Installation Instructions
Use the adaptive centering ring to seal the reducer
with the vent valve.
The KF16 clamp is used to
secure the valve body (KF10 flange) to the reducer.
The adaptive centering ring is orientation
specific. Make sure that it seats flush with both
the reducer and the valve flange.
To close the valve when establishing a vacuum
under the bell jar, rotate the wing nut clockwise until
it is tight.
To open and release applied vacuum, start by slowly
opening the valve to gradually expose the bell jar to
atmospheric pressure. Do not release vacuum so
quickly that vapor formation is observed under the
bell jar.
It is not recommended to use vacuum grease on
the valve body o-ring. If it gets dirty or appears
to lose its seal: remove, clean with soap and
water and re-install.
