Controlling PW Pipe Freeze Protection Cable

The PW’s built-in thermostat means that no additional control device is required.

Notes on Selection and Installation

• Assuming a minimum ambient temperature of -15C 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 66C
• PF-L warning labels should be applied to the outside of the insulation.
