cheeSe MelteR 18 P/N 1010983 Rev B 05/08 Maintenance (continued) flushing and cleaning Water solenoid The Cheese Melter can be programmed to provide a much larger volume of water per shot to flush and clean the Solenoid Base. note: based on the water conditions in your area, the Water solenoid should be flushed and cleaned at the same time as when cleaning the steam generator. this procedure should be performed monthly but could be done weekly or daily. To perform the Water Solenoid flushing and clean- ing on the Cheese Melter, you have to re-program the shot time on the Operating Button #1. The standard SHOT setting is 0.21 seconds. 1. Follow the programming instruction in the Owner’s Manual to change the shot setting to 2.5 seconds. This is the maximum time that can be programmed. 2. Make sure the unit is up to operating tem- perature. 3. Run one cycle using the button highlighted below. The longer SHOT time will generate a larger volume of water flowing through the solenoid. This increased volume of water will flush and clean the Water Solenoid Base. note: this volume of water will flood the casting. checking and cleaning Water strainer To ensure proper and consistent steaming results, inspect the water pressure regulator gauge and strainer cup regularly. If the water pressure on the gauge has dropped, visually check the clear plastic strainer cup and clean out the accumulated debris as follows: 1. Shut off the water supply valve to the unit. Unscrew the clear plastic strainer cup and carefully remove the mesh strainer screen. 2. At the sink, gently flush all of the accumu- lated debris from the strainer cup and mesh strainer screen. Be especially careful not to damage the mesh strainer screen. 3. Carefully place the mesh strainer screen into its seat at the bottom of the clear plastic cup and confirm that the orange O-ring is prop- erly seated in its place before screwing the strainer cup and top back together. 4. Purge the air out of the strainer tubing by disconnecting the male quick disconnect fit- ting from the equipment and, over a bucket, pushing its valve core in until there is a good water flow. 4. When the cycle is completed, you may want to run a second cycle. Wait until all of the water has turned to steam before using the unit or turning it off. note: re-program the water sHot back to its previous setting.
