When you are going to continue operation
5-9-2.
When finishing use of the unit
(1) Prepare the decompression container (concentrating unit), the
cooling circulator, the vacuum pump and the solvent control unit
for continued operation.
※
When a waste trap is used, check the amount of waste in it.
Remove the waste before its amount exceeds 2/3 of the
trap container capacity.
The waste trap may not be functional if the waste amount
exceeds the 2/3 of the container capacity.
※
When the receiving flask contains considerable amount of
collected liquid, remove it and process.
(2) Repeat operations as specified in the manual.
(1) Release compression of the decompression container
(concentration unit) or in the connection pipes.
Pressing the [Leak] key opens the leak valve to draw in
atmospheric air.
Pressing the key again closes the leak valve.
(2) Make the decompression container (concentrating unit) open to
the atmosphere to avoid decompression even if it is operated.
(3) Clean the inside of the diaphragm vacuum pump and the
connecting pipes.
Keep the [Leak] key for 30 seconds or more while “Standby” is
displayed starts cleaning which will ends automatically.
※
If any liquid is trapped in the waste trap, remove it to empty
the trap.
※
When the receiving flask contains considerable amount of
collected liquid, remove it and process.
※
If cleaning is not carried out before completion of use,
deterioration of the sensor, the solenoid valve and the
diaphragm vacuum pump will accelerate.
(4) Stop the decompression container (concentration unit) and the
cooling circulator.
Properly handle each device referring to its instruction manual.
(5) Turn the power switches of the main unit and the diaphragm
vacuum pump OFF.
※
Remove the power plug off the outlet if you are not going to
use the unit for an extended period of time.
