2. Attach a Fan Panel fill sheet to cover any gap that is created by expanding the
Fan Panel.
3. Install the Large-X panel, so that it is touching the top of the door frame.
Expand it so that it is held in place securely.
4. If required, install a Small-X panel just below the Large-X panel.
5. Install the XY panel. Expand it both vertically and horizontally to completely
seal the doorway.
6. Grill mask can be used to seal any small gaps that remain.
7. A second Fan Panel can be substituted for the Large-X panel if required.
However, it should be placed directly above the first Fan Panel, with the Small-X
or XY panel being used at the top of the doorway instead.
To install a fan in a Modular Door Panel
1. Determine which direction of airflow is required and align the fan
according to the airflow indicator on the top Fan Panel. Airflow into an
enclosure pressurizes the enclosure, and airflow out of an enclosure
depressurizes.
2. Insert the bottom of the fan into the Fan Panel.
3. Align the notches on the fan with the corresponding notches on the
Fan Panel.
4. Push the fan into the hole, and rotate the fan slightly to secure it in the
panel.
5. Hook the fan strap over the edge of the fan shell to hold it in place.
6. Double-check that the fan airflow is in the correct direction. It will be
much harder to switch the fan around once all of the equipment has
been connected.
3.3 Triple-Fan Molded Panel Set for multiple fan tests
The Triple-Fan Molded Panel Set is a specially designed folding panel which supports up to three 3000 Retrotec fans
in one doorway. The panel is included with the QMG system, or can be ordered separately. Blanking plates are
included with the Molded Panel Set, so that it can be used with fewer than three fans if required.
