Paint the subfloor with Warmup
®
primer*.
Before applying the primer ensure that the floor
surface is smooth, dry and free from dust or grease.
If necessary, an appropriate smoothing compound
should be applied and allowed to cure.
If the cable is being fitted to a solid floor it is
essential that the concrete slab has been allowed to
cure before the primer is applied. This can take 8
weeks or more. If tiling on existing ceramic or quarry
floor tiles, clean the floor with an appropriate floor-
cleaning compound.
Do not
apply the green Warmup® primer; go to
installation step 2.
If tiling on water proof/resistant surface (ie
Hardibacker)
do not
apply the green Warmup®
primer; go to installation step 2.
Using the roller supplied, apply the primer evenly to
the entire surface to be heated.
The primer must be allowed to dry for a minimum
of 3 hours.
The light green color of the primer will change to
a darker green once dry and will be slightly sticky.
Good ventilation must be provided which, along with
a higher ambient air temperature, will accelerate the
drying process.
Avoid traffic over the subfloor once the primer has
been applied.
IMPORTANT! – Test the cable
Strip the ends of the cold lead wire and test the black &
white cables to ensure the cable is working properly. Using
a digital ohmmeter or multi-meter, check the resistance of
the heating cable and continuity of the
protective ground braid. Please note that analog meters
with a moving needle are not sufficiently accurate for
testing the Warmup cable.
Set your Ohm meter to measure resistance in 0 – 200
Ohms. Acceptable readings of these ohms resistance
measurements
There should NOT be any continuity between the ground
wire and either of the white neutral wire or the black live
wire. Any continuity indicates there is a short in the circuit.
*If the cable is being fitted to a wooden floor, the floor should be boarded over with tile
backer board or 3/4” plywood or Warmup® Insulation Board.
