OPERATION INSTRUCTION
Temperature Verification and Setting
Make sure that the water feeds of the faucet have reached their highest temperature but within the recommended
range 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 the temperature out
of the range, the installer can adjust the setting. Proceed with the setting as follows:
Remove the temperature 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 37ºC, go back to the “cold” setting and set again.
When the temperature is stabilized, do not turn the cartridge spindle, reinstall the handle kit.
Clean Thermostatic Cartridge
Very hard water can obstruct the filters on thermostatic cartridge and reduce the flow of water. Please clean the
cartridge as follows:
Shut off the water supplies of the faucet and open the flow valve, then proceed to remove the cartridge. The
cartridge is sense part, please be careful.
Make sure the handle is aligned with the number 37 on faceplate before your action. Remove the temperature
handle kit. Remove stem, detent and stop assembly(Fig.1). Removing the thermostatic cartridge cautiously(15).
Clean the thermostatic cartridge by soaking it in warm vinegar.
After cleaning, make sure that the black dot is correctly in line with the black line. Install the “stop assembly” back
on the cartridge, adjusting the stop pin into the notch(Fig.2). Install the cartridge and stop assembly into the body,
adjusting the stop pin into the notch(Fig.3). Reinstall the ring and screw. Reinstall the temperature handle kit and
align the handle to the “37” on the faceplate.
