Fontana Lima Brushed Nickel Touch-Button Thermostatic Mixer FAQ
Three-Way Outlet Routing, Thermostatic Balancing & Service-Box Access
This brushed nickel concealed shower mixer combines solid brass construction,
automatic thermostatic regulation, and three independently controlled water outlets.
How should the three concealed water outlets be assigned?
Route and label the rainfall, hand-shower, and spout branches during rough-in, then verify that each touch button operates its designated outlet before waterproofing and wall closure.
How should the thermostatic cartridge be commissioned?
Flush the hot and cold supplies independently, establish balanced inlet pressure, and verify stable mixed-water temperature while each outlet is operated under normal flow conditions.
How should the brass shower-switch valves be tested?
Cycle every touch-button control repeatedly and confirm positive engagement, complete shutoff, correct outlet indexing, and no hydraulic communication between inactive branches.
What service clearance must remain after installation?
Keep the supplied mounting box accessible so the thermostatic cartridge, shower-switch valves, internal seals, and control components can be serviced without removing the finished wall.
