●
Do not subject to direct air flow
Do not allow the air for air conditioning to hit the unit or door directly. Direct hit may cause condensation
or contamination.

Tray
Make sure to set the bottom tray to the bottom position of side duct with tray support. This may cause
condensation on bottom cover by varying air flow inside chamber.
●
Do not block holes on the side duct with the culture vessels.
When storing cultures in the chamber, take care not to block holes on the side duct with the Petri dishes
or roller-bottle racks to allow adequate air circulation. Blockage of holes may result in uneven
temperature distribution and CO
