6.2 Routine Maintenance
Each day the following checks should be made:
♦
C h e c k the temperature readout on the instrument's LCD display.Verify
that the temperature is currently at 35° C ±1.50 C. Also check the
reading on the temperature QC vial. If the readings are not 35° C
± 1.5° C, refer to the instructions in Section 7 -Troubleshooting.
♦
I f you have an optional printer, check its paper supply. If the paper
supply is low or exhausted, replace the paper.
6.2.1 A i r Filter Replacement
Change or clean the air filters on both sides of the instrument monthly. If the
instrument's environment is especially dusty, check the filter more frequently.
These filters must remain clean and unobstructed; restricted air flow may cause
the vials to reach excessive temperatures, which can affect organism recovery
and possibly cause hardware malfunctions or failures.The filters can be cleaned
and reused. See Figure 18.
Required Materials
New or clean air filters

Replace
the Air Filters
1 T h e air filters are located on the sides of the instrument near the bottom.

place it on a paper towel (if you are going to reuse it immediately).
