2.4.3 Changing Mixer Capacity
Be sure to follow these directions carefully. The mixer may leak if it is assembled incorrectly, or if an O-ring
is not correctly placed in the O-ring groove.
Note: Flush any hazardous material from the system. Drain fluid from the mixer and disconnect the
mixer plumbing and cables.
1. If you will be changing the mixer capacity, use the information in Table 2-10 and Table 2-11 to select
the appropriate screws and barrel extension.
2. Use the hex key provided to remove the four screws from the top of the mixer (see Figure 2-4).
3. Remove the mixer top and turn it upside down to remove the O-ring. If the O-ring does not easily
dislodge, use your fingers to remove it.
4. Refer to Figure 2-4 for re-assembling the mixer. Make sure that the magnetic stir bar lies flat. If the
standard mixer barrel is to be used, assure the O-ring groove faces up.
5. Place an O-ring in each O-ring groove. If you are using only the mixer body, only one O-ring is
required. If the mixer barrel is used, two O-rings are required.
