IMPORTANT:
¾ To ensure this product is installed properly, you
must read and follow these guidelines.
¾ The owner/user of this product must keep this
information for future reference.
¾ This product is intended to work with the Henry
Thermostatic with Shutoff Trim (HNTH30).
¾ This product and it's trim CANNOT be installed
horizontally. This product must be installed
vertically, as shown in the image to the left.
¾ This valve includes integrated service stops. Make
sure the tile guard is in place.
¾ This valve features anti-scald protection. The risk of
scalding exists until the installer had properly
calibrated/adjusted the temperature setting during
final trim installation.
¾ Valve body rough-in depth is measured from the
centerline of the inlets to the surface of the finished
wall and varies depending on the trim used. See
step #2.
¾ This product must be installed by a professional
licensed contractor.
¾ If soldering any connections, remove cartridge to
prevent damage to seals and internal assembly.
¾ The trim should be on-site prior to rough in and
allows the installer to visualize the installation.
¾ Inspect this product to assure you have all parts
shown that are required for proper installation.
¾ Check local building and plumbing codes to ensure
that your installation conforms to all applicable
requirements. In the State of Massachusetts, all
installations must comply with the rules and
regulations set forth within 248 CMR.
¾ Supply fittings are designed in accordance with
pressure and temperature ratings specified in ASME
A112.18.1/B125.
¾ If valve is going to remain unused for an extended
period of time (over 3 months), then the water to
the valve should be shut off (via service stops or
system control valve) and the volume control valves
should be opened to allow the water in the
thermostatic valve to evaporate. This is to keep the
cartridge from being exposed to stagnant or hard
water, which can cause the valve to malfunction.
