1. Risks and Safety Measure upon Maintenance and Repair
Warning
Wear protective
gear
Wear a dust-proof mask and gloves to clean the thin
film adhered to the inside of the glass bell jar and
feed-through collar.
The thin film could by broken into minute particles,
and float in the air, which could be inhaled into the
human body.
Wear protective
gear
Wear a dust-proof mask and gloves to replace the oil
of the oil diffusion pump and the oil sealed rotary
vacuum pump.
This could cause risk to human health.
Check
Since the glass bell jar weighs 7 kg, installation and
removal should be made with correct posture. Work
without correct posture may cause an accidental
drop of jar or lower back injuries. Otherwise, you
could injure your back.
Check
Check everyday for looseness of the fixture clips and
eyebolts of both ends of the wire rope for lift (sold
separately).
If they are loose, the bell jar could accidentally drop.
Caution
Work by two or
more people
Installation and removal of the oil diffusion pump and
oil sealed rotary vacuum pump should be performed
by two or more people.
Otherwise, you could injure your back.
Replace
periodically
Oil mist trap (sold separately) should be replaced
every six months to one year.
Clogging in the element increases evacuation
resistance, which may cause oil leakage from the
axis sealing area or oil level gauge damage.
Comply with
regulations
To dispose the oil (waste oil) for the pump, comply
with industrial waste disposal rules.
Comply with regulations upon disposal.
