*** Antibacterial silver stainless steel ***
In this unit antibacterial silver stainless 
steel is used as the material of interior.
Antibacterial silver stainless steel has high 
antibacterial spectrum at 99% or more in 
multiple screening test of antibacterial 
effective (Film coherent method).
The effect is also shown in our sampling 
test of chamber air to be beneficial for 
antibacterial ability.

Bracket holder, brackets and a part of 
chamber interior is not made of 
antibacterial silver stainless steel.

2. Cleaning the chamber

3. Cleaning of refrigeration unit filter

The operation with the clogged filter 
worsens the cooling performance.
Also, some troubles are caused on the 
refrigeration unit.
Clean the filter on a regular schedule 
depending on environmental or operating 
condition.

The filter is attached at inside of the 
ventilation port.
Hold the left edge of the ventilation cover 
with your hand, and pull it open.
