Installing the Permeation Device(s)

1. Turn off the power switch.

2. With the tool provided, rotate the panel lock screw 90° counterclockwise.

3. Gently pull the front panel assembly out.

CAUTION: The permeation chamber cap may be warm to

touch. If the calibrator has been in use, avoid exposure

to gas vapors while opening the chamber cap by using

appropriate mitigation and personal protection equipment.

4. Unscrew the chamber cap with the tool provided.

5. Add or remove the permeation device(s) with the supplied forceps or

other tool appropriate to the job.

6. Secure the chamber cap with the tool provided.

7. Run a pressure/decay test to make sure that the chamber cap is leak

tight.

8. Reinstall the front panel assembly and rotate the panel lock screw 90°

clockwise.

9. Turn on the power switch and allow one hour for equilibration.

Refer to the separate instructions accompanying the permeation tube to

make sure that the selected temperature is compatible with the permeation

tube being used.
