CLEANING/SANITIZING PROCEDURE QC700/QF800/QF2300

Use Ice machine cleaner part number 000000084. Use Ice machine sanitizer part number 94-0565-3.

Step 1 Remove front and top covers and set the toggle switch to the OFF position.

Step 2 Remove all ice from the bin.

Step 3 Disconnect water supply line at float valve quick disconnect by depressing stainless steel lever.

Step 4 Remove the top cover from water reservoir.

Step 5 Remove the water level probes from the top cover and with the wires attached, place the water level probes (stand upright) inside the water reservoir.

Step 6 Follow the chart and premix cleaner and water.

Amount of Water	Amount of Cleaner
	Part Number 000000084
1 gallon (3.8 Liters)	3 ounces (90 ml)

Step 7 To start cleaning, move the toggle switch to the ICE position.

Step 8 Wait about 45 seconds until the dump valve light de-energizes. Fill the evaporator and reservoir with cleaning solution. The ice machine will make ice with the cleaning solution and deposit the ice in the bin. Add the remaining cleaner/water solution when the water level in the reservoir drops.

NOTE: Do not allow the water level to drop below the water level probes. The ice machine will discontinue the cycle when the water level probes open (lose water contact) for more than 30 seconds.

Step 9 After all of the cleaner/water solution has been added reconnect the water supply line to the float valve. Continue the freeze cycle for 10 minutes to remove the cleaning solution from the water circuit.

Step 10 Place the toggle switch in the Off position.

Step 11 Disassemble the ice machine and hand clean all parts (refer to disassembly for cleaning/sanitizing).

Step 12 Hand sanitize all parts (refer to disassembly for cleaning/sanitizing for procedure).

Step 13 Remove and discard all ice produced during the cleaning process.

Step 17 Remove the water level probes from the top cover and with the wires attached, place the water level probes (stand upright) inside the water reservoir.

Step 18 Refer to chart and premix water and sanitizer.

Amount of Water	Amount of Sanitizer
6 Gallons (23L) Cool Water	4 ounces (120 ml)

Step 19 To start sanitizing, move the toggle switch to the ICE position.

Step 20 Wait about 45 seconds until the dump valve light de-energizes. Fill the evaporator and reservoir with sanitizer/water solution. The ice machine will make ice with the sanitizer/water solution and deposit the ice in the bin. Add the remaining sanitizer/water solution when the water level in the reservoir drops.

NOTE: Do not allow the water level to drop below the water level probes. The ice machine will discontinue the cycle when the water level probes open (lose water contact) for more than 30 seconds.

Step 21 After all of the sanitizer/water solution has been added to the reservoir, reconnect the water supply line at the float valve quick disconnect.

Continue the sanitize cycle for 10 minutes to remove the sanitizing solution from the water circuit.

Step 22 Place the toggle switch in the Off position, then disassemble the ice machine and hand sanitize all parts (refer to disassembly for cleaning/sanitizing for procedure).

Step 23 Remove and discard all ice produced in the sanitizing process, then reassemble the ice machine and reconnect the water supply.

Step 14 Reassemble ice machine.

Step 15 Disconnect water supply line at float valve quick disconnect by depressing stainless steel lever.

Step 16 Remove the top cover from water reservoir.
