Installation Overview
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. GX1S15C (rev. 2)
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.
■ Slotted and Phillips screwdrivers
■ Pliers and adjustable jaw wrench
■ Hand or battery powered drill and 1⁄4″ bit (saddle valve
installation)
■ Electric drill and drill bit to drill 3⁄4″ hole (type as
required) if mounting hole is needed for faucet
Be sure to use the proper procedure for drilling porcelain or
stainless steel. Special drill bits may be needed.
CAUTION: To avoid damaging the sink, consult a qualified
plumber or installer for drilling procedures. Special drill
bits may be needed for porcelain or stainless steel.
