5. Daily Test:

a) Every day before starting operation, dry the cold trap

and the sample chamber using a lint free cloth. Do not

use paper towel as pieces of paper can get left in the

system and subsequently be pulled into the vacuum

pump.

b) Place the appropriate lids on the sample chamber and

the cold trap. Press start to begin a test without any

samples. The vacuum reading on the display should be

6 mmHg or less when complete. If the vacuum without

a sample is higher than 6 mmHg, refer to the trouble

shooting section or call InstroTek for service information.

Note: When you receive the CoreDry or after transport to

other locations, you might have to run the CoreDry several

cycles to achieve 6 mmHg. Moisture from humidity might

build up within the vacuum lines. By running the unit several

times, the CoreDry eliminates the moisture in the pipes and

reduces the pressure within the chamber to 6 mmHg.
