Safety Information

Always adhere to standard laboratory safety procedures when operating this equipment. Read all instructions before use.

• Ensure the unit is connected to a properly grounded power supply (220/240 volts, 60 Hz).
• A vacuum pump with a displacement of 144 lpm or larger is required and must be properly connected.
• Do not block ventilation openings on the unit.
• Avoid direct contact with heated or cooled surfaces within the chamber.
• In case of alarm (red LED indicator), consult the troubleshooting section or contact support.

Setup and Installation

1. Placement: Position the dryer on a stable, level surface, ensuring adequate clearance for ventilation.
2. Power Connection: Connect the unit to a 220/240 volts, 60 Hz power outlet.
3. Vacuum Pump Connection: Attach a compatible vacuum pump (144 lpm or larger displacement) to the 3" diameter outlet. Ensure all connections are secure and leak-free.
4. FreeZone System Connection: Connect the dryer to a FreeZone 6, 12, or 18 Liter Freeze Dry System using the provided interconnect cable and RS232 port.
5. Initial Check: Before loading samples, perform a dry run to ensure all systems (refrigeration, heating, vacuum) are functioning correctly.

Operating Instructions

The FreeZone Stoppering Tray Dryer offers precise control over drying and stoppering processes.

Loading Samples

• Open the 3/4" thick acrylic door.
• Place serum bottles or vials onto the three shelves, each measuring 1.6" x 12". Ensure even distribution.
• Close the acrylic door securely.

Programming and Control

• Power On: Activate the power switch on the control panel.
• LCD Display: Monitor system and probe temperatures (in °C or °F), vacuum levels (in mBar, Pa, or Torr), and program segment on the LCD.
• Temperature Control: Use the microprocessor-controlled temperature ramp and hold programming to set temperatures from -40°C to +40°C. The 1000-watt electric heater and 1 HP CFC-free refrigeration system circulate fluid medium through the shelves for precise temperature management.
• Program Storage: The unit can store up to five programs, allowing for repetition of identical protocols.
• Stoppering Control: Once drying is complete, activate the stoppering control knob. This raises the shelves via an expanding diaphragm, stoppering the containers under vacuum.
• Vacuum Release: Use the vacuum release valve control knob to release vacuum after stoppering.
• Backfill Port: Utilize the 1/8" OD backfill port for inert gas backfilling if required.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your tray dryer.

• Cleaning: Clean the brushed stainless steel and epoxy-coated steel exterior with a mild, non-abrasive cleaner. The acrylic door should be cleaned with a soft cloth and a cleaner specifically designed for acrylic to prevent scratching.
• Shelf Inspection: Periodically inspect the shelves for any residue or damage. Clean as necessary.
• Vacuum System: Regularly check vacuum lines and connections for leaks. Ensure the vacuum pump is maintained according to its manufacturer's instructions.
• Probe Calibration: If temperature readings appear inaccurate, consider professional calibration of the temperature probes.
