substances, take this into consideration when choosing cable and dimensioning. Contact the supplier for advice.
