Notes on Selection and Installation
- Assuming a minimum ambient temperature of -15⁰C and 20mm thick insulation a PW heating cable can be installed in a straight line along pipes up to 50mm diameter
- Always select the shortest suitable cable from the PW range
- Where the cable is longer than the pipe it is protecting, wind the cable in a gentle, evenly spaced helix
- Secure the cable to the pipe at 300mm intervals using PF-T tape
- The entire installation including the thermostat should be covered with a maximum of 20mm thick flame retardant insulation
- Ensure that the thermostat is positioned at the coldest end of the pipe
- Plastic pipes should be wrapped in AL50 aluminium tape before installing the cable
- When used with pipes that may be empty, the cable should be covered in a layer of AL50 aluminium tape before the insulation is applied. A typical example would be when used with a condensing boiler
- PW cables must not be exposed to temperatures in excess of 66⁰C
- PF-L warning labels should be applied to the outside of the insulation.
