King Electrical Floor Heating Mat Installation Manual 5
STEP 1: Inspecting and testing the cable and floor sensor
1.1 Take the mat out of the box and inspect it for any physical damage.
1.2 Test the insulation and the resistance of the cable and record data in the CABLE TESTING LOG listed on page 6 of this
manual. This is test #1.
1.3 The cable and sensor must be tested and recorded a minimum of 4 times during the installation for the warranty to be
valid.
Insulation Test:
1.4 This test ensures that the insulation jacket of the cable is not damaged. A
low value on the meter indicates the cable
has been damaged and must be replaced. Follow the following steps:
A. Set the multi-meter to read ohms.
B. Connect the ground wire (braided un-insulated wire) to the black test lead of
the multi-meter and the red test lead to both the black and white wires of the
cold lead.
C. The meter should read “OPEN” or “OL”. If you get a different reading, the cable
is damaged, contact King Electric for support.
D. Record the readings on the cable tag and in the cable test log.
1.5 This test measures the resistance of the cable which verifies the
continuity (no breaks) and that the cable has the proper wattage rating.
A. Set the multi-meter to read ohms.
B. Connect the meter leads to the black and white old lead wires, DO NOT
connect the ground wire.
C. Compare the resistance reading to the value specified in the product
selection table, it should read 10%. If the reading
+-
is different, contact King Electrical for support.
D. Record the readings on the cable tag and in the cable test log.
