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 break 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. GNUL30Z and GXUL30Z are 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.

INSTALLATION OVERVIEW
Locate the drinking water system on the cold water supply pipe, under the kitchen and/or bathroom sink, to filter the cold drinking water.
STEP-BY-STEP INSTALLATION INSTRUCTIONS
FEED WATER SUPPLY
Check and comply with local plumbing codes as you plan, then install a cold feed water supply fitting. For new home installation using
standard plumbing fittings, see Fig. 2A below. A typical installation for existing homes using the saddle valve is shown in Fig. 2B below.
A. PREFERRED INSTALLATION
1. Turn off the cold water supply.
2. Complying with plumbing codes, install a fitting on the cold
water pipe to adapt 1⁄4²OD tubing. A typical connection is
shown in Fig. 2A. Make sure a shutoff valve is used.
B. OPTIONAL HOME INSTALLATION
When codes permit
NOTE: Codes in the state of Massachusetts require installation by
a licensed plumber and do not permit the use of the saddle valve.
For installation, use plumbing code 248-CMR of the
Commonwealth of Massachusetts.
1. Turn off the cold water supply and attach saddle valve as
shown in Fig. 2B.
DANGER: To protect yourself from serious injury or fatal
shock, use a battery powered hand drill only to make the
hole. Do not use an electric drill.
2. Close the water supply/saddle valve by turning the handle
clockwise.
3. Open the main water supply valve and several house faucets to
purge air from the system. Close faucets when water runs
smoothly.
