Cleaning and decontamination must be performed by qualified personnel wearing suitable personal protective equipment. Always observe national and local regulations.

NOTICE

Wipe up all liquids spilled onto the system immediately. If surfaces are exposed for longer periods, these liquids can cause damage.

Decontamination

Decontamination is required, for example, when leakage or spillage has occurred, or before service or transport of system modules or system. Use a suitable cleaning detergent or disinfectant to ensure that the treatment renders the system modules or the system safe to handle.

Parts required

  • Suitable cleaning detergent (or disinfectant)

  • Purified water

  • Lint-free cloths or wipes

CAUTION

Explosive Gas Mixtures from Alcoholic Cleaning Detergents

Alcohol-containing cleaning detergents may form flammable and explosive gas mixtures with air.

  • Use such cleaning detergents only when required and only in adequately ventilated rooms.
  • Avoid open flames or exposure to excessive heat during the cleaning process.
  • Wipe the cleaned components thoroughly dry after cleaning. Do not operate the device before it is completely dry.

NOTICE

Observe the following:

  • Only use cleaning detergents that will not damage the surfaces of the system.
  • Never use sharp tools or brushes for cleaning any surfaces.
  • Do not use sprays for cleaning.
  • Prevent cleaning detergent from entering the flow path.
  • Do not use excessively wetted cloth or wipes for cleaning. Prevent any liquids from entering the functional components of the device. Liquids can cause a short circuit when getting in contact with the electronic components.

Preparations

  1. If you want to clean or decontaminate the autosampler or the system only:

  1. Move the needle unit into service position.
  2. Tighten the shipping lock screw (see Securing the Needle Unit).
  3. Remove all sample containers and sample racks from the sample compartment.
  1. Proceed as required:

    • If you want to clean or decontaminate an individual system module: Turn off the power to the system module and disconnect the power cord from the power source.

    • If you want to clean or decontaminate the system: Turn off the power to all system modules and to the system and disconnect the power cords from the power source.

Follow these steps

  1. Wipe the surfaces clean with a clean, dry, soft, lint-free cloth or wipe. If necessary, slightly dampen the cloth or wipe with a solution of lukewarm water and a suitable cleaning detergent.

  2. Allow the cleaning detergent to react as recommended by the manufacturer.

  3. Wipe the cleaned surfaces with purified water to ensure that all cleaning detergent residues have been removed.

  4. Wipe the surfaces dry using a soft, lint-free cloth or wipe.

Post-Cleaning/Decontamination Steps

  1. If you cleaned or decontaminated the autosampler or the system only:

  1. Loosen the shipping lock screw.
  2. Place the sample containers and sample racks in the sample compartment.
  1. Connect the power cord(s) to the power source.

  2. Turn on the power to the system module(s).

    When the autosampler has powered up, the needle unit automatically moves into Inject position.

  3. Prepare the system for operation (see Preparing the System for Operation).
