Basic Inlet Supply Water Connection **
Professional Installation Using a Preferred Connection is Strongly Recommended
**This unit is supplied with a saddle tapping valve 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.
A qualified plumber should choose to make the inlet supply water connection by a more preferred method.
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).

Step 4: Loosely assemble saddle tapping valve 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,
then tighten firmly until the valve is not moving on the pipe.
CAUTION: Do not over tighten fittings.
Step 6: Connect the 1/4" plastic tubing to the saddle tapping
valve by 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" orange/red
plastic tubing.
D: Insert orange/red tubing into saddle tapping valve. Leave other end
available for system interconnection
E: Tighten compression nut onto saddle tapping valve.
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 the end of the piercing lance out, turning the handle counter-clockwise. Then re-insert by turning the handle
of the saddle tapping valve clockwise until it is again firmly seated. This will clear any possible debris that can
block piercing lance and water flow.
Step 8: Turn the handle counter-clockwise to open the valve for water supply. Keep main line shut off and proceed with
the remainder of the installation and start-up.

Step 2: Locate cold water line that feeds your existing faucet. Determine if there is enough
space to install the saddle tapping valve on the hard line between the wall and the angle
stop.
CAUTION: USE ONLY COLD WATER LINE. NOT INTENDED FOR SUPPLY BY HOT
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.
CAUTION: Do not turn valve handle before or while installing the "saddle tapping valve".
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
O: 702.256.8182; M-F 8:30am-4:30pm PST
CAUTION:
Do not over
tighten fittings.
