Steam generator deliming should be done on a scheduled basis. The frequency depends on the quality of the local water supply and whether or not a water treatment system is used. Even with the use of a water treatment system, periodic deliming of the steam generator is still required.
On combi ovens using a water treatment system, follow the instructions for that system to delime the steam generator. Only use the type of chemical recommended or described in the deliming instructions for the system in use. If the Kleensteam water treatment system is used, Scalekleen is the recommended chemical.
If a water treatment system is not used, follow the instructions for deliming the steam generator using vinegar, as outlined in the steps below. See “WATER CONDITIONING” under “GENERAL”.
