PEDAL OPERATED TAPS AND MIXERS
TECHNICAL NOTES, INSTALLATION AND MAINTENANCE ADVICES

Q The whole range of pedal operated taps and mixer is supplied complete of stainless steel filters. It is very important to bleed the piping before to
instal the fittings.
Q All the mixers are supplied with a temperature limiting device ring to avoid scalding and to reduce the consumptions. Taking away the limiting
device ring is obtained the maximum temperature.
Q If the model has built-in the flow regulator, after the installation it is opportune with a screwdriver reduce the water consumption at the minimum.
If the flow regulator is not incorporated we suggest to use the RIVER spouts with built-in the automatic flow reducer that gives a water consumption
of 7 l/min. from 0,5 to 9 bar avoiding also unpleasant spurts of water.
Q For a correct installation all the wall-mounted pedal models are supplied with TEMPLATE.
