Important Safety Information

UF SERIES WATER FILTRATION SYSTEM

IMPORTANT SAFETY INFORMATION (continued)

The following warnings and cautions appear throughout this manual and should be carefully observed.

•Disconnect the power source before performing any service or

maintenance on the unit.

•All electrical connections must be in accordance with local electrical codes and any other appli- cable codes.

•WARNING ELECTRICAL SHOCK HAZARD. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH.

-Do not modify the power supply cord plug. If it does not fit the outlet, have a proper outlet installed by a qualified electrician.

-Do not use an extension cord with this appli- ance.

•If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similarly qualified person.

•This equipment is to be installed to comply with the local plumbing code and any other applicable code.

•Water pressure must not exceed the membrane differential pressure of 45 psig (3.1 bar). To reduce water pressure, install a water pressure regulator and set system inlet water pressure to 45 psi (3.1 bar).

Protect from becoming dry

If the membrane dries out, irreversible damage to the membrane may result. Protect the filter from becoming dry by keeping it wet and sealed at all times.

Protect from freezing

If the membrane freezes during operation or storage, irreversible damage to the membrane and brittle crack- ing of the cartridge or housing may result.

Protect from direct sunlight or other UV sources

Avoid long-term exposure to direct sunlight or other UV sources. The filter should be stored in a dark spot.

Protect from high temperatures or abrupt variation in temperature

The maximum operating temperature is 100oF (40oC). Avoid abrupt variations in temperature. Any tempera- ture variation should be made slowly.

Protect from rough handling or dropping

Mechanical damage, external breakage, and/or internal breakage of the filter can result if the system is dropped or bumped. Handle with care at all times during trans- portation and installation.

Protect from organic solvents and concentrated acids

Prevent any and all contact of the membrane with strong solvents, solvents containing chlorine, or con- centrated acids. Do not use strong solvents or con- centrated acids on any plastic parts of the filter system. Examples of some solvents to avoid: acetone, methyl acetate (nail polish remover); hexane (spot removers); turpentine, toluene (paint thinners); dry cleaning solu- tions, insecticides.

Protect from abrasive material

The membranes must be protected from abrasive materials like shavings left in a pipe. Abrasive materials in contact with the membrane can cause irreversible damage to the membrane. All pipes must be flushed clean before installing the filter. All plastic parts of the filter system must be protected from sharp objects like knives, sand paper or other tools. Cutting or nicking a plastic part can weaken it and cause a leak. Do not use abrasive cleansers on any plastic parts.

Protect from water hammer

The system must be protected from shock, pressure surges, or pulsation that may occur inside water pipes. Water hammer occurs in pipes when a valve or faucet shuts quickly. Install a water hammer arrestor (pres- sure vessel containing compressed air separated from the water by a diaphragm) to reduce pressure shock.
