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.
I. Test the GFCI at the breaker before each season and monthly
while in use.
Your Retro-DWS system 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.
