IMPORTANT:

¾To ensure this VALVE is installed properly, you must read and follow

these guidelines.

¾The owner/user of this VALVE must keep this information for future

reference.

¾This VALVE and associated LAVATORY FAUCET (SOLD SEPARATELY)

must be installed by a professional licensed contractor and must be

onsite prior to rough-in. This allows the installer to visualize the

installation.

¾This VALVE is sold partially assembled but shown fully disassembled

for illustrative and service purposes only. Inspect the VALVE to

ensure you have all the parts required for proper installation.

¾Check countertop and sink measurements to assure the FAUCET

projects far enough into the sink.

¾Be sure your installation conforms to all federal, state, and local

codes. In the State of Massachusetts, all installations must comply

with the rules and regulations set forth within 248 CMR.

¾Use only a strap wrench or protected/smooth-jaw wrench on any

finished surface.

¾The use of certain plumber’s putty may stain stone or tile surfaces.

¾If further assistance is required, please contact Product Support at

ROUGH-IN AND VALVE PREPARATION:

¾Run well supported 1/2” hot and cold copper supply lines.

¾WARNING: The inlet supply spread of this product is NOT

ADJUSTABLE!

¾ROUGH-IN DEPTH: The rough-in depth is measured from the

centerline of the inlets to the surface of the finished wall and VARIES

depending on the TRIM (sold separately) being used.

¾Refer to the Installation Guidelines of the specific TRIM being used

for the MAXIMUM and MINIMUM rough-in depth dimensions.

¾ROUGH-IN HEIGHT: The rough-in height must allow for a MINIMUM

of 1-1/2” [38mm] air gap between the end of the SPOUT and

COUNTERTOP and also provide the HANDLE enough clearance to

fully open. This will vary depending on the TRIM being used and the

VALVE orientation.

INSTALLATION GUIDELINES

LAVATORY WALL MOUNTED VALVE

1. See the Installation Guidelines of the specific TRIM

(sold separately) being used for the MAX and MIN

rough-in depth dimensions.

NOTE: The rough-in depth is measured from the

centerline of the inlets to the surface of the finished

wall.

2. Pre-solder 1/2” COPPER PIPE to two 1/2” MALE

NPT x SWEAT ADAPTERS (not supplied) then

thread the ADAPTERS into the VALVE BODY.

NOTE: PIPES must be as long as possible to avoid

heating the VALVE and damaging the CARTRIDGE

when making final sweat connections.

FOR INTERNATIONAL INSTALLATIONS ONLY:

3. 1/2” NPT MALE x 1/2” FEMALE BSPP ADAPTERS

and RUBBER WASHERS are provided. Thread and

securely tighten the ADAPTERS into the VALVE

BODY.

4. With the VALVE in the desired orientation, run

1/2” copper supply lines to the appropriate height

and depth then connect to the VALVE using 1/2”

COUPLINGS (not supplied). Make sure the hot and

cold supplies are piped according to the VALVE

markings.

5. Verify the supplies are secure, level, and at the

proper spread of 1-3/16” [30mm] prior to making

final sweat connections. If necessary, utilize the

SUPPORT TABS and MOUNTING HOLES on the

VALVE to secure it to blocking or other support

material using appropriate SCREWS (not supplied).

6. Install a 1/2” NPT NIPPLE (not supplied) to

temporarily serve as a SPOUT then turn on the

water supplies and check for leaks.

† For INTERNATIONAL USE ONLY, a 1/2” NPT MALE x

1/2” FEMALE BSPP ADAPTER is provided.
