Heatline Retro-DWS Series User manual

Patented
Kit Description
Retro-DWS is a tubular self-regulating heating system designed for use in
4-inch and 3-inch non-pressurized sewage and waste water drain lines, as well
as other large diameter non-pressurized pipes and storm drains. The core tube
is constructed of HDPE (high density polyethylene) and will push inside most
pipes for long distances. They can also be drawn in with a fish tape.
Retro-DWS utilizes a conductive polymer tubular heater technology which
provides a barrier from the fluids while providing extremely efficient freeze
protection. Retro-DWS can be used as a system to prevent freezing or as a
precautionary system. If the drain waste or sewer freezes, the system can be
energized to begin the thawing process.
Retro-DWS is supplied with all of the necessary fittings for 4-inch or 3-inch
pipes at a clean out or other entry point. The Retro-DWS can be easily adapted
to fit larger pipe diameters if required by using readily available, industry stan-
dard components.
Typical Retro-DWS-GFC supplied with a 4 foot electrical cold lead.
Available with Ground-Fault Protection (GFCI) or Cord-Set (CS) both in
120 volt and 240 volt.
For installation of Retro-DWS into other applications refer to Retro-DWS
Other Methods document.

• Push the pre-drilled dissolving ballpoint onto the
end-seal of the tubular heater making sure it is
firmly in place. Then begin to feed the tubular heat-
ing cable system 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.

Control Devices and Insulation Installation
Control devices are not required to operate the heating
cable system. They can be added for energy efficiency.
Thermostats are used to duty cycle the system in an on/
off operation saving power consumption and maintain a
certain pipe temperature. A sensor lead must be placed on
the coldest section of pipe.
Timers are used to duty cycle the system in an on/off
operation based on preset time intervals to save on power
consumption.
Insulation is recommended for all new pipe installations,
even where the pipe is to be buried.
For existing pipe applications, insulation is only required
where the pipe is exposed to ambient outdoor tempera-
tures, and/or where the pipe is above the ground. Insulation
aids in heat retention making the heating cable more energy
efficient and providing cold weather reliability.

Electrical Installation and Testing
TEST
RESET
Pilot light
(120V 15A example shown)
A. Unpack the Retro-DWS system plug from its protective package.
B. Plug into your dedicated outlet. 120V outlet (5-15R) for 120V sys-
tems or 240V outlet (6-15R) for 240V systems.
C. Push RESET button on the cord set ground fault device until light
turns ON. If light does not illuminate check power to outlet. Do
not remove or tamper with the cord set. If used with a thermostat
it may be necessary to bypass the thermostat control and plug
directly into receptacle to perform test.
D. Push TEST button and light will turn OFF. This indicates that the
electrical circuit is intact and fully protected.
E. Push RESET button again and light will turn ON. This indicates that
your Retro-DWS is working.
F. Follow this test procedure before each season and monthly while in use.
Your Retro-DWS is now fully functional.
