IMPORTANT:
¾To ensure this product is installed properly, you
must read and follow these guidelines.
¾The owner/user of this product must keep this
information for future reference.
¾This valve includes integrated service stops. Make
sure the tile guard is in place.
¾This valve features anti-scald protection. The risk of
scalding exists until the installer had properly
calibrated/adjusted the temperature setting during
final trim installation.
¾This product must be installed by a professional
licensed contractor.
¾Check 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.
¾Supply fittings are designed in accordance with
pressure and temperature ratings specified in ASME
A112.18.1/B125.
¾DO NOT APPLY DIRECT HEAT TO THE VALVE. Pre-
solder any connections to prevent damage to the
cartridge and service stop seals.
¾The trim should be on-site prior to rough in and
allows the installer to visualize the installation.
¾This thermostatic valve only mixes hot and cold
water and does not have volume control or shut off
capability. A diverter or wall valves (SOLD
SEPARATELY) control on/off/volume and must be
installed for each fitting that will have water flowing
to it. This valve cannot be used with a diverting tub
spout.
¾Insure that the hot and cold supply lines are
connected to the valve according to the markings
on the valve body: NO INVERSE CARTRIDGE IS
AVAILABLE.
¾Inspect this product to assure you have all parts
shown that are required for proper installation.
¾Check incoming water pressure.
¾If 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.
¾It is recommended to flush the supply lines prior to
valve installation.

2. Make sure the valve body is positioned according to
valve markings so the inlets are situated with hot
piped on the left and cold piped on the right. Turn
the service stops to the right to close and to the left
to open. See Figure - 02.
