They are connected to the ice making unit by copper tubing and line valves. The male half of the line valve is mounted qn,tbe ice making unit and the remote condenser. The female half is soldered on the tube ends when tubing kits are provided with the machine.

SANITIZING AND CLEANING PROCEDURE 1. Remove front panel to gain access to the on-off-clean switch. 2. Push switch to "clean" and allow the ice on the evaporator to release or melt away. 3. Remove all ice from storage bin. 4. If lime scale is present add 2 oz. of "Lime-A-Wayn or Yalgon Nickel-Safe Ice Machine Cleaner" directly into water reservoir. Circulate for no longer than 15 minutes. Go to Step 7 to flush out the system before going to Step 5.
