3. Setup Instructions
Proper preparation of the cooling elements is crucial for optimal performance.
3.1 Preparing the Bio-gels

3.2 Assembling the Cooler
- Once the bio-gels are frozen, insert the desired number of bio-gels into the cooler's inner compartment.
- Place your insulin pens or other medications into the provided medicine bags. This isolates the medication from direct contact with the bio-gels, preventing freezing.
- Carefully insert the medicine bags with your medication into the cooler, arranging them around the bio-gels.
- Securely close the cooler lid.

4. Operating Instructions
4.1 Cooling Methods and Duration
The SECRETSBOX 42H offers two primary cooling methods:
- Bio-gel Cooling: For extended cooling, use the frozen bio-gels. The duration of cooling depends on the number of bio-gels used and the external ambient temperature. Refer to the performance chart below for estimated cooling times.
- Emergency Cooling (Ice Bucket): In situations where bio-gels are not available or frozen, you can use the included ice bucket. Fill the ice bucket with ice cubes or cold water and place your medication (in a medicine bag) into the separate compartment. This method can sustain cooling for approximately 6-8 hours, maintaining temperatures between 2-8 °C (36-46 °F).

4.2 Medication Storage Capacity
The cooler's capacity for insulin pens or vials is adjustable based on the number of bio-gels used:
- With 1 Bio-gel: Can hold approximately 8-9 insulin pens.
- With 2 Bio-gels: Can hold approximately 6-7 insulin pens.
- With 3 Bio-gels: Can hold approximately 4 insulin pens.
The cooler is designed to accommodate various types of insulin pens and vials. Always ensure your medication is securely placed within the medicine bags to prevent direct contact with the cooling elements.

5. Maintenance
5.1 Cleaning
- Wipe the interior and exterior of the stainless steel bottle with a damp cloth and mild detergent.
- Rinse thoroughly and allow to air dry completely before storage.
- The bio-gels and medicine bags can be cleaned with a damp cloth. Do not submerge bio-gels in water.
- Do not use abrasive cleaners or harsh chemicals, as these may damage the product.
5.2 Storage
Store the cooler in a cool, dry place when not in use. Ensure all components are dry before storing to prevent mold or mildew.
6. Troubleshooting
If you experience any issues with your SECRETSBOX 42H Insulin Pens Cooler, consider the following:
- Insufficient Cooling: Ensure bio-gels were frozen for the recommended 6-8 hours. Verify the cooler lid is securely closed. High ambient temperatures can reduce cooling duration.
- Medication Freezing: Always use the provided medicine bags to create a barrier between the medication and the frozen bio-gels. This prevents direct contact and potential freezing.
