8.7.9 Replace Acid Trap Filling
Preconditions: - Up to 2/3 of the brass wool has a red-brown discolouration.

1. Use a screwdriver to open the pipe clamps.
2. Take the tubes to the acid trap.
3. Take the acid trap from the holder.
4. Remove the contents of the acid trap.
5. Fill the quartz wool into the acid trip carefully because otherwise the quartz wool becomes
pulverised and a blockage of the gas paths is created when it is stuffed by too much (bottom).
6. Fill the zinc into the acid trap (middle).
7. Fill the brass wool into the acid trap (top). No brass wool may be protruding.
8. Check the order (from the bottom up): Quartz wool, zinc, brass wool.
