Before You Begin

Shut off the main water supply.

Observe all local plumbing and building codes.

Do not use this flow spout as a showerhead because it will cause excessive splashing and does not meet showerhead codes.

This flow spout is available in two orifice sizes: 3/4(2 cm) and 15/16(2.4 cm). The smaller orifice size is designed for a 5-10 gpm (19-38 lpm) flow rate, and Kohler K-400-K, K-401-K, or K-306-KS supply valves are recommended. The larger orifice size is designed for a 7-15 gpm (26-57 lpm) flow rate, and Kohler K-300-K or K-301-K supply valves are recommended.

NOTE: A flow rate lower than the flow rate listed on the specification sheet may disrupt the water flow.

The drip tray is an optional accessory available for the wall mount but not for the ceiling mount.

A water hammer arrestor is recommended in ceiling mounted applications using a high flow, deck mounted valve. Kohler recommends that a Sioux Chief 652-AD vacuum breaker arrester be located near the outlet side of the valve. Contact Sioux Chief at 1-800-821-3944 or www.siouxchief.com.

For ceiling mount applications, the height from the bottom of the bath to the spout should not exceed 9’ (2.7 m).

Before You Begin (cont.)

In applications where excessive air could enter the water supply, install an air separator.

When a deck mounted transfer valve (K-408-K or K-409-K) is used for a ceiling mount, install a check valve between the spout and the diverter.

Remove the mounting sleeve and cartridge before installing the spout body.

Kohler Co. reserves the right to make revisions in the design of products without notice, as specified in the Price Book.

1. Determine the Location

CAUTION: Risk of property damage. When employing a wall mount installation, install this spout at the end of the bathing fixture so the water stream projection stays within the bathing fixture.

There are three recommended installation configurations for the spout: 1) offset wall mount, 2) center wall mount, and 3) ceiling mount. The offset wall mount is highly recommended for the safety of the user.

Offset Installation

The spout assembly is placed 7(17.8 cm) from the center of the bathing fixture, away from the entry side of the fixture.

The offset configuration allows users to avoid the stream of water when entering or using the bathing fixture.

Center Installation

The spout assembly is positioned directly above and on the centerline of the bathing fixture.

This installation should only be used when the offset installation is not possible.

2. Ceiling Installation Layout

Install the spout in the ceiling over the bathing fixture at the shaded areas shown in the illustration.

Mount the spout so it is 9’ (2.7 m) or less from the bottom of the bathing fixture.

Locate the spout so the water stream contacts the flat bottom of the bathing fixture. Excess splashing will occur if the water stream contacts whirlpool jets or bathing fixture corners.

3. Install the Drip Tray Mounting Plate

NOTE: The drip tray is an optional accessory available for wall mount but not for ceiling mount.

NOTE: Install the 2x4’s so the drip tray is level or has a slight forward slope to ensure proper drainage.

Attach a 2x4 flush to the back of the wall stud to support the lower lip of the drip tray mounting plate. Position the 2x4 so it will be 2(5.1 cm) above the top of the bathing fixture.

Attach a second 2x4 so it is 5-5/8 (14.3 cm) above the first 2x4.

NOTE: When 2x6 wall studs are present, install the 2x4’s so they are supported 2(5.1 cm) from the back of the wall stud.

Attach the drip tray mounting plate to the 2x4’s using six drywall or #10x1screws. Make sure the mounting plate is centered under the spout’s location.

4. Install the Spout – Wall Installation

Install a 2x4 for spout support so it lays flush against the top support of the drip tray. If the drip tray is installed, the spout center must be 7-5/8 (19.4 cm) from the drip tray mounting studs. If the drip tray is not installed, the spout center must be 14-16 (35.6-40.6 cm) from the deck of the bathing fixture.

NOTE: When 2x6 wall studs are present, the front of the 2x4 must be flush with the front of the wall stud.

Install a 1x3 so it is 4(10.2 cm) above the 2x4 and inset 3/8(1 cm) from the back of the studs. The larger side of the 1x3 must face outward.

NOTE: When 2x6 wall studs are present, install the 1x3 so it is 2-3/8 (6 cm) from the back of the wall stud.

Place the spout assembly into position. Verify that the spout and drip tray mounting plate (if installed) are centered.

Remove the boot cap from the end of the intake pipe.

Remove the mounting sleeve and cartridge.
