Optional Components

Model MDF-U537D:The recorder is located on the top of the unit and on the left lower front of the freezer because the upper and lower chamber is controlled independently.

< Attachment of MTR-G85 on the top of the freezer >

1.	Attach the recorder to the mounting kit by following
the procedure shown in the manual enclosed with the
mounting kit.
2. Fix the recorder on the top of the freezer by using 4
screws provided with the mounting kit.
3.	Remove 2 rubber caps (outside and inside) on the
access port on the back of the freezer and also
remove the insulation in the port.
4. Pass the recorder sensor into the chamber through
the access port. See Fig. 10
5.	After covering the recorder sensor with the cover
provided, fix the recorder sensor under the 2nd shelf
by using 2 enclosed binders. See Fig. 11.
6. Make a small cut on the rubber caps for capillary to
pass.
7.	Replace the insulation into the access port and
cover the port completely with the rubber caps.
8. Remove the top cover of the freezer by unscrewing
6 screws. Fig. 12
9.	Join the wire from the freezer and wire from the
recorder by using the enclosed connecting wire.
See Fig. 13.
