PRECAUTIONS

C

arefully read and follow instructions.

WARNING

 Risk of electrical shock. If your water pipes are 

used to ground your house’s electrical system, install a No. 8 
AWG (8.4mm2) jumper wire (or larger) around the filter. The 
jumper wire must be connected at both ends by a pressure wire 
fitting or other connection that satisfies NEC or CEC and local 
codes. Consult a building inspector or licensed electrician for 
more information.

WARNING

 Do not use with water that is microbiologically 

unsafe or of unknown quality without adequate disinfection 
before or after the system.

CAUTION

 Filter must be protected against freezing, which can 

cause cracking of the filter and water leakage.

CAUTION

 The rubber o-ring provides the water-tight seal 

between the cap and the bottom of the housing. It is important 
that the o-ring be properly seated in the groove above the 
threads of the housing or a water leak could occur.

 

CAUTION

 Because of the product’s limited service life and to 

prevent costly repairs or possible water damage, we strongly 
recommend that the bottom of all plastic housings be replaced 
every five years for clear and every ten years for opaque. If the 
bottom of your housing has been in use for longer than this 
period, it should be replaced immediately.  Date the bottom 
of any new or replacement housing to indicate the next 
recommended replacement date.

CAUTION

 Do not use electrical heating tape on this unit.

NOTES: 

For cold water use only. 
The contaminants or other substances removed or reduced by 
this water treatment device are not necessarily in your water. 
Ask your local water municipality for a copy of their water 
analysis, or have your water tested by a reputable water  
testing lab.
Do not install where system will be exposed to direct sunlight.
Filter cartridge life varies depending on filter type, usage, and 
water conditions.
The replacement filter cartridge used with this system has a 
limited service life. Changes in taste, odor, or flow of the water 
being filtered indicate that the cartridge should be replaced. 
Use only OMNIFILTER replacement cartridges.
This installation must comply with all applicable state and  
local regulations.
Use only Teflon

®

 tape without adhesive backing to seal joints. 

Do not use pipe compound (“pipe dope”), sticks, or similar 
compounds with this unit; they contain petroleum derivatives 
which will cause crazing and cracking of the plastic in the  
filter housing.
Use only soap and water to clean filter housing  
and components.
Do not use aerosol sprays (bug spray, cleaning fluids, etc.) 
near the filter. They contain organic solvents which will cause 
crazing and cracking of the plastic in the filter housing.
After prolonged periods of non-use, such as a vacation, it 
is recommended that the system be flushed thoroughly. Let 
water run for 5-6 minutes before using.




Do not use a torch near the unit.
Some harmless bacteria may attack cellulose media cartridges 
(such as the TO1 or RS1). If your cartridge seems to 
disintegrate or develops a musty or moldy odor, switch to a 
synthetic media cartridge or consult the manufacturer.
An activated carbon cartridge may contain a small amount of  
carbon fines (very fine black powder). A new cartridge, after 
installation, should be flushed with sufficient water to remove 
the fines before using the water.
Wear safety glasses during installation.
