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.
REMOVAL OF LIME SCALE DEPOSITS
About once a week, perform the following procedure to remove lime buildup in the steam generator:
Drain the steam generator by pressing OFF. The steam generator drain pump will operate for
about one minute.
Using the funnel and flexible tube shipped with the oven, carefully pour white vinegar into the
steam generator tank through the inlet-port inside the oven. The inlet port is located on the back
wall, top left corner (some models have two ports). Approximately 1.6 U.S. gallons of vinegar is
required for the 10 level oven; 2.6 U.S. gallons for the 20 level half-depth oven; and 5.3 U.S. gallons
for the 20 level full depth oven. Allow the vinegar to set overnite. In the morning, press ON so that
the steam generator can be flushed. Then press OFF and allow the drain pump to empty the tank.
Carefully flush the steam generator tank and the inside of the oven with fresh water — twice.
Press ON. Operate the oven in Steaming mode for approximately 10 minutes.
Drain the steam generator: Press OFF and allow the steam generator drain pump to operate for
about one minute.
The oven is again ready for use.

MOTORS
Motors are permanently lubricated and require no further lubrication.
