Instructions for installation
FrostGuard is supplied with 2 m of power cable and a plug for temporary
installation. The cable is non replaceable and the entire heating cable must
be discarded if it is damaged. The connection plug of the UK FrostGuard
product should be made FrostGuard plug.
CAUTION: Make sure that the heating cable is not covered by material with heat
use, contact your electrical contractors for thermostat.
Use a 30-mA GLCB or RCD. nVent, international and local electrical codes, and
standards all require the use of a ground-fault equipment protection device on
each heating
cable circuit. Arcing may not be stopped by conventional circuit breakers
which could result in a fire hazard.
De-energise all electrical circuits before installation or servicing.
The presence of the trace heater shall be made evident by the posting of
caution signs at frequent intervals along the circuit.
External installation
1a. Tape the heating cable to the underside of the pipe. Use age-resistant
tape, e.g. electrical tape.
2a. Insulate the pipe. Select the insulation thickness according to the table.
3a. Connect to a wall socket.
Internal installation
1b. Fit the Y-piece to the pipe. Thread the R20-connector onto the heating
cable. Use a lubricant, such as washing up liquid, to facilitate application
of the rubber packing. Insert the heating cable into the Y-piece. The splice
between the heating cable and cold cable must not be inserted in the pipe.
2b. Fully tighten the R20 connector.
3b. Insulate the pipe. Select the insulation thickness according to the table.
