To assemble the sample gas pump, perform the steps in reverse order. When tightening the inlet and outlet valves be sure to ob-
serve the required tightening torque of max. 1 Nm.
CAUTION! Tightening the valves more will permanently deform the pump
body, requiring replacement.
When installing the screw connection, ensure the connection is tight.
7.9 Replacing the O-ring on the bypass valve (optional)
– Loosen the two screws on the valve plate and carefully remove the entire unit.
– Coat the new O-ring with suitable O-ring grease (e.g. Fluoronox S90/2) and install in the spindle.
– Carefully insert the entire unit into the pump body while turning and tighten screws.
7.10 Replacing the bellow (optional)
To replace the bellow carefully unscrew it from the connecting rod counter clockwise. Be sure not to lose any installed shims.
Before reinstalling the bellow be sure it is not damaged.
Reinstall hand tight in reverse order.
