Installation Instructions

Important Installation Recommendations

Read entire manual. Failure to follow all guides and rules could cause personal injury or property damage.
Check with your local public works department for plumbing codes. You must follow their guides as you install
the Water Filtration system.
Use the Water Filtration system on a potable, safe-to-drink, home COLD water supply only. The filter cartridges will
not purify water or make unsafe water safe to drink. DO NOT use on HOT water (100° F. max.).
Protect the Water Filtration system and piping from freezing. Water freezing in the system will damage it.
Your Water Filtration system will withstand up to 125 psi water pressure. If your house water supply pressure is
higher than 100 psi during the day (it may reach higher levels at night), install a pressure reducing valve before
the system.
WARNING: Do not use with water that is microbiologically unsafe or of unknown quality without
adequate disinfection before or after the system. GNUL30 is certified for cyst reduction and may be used
on disinfected water that may contain filterable cysts. The water should be tested periodically to verify
that the system is performing satisfactorily. Small parts remaining after the installation could be a choke
hazard. Discard safely.
