CLEANING & PREVENTATIVE MAINTENANCE
General Cleaning and Sanitizing Procedures
Note:
The BUNN
®
Liquid Coffee Dispenser incorporates a “user selectable” rinse reminder feature, which lights
the Rinse LED on the front panel and disables dispensing when it is time to rinse. See
Programming Functions
to activate this feature.
Daily: RINSING
1. Open the dispenser door.
2. Select
Rinse
on the Function Selector Switch and
Run
on the Mode Selector Switch.
3. Close the dispenser door.
4. Place a 1/2 gal (2 liter) container under the appropriate dispense nozzle or nozzles.
5. Activate the Dispenser of the appropriate side or sides for approximately twenty seconds or until the hot
water is clear or has no concentrate coloring in it.
6. Open the dispenser door, select
Normal
on the Function Selector Switch, and then close door.
Note:
To clear the “Rinse” alarm, activate each dispenser until the flow stops automatically (approx. 20 seconds
for each tip). The “Rinse” alarm LED will turn off when the Rinse Procedure has been satisfied for both sides.
Daily: PARTS WASHING
1. Remove and wash the drip tray, drip tray cover, and cup tray in a mild detergent solution. Rinse
thoroughly.
2. Wipe splash panel, area around dispense nozzles, door, and cabinet with a clean damp cloth.
Weekly: SANITIZING
1. Open the dispenser door.
2. Select
Prime
on the Function Selector Switch and
Run
on the Mode Selector Switch.
3. Remove the bag connector from the product box and disassemble or prop open the internal valve to allow
free flow of product through the connector.
NOTE:
Cutting the mating fittings from an empty bag makes an
excellent “free flowing” connector for this purpose.
4. Place the bag connector into a one-gallon (3.8 liter) container of warm soapy tap water 140°F (60°C).
5. Place an empty container under dispense tip and activate the corresponding Dispenser until the clean soapy
water is dispensed from the dispense tip.
6. Repeat steps 4 and 5 with warm tap water 140°F (60°C) to rinse the soapy water from the pump tubing.
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 4 and 5 with the sanitizing solution. Once sanitizing solution is being dispensed, stop
dispensing and allow the solution to sit for 5 minutes.
9. Repeat step 6 to flush out the sanitizing solution from the pump tubing.
10. Remove the mating connector from the bag connector.
11. Reattach the bag connector to product box.
12. Select

glass of concentrate/water mixture and discard.
