•Turn on faucet to drain water from line.
• Connect saddle valve to cold water supply.
Turn saddle valve handle clockwise until
piercing lance enters pipe and stops.
• Connect one end of orange tubing to
saddle valve. Connect other end to

(^ SYSTEM CONNECTION
Decide if the system will be connected
to your refrigerator, to an optional faucet
or to both.
• Connect refrigerator’s water supply to
filtration assembly with blue tubing.
• Or, install faucet in sink and connect
blue tubing to filtration assembly.
• Or, use "T” grey connector to connect
both refrigerator and faucet.
I START UP
• Slide filtration assembly onto mounting
screws.
• Turn on cold water supply.
• If filtration assembly was connected to
refrigerator, make and discard 2 batches
of ice and drain 2-3 gallons of water from
water dispenser.
• If filtration assembly was connected to
sink faucet, lift faucet handle to discard
2-3 gallons of water.
Instructions At A Glance • For detailed instructions see following page.
1. Turn off cold water supply. (Steps 1a-1b)
Special care must be taken when drilling into
water pipes. Some water may remain in water
supply pipe:
• If an electric drill is used, it must be properly
• Use only an electric drill that is double
• Check with qualified electrician if you are in
• Only drill at top or side of horizontal water

! CAUTION
Product Damage
DO NOT connect to a hot water supply line.
Failure to follow this instruction could result in
product damage.
^ Q Take note of water requirements listed under
Ida the Use & Care section of this booklet. The
filtration system's feed line (orange tubing)
connects to your cold water supply line using the
saddle valve.
Do not use saddle valve if it is prohibited by your
state or local plumbing codes.
The saddle valve is for use with %" to %" outer
diameter (O.D.), soft copper pipe (plain or chrome
plated) or rigid metal or plastic pipe. Important: DO
NOT use the saddle valve on flexible ribbed tubing.
The wall thickness of flexible ribbed tubing is thin
and will not support the saddle valve supplied.
If your cold water supply is connected to the cold
water faucet with flexible ribbed tubing, contact your
local plumbing supply distributor to obtain special
connecting hardware.
Important: If local codes do not permit the use
of saddle valves, special feed valves can be
obtained from your local plumbing supply distribu
tor. Use only V4" polyethylene tubing for water line
connection.
! CAUTION
Property/Product Damage
• DO NOT install tubing in an area where
temperatures drop below 32°F.
• DO NOT overtighten saddle valve to copper
pipe. This will crush pipe.
• Keep a bucket or towel under area where
saddle valve connection is made.
Failure to follow these instructions may result in
water damage to property or product damage.
Turn off cold water supply. Turn on cold
