to OFF.
3. Open both doors to the cooking compartments.
4. Set the TIMED/MANUAL switches to TIMED.
5. Set the ON/OFF switch to the OFF position. (The Unit will
undergo a normal blowdown cycle, which Should take
approximately 3 minutes to complete).
6. When the unit has completed draining
,
turn the ON/OFF
switch to ON to refill the unit. Do not start the timer. Leave
the doors open.
NOTE: Be ready to pour in the descaling solution when the power is turned ON.

overflow.
