Model 506 (UC Ice Maker)
Water Connection Requirements
Materials needed for installation:
1/4-in. O.D. copper tubing
1/4-in. outlet, saddle-type shut-off valve
(Part No. 4378392)
1/4-in. x 1/4-in. tube union
(Part No. 4378972)
These materials can be obtained locally or from your
FSP Parts Distributor by ordering Ice Maker Installation
Kit No. 978567, which includes 25 feet of copper tubing.
Do not use plastic tubing because it becomes brittle
with aging.
Make sure the saddle valve complies with local plumb-
ing codes. Do not use a self-piercing type or 3/16-inch
saddle valve because they reduce water flow and clog
more easily.
For proper operation, the ice maker should be connect-
ed to an active water supply line delivering cold water
at pressures between 20 and 120 pounds per square
inch.
(See Figure 2-2)
Do not install copper tubing in an area where
temperatures drop below freezing. To do so
may result in water damage.

Installation & Maintenance
Installation of Line Tapping Device and/or Shut-off
Valve
1. Select the point on an active cold water supply line
convenient to the unit where connection is to be
made. A point on a vertical section of 1/2-in. or 3/4-
in. line leading to the kitchen sink is ideal. If
installed on a horizontal line, place valve on top or
side of line; never on bottom. (This will keep water
away from the drill during installation and helps nor-
mal sediment from collecting in the valve.) Turn off
the water supply and clear line of pressure.
2. Provide a length of 1/4-in. O.D. copper tubing for
connecting the ice maker to the water supply. To
determine the length, measure distance from the
unit to the connecting point on supply line, and add
approximately three feet to allow for connection to
the water valve in the unit. Be sure both ends of
copper tubing are cut square.
3. Drill a 1/8-in. hole in water supply line at point
selected for making connection. Care must be
taken to drill a clean hole perpendicular to wall of
supply line. Be sure electric drill is grounded, or
use a hand drill to avoid shock.
4. Be sure the shut-off valve is in the OFF position.
Turn clockwise until the stem is seated.
5. Assemble shut-off valve and pipe clamp and mount
it on the supply line. The inlet tube of the shut-off
valve must extend through the rubber washer and
into the 1/8-in. hole drilled in the line. Tighten the
packing nut. Tighten the clamp screws just enough
for the rubber gasket to ensure a watertight seal.
Clamping too tightly may crush the copper tubing.
6. Slip the compression nut, and then the sleeve, on
the end of the 1/4-in. tubing. Insert the end of the
tube into the outlet end of the shut-off valve as far
as it will go, then screw the compression nut onto
the shut-off valve enough to get a watertight seal.
Place the other end in a sink drain or bucket.
7. Turn on the main water supply. Turn the handle on
the shut-off valve counterclockwise to open the
valve and flush the tubing until the water runs clear,
then close the valve.
NOTE:
Make sure there is a vigorous flow of water
(volume and pressure).
8. Bend the tubing to run it to the installation location.
Position the tubing so it can enter the access hole
located in the right rear of the ice maker cabinet.
The tubing will extend beyond the cabinet front
when the cabinet is pushed back into position.
