INSTALLATION
1. How To Install The Faucet
To perform installation, installer must provide G1/2˝ female supply fittings(1), 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.
Flush the water supply pipes thoroughly to remove debris. Install the two offset
connectors(2) 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.
Thread the escutcheons(3) onto the connectors until they are against the finished wall.
Put the washers(4) into the nuts(5), 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.

screws(7).
Rehearse the slide bar kit(9) installation for the upper base(8-2)
mounting location determination. Slide the tube joint(10) onto
the slide bar kit, and connect them to the base(NOTE: The
arrow in the base is up). Install the screws(12) into the tube
joint with the hex wrench(11), and tighten them.
Place the slide bar and the body

about one minute to remove any debris.
Remove the guards on the outlet connectors of 1500mm
length hose(21). Tighten the shorter connector(21-1) of
the hose(21) to the connector(22). Put the restrictor(23)
into the handspray(24) inlet if needed. Tighten the
handspray to the longer connector(21-2) of the hose.
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.

tube kit outlet(28) with strap wrench.
OPERATION INSTRUCTIONS
CARE AND MAINTENANCE
Turn the diverter handle of the column counter-clockwise, handspray works; turn it
clockwise, showerhead works.
The temperature is set by slowly turning the temperature selector(right-hand handle).
For safety reasons, there is a stop that limits temperature to 40ºC. To get a higher
temperature, push the button and continue turning the temperature selector.
Water flow is set by turning the left-hand handle. There is also a water-saving stop.
To obtain a higher flow rate, push the button and continue turning it.
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: 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 temperature selector, unscrew
the screw located on the top of handle with screwdriver. Install the handle with aligning
the 37ºC with the mark “O” on the handle. Tighten the screw with the screwdriver.

The filters(29) protecting the faucet device may get obstructed and reduce water flow.
When this happens, unscrew the bushes(31, left thread) by a wrench(30, 12mm) and
take out the nuts(32), filters(29) and the check valves(33) after removing the faucet.
Clean the filters by soaking them in warm vinegar. Reinstall them as the figure.
Very hard water can obstruct the filters protecting the thermostatic cartridge and
reduce the flow of water. Clean the filters by soaking the thermostatic cartridge in hot
vinegar and follow the instructions in the figures on removing and installing the
cartridge(The 37 mark is aligned with the mark on the body before removing). Adjust
temp. as per the steps of verification and setting.
NOTE: Do not turn the temperature selector before reinstall it. Reinstall the
temperature selector by aligning the 37 mark with the mark on the body.
