1. BEFORE YOU BEGIN

HOW TO USE THESE INSTRUCTIONS

Please read these instructions carefully to familiarize yourself with the required tools, materials, and installation sequences. Follow the sections that pertain to your particular installation. This will help you avoid costly mistakes. In addition to proper installation, read all operating and safety instructions.

PRODUCT REQUIREMENTS

 For roughing-in dimensions, see Fig. #1.  Ensure that any holes drilled in the deck are not

oversized. The spout requires adequate base material strength. Spout and valve washers must contact a maximum amount of deck surface. Spout hole = 1” (2.5cm) maximum; and valve holes = 1-1/2” (3.8cm) maximum.

 Finish deck material must fit closely to the

diameters of the plaster guards, especially the spout plaster guard.

 If holes are drilled in the sheet deck material before

placement on the deck, they must match the plaster guard diameters.

 Plaster guard diameters are approximately 1-5/8”

(4.1cm) for the valve, and 13/16” (2.1cm) for the spout.

 Installer-supplied copper tubing is to be 5/8” O.D.

(1/2” nominal).

 Provide an access panel to the valves from the

underside of the deck.

 Install water hammer arrestors in the supply lines

near the valves.

All information in these instructions is based on the latest product information available at the time of publication. Kohler Co. reserves the right to make changes in product characteristics, packaging, or availability at any time without notice.

INST ALLER INFORMA TION

 Observe all local plumbing and building codes.  Products purchased separately may influence

valve placement and alignment.

 Spout will require that the spout supply tube be cut

to the proper length.

 Instructions are given for installation with 8”

(20.3cm) centers. For installations wider than 8” (20.3cm) centers, adjust all roughing-in dimensions and copper tubing lengths accordingly .

 These instructions cover two methods of

installation: installation on finished deck or rim; and installation on rough (unfinished) deck (to be covered later with tile or other finish material).

 Leave the protective sleeve on the spout supply

tube until the spout is installed. This is an O-ring sealing surface, which may be damaged if unprotected.

2. INSTALLATION ON FINISHED DECK OR RIM

NOTE: For installation on rough (unfinished) deck,

proceed to Section 3.

Preparation: For installations with 8” (20.3cm) centers using copper tubing (1/2” nominal, 5/8” O.D.), cut the tubing to the lengths as follows:

2 pieces: 2-7/8” (7.3cm) long 1 piece: 2-3/8” (6cm) long (for spout supply) For non-8” (20.3cm) center installations, adjust the

tubing lengths as necessary.

NOTE: Leave the protective sleeve on the spout supply tube until the spout is installed. This is an O-ring sealing surface, which may be damaged if unprotected.

Install Spout Supply Tube: Slide a brass washer from the bottom of the spout supply tube over the threads until the washer reaches the supply tube shoulder.

Insert the spout supply tube through the mounting hole from the top of the deck/rim. Ensure that the flat portion of the washer faces forward. The supply tube will be suspended by the washer.

Slide a brass washer onto the spout supply tube from the bottom, and thread on the mounting nut. Tighten the nut.

NOTE: Do not use the supplied wood screws for installation on finished deck or rim.

Install Valve Bodies: Thread one mounting nut, flange side up, onto each valve body.

NOTE: Rims less than 1/4” (6mm) thick require two rubber washers in the following step; other installations require only one rubber washer.

Slide one fiber washer, followed by one or two rubber washers, onto each valve body.

Insert the 2-7/8” (7.3cm) long copper tubes between the valve bodies and the 1/2” tee. Then insert the 2-3/8” (6cm) long copper tube into the top of the tee.

NOTE: Orient the valve body marked “COLD” so it is on the right when facing the front of the faucet.

Insert the valve bodies through the mounting holes from the bottom of the deck. Mate the copper tube from the tee with the spout supply tube. Hold in place.

Set a collar, with the flange side up, onto each valve body . Thread down to at least 1” (2.5cm) from the top thread on the valve body.

Set Valve Body Height: Use one of the following two formulas to calculate the valve body clearance required for the finish material at your site.

Add the tile thickness to 1-1/4” (3.2cm) (distance required from the finished deck to the top of the valve threads), if the tile is less than 1” (2.5cm) thick.

Example #1: Tile thickness 3/4” (2cm) + 1-1/4” (3.2cm)

= 2” (5cm) clearance.

If the tile thickness is between 1” (2.5cm) and 1-1/4” (3.2cm), add only 1” (2.5cm) to the 1-1/4” (3.2cm) distance.

1012557-2-A

Supply Tube Connection: Measure the distance from the bottom of the spout supply tube to the top of the tee.

Add 1” (2.5cm) to this measurement, and cut a piece of 1/2” nominal (5/8” O.D.) copper tubing to fit into the supply tube and tee port.

Back off the threaded collars as far as possible without removing them. Pivot the valve bodies enough to remove the tee and two pieces of tubing. If the valve body holes are smaller than recommended, it may be necessary to remove the entire valve body assembly.

Install the tubing into the tee. Mate the copper tube from the tee with the spout supply tube. Pivot the valve bodies onto the two pieces of copper tubing.

DO NOT solder at this time.

Reset Valve Body Height: Adjust the threaded collars until the dimension from the top of the valve threads to the top of the rough deck surface equals the clearance requirement you calculated in Fig. #9.
