8 . CHECK VALVE (AIR FILTRATION SYSTEMS ONLY): All air systems include an
internal check valve and screen assembly as part of the air draw system (see diagram at
right) . This check valve, screen, and elbow are exclusive to the air system and are not to
be confused or interchanged with a brine elbow used on a softener . The gray color of
the elbow indicates use with an air system vs . a black elbow which indicates use with a
water softener .
NOTE: Under certain conditions (finished basements, utility room, etc.) it may
be advisable to disconnect the screen and run a 3/8" line close to a
drain, in case of check valve failure and water leakage.
CAUTION: Check valve may be under pressure and can result in sudden release
of part, causing injury.
In order to replace or remove the check valve from the control valve, it is necessary to
relieve the pressure from the system . Place filter into by-pass mode (Fig . 2 Page 4) and release pressure by manually stepping through an entire
regeneration sequence . This will adequately release the pressure on the system so the check valve can be serviced . After servicing, replace part,
secure the check valve assembly with the red clip . Open by-pass to the normal service position (Fig . 1 Page 4) .
9 . OZONE GENERATOR KIT (OPTIONAL): In situations where additional cleaning is needed due to
high levels of iron or sulfur bacteria, an optional Ozone Generator (part # OZ-1-A) may be beneficial . This
optional device produces ozone, a powerful cleaning agent which is used to help reduce service calls due to
nuisance bacteria* . Please refer to the OZ-1-A Installation Instruction guide or consult with your local dealer or
distributor for more information .
*Nuisance bacteria refers to iron and sulfate reducing bacteria which is harmless to human health . This
bacteria can cause slime, taste, and odor issues .
