CARE AND CLEANING

The range should be thoroughly cleaned at least once a week in addition to the normal daily cleaning to
insure against the accumulation of foreign material.  Keep inside of oven and metal deck clean, particularly
around door opening, door edges and at bottom of door opening so that the door may close tightly.
CAUTION:  ANY OVEN CLEANER USED SHOULD BE MARKED:  "SAFE ON ALUMINUM".

Keep-drip pans under range top plates clean.

Keep hotplate and griddle surfaces clean.

Outside of range and top should be kept clean.

Electric equipment is inherently clean and sanitary, but may become unsanitary if dirt is allowed to
accumulate on it.  Take advantage of the clean, sanitary features of electric equipment, give it the regular
attention that it deserves, the same as any other highly perfected machinery, to insure best results and
continued high operating efficiency

!

Note cycle on temperatures and cycle off temperatures for 3 cycles (Red indicator light indicates when
oven is calling for heat).

!

After 3 cycles average the temperature ( Add all six temperatures and divide by 6).

Calibration Adjustment
