IMPORTANT
To ensure this product is installed properly, you
must read and follow these guidelines.
The owner/user of the valve must keep this
information for future reference.
The risk of scalding exists until the installer has
properly calibrated the temperature setting.
Valve body rough-in depth is 3 1
8
"-4" from the
centerline of the inlets to the face of the finished
wall.
This thermostatic valve only mixes hot and cold
water and does not have volume control or shut
off capability. Wall valves (provided separately)
control on/off/volume and must be installed for
each fitting that will have water flowing to it.
This product must be installed by a professional
contractor.
If soldering any connections, remove cartridge to
prevent damage to seals.
This valve should be on-site prior to rough in and
allows the installer to visualize the installation.
Inspect this product to assure you have all parts
required for proper installation.
Install accessible hot and cold service stop valves to
facilitate servicing.
ROUGH IN:
1. Make sure the valve body (12) is positioned
according to valve markings so the inlets are situated
with hot piped on the left and cold piped on the

.25 THERMOSTATIC SHOWER VALVE TRIM (PTSV58 & GUSV78R) All dimensions are
based on original specification and are subject to change and variation. Please consult your Design Associate
for current specifications.
Check incoming water pressure; ideal operating
pressure is 40-60 psi. Maximum pressure is 80 psi.
per most plumbing codes.
Check local building and plumbing codes to ensure
that your installation conforms to all applicable
requirements.
Supply fittings are designed in accordance with
pressure and temperature ratings specified in
ASME A112.18.1/B125 and ASSE 1016.
FLUSH OUT THE SYSTEM:
5. The supply lines must be flushed out to prevent
clogging of the filter screens. Failure to flush the lines
will permanently damage the cartridge and void the
warranty.
Refer to the specification and assembly drawings
attached. Valves are sold partially assembled but
shown fully disassembled for illustrative and service
purposes only.
