F. INSTALL THE FEED WATER TAPPING VALVE
AND TUBING
The feed water tapping valve which is supplied, is
designed to be used on 3/8" to 1/2" OD soft copper tubing
(plain or chromed) and rigid metal pipe. Do not use it on flexi-
ble ribbed tubing, because it has too thin a wall thickness and
it requires special hardware.
Soft Copper Tubing Installation:
1)
Close the cold water supply valve under the sink, or the
main valve for the house.
2)
Before installing the feed water tapping valve, make sure
that the piercing lance does not protrude beyond the rubber
gasket. (See Fig. 3)
3)
Assemble both halves of the feed water tapping valve onto
the copper tubing.
4)
For 3/8" OD tubing, use the side of the bracket with the
projections to prevent distortion of the tubing. Use the "V"
side of bracket for all larger size tubing. Tighten the
screws evenly and firmly. The brackets should be parallel.
Do not deform the tubing. (See Fig. 3)
5)
To pierce the soft copper tubing, turn the handle clockwise
until it is firmly seated. The valve is closed in this position.
With a wrench, tighten the nut/seal around the valve
handle stem. Open the cold water supply valve.
6)
Remove the cover from the appliance and disconnect the
orange 1/4" tubing from the feedwater fitting. (See Fig. 6)
7)
Connect one end of the orange tubing to the feedwater
tapping valve using the brass compression nut, insert in
plastic sleeve. (See Fig. 3)
NOTE:
For basement installations, the existing orange feed-
water tubing may have to be longer to reach the feedwater tap-
ping valve.
IMPORTANT: Some local plumbing codes may prohibit
the use of saddle-type valves and/or drain connections.
The use of saddle-type valves are prohibited in Alaska,
Delaware, Idaho, Kentucky, Massachusetts, Michigan,
Minnesota, New Hampshire, North Dakota, Ohio, and
South Dakota. Check your local plumbing codes for any
restrictions that apply. Massachusetts CMR 248 strictly
prohibits the use of saddle-type valves. The feedwater
connection must conform to applicable plumbing codes.
Rigid Metal Pipe Installation:
1)
Close the cold water supply valve and drain the line to
prevent spillage.
2)
Drill a 3/16" diameter hole at the desired location on the
pipe. To prevent any electrical shock hazard, use a
battery operated drill.
3)
Turn the feedwater tapping valve handle clockwise to
expose the piercing lance beyond the rubber gasket no
more than 3/16". (See Fig. 3)
4)
Assemble the feedwater tapping valve on the pipe by
inserting the piercing lance into the drilled hole and
tightening the two halves together. Use the "V" side of the
bracket. Tighten the screws evenly and firmly, keeping the
two sides of the bracket parallel.
