Installation of the Trace Heater Cable
The Trace Heater cable is pre-threaded into the Clear PVC Tubing. Ensure that the Ferrule end protrudes by at least 10mm. The entire assembly needs to b
e threaded through the condensate pipe such that the condensate will run down the centre of the clear plastic tube and will remain in close contact with the heating element.
1. Cut the Condensate Drain Pipe at a convenient place (Fig.1) and thread the Trace Heater/PVC tube (Ferrule end first) into the Condensate Drain Pipe (Fig.2). If this proves too difficult, this can be overcome by dis-assembling the Condensate Drain Pipe, threading the heater/tube through and then re-assembling.
2. The heating cable should run the full length of the condensate pipe as shown in Fig.3.
3. If the Condensate Drain Pipe is shorter than 3 metres,cut the Trace Heater Cable/PVC Tubing to reduce the length as appropriate. Extra care must be taken when shortening the trace heater cable as the heating elements are both few and delicate. These will need to be folded to ensure good electrical contact (Fig.4). If you have shortened the Trace Heater Cable, carefully pare back the PTFE outer sheath to reveal the shielding. You will need to prepare a connection using the shielding and then prepare a connection of the inner core (See Fig.4). Crimp supplied ferrules over the exposed conductors. Remember to leave enough Trace Heater Cable to extend through the T Piece and to allow you to connect to the connector box. Do NOT attempt to shorten the heating cable from the sealed end. Make sure that the trace heating cable is NOT shorter than 1 metre in length.
4. Attach the Clear PVC Tube to the adaptor so that all the condensate will drain through the PVC Pipe (see Fig.5).
5. Slide the Clear PVC tube and Adaptor back into the Condensate pipe as shown(see Fig.6)
6. Decide how the T Piece will enable the Trace Heater to enter the Condensate Pipe ie Straight through or at 90 degrees (see fig.7).
7. Pass the Trace Heater Cable through the selected opening in the T Piece and fit the T Piece to the Condensate Drain Pipe and fix using the appropriate adhesive (see Fig.8a and b)
8. Thread the Trace Heater Cable through the bung (from the narrow end) and push the bung into the T piece to seal the pipe. You may require a sealant at the cable exit (see Fig.9a).
9. Connect the two wires from the Trace Heater to the connector block. Blue to inner core, Brown to shielding. The twin core electrical cable is used to connect the Trace Heater Cable to the main Frost-Sentry unit. This prevents the Frost Sentry from becoming too warm when the unit is in operation (see Fig.10).
10. Plug the other end into the indicated connection on the Frost-Sentry unit (see Fig.11).
