8.2 Product Returns
Should you need to return your Excella E-24/24R to Eppendorf for any reason, first
contact Customer Service to obtain a Returned Material Authorization (RMA) number.
This number must appear on the outside of the shipping container, otherwise Eppendorf
Receiving will refuse to accept the shipment.
In addition, you must also certify that the instrument being returned has been thoroughly
cleaned and decontaminated. A form for this purpose is provided in Section 12 of this
manual; it can also be downloaded from our website (
www.nbsc.com ). A copy of this
completed Return Authorization and Decontamination Certificate must be attached to the
outside of the container, with a second copy packed inside with the instrument.
8.3 Opening the Service Compartment
WARNING!
Before opening the Service Compartment, always turn off the shaker and
disconnect the power cord from the power supply.
The Service Compartment contains the shaker’s electronic and temperature control
components. Normally, this compartment should be accessed by authorized service
technicians only. You may, from time to time, need to remove the access panel in order
to replace fuses (see Section 8.4 below).
