MAINTENANCE

4.1

GENERAL

The life expectancy of the liquid handling components in any equipment that contact saline 
solutions depends largely upon operator care.  Allowing the wash solution in the manifold, 
tubing or dispense pump to dry out will create problems. The salt deposits left by the dried 
wash solution can easily clog  the system.  This instrument is designed to help prevent 
clogging or dried salt deposits by keeping its components wet (as long as the power is left on, 
and its Rinse reservoir is connected and full). When not in use, the system should be rinsed 
twice with distilled water. The AutoRinse valve will switch to the Rinse reservoir automatically 
when the power is left on.

4.2

MAINTENANCE SCHEDULE AND SERVICE RECORD

See pages 23 and 24 for suggested maintenance schedule and sample service records.

4.3

INLET LINE FILTERS—WASH AND RINSE RESERVOIRS

It is recommended that the inlet line filters in both the Wash and Rinse reservoirs be back-
flushed at least once every week if wash solution is left standing in the bottle for long periods 
of time. This removes trapped particles and prevents excessive back pressure on the dispense 
pump and syringe assembly.  The filters can be removed from the inlet tubings and a syringe 
filled with an appropriate rinse solution such as distilled water can be used to backflush the 
filters. Do not rinse with strong acids or solvents. 

4.4

ASPIRATE EXHAUST FILTER

The exhaust filter material (two ordinary cotton balls) should be replaced periodically,  
depending on the amount of use.  Open the exhaust cap on the rear panel, and replace as 
needed.

4.5

DISPENSE PUMP AND SYRINGE ASSEMBLY ON BACK PANEL

Rinsing twice with distilled water is required, before turning instrument off.
