2. Інформація про безпеку

Always adhere to standard laboratory safety practices when operating this equipment. Read and understand all instructions before use. Failure to do so may result in injury or damage to the equipment.

• Ensure the unit is connected to a properly grounded electrical outlet (115V, 60 Hz).
• Не використовуйте систему з пошкодженими шнурами або вилками.
• Always wear appropriate personal protective equipment (PPE), such as safety glasses and gloves, when handling samples or performing maintenance.
• Avoid contact with cold surfaces, as the collector coil reaches temperatures as low as -50°C (-58°F).
• Забезпечте належну вентиляцію навколо пристрою, щоб запобігти перегріву.
• Не блокуйте вентиляційні отвори.
• Only use the system for its intended purpose of freeze drying.
• Від’єднайте живлення перед виконанням будь-якого технічного обслуговування або ремонту.

3. Налаштування

Proper setup is crucial for optimal performance and safety. The FreeZone system requires a separate vacuum pump, drying accessory, and freeze dry glassware, which are not included and must be acquired separately.

1. Розміщення: Position the freeze dry system on a stable, level benchtop or cart. Ensure there is sufficient space around the unit for ventilation and access. The compact design allows it to fit in tight spaces.
2. Електричне підключення: Connect the system to a dedicated 115V, 60 Hz grounded electrical outlet.
3. Vacuum Pump Connection: Connect your external vacuum pump to the system using the provided 3 feet of 3/4 inch ID vacuum hose and 2 clamps. Ensure all connections are secure to maintain vacuum integrity.
4. Додаткове кріплення: Utilize the 3-inch diameter accessory attachment port for connecting your drying accessory and glassware.

4. Інструкція з експлуатації

The FreeZone system is designed for user-friendly operation with automated features and manual overrides.

1. Увімкнення: Locate the power switch and turn the unit on.
2. Automatic Start-up: The system features a one-button automatic refrigeration and vacuum start-up. Press the designated button to initiate the cooling of the collector and the pull-down of the vacuum.
3. Manual Overrides: Manual override switches are available for independent control of refrigeration and vacuum functions, allowing for greater flexibility in specific applications.
4. Моніторинг: The LCD display provides real-time information on set-up and operating parameters. It also displays alarm messages and the total number of hours since refrigeration and vacuum were last serviced.
5. Vacuum Control and Break Valve: Utilize the integrated vacuum control and break valve to manage the vacuum level during the freeze-drying process.
6. Датчик вологи: The patented moisture sensor helps detect moisture in the collector, providing an early warning for potential issues.
7. Sample Loading: Once the collector has reached its target temperature (-50°C) and the vacuum is established, attach your freeze-dry glassware containing the pre-frozen samples to the accessory attachment port.

5. Технічне обслуговування

Regular maintenance ensures the longevity and optimal performance of your freeze dry system.

• Розморожування: The upright stainless steel collector coil can hold up to 2.5 liters of ice. Defrost the collector when necessary, typically after 2 liters of water have been removed or when ice buildup impedes performance. Use the collector drain hose for convenient drainage of melted ice.
• Vacuum Pump Service: The LCD display tracks the total number of hours since the vacuum pump was serviced. Refer to your vacuum pump's manual for its specific maintenance schedule, including oil changes and filter replacements.
• Refrigeration System Service: The LCD display also tracks the total number of hours since the refrigeration system was serviced. While routine user service is minimal, professional service may be required if performance degrades.
• Прибирання: Clean the exterior of the unit with a mild detergent and a soft cloth. Avoid abrasive cleaners or solvents.
• Огляд: Periodically inspect the vacuum hose and clamps for any signs of wear or damage. Replace as needed to maintain vacuum integrity.

6. Вирішення проблем

The system is equipped with an audible/visual alarm system to alert you to abnormal events. Consult the LCD display for specific alarm messages.
