SECTION 4. Inspection and Testing
A visual and electrical check must be performed on the heating mats prior to activation.
Visual Inspection
Also perform a visual check to look for any signs of damage to the mat or electrical leads that may
have occurred during installation. When visually checking the mats, look for any signs of damage,
wear, or scratching that might have occurred during installation. If any portion of a mat appears dam-
aged, replace the entire mat. If damage is found, call the technical hotline at 888-WARM-PAD or email
[email protected] for advice and/or replacement assistance.
Continuity/Resistance Check
Following installation, a second resistance check across the supply leads of each mat using a digital ohm meter
must be made to detect any short or open circuits that may have resulted from the installation process.
If the resistance check is the same as the original reading shown on the mat label, the mat is installed properly
and no further testing is required.
If the resistance readings are not within ±5% of the indicated value on the mat then call 888-WARM-PAD. If the
resistance is ZERO: This indicates a short circuit. Check the path that the wiring is taking and make sure that no
wires are pierced or otherwise damaged. Mats with damaged non heating leads must be replaced.
Installation & Owner’s Guide 13
NOTES:
Record the resistance measurements of each mat after installation. These measurements should be
compared to the readings recorded on the product label for each mat to confirm a successful installation.
These measurements are required for warranty registration.
If a mat fails the resistance check, it must be retested after any corrective actions.
