Install the Supply Pipework - Single Supply
1. Install the water supply pipes.
2. Use the soldering template to construct a pressure balancing loop, this will
ensure correct alignment with the product.
Note! The loop pack is made from stronger pipe to give the pipework rigidity.
It is not standard copper pipe.
3. Assemble the pressure balancing loop with a tee positioned over each of the
four raised locations on the soldering template.
4. If necessary, make each G½” tee fit snug to the soldering template by slightly
bending one tab on the template outward. Bend the same tab at each tee
position.
5. Repeat with the same relative tab on the remaining three nipple locations.
Note! The face of the G½” nipple must fit flush to the surface of the template.
6. Solder the assembly whilst it is still attached to the soldering template.
7. Remove the pressure balancing loop from the soldering template.
8. After allowing the pressure balancing loop to cool, assemble the G 1/2” male
thread adapter with flow control to the loop.
9. Connect the pressure balancing loop to the water supply.
10. Temporarily install a nipple to each tee. Do not use any sealant.

Install the Support Framework
1. Construct the support framework as shown in the above diagram.
The 2 x 2 should be offset 30 mm from the edges of the 2 x 4’s to support the
pressure balancing assembly at the correct depth.
2. Install the support framework under the pressure balancing loop(s) as
illustrated.
The face of the 2x4’s should be installed flush with the face of the existing
ceiling joists.
Install the Finished Ceiling
1. Install the water-resistant board.
2. Cut out a 229 mm to 235 mm square at the desired installation location.
3. Install the finished ceiling material.

Install the Waterway
1. Insert the concealing plate into the opening. The double ribs of the leak shields
should be facing up.
2. If any of the leak shields make contact with an elbow, make sure
that you enlarge the hole in the back of the leak shield to
32 mm.
Install the Pipe Nipples
1. Remove the pipe nipples.
Note! The minimum distance between the face of the tees/elbows and the
surface of the finished ceiling should be 57 mm. The measurement for typical
installations is 70 mm.
2. Measure the distance from the face of the tees/elbows to the surface of the
finished ceiling. Make any adjustments as needed.
3. Install the nipples into the tee/elbows hand tight.
4. Measure the distance form the end of the nipples to the surface of the finished
ceiling. Make sure that the distance is at least 38 mm and no more than
44 mm.
5. If necessary, cut the G½” pipe nipples to length. Debur the ends.
6. Remove the nipples.
7. Apply thread sealant to the ends of the nipples and re-install the nipples to the
tees/elbows.
8. Run water through the system to flush out any dirt or debris.

3. Install the adapter onto one of the nipples using the 11 mm bit (supplied), 11
mm or 7/16” socket, the extension and the socket wrench.
Note! Use masking tape to hold the bit in place, as the bit could fall off and
cause damage.
Important! The concealing plate should sit loosely at this point. If it is tight
against the ceiling, use a longer pipe nipple.
4. Align the groove in the waterway with the double ribs on the leak shield.
5. Press the waterway into place over the adapter. Secure the waterway to the
adapter with the screw.
6. Make sure that the concealing plate does not turn or move.
Important! If the concealing plate is still loose after this step, then use a shorter
pipe nipple.
7. Repeat the procedure for the remaining waterways.

Install the Sprayhead
1. With the ribs of the sprayhead facing upwards, attach the sprayhead to the
waterway.
2. Using a 3/16” hexagonal wrench, install the hexagonal screws to secure the
sprayhead in position. Do not overtighten.
3. Check the sprayhead for upward and downward movement and make sure
that it sits squarely within the concealing plate.
4. Place the nozzle membrane over the sprayhead.
5. Align the long edge of the membrane with the hinge ribs (horizontal).
Note! For optimum performance, make sure that the membrane is applied
evenly.

6. Applying pressure evenly, press the membrane seal into the sprayhead
groove.
Install the Sprayface
1. Tilt the sprayhead downward so that the ribs on the top of the sprayhead are
exposed.
Note!For product with brushed finishes, align the brush pattern of the sprayfaces
with the direction of the brushed pattern of the concealing plate.
2. Insert the grooves of the sprayface over the ribs of the sprayhead.
3. Press the sprayface down to cover the sprayhead, as illustrated.
4. Using a 5/64” hexagonal wrench, turn the setscrews anti-clockwise until they
are flush with the edge of the sprayface frame.
Important! The setscrews must be flush with the edge of the sprayface frame.
If the setscrews protrude outside the sprayface frame, product damage will
occur.
5. Repeat for the remaining sprayfaces.

Kit - Pressure Balance Loop
Like anything of lasting quality, Kohler tapware and fittings require a certain amount of periodic care to
preserve their lustrous finish. Clean your new Kohler tapware and fittings with a mild soap, rinse thoroughly
with warm water and dry with a clean, soft cloth. The ideal cleaning technique is to always blot dry any
water from metal surfaces.
Allowing water to evaporate on metal will form water deposits. It is important to use a dabbing action to
dry metal, not an abrasive or rubbing action.
Never use cleaners containing abrasive cleansers, ammonia, bleach, acids, or chemicals that can damage
the finish. By taking the time to dry your tapware often, soap and water deposits can be prevented.
Failure to comply with these cleaning instructions may void Kohler’s warranty obligations.
