9 . If no leaks are present, open the
1
⁄
4
" (8mm) drain line again and
allow it to run to drain for 5 minutes to flush the system . Then
close the valve .
10 . Open the outlet water valve and check for leaks .
11 . Record the start up date and pressure gauge values in system
maintenance log .
NOTICE
Overtightening components can damage the system causing
water damage and/or system failure.
Maintenance
Routine maintenance of this system involves periodic filter changes .
Filter cartridges should be changed at end of filter life, due to lack of
filtering performance, or whenever a 15 psi pressure drop or greater
is experienced during normal operation, whichever comes first .
Filter Cartridge Replacement Procedure
Determine whether all equipment connected to the system must
be turned off prior to shutting off water supply from filters.
1 . If required, turn off downstream equipment .
2 . Turn OFF water to the system by closing the inlet and outlet ball
valves .
3 . Open the ¼" drain valve on the outlet of the system to relieve
pressure in the housings .
4 . Remove all filters . The blue filter housings unscrew to the left
when viewed from underneath . They have a standard right hand
thread . The QT style filters are removed by rotating them 1/4
turn to the left and then gently pulling down .
5 . Clean inside of blue housing sump(s) with warm water . If desired,
disinfect housing using a teaspoon of household bleach . Add
to filter bowl and fill with water . Let stand 5 minutes and then
discard and rinse .
6 . Insert new QT style filters into the manifold assembly . Push up
and twist each QT cartridge 1/4 turn to the right to properly
install it into the manifold assembly . When making the 1/4 turn,
the cartridge label should come to a stop facing you .
7 . Insert a new prefilter and, if applicable, the remote filter cartridge
into the blue filter housing(s) . Check O-ring for damage and
replace if damaged or distorted . Make certain the O-ring is
properly positioned and reinstall the filter housing . Tighten
housings hand tight . OneFlow is always the last filter in the
system .
Do not overtighten filter housing, overtightening may damage
O-ring(s), cause water leaks, or affect system performance.
8 . Slightly open the inlet ball valve and fully open the ¼" drain
valve . Once full flow of water flows from the drain port, slowly
open the inlet valve to the full open position . Allow water to flush
to drain for 5 minutes .
9 . Slowly close the drain valve and check the system for leaks .
10 . Slowly open the outlet valve to restore water flow to downstream
equipment .
11 . Record filter change date in system maintenance log .
