INSTALLATION
1. How To Install The Faucet
To perform installation, installer must provide G1/2˝ female supply fittings, spaced 150mm
apart and horizontally. The supply fittings should be vertical and not beyond the finished wall.
Hot supply pipe must be located on the left.
Install the two offset connectors(1) into the hot and cold supply pipes. Use appropriate thread
sealants or thread tape on pipe threads. Adjust the center-to-center distance between the
connectors to 150mm and horizontally. They should extend 40 to 45mm beyond the finished
wall. Thread the escutcheons(2) onto the connectors until they are against the finished wall.
Put the washers(3) into the nuts(4), thread the nuts to connectors. Tighten the nuts with strap
wrench or soft cloth between product and regular wrench.
CLEANING INSTRUCTIONS
All Finishes: Clean the finish with mild soap and warm water. Wipe entire surface completely dry with clean soft cloth. Many
cleaners may contain chemicals, such as ammonia, chlorine, toilet cleaner etc. which could adversely affect the finish and are
not recommended for cleaning.
Do not use abrasive cleaners or solvents on Kohler faucets and fittings.
Ensure that all connections are tight. Ensure that the handles are in the off position.
Turn on the drain and main water supply, and check for leaks. Repair as needed.

CARE AND MAINTENANCE
2. How To Install The Shower Column
Select a location in vertical wall to install shower column according
to rough-in dimensions.
Drill the lower hole as anchors(5) diameter and lower base(7-1)
position in the finished wall (NOTE: The arrow in the base is
upward). Press anchors into the hole, secure the base by the
screws(6).
Rehearse the slide bar kit(8) installation for the upper base(7-2)
mounting location determination. Slide the tube joint(9) onto the
slide bar kit, and connect them to the base(NOTE: The arrow in
the base is up). Install the screws(11) into the tube joint with the
hex wrench(10), and tighten them.
Place the slide bar and the body
against the finished wall. Connect
the lower base and the diverter body
kit(12). Position and tighten them by
hex wrench. Mark the hole of upper
base(7-2) with a pencil. Uninstall the
slide bar kit and tube joint.
(NOTE: Don’t lose the screws.)
Drill holes on the mark. Press the
anchors into the holes. Secure the
upper base(7-2) by the screws. Install
the tube joint(9) to the base(7-2) and
tighten them by screws. Reinstall the
slide bar kit with escutcheons(13)
to the bases. Tighten the screws with
the hex wrench. Screw the
escutcheons with the bases until
against the finished wall.
Install the tube kit(14) into the slide
bar kit. Install the nut(15) onto the
tube kit with soft cloth between
internal hole of the nut and the
tube kit. Then screw the nut onto
the slide bar kit with strap wrench
or soft cloth between the nut and
regular wrench.
3. How To Install The Handspray & Hose
Remove the guards on the outlet connectors of 500mm
length hose(17). Connect the outlet(16) to the connector
(18) with the hose(17), and tighten.
Turn the diverter handle(19), run hot and cold water for
about one minute to remove any debris.
Remove the guards on the outlet connectors of 1500mm
length hose(20). Tighten the shorter connector(20-1) of the
hose(20) to the connector(21). Put the restrictor(22) into the
handspray(23) inlet if needed. Tighten the handspray to the
longer connector(20-2) of the hose.
4. How To Install The Showerhead
Turn the diverter handle(19), run hot
and cold water for about one minute
to remove any debris before the
showerhead(24) is installed.
Take out the washer(26) and install
the restrictor(25) into the showerhead
as shown if needed, reinstall the
washer. Tighten the showerhead onto
the tube kit outlet with strap wrench.
Stopper Adjustment
If the flow can’t meet the demand, it can be adjusted(Fig.1). Uninstall the handle
kit and adjust the position of stopper. Turn the counter-clockwise to increase the
flow rate; turn clockwise to decrease the flow rate.
NOTE: When you reinstall the handle, make sure the flow valve in the “close”
position, the button of water flow handle should be aligned with the 37 mark.
Tighten the screw. Put on the handle plug.
Verification And Setting
Make sure that the water feeds of the faucet have reach their highest temperature
by letting the water run sufficiently. With the selector in position 37ºC, the
temperature of the water coming out of the faucet must be within a range of 36ºC
and 38ºC, as measured by a thermometer. If this is not the case, the installer can
adjust the setting. Proceed with the setting as follows: Remove the handle plug.
Untighten the screw with the screwdriver, remove the handle kit. With the faucet
on “cold” normal water flow, slowly turn the temperature selector(always in the
same direction) until water at 37ºC is obtained. If the temperature goes over 38ºC,
go back to the “cold” setting and set again. When the temperature is stabilized,
without turning the cartridge spindle, make sure the reference mark of the
temperature handle aligned with the number 37. Tighten the screw, put on the
handle plug(Fig.2).
After cleaning, install the “stop assembly”
back on the cartridge, adjusting the stop pin
into the notch(Fig.4). Install the assembly
cartridge and stop in the body, adjusting the
stop pin into the notch(Fig.5).
NOTE: Do not turn the cartridge when
reinstall it. If you turned it without carefully,
you should adjust it and be sure that the
round mark is correctly in line with the
groove(Fig.6), or readjust as per the steps
of verification and setting.
Install the temperature selector(without
turning the spindle) lining the number 37
with the reference mark. Tighten the handle
with the screw. Put on the handle plug.
Very hard water can obstruct the filters
proteccting the thermostatic cartridge
and reduce the flow of water. Please
clean the cartridge as follows: Shut off
the water supply of the faucet and open
the water flow handle, then proceed to
remove the cartridge. The cartridge is
sensitive, please be careful.
Mark sure the reference mark is aligned
with number 37 before your action.
Remove the handle kit(Fig.1), unscrew
the nut and stopper(Fig.2). Removing the
cartridge cautiously(Fig.3). Clean the
thermostatic cartridge by soaking it in
warm vinegar.
The filters(27) protecting the
faucet device may get obstructed
and reduce water flow. When this
happens, unscrew the bushes(28,
left thread) by a wrench(12mm)
and take out the nuts(29), filters
(27) and the check valves(30)
after removing the faucet. Clean
the filters by soaking them in
warm vinegar. Reinstall them as
the figure. (Note: Check valves
should reinstall as original
orientation).
