bottom edge.
e. Apply additional sealant around bottom of base. Seal must have a minimum 1/2” radius to
prevent crevices and to ensure a complete seal.
f. Allow sealant to dry to MFG recommendations.
g. Assemble washers and nuts to bolts from underneath the countertop. Tighten rmly.
DO NOT OVER TIGHTEN!
C. CONNECTION TO ELECTRICAL POWER
WARNING
THIS UNIT MUST BE PROPERLY ELECTRICALLY GROUNDED TO AVOID POSSIBLE FATAL
ELECTRICAL SHOCK OR SERIOUS INJURY TO THE OPERATOR. THE POWER CORD IS
PROVIDED WITH A THREE-PRONG GROUNDED PLUG.
IF A THREE-HOLE GROUNDED ELECTRICAL OUTLET IS NOT AVAILABLE, USE AN APPROVED
METHOD TO GROUND THE UNIT.
DO NOT USE EXTENSION CORDS WITH THIS UNIT. DO NOT “GANG” TOGETHER WITH OTHER
ELECTRICAL DEVICES ON THE SAME OUTLET.
1. Connect power supply cord to back of unit (Fig. 3.1)

NOTE:
Water Regulation is highly recommended. Set water regulator to 65 PSIG.
Water pipe connections and fixtures directly connected to a potable water supply shall be sized,
installed and maintained in accordance with federal, state and local codes.
D. CONNECTING SUPPLY LINES TO SOURCES
1. Use beverage barb ttings (1/4”) to attach inlet water and syrup concentrate to ex tubing
located at end of shut-off modules. Water and syrup concentrate lines are identied in Fig 3.2.
Tubing can be routed through a hole in the countertop. Ensure proper size hose clamps are
used to secure tubes.

control (see Fig. 4.3).
G. Repeat process for each syrup valve.
H. Remove syrup separator when adjustments are completed.
Replace with dispenser nozzle.
5. CLEANING AND SANITIZING
The Schroeder America Dispenser is shipped from the factory cleaned and sanitized in accordance
with NSF guidelines. The dispenser must also be cleaned and sanitized after installation is
complete. It is recommended that the operator provide continuous maintenance as required by the
manual and/or state and local guidelines to ensure proper operation.
A. External/Internal Cleaning Solutions:
Cleaners (ivory liquid, calgon, etc.) should be mixed with clean potable water at a temperature
of 90 to 110 degrees F. The acceptable mixture ratio is one ounce of cleanser to two gallons
of water. Any NSF approved equivalent cleaner may be used. Rinsing must be thorough using
clean potable water.
B. Internal Cleaning:
1. Remove top cover.
2. Wipe inside of the dispenser with a clean cloth.
3. Inspect to make sure any product residue has been removed.
4. Wipe with a clean soft cloth.

IMPORTANT
ONLY USE INTERNAL CLEANING SOLUTIONS THAT ARE APPROVED FOR BEVERAGE
DISPENSER APPLICATIONS, SUCH AS BevClean™. (NO CAUSTIC CHEMICALS SUCH AS
INDUSTRIAL KITCHEN CLEANING CHEMICALS SHOULD EVER BE USED)
C. External Cleaning:
The stainless steel dispenser can be cleaned by wiping with a cloth soaked with warm cleansing
detergent. Abrasive cleaning or scouring pads should not be used as they will scratch the
dispenser nish.
NOTE:
Nozzle and diffuser must be cleaned daily.
D. Daily Cleaning - Nozzle and Diffuser
1. Remove nozzle by twisting clockwise and pull down. Diffuser is not removable.
2. Wash nozzle and diffuser with warm water. Ensure cleaning solution is rinsed off. Residual
Solution will cause product off taste.
3. Reinstall nozzle by twisting counterclockwise while pushing up.
NOTE:
Nozzle and diffuser must be sanitized biweekly. Ensure sanitary gloves are used for this procedure.
E. Biweekly Sanitizing - Nozzle and Diffuser
1. Prepare sanitizing solution:
Prepare with a food grade non-ammonia, non-chlorine based sanitizing solution with clean
potable water at a temperature of 90 to 110 degrees F.
Any chlorine/ammonia free sanitizing solution may be used and must be prepared according
to manufacturer recommendations and safety guidelines.
2. Remove nozzle by twisting clockwise and pull down. Diffuser is not removable.
WARNING
DIFFUSER IS NOT REMOVABLE. ATTEMPTING TO REMOVE IT WILL DAMAGE DISPENSER.
3. Inspect nozzle for cracks or breakage.
4. Wash nozzle and immerse in a container of sanitizing solution for 15 minutes.
5. Wash diffuser with warm cleaning solution and inspect.
6. Wash diffuser and sanitize
a. (OPTION 1) Use Nozzle Sanitizing Assy. (P.N. 631-0187) accessory: Fill nozzle with
sanitizing solution and install onto diffuser by twisting counterclockwise while pushing up
onto diffuser. Leave on for 15 minutes.
b. (OPTION 2) If Sanitizing Nozzle Assy. is not utilized, wash diffuser, rinse and immerse in a
food grade non-ammonia, non-chlorine based sanitizing solution for 15 minutes.
7. While the parts are soaking, visually inspect around the nozzle mounting area for syrup
residue and wash area with cleaning solution.
8. Remove sanitizing nozzle from diffuser. Air Dry.
9. Remove nozzle from bath; air dry before re-installing onto diffuser.

F. Sanitizing Water Circuits:
Cleaning and Sanitizing are not required for potable water circuits. The potable water lines
should remain connected during the cleaning procedures for the concentrate circuits to avoid
contamination.
1. Disconnect concentrate container from product line.
2. Attach product line to container containing sanitizing solution mixed to mfg. recommendations
(100 ppm is recommended)
a. Using yellow Shut-off, turn incoming water off.
NOTE:
Sanitizing solution temperature should be between 90˚ to 110˚ F (max).
3. Prepare enough solution to sanitize from the concentrate source to the dispenser.
NOTE:
OPTIONAL - using a tment removed from a bag in box container. Attach tment to concentrate
tting. Prepare sanitizing solution in a container and set tment/tting assembly in solution.
4. Press appropriate switch position, solution will begin to ow towards dispensing valve.
5. When color turns clear, concentrate line is full of sanitizer solution.
6. Wait 15 minutes.
a. Reconnect concentrate product line.
7. Purge sanitizer from line with concentrate product.
8. Purge until concentrate is owing from dispensing valve.
9. Using yellow Shut-off, turn incoming water on.
10. Taste the beverage to verify that there is no off taste.
11. Repeat for every product or as needed.
WARNING
FLUSH SANITIZING SOLUTION FROM CONCENTRATE LINE AS INSTRUCTED. RESIDUAL
SANITIZING SOLUTION LEFT IN SYSTEM COULD DAMAGE LINES AND DISPENSER PARTS.
IT MAY ALSO CREATE A HEALTH HAZARD.
