General Cleaning and Sanitizing Procedures
Note: The BUNN
®
LCA-2 LP dispenser incorporates a “user selectable” rinse reminder feature, which lights the
Rinse LED on the front panel when it is time to rinse. See Programming Functions to activate this feature.
Daily: RINSING
1. Open the dispenser door and set the Function Switch to Rinse and the Mode Selector Switch to RUN.
2. Close the dispenser door and place a 1/2 gal (2 liter) container under the dispense nozzle area.
3. Activate both dispense switches until the water is clear or has no concentrate coloring in it, (10 to 20
sec.).
4. Open the dispenser door, set the Function Switch back to Normal.
Note: To clear the “Rinse” warning, activate both dispense switches (one at a time) until the flow stops automatically
(approximately 20 sec. for each tip). The “Rinse” LED will turn off when the Rinse time has been satisfied.
Daily: PARTS WASHING
1. Remove and wash the drip tray and drip tray cover in a mild detergent solution. Rinse thoroughly.
2. Wipe the splash panel, dispense nozzles, door, and cabinet with a clean damp cloth.
Weekly: SANITIZING
1. Open dispenser door and select Prime on the Function Selector Switch and Run on the Mode Selector
Switch.
2. Remove 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.
3. Place bag connector into a one gallon (3.8 liter) container of warm soapy tap water 140F (60C).
4. Place an empty container under dispense tip and activate corresponding Dispense Switch until clean soapy
water is dispensed from the dispense tip.
5. Repeat steps 3 and 4 with warm tap water 140F (60C) to rinse the soapy water from the pump tubing. Con-
tinue activating Dispense Switch until water is clear, and no soapy water is being dispensed.
6. Prepare 2.5 gallons (9.5L) of sanitizing solution by dissolving 1 packet of Kay 5 sanitizer into 2.5 gallons
(9.5L) of 120F (48.9C) water to ensure 100 ppm of available chlorine.
7. 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.
8. After soaking for 5 minutes, activate the dispense switch a second time, this time for 2 minutes. After 2
minutes, release the dispense switch.
9. Repeat step 5 with warm tap water to flush sanitizing solution out of the pump tubing.
10. Remove mating connector from the bag connector.
11. Reattach bag connector to product box.
12. Select Normal on Function Selector Switch and Run on Mode Selector Switch.
13. Actuate Dispense Switch until concentrate/water mixture appears. Continue to dispense at least 12 oz. (355
ml) of concentrate/water mixture and discard.
14. Repeat steps 1 through 13 for other dispense head.
