Installation Instructions
This Heavy-Duty Water Filtration System must be properly installed and located in accordance with the Installation
Instructions before it is used.
Check with your local public works department for plumbing
codes. You must follow their guides as you install the Heavy-
Duty Water Filtration System.
Use the Heavy-Duty Water Filtration System on a potable, safe-
to-drink, home COLD water supply only. The filter cartridge will
not purify water or make unsafe water safe to drink.
Protect the Heavy-Duty Water Filtration System and piping
from freezing. Water freezing in the system will damage it.
Your Heavy-Duty Water Filtration System will withstand up to
125 psi water pressure. If your house water supply pressure is
higher than 80 psi during the day (it may reach higher levels
at night), install a pressure-reducing valve before the system is
installed.
