Maintenance and Diagnostics

9.3 Fuse replacement

The following illustration shows the position of the fuse, which is located next to the mains
connectors on the power supply board under the shielding plate.

Two replacement fuses are supplied with the instrument and these must be used to replace
faulty or blown fuses.

If for any reason these replacements are no longer available, only the following alternatives
should be used:

JDYX2, LITEFUSE, type 213, rated 2 AT, 250 VAC

JDYX2, SIBA, Type 179120, rated 2 AT, 250 VAC

JDYX2, SCHURTER, Type FST, rated 2 AT, 250 VAC

If there is any difficulty in obtaining these replacement fuses, please contact your local Hach
Lange representative for advice and assistance.

9.4 Cleaning and decontamination

The analyzer does not normally require any cleaning or decontamination. The internal cycle is
only in contact with clean, pure water.

If needed, clean the exterior of the instrument with a moist cloth and a mild soap solution. Never
use cleaning agents such as turpentine, acetone or similar products to clean the instrument,
including the display and any accessories.
