INTRODUCTION

These dispensers are designed to mix liquid tea concentrate with water to produce iced tea by the glass or pitcher. The
concentrate can be stored either inside the dispenser, or outside with a hose connection to the dispenser. The dispenser
must be placed on a sturdy counter or shelf.

PLUMBING REQUIREMENTS

This dispenser must be connected to a cold water system with operating pressure between 30 and 90 psi
(0.138 and 0.620 MPa) from a 1⁄2" or larger supply line. A shut-off valve should be installed in the line before
the dispenser. The water inlet fitting is 1/4" flare.

NOTE - Bunn-O-Matic recommends 1/4" copper (or 3/8" braided flex) tubing for all installations from the 1⁄2"
water supply line. A tight coil of copper tubing in the water line will facilitate moving the dispenser to clean the
counter top. Bunn-O-Matic does not recommend the use of a saddle valve to install the dispenser. The size and
shape of the hole made in the supply line by this type of device may restrict water flow.

As directed in the International Plumbing Code of the
International Code Council and the Food Code
Manual of the Food and Drug Administration (FDA),
this equipment must be installed with adequate
backflow prevention to comply with federal, state
and local codes. For models installed outside the
U.S.A., you must comply with the applicable Plumb­ing /Sanitation Code for your area.

FAUCET UNDER PRESSURE

1. Remove dispenser from the box and place on a sturdy, level counter.

2. Remove the brass cap and any packing material from the end of the water inlet fitting located on the rear of
the dispenser.

3. Attach a 1/4" water line to the inlet fitting. This supply line must have at least 30 psi of pressure.

4. Using a screwdriver, turn the adjustment screw on the venturi mixer clockwise until the screw contacts the
seat (DO NOT OVERTIGHTEN THIS SCREW!).

5. Turn on the water supply and open the water inlet valve on the rear of the dispenser and check for leaks in
the system.

6. Place a container under faucet(s); fully open the faucet(s) for approximately 10 seconds to remove all the air
out of the lines, then close the faucet(s). Discard the water.

7. Connect the proper BIB (Bag in a Box) adapter(s) to the concentrate inlet tube(s) and clamp. If bottle con­centrate is used, connect the stainless formed tube(s) to the inlet hose(s) and clamp.

8. Attach the connector(s) to the BIB, or insert the bottle adapter into the bottle(s).

9. Place the concentrate container(s) in the location they will be used for normal operations.

a. In the dispenser housing: Coil the tube in the dispenser and place the BIB (bottle) on top of the coiled

tubing with the connector facing down, under the bag.

b. Under the counter: Place the BIB under the counter and rout the tubing to the dispenser, avoiding sharp

bends and kinks. Cut off excess tubing to keep the over length of tubing to minimum.

NOTE: It is critical that the dispenser is upright and the concentrate container(s) be in the proper location and
orientation that they will be during normal operation, before making any strength adjustments.

10. Slide the dispenser to the edge of the counter to gain access to the adjustment screw from the bottom.

11. Turn the adjustment screw approximately 1/2 turn counterclockwise.

12. Place a container under the faucet(s) and open faucet(s) until the entire concentrate line(s) fill and tea is
dispensed for approximately 5 seconds. Close the faucet(s). Discard this solution.

13. Place a glass under the faucet and open to fill the glass. Adjust the screw to achieve the desired strength
of tea. To increase the amount of concentrate (stronger tea), turn the adjustment screw counterclockwise
slightly (1/16 to 1/8 of a turn at a time). To reduce the amount of concentrate (weaker tea), turn the adjust­ment screw clockwise slightly (1/16 to 1/8 of a turn at a time).

14. Dispense a couple of 8 ounce glasses of tea after each adjustment and test for taste or color. Continue this
process until the taste or color profile is achieved.

NOTE: The ratio adjustment setting is very sensitive. Make very small adjustments with the screw, then taste or
color check the results. You do not have to turn the screw very much to change the ratio.

15. Once the desired ratio of concentrate to water has been set, slide the dispenser back to the desired location
on the counter top. For under counter BIB’s, make sure the tubes do not get kinked, when the dispenser is
slid back into place.

The dispenser is now ready for use.

Daily Cleaning:

1. Turn handle on rear of dispenser to shut off the water supply.

2. Open the faucet to relieve pressure in the system.

3. Since the bag connector(s) have an internal shut off valve, it will be necessary to prop the valve open during clean­ing.

NOTE: Cutting off the mating connector of an empty concentrate bag works well for this. Keep this mating end for future
cleanings of the system.

4. Turn on water supply to the dispenser.

5. Place the open bag connector into a 1/2 gallon container of dish soap and warm to hot water (130° F/54° C).

6. Place a large container under dispenser faucet.

7. Open faucet until the soap/water mixture in the container is empty.

8. After the soap mixture has been flushed through the system, fill the container with warm to hot tap water only (no
soap) and repeat steps 5 thru 7 until all soap has been flushed from the system.

9. Remove the mating end of connector and attach dispenser’s connector to a Bag In a Box and dispense several cups
to prime the concentrate line or until consistency of the product is correct.

10. Wash the entire outside surface of dispenser with a clean, damp cloth.

NOTE: When the system is not in use for extended periods of time (nights, weekends, etc.), turn the water supply valve
off.

Weekly Cleaning:

1. Turn handle on rear of dispenser to shut off the water supply.

2. Open the faucet to relieve pressure in the system.

On models with chrome nut (Complete Step 3, then skip to Step 6):
On models with wing nut (Skip Step 3 - Start at Step 4):

3. Unscrew the faucet bonnet (a) and remove all faucet components, leaving the faucet body (b) in place on the venturi
assembly.

4. Twist the faucet wing nut in a clockwise direction and remove faucet from the dispenser.

5. Remove and clean the O-ring (Optional).

a. Remove the o-ring from the venturi assembly nozzle. Be very careful when removing this o-ring.

Do Not scratch or nick the o-rings sealing surface when removing.

b. Clean the groove and o-ring with the same solutions as used to clean the faucet, Step 6.
c. When finished, slide the o-ring back into the groove on the venturi nozzle.

6. Sanitizing the faucet:

This procedure requires three cleaning solutions of approximately ½ gal each, a mild detergent and warm
water solution, clean hot water only and a warm chlorine solution (at least 50 ppm of chlorine at 75° F [24°
C]). NOTE: DO NOT use full strength bleach.
a. Disassemble the faucet.
b. Thoroughly wash all faucet parts in the mild detergent solution.
c. Rinse the parts in hot water.
d. Sanitize the parts by soaking for one minute in the warm chlorine solution.
e. Re-rinse the parts in hot water to remove all the chlorine solution.
f. Reassemble the faucet and attach it to the dispenser.

7. Sanitizing the BIB connector, tubing and metering valve:

This procedure requires a 1/2 gallon container of sanitizing solution, (100 ppm of chlorine at 100° F (38° C) water).
a. Since the bag connector(s) have an internal shut off valve, it will be necessary to prop the valve open during clean-

ing. NOTE: Cutting off the mating connector of an empty concentrate bag works well for this. Keep this mating end for
future cleanings of the system.

b. Turn on water supply to the dispenser.
c. Place open bag connector into the 1/2 gallon container of sanitizing solution.
d. Place a large container under dispenser faucet.
e. Open faucet until the chlorine mixture in the container is empty.
f. Allow dispenser to sit overnight before flushing sanitizer out of the system.
g. Flush system by filling a container with warm to hot tap water only (no chlorine) and opening the faucet - until all

chlorine has been flushed from the system.

8. Remove the mating end of connector and attach dispenser’s connector to a Bag In a Box and dispense several cups
to prime the concentrate line or until consistency of the product is correct.
