This chapter provides basic maintenance tasks that can be performed by an operator. Please contact your local Hitachi Chemical
Diagnostics service representative for information and assistance in performing any other corrective maintenance procedures on the
AP3600 system.

Cleaning and Decontamination

Perform the following steps to clean and decontaminate the AP3600 system.
1. Prepare a 10% bleach solution by using 100 ml of household bleach and adding 900 ml of DI water. This solution must be made and
used within 12 hours of decontamination.
2. Aliquot 25 ml of the 10% bleach solution into the specified or supplied diluent and antibody reagent containers. The Photoreagent
containers should remain filled with DI water. Attach antibody (with 10% bleach solution) and both Photoreagents
(with DI water) to the instrument.
3. Replace the main DI water container with the 10% bleach solution (separate container). Place the wash buffer line into the main
DI water container.
4. Perform one (1) rinse cycle (see Figure D-1). Allow the solution to stay in the lines for ten (10) minutes.

DI water. Replace Waste Container with sampling container #1.
7. Perform one rinse cycle.
8. Sample waste from sampling container #1. Perform strip testing to determine total chlorine content.
