The Escale toilet is part of a distinctive design suite from Kohler that adds an integrated, contemporary Japanese style to a bathroom environment that is sleek in appearance and efficient in function. The design of the Escale toilet requires some variation on a standard toilet plumbing configuration that can be easily adapted and the installation procedure only differs slightly from a standard toilet.
Complete a preliminary check to verify that the floor waste drain and water supply valve locations meet the manufacturer's specifications.
Remove the rubber gasket from the waste tube. Tilt the toilet bowl forward and attach the upper opening of the waste tube to the outlet of the toilet bowl.
Move the toilet bowl into its installation position. Verify that the waste tube accurately inserts into the waste floor drain. With the toilet bowl in position, also check that there is a minimum 1 inch gap between the wall and the rear face of the toilet base.
Scribe the outline of the toilet bowl base on the floor using a pencil. Remove the toilet base and set it aside.
Align the toilet bowl template provided with the toilet bowl base outline scribed in Step 4. Use masking tape, as needed, to hold the template in place.
Drill two 9/16 inch holes at the points designated on the template to a minimum depth of 1 1/2 inches deep using an electric drill, then remove the template. Insert one of the plastic expansion anchors provided into each hole.
Reinstall the rubber gasket onto the lower end of the waste tube. Tilt the toilet bowl forward and slide the waste tube into place over the bowl outlet. Insert the foam block provided between the waste tube and the surface directly above it. This foam block acts as a support to prevent the waste tube from shifting during insertion into the floor waste line.
Stack two 2-by-4 wood blocks on each side of the toilet bowl location, then rest the toilet bowl on the blocks. The blocks should hold the bowl base 3 inches above the floor directly over the installation position.
Wrap the threads of the water supply valve connection and connect the water supply hose provided to the supply valve using an adjustable wrench. Route the supply hose up through the hole next to the tank connection on top of the bowl surface.
Apply ring lubricant or soapy water to the waste tube gasket. This helps the gasket seat properly into the floor waste line.
Lift the toilet bowl up slightly, with the helper, to remove the support blocks. Lower the toilet slowly down into place, making certain the waste tube slides fully into the floor waste drain.
Slide one of the flat washers provided over the end of one of the floor bolts. Insert the floor bolt into either floor bolt hole next to the bowl opening and vertically downward into the plastic anchor installed in Step 6. Tighten the floor bolt until snug using the hexagonal wrench provided.
Repeat Step 12 for the other floor bolt, tightening both floor bolts evenly until the toilet base is held firmly to the floor.
Place the rubber sealing ring on the bowl valve opening at the rear top centre of the toilet base.
Connect the water supply line to the water inlet connection on the bottom of the toilet tank.
Set the toilet tank on the toilet base. Align the carriage bolt holes in the tank with the inset nuts in the toilet base's top surface.
Attach the tank to the toilet base with the carriage bolts provided, first placing a metal flat washer, then a rubber washer onto the bolt and inserting the bolt through the hole in the tank. Tighten the carriage bolts using a Philips screwdriver. Be cautious not to over tighten the carriage bolts which may cause the vitreous china to chip or break.
Open the water supply valve at the wall and the toilet tank's internal shutoff valve to allow the tank to fill with water.
Place the tank lid on the tank and align the flush button with the hole in the tank lid, then thread flush button onto the flush valve. This will secure the tank lid to the tank.
Flush the toilet a couple of times to check for leaks and tighten the connections as necessary.
Assemble the seat brackets by placing the circular base piece under the bracket, positioning the two pieces over the floor bolt hole, then inserting the mounting bolts through the bracket. Thread the mounting bolt into the centre opening in the floor bolt cap. Tighten the mounting bolt using a Philips screwdriver. Make certain to keep the vertical post of the bracket positioned toward the tank. Snap the cover over the bracket.
Set the toilet seat in place, positioned with the hinges over the seat brackets installed in Step 1.
Lift the seat upright and tighten the hinge set screws using a Phillips screwdriver.
To adjust the toilet tank's water level, turn the styrofoam float clockwise to lower the water level and counterclockwise to raise the water level.
The Kohler Escale toilet does not use a standard toilet flange and is designed to connect directly to a 4-inch diameter PVC waste line. For replacement installations, the existing flange assembly must be below the floor surface or removed. The Kohler Escale toilet requires two persons to lift into place and enlisting the assistance of a helper is required to complete this procedure.
