Instructions from the bag containing the supplied saddle tapping valve, if applicable
Step 1: From parts bag locate: saddle tapping valve and 4’ of 1/4” tubing, color coded: red or orange (supply line to unit).
Basic Inlet Supply Water Connection **
CAUTION:Do not turnvalvehandlebefore or while installingthe“saddletappingvalve”.
Make sure the piercing lance does not protrude beyond the rubber gasket. Failure to do this
may result in damage to the piercing needle.
NOTE: For Copper Pipe - go directly to #4.
For Steel or Brass Pipe - follow A, B, C below, then go to #4
A: Drill a 3/16” hole in pipe. Use a hand drill to avoid shock hazard.
B: Turn handle to expose lance beyond the rubber gasket no more than 3/16”.
C: Place body of valve over hole so the lance fits into the hole
Professional Installation Using a Preferred Connection is Strongly Recommended
**Thisunit is supplied with a saddle tappingvalve and should be considered a basic connection for copper,steel or brass
3/8” to 1/2” O.D. pipe prior to the angle stop shut-off of the cold water line to the kitchen faucet. This should be considered
a “do-it-yourself” connection which is not applicable in many situations and may not meet local codes.
Aqualifiedplumber should choose to make theinlet supply water connection by amorepreferred method.
Step 7: Be sure the packing nut is tight, then turn the handle of the saddle tapping valve clockwise
until it is firmly seated. NOTE: For Copper Pipe - the pipe is now pierced.
HINT: Back theend of the piercinglance out, turning thehandle counter-clockwise. Then re-insertby turning the handle
of the saddle tapping valve clockwise until it is again firmly seated. This will clear any possible debris that can
blockpiercinglanceand water flow.
Step 8: Turnthe handle counter-clockwise toopenthe valve for water supply.Keep main line shutoffand proceed with
the remainder of the installation and start-up.
Step 6: Connect the 1/4” plastic tubing to the saddle tapping
valveby following these instructions:
A: Slide 1/4” compression nut over plastic tubing with threads toward the
saddle tapping valve.
B: Slide 1/4” plastic ferrule over plastic tubing with long tapered side
toward saddle tapping valve.
C: Place 1/4” brass insert sleeve into the end of the 1/4” or orange/red
plastic tubing.
D: Insertorange/redtubingintosaddletappingvalve.Leaveotherend
available for system interconnection
E: Tighten compression nut onto saddle tapping valve.
Step 4: Looselyassemblesaddletappingvalve on pipe
A: For all 3/8 O.D. pipe, use side of bracket with side projections
toward or against pipe to prevent distortion of tubing.
B: For all 1/2 O.D. pipe, use “V” side of bracket with that notch
toward or against pipe.
Step 5: Tighten screws evenly. Make sure brackets are parallel,
thentighten firmly until the valveis not moving on the pipe.
CAUTION:Do not over tighten fittings.
Step 2: Locate cold water line that feeds your existing faucet. Determine if there is enough
spaceto install the saddletapping valve on the hard line between the wall and the angle
stop.

WATER.
Step 3: Shut off the main water supply to the house and open the faucet to relieve water
pressure in the hard pipe. NOTE: Shutting the angle stop only, still leaves water in that pipe.
Shut the main supply.
