sticker. Remove the secondary sticker if needed to make the new label clear. To review
how to install filters see
Section 4: Filtration Installation
. Once stacked, make sure the
locators are inserted firmly and the electrical connections are good. Remove the cap
covering the electrical connection and save.
Step 7
From here, the fan box and the new filter are stacked back on the column. Start with the
fan, making sure the seal is tight and electrical connection is good. The fan (should
already be labeled with column number) should match the number of the new primary
filter and the column it is placed in.
Next, the new filter will be placed on top of the fan box. Once in place, label it as the
secondary filter with the column number (will match the fan and primary number) and
with the letter “S”. Make sure the secondary filter has a cap covering the electrical plug
on the top of the filter. If not there, use the cap taken from the old secondary filter when
you made it the primary.
For more detailed instructions on how to place and label filters and fan boxes see
Section 4: Filtration Installation
Step 8
Repeat steps 4 through 7 for all columns. All primary filters must be replaced at once
and disposed of correctly. When completed, it will look like Figure 8-16.
Step 9
When all primary filters have been replaced, plug the filtered hood back in. Power up
and check all lights, fans and filters are working properly. If the hood is in alarm, check
eGuard for the explanation. If eGuard says the Primary/Secondary filter(s) have been
replaced, press the
[mute]
button on the command module. If the alarm is anything
other than the replaced message, disconnect the power, re-check all electrical
connections and try again. Do not leave the filtered hood running while troubleshooting.
When properly working, reinstall the front panel and resume using the filtered hood.
