Danfoss TX-FH Installation guide
IMPORTANT!
DO NOT CROSS OR CUT THE HEATING CABLE.
REMEMBER TO MEASURE, VERIFY AND
RECORD THE RESISTANCE. USE A MEGGER TO
TEST THE RESISTANCE TO GROUND.

Danfoss TX-FH Electric Floor Heating System
Danfoss TX-FH Electric Floor Heating System
Danfoss TX-FH cables are a thick floor heating solution. Thick cables have a larger diameter
than the Danfoss LX floor heating cables, allowing them to be lower in COST, higher in HEAT
OUTPUT, and more DURABLE. They are installed in mud beds below the flooring materials
and are most often used in new construction where overall material cost is a primary
concern.
Benefits of the TX-FH thermal storage are numerous over other heating methods, and
include:
· Easy and flexible installation combined with a single point connection.
· Extremely durable
· Single point connection
· Twin conductor cable
· Emits zero EMF (Electromagnetic fields)
· Safety approved for wet locations
· Reduced dust and allergens
· Silent, safe, and efficient operation
· Reclaimed interior floor space (no furnace/boiler required)
· Genuine ten year non-prorated warranty
CAUTION!
It is important that this equipment is installed only by qualified electricians who are
familiar with the proper sizing, installation, construction and operation of floor warming
system and the hazards involved. The heating cable is designed for under floor heating
purposes only.

MONITOR YOUR INSTALLATION!
USE THE LITTLE BUZZER CONTINUITY
ALARM (PART#088L0028)
Little Buzzer
Using a digital Ohmmeter, t black and white .
Compare the measured resistance to the resistance listed on the product label (on the r lead).
he resistance should be measured between the conductors
powe
Also, measure the resistance between the black and green (ground) wires, and between the white and green
(ground) wires to test the insulation resistance. Both should should have infinite resistance.
Danfoss recommends using for this test with a voltage setting of up to V.
a megaohmmeter 2500
If available,
Record the resistance on your warranty card. Documenting the resistance at each stage of the installation is
required for warranty purposes. If the resistances do not match the expected values, the cable may need to
be damaged and need repair. Contact your Danfoss representative for a repair kit (part # 088L0010)
While not required, you may also want to measure the resistance of the floor sensor. It should be
approximately 12kΩ at room temperature.
