3-3: Tool Maintenance
3. Clean the orifice plate’s opening with a wooden skewer or a similar tool such as a
plastic pick.
Do not use a metal object to clean the opening of the orifice plate; doing so can
damage the plate.
4. Remove both parts from the vinegar and thoroughly rinse them with clean water.
5. Re-assemble the solution quick connect, re-installing the filter cartridge and orifice
plate in the proper order (see Figure 3-3).
Do not operate the DriMaster III without the orifice plate installed. If you do not
properly re-install the orifice plate in the solution quick connect as indicated in
Figure 3-3, equipment damage could result. Such equipment damage is not
covered by warranty.
