Chamber rack
Insert the rack into the sterilizer chamber, align it at the center/bottom of the chamber and push it gentl
into position until it clicks.
The chamber rack is reversible and can accommodate 5 tra s horizontall or 3 cassettes verticall .
If inserted in a 90° degree rotated position, the rack holds 3 tra s or 3 cassettes horizontall .
Usable space in the chamber
195 x 195 x 390mm (WxHxD); equal to the volume of 15 litres.
The chamber furniture consists of the tra s, the tra rack and the steam diffuser plate.
Before touching the chamber furniture, ensure the sterilization chamber
is cold: risk of burns!
Sterilit at the end of the c cle is not guaranteed if the steam diffuser plate was not correctl placed.
