Have you completed all previous steps of configuration? If
unsure, start over at the very beginning by deleting the
configuration and creating a new one. Start at step 4 of
the reconfiguration process in the User’s Manual, page
31.
c. Refer to the User’s Manual and follow each step, step-by-
step with patience and attention.
d. If they continue to have difficulties, refer to tech support
at Erlab to complete the configuration.
During operation of the fume hood:
4) “The hood is in alarm, what do I do?”
a. Ask the caller to please read the screen to see what the
alpha-numeric alarm code is (i.e. 8S, 8Q, 8K, etc.). They
may need to press the OK button to see the code.
b. Refer to the GFH alarm code list (next page) to see what
the alarm is, possible causes and recommended actions
(e.g. lower sash, replace acid sensor, replace filters,
etc.).
c. Re-booting the GFH computer can remove a momentary
alarm situation. Ask the customer to cycle power to the
hood to see if that resets the issue. Either unplug the
hood completely, or simply pull out the black fuse holder
in the left-hand end of the GFH Command Module (the
Erlab box with the display screen). Wait 15 seconds and
then restore power. The hood will go through a re-boot
and takes a couple of minutes to be ready. Please be
patient.
d. If none of the above resolve the issue, refer the customer
to tech support at Erlab or Labconco as appropriate.
5) “The hood is in filter saturation alarm and its brand new!
What do I do?”
a. The saturation detection sensors are likely not yet fully
burned in. The hood should be left running for 24 to 48
hours to allow the sensors and their chamber to fully
purge and burn in.
