testing
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 floor covering (i.e. while
the rolls are still exposed)
• After installation of the floor 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 significantly
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 subfloor is structurally sound, and is clean and dry.
It shall be noted that most wooden subfloor manufacturers (and also the wood
floor manufacturers) restrict the level of moisture content as well as Relative
Humidity for installing and maintaining sturdy subfloors. Strictly follow the wooden
floor/subfloor manufacturer guidelines for proper installation and maintenance of
wooden subfloors in order to avoid any horizontal or vertical movement of the
subfloor and consequential damage to your Environ™ Flex floor 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 floor before the
underlayment is installed. Take extra caution, if you use an automatic staple gun
to secure the cushion/underlayment to the subfloor, a badly installed staple could
protrude from the floor 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 fixtures, 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™.
