**Performance is based on 230V, 60
Hz. operation and a 24°C ambient.
For 50 Hz operation, stated
performance and air flow may be
approximately 17% less.
Specifications are subject to change.

**Electrical requirements on
temperature only units. Amperage
may increase on humidity models.
See quotation for actual values.

The performance of your chamber is significantly affected by
the characteristics of your test sample. Factors including size,
material, shape, weight and power dissipation if energized. The
test sample should be placed in the chamber in a manner that
allows proper ventilation. Air flow is from top to bottom in the
chamber. Test samples should be placed on the shelves, not
placed directly on the chamber floor.

Please reference your CSZ quotation as values may vary in
specific chamber performance listed in each chart seen on
pages 14 - 17.
