General Cleaning and Sanitizing Procedures
Note:
The BUNN® Liquid Coffee Dispenser incorporates a “user selectable” rinse reminder feature and can be
set to disable dispensing when it is time to rinse. See
Programming Functions
to activate this feature.
Daily: RINSING & CLEANING
1. Select
RINSE
on the Function Selector Switch.
2. Place a 1/2 gal (2 liter) container under the dispense nozzle.
3. Press and Hold any flavor selection switch for approximately twenty seconds or until the hot water is clear
or has no concentrate coloring in it.
4. Wipe splash panels, dispense nozzle, door, and cabinet with a clean sanitary cloth.
Note:
To clear the “Rinse” alarm, activate the dispenser until the flow stops automatically (approx. 20 seconds).
The “Rinse” alarm display will turn off when the Rinse Procedure has been satisfied.
Weekly: SANITIZING
1. Select
PRIME
on the Function Selector Switch and open the dispenser door.
2. Remove the bag connector from the product BIB and disassemble or prop open the internal valve to allow
flow of product through the connector.
NOTE:
Cutting the mating fittings from an empty bag makes an excellent “free flowing” connector for this
purpose.
3. Place the bag connector into a one-gallon (3.8 liter) container of warm soapy tap water 140°F (60°C).
4. Place an empty container under dispense tip and activate the corresponding pump until the clean soapy water
is dispensed from the dispense tip.
5. Repeat steps 3 and 4 with warm tap water 140°F (60°C) to rinse the soapy water from the pump tubing.
6. Continue dispensing until the water is clear, and no soapy water is being dispensed.
7. Prepare 2.5 gallons (9.46L) of sanitizing solution by dissolving 1 packet of Kay 5 sanitizer into 2.5 gallons
(9.46L) of 120°F (48.9°C) water to ensure 100 ppm of available chlorine.
8. Again, repeat steps 3 and 4 with the sanitizing solution. Once sanitizing solution is visible, continue to dispense
for 1 minute. Release handle and allow solution to sit for 5 minutes.
9. After soaking for 5 minutes, activate the dispense switch a second time, this time for 2 minutes. After 2
minutes, release the dispense switch.
10. Repeat steps 5 & 6 wit warm tap water to flush out the sanitizing solution from the pump tubing.
11. Reattach the bag connector to product BIB.
12. Close the dispenser door and select
NORMAL
on the Function Selector Switch.
13. Activate the dispenser until concentrate/water mixture appears. Then dispense 20 ounces (600 ml) container
of concentrate/water mixture and discard.
14. Repeat steps 1 through 13 for other two Pumps.
15. Wipe internal and external surfaces with a clean, sanitary cloth.
Weekly: REFRIGERATION AIR FILTER
1. Remove the screen filter from the bottom of the dispenser.
2. Wash the screen in a mild detergent solution.
3. Use a soft bristled brush to remove all dust and grease.
