compromised if the unit remains off charge for several months.
YSI recommends that prior to storing, the battery should
be fully charged (8 hours minimum) and the power turned
off.
Fluid System
Fluid System Fluid System Fluid System
If the SPORT is to be inactive for longer than a week, we recommend that the
whole system be flushed completely out with either deionized or distilled water.
This will prevent any of the salts that are present in the buffer and reference
solutions from crystallizing and blocking the fluid path.
This can be done quite simply by first emptying all of the fluid bottles and then
rinsing and filling the supply bottles with distilled or deionized water. The
system can then be either cycled using the priming function available in RUN
mode, or it may be done through DIAGNOSTICS using the individual
functions.
Storage of the unit for less than a week can be done with the buffer and
reference fluids in place.
NOTE: NOTE: NOTE: NOTE: It is possible that after a period of storage, depending on the tubing
condition, the tubing inside the pump may stick closed preventing fluid flow.
Depending on whether it happens to the waste or supply tubing, the chamber
may overflow or it simply may not fill correctly when attempting to run the unit
for the first time. Should either of these things happen, refer to Section 9
Troubleshooting, for instructions on how to correct the problem.
