Remove dust cap.2. Put the gauge with the centering onto the connection of theapparatus  small flange KF DN16.3. Fix the vacuum gauge with a clamping ring.Connection via hose nozzleRequired connection material: Hose nozzle DN 6/10 mm G1/4”with O ring and compatible hose clip (option).1. Remove dust cap.2. Screw the hose nozzle plus the o ring hand‑tight into theinside thread.3. Use the hose nozzle to assemble the gauge to a vacuumhose or directly at the apparatus.4. Fix the vacuum hose, e. g., with a hose nozzle.5. Fix the vacuum gauge.> Use a stable vacuum hose that is suitable for the requiredvacuum range. For fine vacuum range, flexible rubber hosesfor example are not useful because of possible gas emis‑sion.> Connect hose tubes as short as possible.
