For Safe Use of the Product
1
Since this product is not constructed as an explosion-proof equipment, handle the product with
special care for safety.
Never touch the cooling fins with bare hands during maintenance.
Sharp edges of the fins may hurt user’s hands.
Do not touch the cooling fins with bare hands
Be careful of vaporization of specimen such as organic solution and
others which contain flammable material.
Use extreme caution about vaporization of flammable material such as
organic solvent and others. If any solvent not trapped enters into the
vacuum pump, it can be ignited and burnt.
Cooling Fins

Pre-freeze the container for specimen.
Never start the vacuum pump before inner walls of Cold Trap
has been cooled enough.
Install the container only when the trap has been vacuumed completely.
Replace the oil in the vacuum pump regularly.

■Model FDU-1110
6 pieces of flask for specimen, which contain water of 500 cc (pre-frozen) are mounted on the trap.
And amount of sublimation is calculated backward based on remaining amount of water in flasks
along with time passage.
Input voltage: AC220 V , 50 Hz
Room temperature: 20 °C
■Model FDU-2110
8 pieces of flask for specimen, which contain water of 375 cc (pre-frozen) ) are mounted on the trap.
And amount of sublimation is calculated backward based on remaining amount of water in flasks
along with time passage.
Input voltage: AC220 V , 50 Hz
Room temperature: 20 °C
Progress of sublimation depends on conditions in use such as room temperature, capacity
and shape of specimen container (round-bottom flask or bottle), characteristic and amount of
specimen, and condition of pre-freezing..

When any trouble is occurred, refer to Sec. 6, “Troubleshooting” and take appropriate measures.
Safety Functions
Safety Devices Functions Causes of Activations
Earth leakage
Breaker When activated, the breaker is
turned off to cut the power supply. Electric leakage or over-current occurred
Safety Valve for
Vacuum Pump
(Leak Valve)
This valve prevents the oil contained
in the pump flows into the vacuum
system where the valve is opened,
and the system is subjected to
the air.
Activated where the operation of the pump is
interrupted by any power failure or accident
during experiment.
Activated where freeze-drying is completed, thus
Auto operation is terminated. Or defrosting is
completed.
Activated where freeze-drying is completed, and then,
the pump is stopped by manual operation.

* Once the overload relay in refrigerator is activated, cool down the refrigerator until the relay recovers.
Turn on and off the power switch to restart the refrigerator.
Recovery time for the overload relay depends on conditions in use, so that it differs 3 to 40 minutes
Ambient temperature is too high.
Refrigerator filter is clogged.
Too many specimens are mounted at once.
Refrigerator starts (operates) under overload
