Installation Manual

MEGA-OHM INSULATION READINGS LOWER THAN SPEC
1. Rain or high humidity present
a. Dry wires at test point
b. Check for water ingress at junction boxes
c. Dry connections and re-test.
2. Physical damage to cold lead, splice, or heating product
a. Inspect installation area. Has any work been done in area by trade personnel? Is
there visible damage to the concrete, slab, or pavers?
b. Use troubleshooting kit and thermal camera to locate damage
c. Repair damaged area of cable
d. Replace damaged heating product
HEATING PRODUCT RESISTANCE LOWER THAN SPECIFICATION
1. Conductor shorted to ground somewhere in heating cable
a. Test for ohms across conductors to ground and compare to spec for that product
b. Use troubleshooting kit (from conductor to ground) and thermal camera to locate
fault
c. Repair damaged area of heating product
2. Both conductors shorted together somewhere in heating cable
a. Test for ohms across conductors and compare to spec for that product
b. Use troubleshooting kit (from conductor to conductor) and thermal camera to
locate fault
c. Repair damaged area of heating product

d. Use troubleshooting kit and camera to locate fault
e. Repair fault
2.Inspect breaker/reset
a. Verify proper operation
b. Verify proper amperage rating per install plan (re-calculate circuit load)
c. Verify proper mA rating of breaker (30 mA GFEP breaker required by code)
d. Replace defective breaker
e. Verify use of dual pole breakers for 208 & 240V heaters
3.Inspect all connections
a. Correct any incorrect wiring at all connections in the power feed
4.Inspect Junction Box/es
a. Install drains in boxes if required
b. Dry connections and re-connect
c. Replace any faulty junction boxes
