Installation And Commissioning - Kerbl 223582 Manual De Instrucciones

3. Installation and commissioning

Prepare the pipe and heating cable:
1. ensure that the area around the pipeline is easily accessible and there are no sharp edges or flammable
materials.
Danger!
• Fire hazard! To prevent fires, the heating cable should be kept at least 13 mm away from all flammable
materials.
2. If the heating cable is to be used to keep a plastic water pipe free from frost, the plastic water pipe must
be completely wrapped with an aluminium adhesive tape (Kerbl item no.: 222809).
The aluminium adhesive tape improves heat transfer, evenly distributes the heat around the pipe and
prevents localised heating, as aluminium is a better heat conductor than plastic. (Fig. 5)
Danger!
• The heating cable must only be used on temperature resistant water pipes approved for hot water.
• Never install the heating cable on a plastic pipe unless it is ensured that the pipe is always filled with
water.
3. Electrically earth all installation metal parts.
Danger!
• For safety reasons, metal pipes, guttering, protective tubes and sheathing must be earthed before
installation. Ensure every metal part is earthed before beginning installation. The entire system must be
checked for consistency and any necessary additional earthing connection must be created.
• Do not install the same heating cable simultaneously on different pipes. This could cause the heating
cable to overheat and lead to fire or electric shock.
4. Allow the heating cable to warm up to room temperature before beginning the installation.
Danger!
• The heating cable must not be installed at outside temperatures of < +5 °C.
5. The heating cable's continuity, resistance and insulation resistance must be checked before beginning
installation and also after installation, but always before connecting the power cord.
Important! The resistance value before and after installation must match the value on the product label.
A tolerance of + -5 % to +10 % is allowed. The insulation resistance must be more than 10 MOhm. (See:
Table 1.)
