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. Additional add on kits and fittings may be required for sizes other than 4-inch. Retro-DWS is also suitable for 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 to fit a 4-inch pipe (3-inch kit optional add on) 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 standard components.

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.

WARNING

Important Safety Instructions and Rules for safe
Installation and Operation

FIRE AND SHOCK HAZARD. This component is an electrical device which must be installed properly. Read and follow these rules and instructions carefully. Failure to follow them could result in serious bodily injury and/or property damage.

WHEN PERFORMING WORK OR REPAIRS ON YOUR
WATER SYSTEM BE SURE TO UNPLUG YOUR HEAT-LINE
SYSTEM FROM THE POWER SUPPLY.

• Check your local building, plumbing and electrical codes before installing. You must comply with their rules.
• Do not force the Retro-DWS into the pipe to the point where the pipe creases and bends
• Do not install the Retro-DWS interface connection in a manner which would render it non-serviceable.
• Retro-DWS meets cCSAus codes for use in Canada and the United States.
• Before installing this product have the electrical outlet checked by an electrician to make sure it is properly installed and grounded in accordance with your local Electrical Code.
• Before installing or servicing your Retro-DWS BE CERTAIN that the power source is disconnected.
• Do not use extension cords.
• This product is designed to keep drains from freezing in serious climate conditions. The Retro-DWS tube may obstruct certain materials, especially solids in the drains so a service schedule for proper maintenance is recommended.
• The use of this product is at the sole discretion of the user. Heat-Line will not be liable for obstructions or blockages that may occur in some situations.

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 temperatures, 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 System Connection

Electrical Connection for GFC (Ground Fault Plug-in) Models

A. Unpack the Retro-DWS system plug from its protective package.
B. Plug into your dedicated outlet. 120V 5-15R outlet for 120V systems or 240V 6-15R outlet for 240V systems.
C. Push reset button on the cord set ground fault device until light comes 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 go OFF. This indicates that the electrical circuit is intact and fully protected.
E. Push reset button again and light will come 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.
If at any time your Retro-DWS system fails to work call your local electrician or Heat‑Line for assistance at 1-800-584-4944.

Unplug when not in use.

Electrical Connection for CS (Cord-Set) Models into Junction Box
Note: The “CS” version is designed to be installed by a qualified electrician and must be inspected by the governing electrical authority following completion of installation.
A. Ensure the Retro-DWS system will be operated on a dedicated ground fault protected circuit with over-current protection appropriate for the circuit conductor size and heating cable length.
B. Confirm power is disconnected at the power supply prior to proceeding.
C. Remove approved junction box cover.
D. Route the Retro-DWS cord-set wires into box with the supplied strain relief fitting.
E. Connect appropriate wires together using approved wire nuts.
Match wires white to white, black to black, and green to green. In the case of a metal junction box/enclosure, match green to ground screw and confirm screw is tight and secured afterward.

F. Double check that the wires have been connected correctly and tight.
G. Install junction box cover.
H. Establish power to the circuit and test/reset the ground fault device for proper operation.
