The Variety Tea Tower dispenser can be configured to
dispense 1 to 4, non-carbonated, post-mix tea prod-
ucts.
Typical installation will have the tower counter mounted
with BIB Pumps and BIB storage rack located in the
immediate area, such as, in the cabinet below or adja-
cent to the tower.
Note: This equipment has been tested and found to com-
ply with the limits for a Class A digital device, pursuant
to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interfer-
ence when the equipment is operated in a commercial
environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and
used in accordance with the instruction manual, may
cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely
to cause harmful interference in which case the user will
be required to correct the interference at his own ex-
pense.
Modifications not expressly approved by the manufactur-
er could void the user's authority to operate the equip-
ment under FCC rules.
POTABLE WATER SUPPLY:
Locate an existing potable water source with
shut-off valve or have a licensed plumber install
shut-off valve with 3/8” connection.
IMPORTANT:
Water pipe connections and fixtures directly
connected to a potable water supply shall be
sized, installed and maintained in accord-
ance with federal, state, and local codes.
The tea dispensing system water supply line
must be connected to the potable water sup-
ply with adequate backflow prevention to
comply with federal, state, and local codes.

PRE-INSTALLATION PLANNING
Confirm the appropriate location for mounting the tower
with the store manager. Typically this will be the same
customer self-service location where all other soft-drink
and beverage dispensing tower equipment is located,
in the “front of the house”.
A. Determine the appropriate location for the tea
BIB pump and storage rack with store manager.
If at all possible, the tea BIB pumps and storage
rack should be located in cabinetry below the Varie-
ty Tea Tower dispenser (Fig.2).
In some instances, where under-cabinet storage
space is not available, the tea BIB Pumps and stor-
age rack will be located in a remotely, such as, next
to the soft-drink BIB pump and storage rack loca-
tion.
B. If the BIB pump and storage rack must be
remotely located, determine the method for
running the syrup bundle overhead from the BIB
pumps to the Tea Tower.
If running through the ceiling, hangers must be
used to secure the tubing to the ceiling so tubing
does not lay on ceiling tiles.
If installing in a chase, the same process is used to
pull bundle tubing as stainless steel.
If running through walls, be careful not to cut
through fire walls or damage any plumbing or elec-
trical systems hidden in the wall(s) Fig.3).

MAKE WATER CONNECTION
1. Connect 3/8” water line at water
source Shut-Off valve (Fig.6).
2. Connect the water source line to the
Reducer Valve’s 3/8” inlet fitting(Fig.7a).
The Water Pressure Reducer Valve
Pigtail (Fig,. 7a, 7b) must be installed.
3. Turn on water supply at the shut-off
valve and check for leaks. Turn off
the water shut-off valve when leak
checking is completed.
REMOTE BIB PUMP AND RACK NOTE:
Remote BIB Pump and Rack installa-
tions, requiring an overhead bundle
tubing run, may not allow through-the-
bottom access for the water and syrup
tubing. In those instances, mount the
tower, remove the rear tubing access
plug cap and route the water tubing
pigtail (with Reducer Valve) and syrup
tubing pigtails through the rear access
hole Fig.8) before making the water
line connection.

MOUNTING THE TEA DISPENSER TOWER
The Dispenser will be typically mounted to one of the follow-
ing surfaces, next to existing self-serve soft-drink and other
beverage dispensers located at the “front of the house.”
 On a laminated wood countertop, or
 On a stainless steel countertop
Installing to a Countertop (Fig.4)
1.
Remove the Splash Plate (See Fig. A & B, C Page 9).
2. Position the tower in the desired countertop location
and mark the tubing access and tower mounting
holes (Fig.5).
3. Cut an access hole through the countertop for the
four (4) syrup and one (1) water tubing. (stainless
steel counters must be cut by an authorized
contractor).
4. Use a 9/32” to 5/16” drill bit to drill the mounting holes.
5. Place a 1/8” wide bead of silicone rubber caulk about
1/4” in from the edge, around the entire perimeter
of the tower base (Fig.5).
6. Use five (5) stainless steel 1/4” bolts and nuts to se-
cure the tower to a stainless steel countertop. Use
five (5) wood screws to secure the tower to laminated
wood surfaces.
7. Smooth the silicone caulk around the entire perimeter
of the tower base.
