Mandatory Resistance Testing Requirements

For the extended 25 year limited warranty to apply, you must perform the testsin this section, and follow all instructions noted in the Limited Warranty.

You must perform the Insulation Resistance Test, the Heating Cable Resistance Test,and the Sensor Resistance Test during the installation process.

Insulation Resistance Test

This test ensures that the insulating jackets of the cable are not damaged. A low valueindicates the cable has been damaged and must be replaced.

1. Connect the ground wire to the blacklead and both power wires to the redlead of the multimeter.

2. Make sure the meter reads “open” or“OL.” If you get a different reading,contact WarmAll™at 1-866-994-4664.

3. Record these readings on thewarranty card.

Heating Cable Resistance Test

This test measures the resistance of the Cable and is used to determine circuitintegrity.

1. Set your multimeter to the 200 or2000 ohm range.

2. Connect the multimeter leads to theblack and white cold lead wires.

3. Compare this resistance reading tothe resistance specified in theProduct Selection “Table 1 or Table2”. The value should be within ±10%.If you get a different reading, contactWarmAll™ at 1-866-994-4664.

4. Record these readings on thewarranty card.

Sensor Resistance Test

This test measures the resistance of the floor sensor and is used to verify the sensorintegrity.

1. Set your multimeter to the 200K ohmrange.

2. Connect the mutimeter leads to thered and green lead wires.

3. Make sure the meter reads between9-25K ohms. If you get a differentreading, contact WarmAll™

4. Record these readings on thewarranty card.
