Selecto SMF Series Installation & Operation Manual page 5

All SMF Series Modular Filter Systems are factory pressure tested. It is normal to experience leaks of a few drops of
water at the various O-Ring sealed junction points at initial Start-Up only. This will subside after a few minutes as soon as
the O-Rings become under pressure and seat properly. For any leaks lasting longer than this, or those that are more
than a few drops, please see the troubleshooting points below. Note: The inlet valve
in vertical position), and pressure relieved by pushing the "Red" pressure relief button
leakage problems.
1. Leaks at threaded connection points.
This type of leak should be repaired by removing the
fitting and applying additional thread sealant compound.
Do not attempt to repair by tightening the fitting more!
Overtightening fittings into plastic parts may cause the
plastic to crack. This type of damage is considered
abuse, and not covered by the warranty!
2. Leaks at Junction of Modular Fittings to Filter Head
If leaking persists at the junction points, remove the
retainer clip carefully by inserting a screwdriver or other
object into to the hole and gently prying "UP" to remove.
Gently remove the leaking fitting by "pulling straight out".
Apply additional lubricant (supplied) to the O-ring and
re-insert the fitting by gently "pushing all the way in" until
the shoulder on the fitting contacts the filter head.
Examine the retaining clip for any cracks from removal
and re-insert by "pushing straight down" until it is all the
way in. If retaining clip is cracked or stretched in any
way, discard it and use a new one (supplied). If the
above procedure does not cure the leak, repeat the
processes above, replacing the O-Ring (supplied). See
diagram below.

3. Leaks Between Cartridge and Filter Head
While looking at the top of the filter system, grasp the
cartridge and turn slightly counter-clockwise, when
viewed from bottomand then back clockwise, making
sure that the ears on the cartridge are fully engaged
into the filter head. The round locking tab in the filter
head will be engaged into the half-round recess in the
cartridge ear. See diagram below.
4. If leakage persists, remove cartridge by following the
procedures outlined in "Step 1" of the Cartridge
Changing Instructions on Page 5. Inspect the O-Ring
on the top of the cartridge for damage. Replace with a
new O-Ring (supplied) and lubricate well with lubricant
supplied. Replace the cartridge by following the
procedures outlined in "Step 2" of the Cartridge
Changing Instructions on Page 5. See diagram below.
