Water Connection
1. Connect the water supply to the coffee maker.
a) Apply Teflon tape to a 3/8" plumbing fitting. If a 1/4" line is being
used, you will then need a 1/4 x 3/8" fitting.
♦Teflon tape should be applied in a clockwise direction, going with
the threads when tightening.
b) Thread the fitting into the inlet valve at the back of the coffee maker and tighten
with a wrench.
c) Connect the water line to the fitting.
d) Turn the water on at the source.
e) Plug the coffee maker into the wall outlet.

3. Fill the ingredient dispenser with coffee.
a) Open the front door of the coffee maker.
b) Lift the lid on top of the coffee maker.
c) One section of the ingredient dispenser is larger than the other. The large section is
for the coffee that is expected to have higher consumption. The smaller is for
decaffeinated or lower consumption blends.
d) Fill the ingredient dispensers by pouring coffee through the opening in the lid.
Note:
To simplify the initial
water connection at
your shop, we
recommend using
1/4" polytubing, and
an instant (quick
connect) fitting. For
field installation, we
recommend copper
tubing from the
source, all the way
to the coffee maker.

INSTALLATION AT AN ACCOUNT
This section will assist you with the initial installation, taking into account several possible
circumstances. While not all can be described here, this information can be used in nearly all
types of plumbing you will encounter at a new account.
Placement of the Equipment
The location of the coffee maker placement at an account is a decision that is made with the
contact person at that account. This decision is usually made in advance by your company's
representative. It is important to remember that the coffee maker gets placed in an easily
accessible, and highly visible area for the majority of its customers, and that it is easily
accessible for any service that may be required. It is also important to consider height. The
person who will be filling the ingredient dispensers must be able to easily reach the top of the
coffee maker. There must be adequate room to lift the lid on top of the coffee maker, and to
open the front door. The tables below outline the clearances needed for the area in which the
coffee maker is installed.

Water Filter
We recommend the use of a high quality water filter (such as Everpure Filters). Filters will
eliminate most odors present in water, and will reduce the amount of particles entering the
water tank. The following are basic instructions for installing a cartridge type filter using a
head bracket (Everpure type filter).
1. Assemble the retaining bracket to the filter head.
2. Insert the cartridge into the filter head and turn the cartridge clockwise.
3. Apply Teflon tape to the threaded portion of two 3/8" x 1/4" fittings and screw each
into the filter head.
4. Mount the water filter at an easily accessible place for servicing, such as:
(a) Under the sink against the back or side wall,
(b) On the back of a utility cabinet,
(c) On the back of the coffee maker,
(d) Any location generally within 20 feet of the machine.

Connecting to a Water Supply
Plumbing - Self-Piercing Saddle Valve
The self-piercing saddle valve is used for tapping into larger or odd-sized pipes which you may
encounter, usually in older buildings.
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.
Plumbing - "T" and Reducing "T" Fittings
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.
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.
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.
Note:
A "T" fitting is used
when tapping pipes
commonly used at
the sink stand-pipe
or drinking fountain.

Running Copper Tubing
If the position of the coffee maker is near the water source, by far the simplest route for the
tubing is along the baseboard or straight down the wall. In both cases, the tubing should be
secured to the wall with self-adhesive or nail-on tubing clips.
In other cases, it may be practical to run tubing over the top of suspended ceilings. This helps to
run the water longer distances, up to 200 feet, with no tube showing. Running tubing inside
walls should be completely avoided. It is difficult and time consuming, and does not
appreciably improve the appearance of the installation. Please note, however, that neatness and
the appearance of the installation should be a top priority.
When it is necessary to make a hole in the wallboard, make it with a Phillips screwdriver, rather
than an electric drill. This will prevent hitting electrical wiring, telephone wiring, or a water
supply. If you must use a drill, be certain of what is on the other side of the wall, then proceed.
1. Connect the tubing to the inlet of the water filter.
a) Most filters have an arrow to indicate the direction of the water flow.
2. Connect a section of tubing to the water filter outlet, and run it to the inlet of the
machine.
a) Insert the tubing into the outlet side of the water filter and secure.
b) Coil an extra 18 inches (45 centimeters) of tubing behind the coffee maker to allow
for repositioning of the coffee maker.
c) Do not connect to the machine at this point.
3. Turn off the valve on the water filter head.
a) Some water filters may not be equipped with an inline valve. If this is the case, it is
recommended that one be installed prior to continuing.
4. Open the valve at the main water source.
5. Bleed the water lines.
a) Turn on the valve at the water filter and catch the first gallon (4 liters) of water.
This will remove any stagnant water and air from the line.
6. Turn off the valve on the water filter head.
7. Connect and secure the tubing to the inlet fitting of the machine.
a) Apply a fitting to the inlet at the rear of the coffee maker, using Teflon tape. Keep
in mind that Teflon tape should be applied in a clockwise direction.
8. Test for any leaks.
a) Plug in the machine, and switch the power “on”.
b) Listen for the sound of the tank filling.
c) Check all fittings for any leaks, and tighten where necessary.
