Step 8
Repeat steps 4 through 7 for all columns that need a fan box replaced. All fan boxes
must be disposed of correctly. When completed, it will look like Figure 8-19.
Step 9
When all fan boxes have been replaced, connect the filtered hood to power. Power up
and check all lights and fans are working properly. If the filtered hood is in alarm, check
eGuard for the explanation. If eGuard says the XXX sensor or fan(s) has been replaced,
press the
[mute]
button on the command module. If the alarm is anything other than a
replaced message, disconnect the power, re-check all electrical connections and try
again.
When properly working, reinstall the front panel and resume using the filtered hood.
Optional HEPA Filter Installation or Replacement
While the Neutrodine filters are great for liquid chemicals and vapors, the optional
HEPA filter is required for powder or particulate capture. If using HEPA filters,
the fan’s
recommended maximum Working Setpoint will increase from 2,400 rpm to 2,600 rpm. In
addition, the HEPA filters need replacing either annually or if the face velocity drops
below the recommended speed (airflow alarm active with sash at operating height),
which ever happens first.
The standard filtration technology column figuration discussed previously in this manual
is called “2C”. The “2C” configuration is built as follows (from bottom to top): base
frame, primary filter, fan box and secondary filter. There are two kinds of filtration
column configurations that utilize the optional HEPA filters, 1P2C and 2C1P, which will
be talked about in this section.
