Care And Cleaning - Lang S13827B Service Manual

CARE AND CLEANING

The oven 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".
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.
CALIBRATION
Calibration Check

! Set thermostat to 350° and place both 3-heat switches in the "HIGH" position.
! Allow the oven to Preheat for at least half an hour.
! Note cycle on temperatures and cycle off temperatures for 3 cycles (Red indicator light indicates when
oven is calling for heat).

Calibration Adjustment
! A 1/16" flat blade screwdriver with a 2" shaft is required to make adjustments on the thermostat.
