6. Re-assemble the frame as described in the previous steps.
To install a fan in the Cloth Door Panel
1. Determine which direction the air is required to flow, and align the fan
according to the airflow indicator on the Fan Top panel. Airflow into an
enclosure pressurizes the enclosure, and airflow out of an enclosure
depressurizes.
2. Hook the bottom of the fan into the cloth fan hole.
3. Guide the elastic ring of the fan hole around the fan casing. The elastic
around the fan hole can be tightened, if required, on some
versions of the Cloth Door Panel. A tight fit is required to
prevent air leakage.
4. Use the Velcro fan strap on the horizontal crossbar to hold the fan in place. The elastic should not be
supporting the weight of the fan.
5. 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.

3.2 Modular Hard Sided Door Panels
A Modular Door Panel is standard with two Door Fan systems: models
Q56 and Q5E (see Appendix E for conversion of the old model names
to the new ones). If purchased separately, the Modular Door Panel
can be used with most Retrotec 2000 and 3300 fans. A special adaptor
plate is also available to incorporate Retrotec’s low-flow (DucTester)
fans for use with the modular panel.
The modular panel consists of the following parts:
1 only Fan Panel with fan strap
1 only Large-X panel
1 only XY panel
2 only Fan Panel fill sheets (one large, one small)
