Notice to Installer
• Do not discard this manual after installation. This manual contains
important operation, maintenance and precautionary information.
Please present this manual to the user/owner/operator after instal-
lation.
• It is strongly suggested that you read this manual before installing
system to ensure the best possible installation.
• Installation must comply with all local and state plumbing codes
and regulations.
• Connect the system to cold water supply only. Water Temperature
cannot exceed 100°F/37°C.
• System must be installed in a vertical, upright and level position.
• Do not use with water that is microbiologically unsafe or of un-
known water quality.
• Notice to user/owner/operator: Please retain this manual for a
future reference for parts, maintenance, or troubleshooting.
• It is recommended that all personnel responsible for operation and
maintenance of this product read the precautions, maintenance,
and operation sections of this manual.
Installation Precautions
• Do not install system on line pressure above 125psi.
• Do not install the system on a hot water line. Failure to limit the wa-
ter temperature to 100°F can result in housing failure and property
damage.
• Do not connect the system backwards with the feed water line
connected to the outlet.
• Do not use liquid pipe thread compounds for threaded connec-
tions. Use Teflon® tape only.
• Do not solder plumbing connections that are attached to the hous-
ings or inlet/outlet fittings. System damage may occur due to high
temperature.
• Do not allow the system to freeze. Turn off water supply and drain
the system if temperature falls below 32°F.
• Do not install system in direct sunlight or where the system will be
exposed to harsh chemicals or may be subjected to being hit by
moving equipment, carts, mops, or any other item that may cause
damage.
• Allow 3" minimum clearance under the housings for filter replace-
ment.
• If water hammer is evident, install water hammer arrestors before
the system.
• Do not over tighten fitting connections.
• Always back up valves and fittings with a wrench when installing
fittings to avoid over tightening or loosening existing fittings.
• Do not install the unit behind equipment where it may be difficult to
access the system for future filter replacements.
Position the system in a suitable location. The direction of flow
through the system is left to right. Keep this in mind when determin-
ing installation locations. Do not mount the system near any source
of heat. Also do not mount this system over anything that may be
adversely affected by water.

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 cut-off valve and turn it off.
2. Thread the inlet and outlet valve and pressure gauge assemblies
in to the inlet and outlet of the system. The valve and pressure
gauge assembly with the ¼" compression connector 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 two 10" remote ice filter housings
in the same manor on the dedicated make up line to the ice
maker. The water from the main filtration system will supply
these remote ice filters with make up water. A plumbing tee can
be installed between the main filter system and the remote ice
filters so that filtered water can supply drink stations, brewing
machines, and pot fillers BEFORE it reaches the remote ice
filters.
4. Run a suitable line of at least 3⁄4" 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 1⁄4" 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 1⁄4"
drain valve, allow the system to reach operating pressure, and
check for leaks.
8. If no leaks are present, open the 1⁄4" 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 (20,000 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-
ings to remove the pressure from 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 over-tighten 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 this manual.
