Section Nine – Maintenance
Media-Mate Plus has been designed to be a low maintenance instrument. In general, the
instrument is maintained by proper cleaning after use, periodic replacement of the filter element
and periodic lubrication of fill tubes.
The Media-Mate Plus has type 316 stainless steel in the liquid flow path. HCl can effect the
316 stainless steel, especially when the solution is left to dry.
When using HCl, rinse the Media-Mate Plus with D.I. water when finished. Do not allow the HCl
to set in the unit for long periods of time (4 hours or more). Rinse off any external spillage
immediately.
General Cleaning
See
Section 5
for identification of parts.
The exterior of the Instrument should be periodically wiped down with a damp cloth. Particular
attention should be given to the Volume Adjust Components located on the Dispense
Assembly. Frequency of cleaning depends on Instrument usage and operating environment.
Cleaning the Media Tank and Fluid Lines
NOTE:
Always unplug the Heater Assembly.
The Media Tank should always be cleaned prior to filling the Tank with new media, or if it will
not be used within 36 hours.
Cleaning Method:
1.
Disconnect the Fill Tube Assembly at the Fill Manifold and drain the Tank out the Fill Tube.
The side of the Tank housing the Filter Assembly may be shifted off of the Support Rail in
order to facilitate more complete draining.
2.
Remove the Tank and pour out any remaining media and wipe dry.
3.
Replace the Tank and reconnect the Fill Tube Assembly at the Fill Manifold.
4.
Fill the Tank with clean DI water and run a couple of Test Cycles (see
Section 7 – “Test
Cycle”
).
5.
Repeat Steps 1 - 3.
6.
With the Tank empty, run two dry Test Cycles (see
Section 7 – “Test Cycle”).
This will
help dry the fluid passages and leave the Instrument ready for the next usage.
7.
If the Instrument is not going to be used within 15 days, it should be covered and moved
to an appropriate storage location.
