Suprema - Operation & Service
WARNING:
Be certain of the type of water supply line you tap into. DO
NOT connect the coffee maker to a fire sprinkler water supply as this is a
very high pressure line. Connect to a drinking water supply only.
1. Position the valve over the pipe it is to tap into.
a) With the valve gasket in place around the needle, tighten the screws or
bolts that clamp the valve to the pipe from both sides. Be extra careful not
to crush the pipe.
2. Tap into the pipe.
a) Turn the valve knob clockwise until it pierces a hole in the pipe. The
water will not start flowing at this point.
3. Attach your tubing to the outlet of the saddle valve.
a) Use the insert and the ferrule provided with the valve.
b) Tighten the nut.
CAUTION:
There are potential problems when using a self-piercing saddle valve. It is
important when clamping the valve to the pipe that it remains straight. When you tighten the
nut on the outlet tubing, make sure the valve remains stationary on the pipe. Movement of the
valve will cause the needle to move, creating an oversized hole in the pipe, resulting in a leak.
1. Remove a 1" (2.5 cm) section of pipe being tapped, with a tubing cutter.
2. Insert a "T" in the space created.
a) Use a 1/4 x 1/4 x 3/8, or a 3/8 x 3/8 x 3/8, or a 1/2 x 1/2 x 3/8, depending
on the size of the piece of pipe that has been cut out. If using 1/4 tubing,
the last measurement of the above three descriptions should be 1/4.
3. Secure the fittings.
a) Using "T's" and reducing "T's", insert the compression ferrules.
b) Carefully tighten the nuts.
4. Attach and secure the tubing.
a) Insert the tubing into the "T" with a compression ferrule.
b) Tighten the compression nut.
