5. HANDLING PRECAUTIONS
Caution

.
DO NOT place items on bottom surface of chamber.
Operating unit with test samples placed directly on bottom surface of chamber may cause unit
to perform poorly. Likewise, chamber temperature may become excessive, causing malfunction
or damage. Always use the supplied chamber racks, supported on the standard supports, and
avoid placing any items on bottom surface. Do not allow test samples to contact chamber walls.
9. Power outages.
In the event of a power loss during operation, one of the following will occur when power is
restored, depending on what settings have been selected:

Continued operation: if power recovery settings have been set to continue (factory
default), pressing START/STOP, after power is restored, will allow operation will pick up
where it left off with the power failure.

Stop operation: if recovery settings have been set to stop, operation will be terminated and
unit will go into idle when power is restored.
See “Recovery Modes” (P.41) for details.
10. Chamber door seal.
Chamber door seals are manufactured from silicon rubber. Benzoic acid, oil, and other
components used during the silicone rubber manufacturing process may be emitted during
operation, spoiling incompatible test samples. If test samples, sensitive to silicone rubber
by-products, are to be processed; specially formulated fluoro-rubber seals are available upon
request.
Note that acids, alkaline, and halogenated solvents are corrosive to rubber.
Substances which cause corrosion or damage to the silicon or fluoro rubber used in chamber door
seals are shown in the Table 5.1.
Do not process test samples which contain any of the substances shown in this table.
For further assistance, contact a Yamato sales office or dealer.
