Important Information

NOTE: This product is designed for installation with the electrical and water supplies located through either the wall or the ﬂoor.

Grounding Instructions

•

This product should be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This product is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded.

WARNING: Risk of electric shock. Improper use of the grounding plug can result in a risk of electric shock.

•

If repair or replacement of the cord or plug is necessary, do not connect the grounding wire to either ﬂat blade terminal. The wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire.

•

Check with a qualiﬁed electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the product is properly grounded.

•

This product is factory equipped with a speciﬁc electric cord and plug to permit connection to a proper electric circuit. Make sure that the product is connected to an outlet having the same conﬁguration as the plug. No adapter should be used with this product. Do not modify the plug provided — if it will not ﬁt the outlet, have the proper outlet installed by a qualiﬁed electrician. If the product must be reconnected for use on a different type of electric circuit, the connection should be made by qualiﬁed service personnel.

1. Install the Remote Dock

NOTE: The docking station comes with a 15’ (4.6 m) cord. Locate the docking station to allow the docking cord to reach the toilet.

Unpack the box containing the remote control components. Remove the remote control from the dock and set aside. Remove the small screw on the bottom of the docking station. Carefully remove the cover plate by gently prying the sides of the cover plate out until they

disconnect from the dock. Carefully disconnect the cover plate plug. Tape the screw to the cover plate and set it aside.

NOTE: When the docking station cord is routed externally through the wall, it may be easier to use the back cord opening. When the cord is routed externally along the face of the wall, use the bottom cord opening.

For installations using the back cord opening, route the power cord through the back cord opening. For installations using the bottom cord opening, route the power cord through the bottom cord

opening. Position the docking station in the installation position and mark the screw locations using the dock

as a template. Drill appropriate size mounting holes at the screw mounting locations. The size of the hole will

depend on the need for wall anchors, wall material, and installation requirements. Loosen each of the ﬁve small screws located where the wires will be connected. Run the power cord into the docking station.

2. Prepare the Installation Location

IMPORTANT! Risk of product damage. If T-bolts are left in place, they will damage the toilet. Make sure they are removed before moving the toilet into place.

If there are T-bolts extending from the ﬂange, remove them. T-bolts are not required for this installation.

Cut out the inside of the ﬂange area on the template. Position the template with the hole positioned over the ﬂange. It is critical that the centerlines

marked on the template are centered on the ﬂange. Secure the template to the ﬂoor with tape.

IMPORTANT! Because of the unique design of this toilet, the width of the bottom edges of the toilet will vary. The following steps are required because of this variation.

Conﬁrm the template is correctly positioned and centered over the ﬂange. Position the toilet on the template. Make sure the front of the base of the toilet is aligned with the

markings on the template. Position the toilet so an equal amount of shaded area is visible on each side of the template. Conﬁrm the toilet is centered by measuring the amount of space on each side of the template. Directly under the screw holes on each side of the toilet, accurately mark the bottom edge of the

base. The mark should intersect the lines labeled ″C″ and ″A″ or ″B″ on each side of the template.

3. Determine Mounting Block Location

NOTE: There is a small amount of biodegradable, environmentally safe antifreeze added to the toilet tank to prevent freezing during shipment. When the toilet is tipped forward, a small amount of the antifreeze may run onto the ﬂoor. Make sure the ﬂoor is protected. Do not use a rug as protective material.

Position pieces of the box or other protective material on the ﬂoor directly in front of the toilet. Gently tilt the toilet forward until it rests on the front surface.

NOTE: The installation range of the mounting block is marked on the template. Due to variances in the width of the base, the exact location must be determined by the installer.

Measure the width of the base, dimension ″A,″ on the left side of the toilet. From the mark indicating the outside edge of the base, measure inward and mark dimension ″A″ on

the template lines marked ″A.″ Draw a line connecting the marks on each of the lines labeled ″A.″ Measure the width of the base, dimension ″B,″ on the right side of the toilet. From the mark indicating the outside edge of the base, measure inward and mark dimension ″B″ on

the template line marked ″B.″ Draw a line connecting the marks on each of the lines labeled ″B.″

IMPORTANT! Dimension ″C″ is the distance between the inside edges of the right and left base. The distance between the outside edges of the mounting blocks should be slightly less than dimension ″C.″ The distance between the edge of the outside edge of the mounting block and the inside edge of the base must be 1/16″ (2 mm) or less, or the strength of the mounting block will be compromised.

At the location of the screw holes in the side of the toilet, measure the width of the opening from the inside edge of each side of the base, dimension ″C.″

Kohler Co. 13 1132336-2-D

Determine Mounting Block Location (cont.)

Measure dimension ″C″ on the template, starting at the inside line. Position a mounting block in the area indicated on the left side of the template. Align the outside

edge of the mounting blocks with the inside line. Insert a pencil into each of the four pre-drilled holes in the mounting blocks and mark the center of

the holes. Remove the mounting blocks. At the four locations where the centerline in the slots marked on the template and the pencil mark

indicating the hole locations meet, drill a 3/16″ pilot hole or 1/2″ (13 mm) hole if anchors will be used.

If anchors will be used, insert one of the supplied anchors in each of the holes. Remove the template.

Install the Toilet (cont.)

Let the toilet fully reﬁll and check for leaks.

Secure the Toilet

Insert the bushing into the screw hole in the side of the toilet. Insert the supplied screws into the screw holes.

NOTE: A ratchet style screwdriver is the most effective tool when tightening the screws due to their close proximity to the ﬂoor. It is difficult to achieve enough force with a standard screwdriver. There is a greater risk of stripping the screws when a drill is used.

Thread each screw into the mounting blocks. Tighten the screws evenly to maintain the correct toilet position.

Install the caps over the bushings. Check the toilet to make sure it is level and does not rock. Shim if necessary to level or eliminate rock.
