Maintenance
deliming
Deliming of the steam generator is the single most im-
portant preventative maintenance task. Lime will build up
inside the steam generator, reducing efficiency and caus-
ing damage to the boiler.
WaRnInG!!
Problems caused by insufficient deliming are
not covered by the warranty.
WaRnInG!!
deliming solutions are hazardous and can
cause burns to the skin and eyes. Wear pro-

This control comes equipped with a delime lamp to in-
dicate when the steam generator needs to be delimed.
The delime lamp will flash when the steam generator has
been run for the preset interval. This is a warning only,
the oven can be used all day before deliming. The delime
sequence can be run at anytime regardless of the flashing
delime indicator.

NOTE: Once the deliming process has been started, the
oven cannot be used until deliming is complete,
approximately 45 minutes.
