In the event of pressure over 5 bar, install a centralised pressure reducer.
Installation advice
Before fitting a tap, it is essential to bleed the pipes, especially in case of new installations.
Given the generally poor quality of drinking water, the use of a central filter at source or of filter
cocks below the basin is recommended.
The installation of filters is essential when fitting traditional taps with a ceramic disc movement
and single-lever mixer taps.
Fitting the cartridge
The socket for the tap structure must be clean and free of any frazes, shavings and impurities,
especially on the washer surfaces; avoid the use of grease, oil, paint or thinners.
Lubricate the diametric O-Rings with silicone-based neutral grease. The tightening of the ring nut
should be free but without any play; the ring nut should fully cover the cartridge plate.
Tighten with 10 ÷ 12 Nm torque. Avoid unnatural overloading of the lever both during use and
during packing, transportation and installation.
Cleaning
A soft cloth is ideal for cleaning the taps. Under no circumstances should abrasive, caustic or
aggressive substances be used.
Chrome - Chrome-plated surfaces should be cleaned with a delicate detergent, or with soap and
water.
To eliminate limescale, detergents containing mineral acids (for example hydrochloric acid) should
not be used and aggressive organic acids (for example acetic acid) only if diluted.
We recommend the use of products with a base of citric acid.
After cleaning, the tap should be thoroughly rinsed and dried carefully.
