Fault Diagnosis

correctly connected to the main unit with the clamp (tightly).
Check that the drain valve is closed.
Check that the sealing ring is installed correctly.
Check that the vacuum pump functions correctly and the vacuum pump oil is clear.
If the error remains, contact the service department. Replacement parts may be required.
Vacuum pump oil leakage| Check that the drain valve is closed, and the chamber is vacuum sealed.
Check the vacuum oil level from the viewing window and confirm it is not excessive.
Check whether the vacuum oil has begun to solidify. If this does occur, change the oil.
Make sure that the temperature inside the chamber is not excessive (>80°C). Wait until the temperature inside the chamber is below 40°C before starting the pump.
The Freeze Dryer chamber isn’t cold| Check the chamber temperature on the HMI screen to make sure that cooling is working.
Check that “Defrost” is not running.
Make sure the compressor is running.
If compressor is “ON” but the temperature inside the chamber is still high, check the air-cooled condenser and to make sure it is not clogged.
| Ensure that there is enough clearance around the vents and that ambient temperature of the room is below 30°C

Cleaning and Maintenance

10.1 Cleaning

• Condensation from the product may precipitate inside of the chamber, please be sure to clean the inside of the chamber periodically by wiping off any the chamber walls.
  Clean the trays after every freeze-drying process with detergent. Wipe dry afterwards.

10.2 Maintenance

• Check the sealing ring regularly to make sure it is not damaged or worn.
• Check the vacuum oil after every 100-hours of operation and replace the vacuum pump oil if the level is low or the oil is dirty.

Terms Explained

• Prefreeze Time: When the “Frozen product” option is switched “OFF” in the Recipe Selector page (Figure 33), meaning the product is not frozen, the program will start cooling the product once the auto-drying program starts. The program will move to the next stage (Evacuation stage) only when the shelf temperature has been lower than the Prefreeze Temp for the duration set in the Prefreeze Time.

• Prefreeze Temp: This is the temperature which the shelves will cool down to when the ‘Frozen product’ option is switched ‘OFF’. This value should be below the expected freezing temperature of your product. See Prefreeze Time for additional information.

• Evacuation Time: Evacuation Time and Vacuum are used to control the evacuation stage. The program will turn the vacuum pump on when the evacuation stage begins.
  The program will progress to the next stage, the drying stage, when the chamber pressure has been lower than the pressure set in Vacuum for the duration set in the Evacuation Time.

• Vacuum: see Evacuation Time.

• Vacuum High Limit: When the chamber pressure is higher than the Vacuum High Limit or lower than the Vacuum Low Limit, the program will display a warning. The warning will be removed once the chamber pressure returns to normal (within the set boundaries).

• Vacuum Low Limit: see Vacuum High Limit.

• 

• Vacuum Hbysteresis: Vacuum Hysteresis is used as the maximum allowable overshoot of the chamber pressure when the chamber pressure is controlled by the program via the vacuum valve. During each drying step, the range of the chamber pressure is between the current step’s target Vacuum – 5Pa and the target Vacuum + Vacuum Hysteresis. For example, if the current step has a target Vacuum of 100Pa and a Vacuum Hysteresis of 20Pa, the actual chamber pressure will range from 95Pa (100Pa – 5Pa) to 120Pa (100Pa + 20Pa). If the chamber pressure exceeds the upper limit, the program will open the valve, allowing the pump to suck air out and lowering the pressure inside the chamber. If the chamber pressure drops below the lower limit, the program will close the valve to stop the air flow. 

• Process End Temperature: Process End Temperature and Process End Pressure are used to hold the machine until an operator makes any changes once the drying program is completed.

• Process End Pressure: see Process End Temperature.

• Maximum Shelf Temperature: Maximum Shelf Temperature is a safety limit to prevent the shelves from reaching a temperature which may damage the product.

Removing/Installing Shelf Stack

Step 1

• Open the chamber door and confirm there is no ice build-up that will prevent removing the shelf stack. Carefully pull out the shelf stack.
• Place the stack on the table next to the freeze dryer (see Figure 38). Ensure the connecting cable is not strained. (See Figure 38)

Step 2

• Locate the plug assembly and press the release tabs to unplug the shelf stack from the freeze dryer. (See Figure 39)

Step 3

• When installing the shelf stack, identify the top and bottom of the plug before attempting to plug it in. Make sure to remove any moisture from the connection points.
• Figure 40 and Figure 41 demonstrate the male plug.
• Figure 42 demonstrates the inside of a male plug.
• Figure 43 demonstrates the female plug.

Step 4

• When reinstalling the shelf stack, ensure the connecting cable is not coiled underneath as in Figure 44.

Step 5

• When reinstalling the shelf stack, gently push the shelving stacks halfway and ensure the connecting cable is behind the shelf stack, in a coiled format, so as to not affect the ice condensers efficiency (see Figure 45 and 46).
