19.2 Checking the air jacket heating fan
The user should regularly perform the following checks:
When the chamber is operating, you will be able to observe the air jacket heating fan centered at the top
of the chamber by looking through the ventilation slides at the rear. During chamber operation, the fan
must turn counter-clockwise continuously. For better monitoring, you can turn off the chamber and wait
until the fan has stopped.
19.3 Checking the humidity system fan
The user should regularly perform the following checks:
Hold a sheet of paper in front of the ventilation silts at the bottom rear of the chamber. If the sheet of
paper is suctioned inwards, the fan operates correctly. When opening the door, the fan automatically
turns off.
19.4 Gas inlet fine filter
When the chamber is in operation, the incoming gas passes through a fine gas filter (aseptic filter,
filtration efficiency 99.99 %, particle size 0.45 µm).This fine filter prevents dirt accumulating in the gas
inlet valves and the tubes leading into the inner chamber, which could be in the gas cylinder or in the
supply tubes.
When using gas with a technical grade of 99.5 %, we recommend changing the fine gas filter once a year.
Please consult BINDER Service. When using gases with less pureness, the changing intervals should be
shorter.
19.5 Sending the chamber back to BINDER GmbH
If you return a BINDER product to us for repair or any other reason, we will only accept the product upon
presentation of an authorization number (RMA number) that has previously been issued to you. An
authorization number will be issued after receiving your complaint either in writing or by telephone prior
to your sending the BINDER product back to us. The authorization number will be issued following receipt
of the information below:
• BINDER product type and serial number
• Date of purchase
• Name and address of the dealer from which you bought the BINDER product
• Exact description of the defect or fault

• Exact location of the BINDER product in your facility
• A contamination clearance certificate (chap. 25) must be faxed in advance
The authorization number must be applied to the packaging in such a way that it can be easily recognized
or be recorded clearly in the delivery documents.
For security reasons we cannot accept a chamber delivery if it does not carry an authorization
number.
