Instructions / Assembly

DO NOT SUPPLY THE SYSTEM
WITH ELECTRIC CURRENT
All testing is done with a digital Ohmmeter. Supplying the system
with a 120 volt electric current before the installation is complete
is not needed to test the system.
Taking the Ohm Readings
The electrical resistance of the Heating Roll(s) must be checked
before you start, and monitored throughout the installation
process to ensure there has been no damage causing shorts or
breaks. We recommend at least three readings be taken:
1. Before starting installation.
2. After securing the Heating Roll(s) in place on the suboor.
3. After installing the ooring surface above the Heating Roll(s).
Record the Ohm Readings
The Value on the UL label should be within +/- 15% variance of
the original measurement indicated on the label. The electrician
should carefully mark the initial Ohm reading taken onto the
warranty card. Should the initial Ohm reading be outside the 15%
+/- variance, refer to the electrical trouble shooting section on
Page 9, or call Technical Support at (800) 875-5285.
Go by the Numbers
The Ohm resistance should be measured from the inner core
of the yellow (120V) to the inner core of the Black lead wire at
the other end. Make sure that the probe of the Ohmmeter does
not touch the tinned sheath wire at either end. Even your body’s
electrical resistance can affect the reading if you touch the meter
poles. Do not hold the wires onto the probes with your ngers. A
digital meter is easier to use and strongly recommended. It is wise
to verify that the batteries of the Ohmmeter are good. Set your
Ohmmeter to measure resistance in the range of 0 to 200 Ohms.
Three (3) Ohm Readings should be taken for each roll of
WarmlyYours TempZone at each stage of the installation and
recorded in the table below.
1) Core to Core - This is the reading between the two inner
conductors on the lead wires.
2) Core to Sheath Yellow Lead - This is the reading between the
inner core and the outer ground sheath on the lead wire. This
reading should be innity.
3) Core to Sheath Black Lead - This is the reading between the
inner core and the outer ground sheath on the lead wire at the
nish point of the roll. This reading should be innity.
After the installation, if necessary, the position of a break can be
found with a troubleshooting kit and thermal camera. Repair kits
and guidance are available from the WarmlyYours support line.
