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.
