Environmental Conditions

CAUTIONS FOR USAGE

1.This unit is not explode-proof construction. Never store the materials which cause flammable or volatile gas and never store the flammable or volatile liquid in the unit.

2.The door glass, inside door panel, and exhaust vent are very hot when the unit is used with high temperature setting. Never touch such portion directly with the hands.

3.Avoid to open the door when the chamber temperature is more than 100°C as it is dangerous. The door opening may cause ignition of flammable material or break of equipment resulting from sudden temperature change.

4.Do not block the air intake vent on the chamber floor by the stocked articles. The blockage can cause unstable chamber temperature and shorten the heater life.

5.When cleaning, do not use brushes, acids, benzine, thinner, soap, cleaner or hot water. These will cause discoloring or damage to coated surfaces. On plastic or rubber parts, they will cause transformation, discoloration or degeneration. Never apply volatile chemicals (like benzine etc.) on plastic or rubber parts. When neutral detergent is used, be sure to wipe it up thoroughly with a wet cloth afterwards. Before cleaning the box, refer to page 18.

6.When placing objects inside, remove traces of water as much as possible.

7.When stacking the unit, always use stacking kit available as an optional component.
