COMBITHERM® CLEANING & MAINTENANCE ELECTRIC COMBITHERM DECALCIFICATION Decalcification — ELECTRIC It is VERY important to decalcify the oven, particularly in areas with extremely hard water. PERFORM ONCE A MONTH in addition to the daily steam generator flush. WITH THE OVEN AT ROOM TEMPERATURE 1. Begin decalcification with the power switch in the OFF position. 2. Rotate the Steam Generator Drain Cap until water begins to flow from the four holes in the cap.
COMBITHERM® CLEANING & MAINTENANCE ELECTRIC COMBITHERM DECALCIFICATION PRESS THE ON/OFF POWER KEY TO THE ON POSITION. THE WATER IN THE STEAM GENERATOR WILL BEGIN TO HEAT. ALLOW THE OVEN TO REMAIN IN THIS POSITION FOR A MINIMUM PERIOD OF 10 MINUTES TO DECALCIFY THE STEAM GENERATOR. In the case of extreme calcification build-up such as in areas with very hard water, ovens can be left in this condition overnight. Follow the remaining instructions at the start of the next production day.
