Testing
Temperature sensor wire must be tested before and after installation and must
measure between 8k to 12k ohm for temperatures between 68-86 F (20-30C). This
measurement must be done with a digital ohm meter, set to the 20k range. Beware of
self-ranging meters and analog meters.
Each Environ™ Flex Roll is carefully tested before it is shipped from the factory, and
is packed to avoid damage during transit. However, damage does sometimes occur
in storage or transit, and sometimes during installation. We strongly recommend you
test the rolls:
• After unpacking the rolls but before you install them.
• After you have installed them but before you install the oor covering (i.e. while the
rolls are still exposed)
• After installation of the oor covering but before the thermostats are connected.
A simple test is a visual inspection to make sure there is no visible damage to the
heating element, and in particular to the cable component in the heater. We recommend
conducting an electrical test with an ohm meter to ensure that the ohms resistance is
what it should be. Ohms resistance can vary signicantly depending on the ambient
temperature and an allowance of -5% to +10% from the nominal value at 68ºF (20ºC)
is acceptable.
Pre-Installation Instructions
Ensure the suboor is structurally sound, and is clean and dry.
It shall be noted that most wooden suboor manufacturers (and also the wood oor
manufacturers) restrict the level of moisture content as well as Relative Humidity for
installing and maintaining sturdy suboors. Strictly follow the wooden oor/suboor
manufacturer guidelines for proper installation and maintenance of wooden suboors
in order to avoid any horizontal or vertical movement of the suboor and consequential
damage to your Environ™ Flex oor heating system.
To prevent damage to the rolls, special attention should be given to ensure that no nails,
screws, staple, or tacks are protruding from the sub oor before the underlayment is
installed. Take extra caution, if you use an automatic staple gun to secure the cushion/
underlayment to the suboor, a badly installed staple could protrude from the oor and
pierce and damage the Environ™ Flex Rolls.
Nails, screws, or staples should not be installed close to the rolls and power supply
cables. Permanent xtures, including built-in furniture, must NEVER be installed on
top of the rolls.
It is important to keep an accurate record of where the rolls are installed, to assist
you (and a future owner) to easily locate them; we suggest that you capture a
few photographs during the installation process, and ALWAYS save your custom
installation SmartPlan™.
