Check
Make sure the vaporization power output is switched OFF
before using the electrode switch.
May cause sparks or damage to the switch.
Prohibited
Do not strike the glass bell jar or heat it to above 50°C.
Damaging the inner mechanism while there is a vacuum
can cause fragments to fly out.
May cause damage.
Warning
Check
ventilation
Make sure the room is well-ventilated when using liquid
nitrogen.
Vapor from the liquid nitrogen can lower the oxygen levels
in the room.
May cause accidents due to lack of oxygen.
Wear gloves
When handling liquid nitrogen, wear rubber gloves or
other protection over exposed areas of skin.
A droplet coming into contact with your skin can be extremely painful.
Venting
After stopping the oil-sealed rotary vacuum pump, open
the RP vent and vent the inside of the rough pipe to the
atmosphere.
Prevents oil backflow.
Caution
Check it is
completely
closed
After confirming that the main valve is completely closed,
vent the inside of the bell jar to the atmosphere.
If air enters the oil diffusion pump while it is in operation, the oil from
the oil diffusion pump will be degraded and its performance will
deteriorate sharply.
If air is allowed to enter while liquid nitrogen is being poured in, large
amounts of condensed gas will gather in the trap and the
performance will deteriorate sharply.
