10. Fixture operates within water pressure range of 20 to 105 psig. Acorn Engineering will not warranty fixtures
damaged when connected to supply lines with flow pressure lower than 20 psig or higher than 105 psig. A
pressure regulator must be furnished by others on supply line if inlet pressure is greater than 105 psig.
11. Due to cold waste water, Acorn Engineering recommends that p-trap supplied by installer be insulated to
prevent excessive condensation.
12. Per UPC 609.10- All building water supply systems in which quick acting valves are installed shall be provided
