place. Then begin to feed the tubular heating cable sys-
tem into the pipe through the installed flexible coupler.
Note:
The pre-drilled dissolving ballpoint is designed
to reduce the friction of the Retro-DWS tubular heater
end-seal during installation. It also aids the passing of
the tubular heater product through and around fittings
located along length the pipe.
