5) Remove descaling port cap (see Figure 6-1)
6) Add required amount of Dissolve® through the descale port

Refill can take up to 8 minutes
•
Use 1 gallon Dissolve® for Ultra 5 gas
•
Use 1 ½ gallons Dissolve® for Ultra 10 gas
7) Add 1-2 gallons of cold tap water to descaling port after refill stops; continue to fill with cold water
until descaling solution enters cooking compartment(s) through steam nozzles
•
Note: Some descaling solution will flow from drain of Ultra 10 gas steamers
•
Adding extra water to generator(s) raises descaling solution to higher than normal water fill
level, allowing descaling solution to clean sensors and surfaces above normal water fill level
