Media-Mate Plus Operation Manual 25-710-800-OLubricationThe Fill Tubes (see Figure 6-1) should be lubricated every six-months to maintain easymovement and to facilitate easy adjustment of the Volume Setting.To Lubricate:1. Adjust the Volume Delivery Setting to 1000 mL (see Section 7 – “Volume Selection”).2. Apply a small amount of silicone grease (p/n 91-951-004) to the exterior of the Fill Tubesbetween the Pointer and the vessel cover.3. Loosen the upper lock screw and rotate the Pointer in order to disengage the incrementalstandard.4. Move the Fill Tube up and down several times between the upper and lower extremepositions.5. Raise the Fill Tube to the upper position and remove excess grease.6. Reset Volume Selection (see Section 7 – “Volume Section”).Replacing the Filter ElementA clogged Filter Element will restrict media flow and impair Instrument performance. The FilterElement should be replaced every 90-days or whenever the Fill Level is reduced by 25 mL (thismay be observed during the Fill Cycle). Also, since the Filter Element will retain a small volumeof media, it must be replaced whenever the Tank is to be filled with a media that is differentthan the media that was previously used.Replacing the element for units without a filter housing:1. Unscrew the Filter Core Assembly and remove it from the Tank along with the Elementand Washers (see Figure 9-1).2. Discard the Element and replace with a new Element (p/n 91-500-099).Figure: 9-1Section 9 Maintenance 34
