IMPORTANT: Do NOT turn on the WarmlyYours TempZone™ Floor Heating Cable (Twin) system until after the
thinset or self-leveling underlayment (SLU) has fully cured. Doing so will result in damage to the system
and cause the thinset or SLU to become brittle. Failure of the thinset or SLU may cause damage to the
embedded cable. This type of damage is not covered by the WarmlyYours warranty.
