Page 17: Maintenance
8 Maintenance 8.1 Bakeout The valve is baked in order for its inner parts to be degassed. Undesirable gases can thus be pumped. The pumping time is reduced and the final pressure is reached faster. It is good practice to bake out valves after cleaning (→ 23) and when their inner parts have been exposed to atmosphere for some time, e.g. - Page 18 Place the valve on the rotary knob and carefully unscrew the valve plate by turning it clockwise with the supplied tool. Supplied tool Valve plate Take out the valve plate with the supplied tool. Caution Caution: sealing edge The sealing edge can easily get damaged by a tool or the valve plate.
