Resistance Testing Procedures - LATICRETE Floor HEAT Manual De Instalación

RESiSTAnCE TESTing PROCEDuRES

Follow the resistance documentation procedures outlined below and record
all Ohm Readings. It is essential that a copy of the final installation plan
(marked with any changes made in the layout of the system or its electrical
connections) is provided to the homeowner after LATICRETE Floor HEAT
products are installed.
LATICRETE Wire Eye™ electric wire fault indicator is recommended for use
during the installation of all LATICRETE Floor HEAT mat installations.
LATICRETE Wire Eye is a device which monitors continuity of
LATICRETE Floor HEAT mat(s) during the installation process and
notifies the installer if there is a break in the LATICRETE Floor HEAT mat. In
the case of lost continuity, an alarm sounds alerting installers to cease
installation. In the event LATICRETE Wire Eye sounds, stop and call
LATICRETE Technical Service Department at 1.800.243.4788 ext. 235
before continuing. For further instructions regarding LATICRETE Wire Eye
please see detailed instructions included in product packaging.
1. Verify that materials shipped match materials ordered before
unwrapping mats.
2. Measure and record the initial resistance of each element.
A. 120 Volts: Test between the hot (Yellow or Black) and neutral
(White).
B. 240 Volts: Test between the Line 1 (Red) and the Line 2 (Black).
Compare the reading(s) with the Theoretical Ohm Reading(s) provided on
the chart in this manual on page 6. If there is more than a +/-10%
difference between the Actual Reading taken and the Theoretical
Reading, stop and call our Technical Service Department at
1.800.243.4788 ext. 235 before continuing with the installation.
Compare each Ohm reading taken in steps 3, 5, 7, and 9 with the initial
Ohm readings taken in Step 2. If there is a significant change at any
point during or after the installation, stop and call our Technical Service
Deptartment.
3. Measure and record the resistance of each element (See Step 2) again
after customizing the mat(s).
4. Verify that there are no shorts in the LATICRETE Floor HEAT mat(s)
by checking the resistance between the Hot (Line) and Ground.
There should not be continuity. If there is continuity, stop and call
our Technical Service Department at 1.800.243.4788 ext. 235 before
continuing with the installation.
A. 120 Volt product: Test between the hot (Yellow or Black) and Ground
(Green) and also between the neutral (White) and Ground (Green).
B. 240 Volt product: Test between Line 1 (Red) and Ground (Green)
and also between the Line 2 (Black) and Ground (Green).
5. Measure the resistance of each element (See Step 2) again after the
LATICRETE Floor HEAT mat has been secured in place.
6. Repeat Step 4.
7. Measure and record the resistance of each element (See Step 2) again
after the LATICRETE Floor HEAT mat(s) is/are embedded in the thin-set mortar
or self-leveling underlayment.
8. Repeat Step 4.
9. Measure the resistance of each element (See Step 2) again after
the flooring has been installed. Record the final resistance on the
Installation Plan.
10. Repeat Step 4.
11. Attach the White Output Label(s) to the end of the corresponding
lead wire(s).
12. Place each Silver Output Sticker in an easily accessible place on
the Circuit Breaker Box to label the circuit(s) with the electrical description
of each mat.

Resistance is measured in units known as Ohms. The Digital Ohmmeter
or Multimeter used must have a scale capable of reading resistance in
the range of 0-200 Ohms.
All electrical connections must be made by a licensed electrician and
