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
IMPORTANT: 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 housings by unscrewing them . They have a standard
right hand thread .
5 . Clean inside of housing sump with warm water . If desired, disin-
fect 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 cartridges into filter housings .
7 . Make certain the O-ring is properly positioned and reinstall filter
housings . Tighten housings hand tight . Check O-ring for dam-
age and replace if damaged or distorted .
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 .
