Important Notice!
HeatLink products are intended for installation by a licensed plumbing contractor. It is the sole
responsibility of the installer to verify that the product meets local codes and standards.
Like most plastic material, crosslinked polyethylene is subject to ultraviolet (UV) deterioration
and must not be continuously exposed to direct or indirect sunlight, or fluorescent lights,
beyond the stated limits. Storage outside is not recommended.
To ensure system integrity and warranty remain intact do not expose PEX or fittings to
unknown/untested chemicals.
