ROUTINE MAINTENANCE
Defrosting the chamber
Frost may build up in the upper portion of the chamber and the inner door. Excessive accumulation of
frost is likely to create gaps between the cabinet and the magnetic door gasket, which can reduce the
cooling performance. Remove the frost from the chamber and the inner door with the scraper enclosed
with the unit. Use the following procedure for defrosting when excessive frost builds up in the chamber.
Note:
Do not use tool with a sharp edge (such as a knife or screw-driver) to remove the frost.
1. Turn off the switch for the back-up cooling kit (if installed).
2. Take out all contents from the freezer and transfer them
to another freezer or a container which is refrigerated by
liquid carbon dioxide or dry ice.
3. Turn off the power switch and the battery switch of the
freezer.
4. Open the outer door and inner door. Remove the inner
door by lifting it up as shown in the figure.
5. Leave the freezer in this state until the frost in the
chamber melts.
6. Wipe up the water that accumulates at the bottom of the
chamber with a dry cloth.
7. After cleaning the chamber, replace the inner door and start up the unit according to the procedure on
page 17.
8. Check that the chamber temperature reaches the set temperature and then replace the contents.
9. Turn on the switch for the back-up cooling kit (if installed).
