Freeze dryer maintenance:
1. Be careful to remove moisture from the cold trap chamber before working. Dry the cold trap if necessary. It is recommended to open the drain valve before each freeze-drying operation, freeze the dryer and then turn it off.
2. Do not switch frequently during use. If the chiller stops running due to operational errors, it cannot be started immediately. Wait at least 20 minutes before starting again to avoid damage to the chiller.
3. After each freeze-drying, the ice on the cold trap coil is turned into water, and then cleaned with a towel. After the freeze-drying is completed, the "inflator valve" is inflated to the cold trap, so it must be slow to avoid damaging the vacuum gauge.
4. Regularly check the liquefier at the bottom of the machine for dust and dirt and clean it if necessary. When checking the heat exchanger, tilt the chassis over the cushion. The high pressure air purged heat exchanger can be used as appropriate. Excessive liquefaction can increase power consumption and even damage the machine.
5. Should be avoided to use without load.
6. The freeze dryer switch should avoid continuous switching to avoid over-loading.
