GENERATOR DELIMING
WARNING:
THE OVEN AND ITS PARTS ARE
HOT. USE CARE WHEN OPERATING, CLEANING
OR SERVICING THE OVEN. THE COOKING
COMPARTMENT CONTAINS LIVE STEAM. STAY
CLEAR WHEN OPENING DOOR.
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”.
