For ease of installation, recess the water shut o into the 
wall or place it in an adjacent cabinet. Locate the water 
supply line within the shaded area shown in the illustra-
tion below. Connect the water supply line to the house 
supply with an easily accessible shut-o valve. Do not use 
self-piercing valves.
An in-line filter is required when water conditions have a 
high sediment content.
A reverse osmosis system can be used provided there is 
constant water pressure of 35–120 psi 
(2.4–8.3 bar) supplied 
to the unit at all times. A copper line is not recommended 
for this application.
Installation must comply with all applicable plumbing 
codes.
