Operation
With sufficient pressure, operation of this system is completely auto-
matic . Dependable operation involves only monitoring system pres-
sure differential, periodic filter changes, and service documentation .
Installation
* Please note: All cartridge filters are preinstalled, in the
housings, at the factory.
1 . Turn off all equipment to be fed by the system, locate the water
supply shutoff valve and turn it off .
2 . Thread the inlet and outlet valve and pressure gauge assemblies
into the inlet and outlet of the system . The valve and pressure
gauge assembly with the ¼" (8mm) Quick-Connect fitting is to
be installed on the outlet of the system . NOTE: DO NOT OVER
TIGHTEN THESE FITTINGS INTO THE FILTER HEADS.
3. Anchor the system on a wall stud or suitable mounting material
spanning wall studs . System must be vertical, upright and level .
At this time also mount the 10" remote ice filter housing in the
same manner on the dedicated make up line to the ice maker .
The water from the main filtration system will supply this remote
ice filter with make up water. A plumbing tee can be installed
between the two filter systems so that filtered water can supply
drink stations, brewing machines, and pot fillers BEFORE it
reaches the remote ice filter .
4 . Run a suitable line of at least 1 ⁄
2
" in diameter from the tap water
source to the inlet ball valve on the left side of the system . Brace
the inlet ball valve on the system with a wrench when connecting
the feed water line . NOTE: DO NOT OVERTIGHTEN CONNEC-
TION FITTING INTO BALL VALVE.
5. Select the appropriate size tubing for the equipment being fed,
and connect it to the outlet ball valve of the system . NOTE: DO
NOT OVERTIGHTEN CONNECTION FITTING INTO BALL
VALVE.
6 . Install the ¼" tubing into the compression fitting on the outlet of
the system and hold it over a drain . Open the ¼" drain valve .
7. Once all inlet and outlet piping has been completed, check and
make sure all filter housing are tight, slowly open the inlet valve
and allow all air to purge from the system . Slowly close the ¼"
drain valve, allow the system to reach operating pressure, and
check for leaks .
8 . If no leaks are present, open the ¼" drain line again and allow it
to run to drain for 5 minutes to flush the system then close the
valve .
9 . Open the outlet water valve and check for leaks .
10 . Record the start up date and pressures in this manual .
Note: Overtightening components can damage the system
causing water damage and/or system failure.

Maintenance
Routine maintenance of this system involves periodic filter changes .
The filters should be replaced after 6 months, high pressure differen-
tial (15psi or more), or chlorine breakthrough (10,000 gallons), which
ever 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 .
2 . Open the ¼" drain valve on the outlet of the system to relieve
pressure in the housings .
3 . Press the red pressure relief button on the remote ice filter hous-
ing to remove the pressure from the housing .
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 down-
stream equipment .
11 . Record filter change date in this manual .
