PERIODIC MAINTENANCE
1. If the oven fails to maintain set temperature,
it may indicate a problem with the Temp.
Control, or possibly a heating element failure.
Contact your local service representative.
2. Gaskets should be checked periodically for
hardening, shrinking, deterioration or other
signs of wear. It is advisable to keep several
gaskets available for use as replacements.
3. The oven is equipped with silicone door
gaskets, unless specified otherwise. Do not
use silicone door gaskets or vacuum grease
when evaporating solvents in the oven or
when using high analine point oils. BUNA-N
gaskets should be used in applications when
evaporating solvents or when using high
analine point oils.
