Installation
Connect the Power Cord to the Brewer (Brewers With a
Strain Relief Mounted to the Back)
1 Place the water tower on a sturdy surface. Remove the
top and side covers.
2 If the brewer will be operating using 120 Vac, locate the
jumper on the terminal block inside the water tower and
remove the cap, then connect the end of the jumper wire
to the L2 terminal on the terminal block.
3 Loosen the strain relief on the back of the brewer.
4 Feed the end of the power cord into the strain relief.
5 Connect the wires on the power cable to the terminal
block inside the brewer.
6 Tighten the strain relief. Leave the covers off until all the
water tower connections are made, later in the installation
process.
Prepare the Countertop
7 Holes must be cut into the counter top prior to installing
the brewer. The hole pattern is critical for proper
operation. See Figure 3 on the following page. The two

Packed with the unit is a full-size template (Part # WC-

needed for installing the brew heads, touchscreen and
drip tray. The two largest circular holes are for the brew
head assemblies, along with three stud holes for the
mounting plate for each head. Also, there is a circular
hole for the touch screen, along with the two mounting
holes. The drip tray can be inset into the counter or

Consideration must be made for the drip tray drain
system. The drip tray comes with a 1/2” NPT X 3” nipple
and a 1/2” NPT barbed elbow. Either may be used to
connect the drain system (supplied by the purchaser) to
the bottom of the drip tray. See Figure 4 for dimensions.

Install the Brew Heads
Install the brew head assemblies into the countertop in the
correct position. One brew head is designed to be installed
on the right side and the other on the left. The installation
position for each brew head is marked on the attached wires
and tubes. Each brew head has three 1/4–20 studs with
matching nuts and washers for mounting onto the surface of
the counter.
10 Hold a brew head over the group of holes that matches
the markings on the brew head tubing/wiring (right or
left).
11 Insert the tubes and wires into the large center hole and
insert the studs through the three smaller holes, while
pushing the unit down onto the counter top.
12 Secure using one (1) fender washer, one (1) lock washer
and one (1) nut per threaded stud. Repeat for the other
brew head.

*The elbow may only be used on drip tray installations
that are open wide enough on the bottom to allow access
to the barb connection.
9 Install the drain system. Be sure to allow room under the
countertop for the water tower.

Install the UCM Assembly
15 Locate the wiring harness and UCM plugs coming from
behind the water tower. Push the plugs up though the
touchscreen cutout in the countertop and plug them into
the receptacles in back of the UCM. These will snap and
lock into place.
16 Install the UCM and holder onto the countertop. Slip the
two 1/4–20 threaded studs into the countertop and fasten
the holder to the counter using one (1) fender washer,
one (1) lock washer and one (1) nut per threaded stud.
Install the Water Tower
17 Remove the screws from the cable support plates,
attached to the control cables coming from the brew
heads. Insert the cable support plates into the slots on
the back of the chassis. Run the cables through the
holes. The cables for the right and left brew heads route
through the two cable ports on the right. The left port is
for the UCM controller cable.
