4. Setup and Installation

Follow these steps to properly install the BrandTech 2704838 adapter with your bottle and dispenser:

1. Prepare the Bottle: Ensure the bottle you intend to use has a 33mm neck thread and is clean and dry.
2. Attach Adapter to Bottle: Carefully screw the 33mm threaded end of the adapter onto the neck of the bottle. Turn clockwise until it is hand-tight and secure. Do not overtighten, as this may damage the adapter or bottle.
3. Prepare the Dispenser: Ensure your Dispensette III or Dispensette Organic Bottletop dispenser is clean and ready for attachment.
4. Attach Dispenser to Adapter: Insert the STJ 24/40 joint of the dispenser into the corresponding opening on the adapter. Gently push and twist until a secure fit is achieved. The adapter is designed to provide a stable connection for the dispenser.
5. Verify Connection: Once assembled, gently tug on the dispenser to ensure it is firmly seated and there is no wobbling. A secure connection is vital for safe operation.

5. Operating Instructions

The adapter itself does not have operational controls. Its function is to provide a secure interface. Operation of the dispensing system relies on the proper use of the connected Dispensette III or Dispensette Organic Bottletop dispenser. Refer to the specific user manual for your dispenser for detailed operating instructions, including priming, volume setting, and dispensing procedures.

Key considerations when operating with the adapter:

• Always ensure the adapter remains securely attached to both the bottle and the dispenser throughout the dispensing process.
• Avoid applying excessive force or torque to the adapter during dispensing, as this could compromise the seal.
• If any leakage is observed around the adapter, immediately stop dispensing, check the connections, and re-secure or replace the adapter if necessary.

6. Maintenance and Cleaning

Regular cleaning and proper maintenance will extend the lifespan of your BrandTech 2704838 adapter.

• Cleaning: After each use, especially when dispensing corrosive or sticky liquids, detach the adapter from both the bottle and the dispenser. Rinse the adapter thoroughly with distilled water. For more stubborn residues, a mild laboratory detergent can be used, followed by a thorough rinse.
• Drying: Allow the adapter to air dry completely or wipe it with a clean, lint-free cloth before storage or re-use.
• Inspection: Periodically inspect the threads and the joint area for any signs of wear, cracks, or chemical degradation. Polypropylene is highly resistant, but extreme conditions or improper handling can cause damage.
• Storage: Store the adapter in a clean, dry place, away from direct sunlight and extreme temperatures, to prevent material degradation.
