Installation Precautions
• Do not install system on line pressure above 85psi, if water pres-
sure is over 85psi (8 .6 bar) . Watts recommends the installation of a
Watts Pressure Regulator .
• Do not install the system on a hot water line. Failure to limit the
water temperature to 100°F (38°C) can result in housing failure and
property damage .
• Do not connect the system backwards with the feed water line
connected to the outlet .
• Do not use liquid pipe thread compounds for threaded connec-
tions . Use Teflon ® tape only .
• Do not allow the system to freeze. Turn off water supply and drain
the system if temperature falls below 32°F (0°C) .
• Do not install system in direct sunlight or where the system will be
exposed to harsh chemicals or may be subjected to being hit by
moving equipment, carts, mops, or any other item that may cause
damage .
• Allow 3" (76mm) minimum clearance under the housings for filter
replacement .
• If water hammer is evident, install water hammer arrestors before
the system .
• Do not over tighten fitting connections.
• Always back up fittings with a wrench when installing fittings to
avoid over tightening or loosening existing fittings .
• Do not install the unit behind equipment where it may be difficult to
access the system for future filter replacements .
Position the system in a suitable location . The direction of flow
through the system is left to right . Keep this in mind when determin-
ing installation locations . Do not mount the system near any source
of heat. Also do not mount this system over anything that may be
adversely affected by water .
