6. Check the heating cable and supply line for damage.
7. Only one cable end is heated. The heated cable is the cable which comes out of the top side of the
drinking bowl. The cable which comes out of the rear of the bowl is not heated.
The heated end can be drawn out of the upper feed-through and routed downwards, if e.g. the drinking bowl is
connected from underneath. The hole can be closed using the plug (black plug included in the delivery).
Important: The last 30 cm of the heating cable – towards the connection end – are not heated.
8. Route only the heated end along the pipe, and fix it in place using aluminium adhesive tape. Comply with
safety instructions.
- Route the cables so that they are out of the reach of animals.
- Cable ends (at plugs or junction boxes) must be easily accessible for repair and maintenance work.
9. Attach insulation. The insulation must be no thicker than 13 mm. Excessive insulation of the heating cable
leads to overheating.
10. The insulation must be protected with an additional waterproof sheath which is laid helically over the
insulation to prevent moisture ingress.
11. Route the supply line (unheated end) along the insulation, and also fix it in place using aluminium adhesive tape.
12. Connect the supply cable to the power supply in a single run.
