Air Filter and Brackets

Installation (Optional)

The air filter (part number 3000-F1-020) prevents dust from entering the carrier. It is an optional component and must be ordered separately. However, the air filter brackets and screws are supplied with the CO Power Unit.

Only the 3000-F1-020 air filter may be used. Under normal environmental conditions, you should inspect and/or replace the 3000-F1-020 air filter every three months.

This section describes the procedure for installing the air filter and brackets. This procedure must be performed before installing the carrier into the cabinet.

NOTE

If the carriers in the cabinet are stacked directly on top of each other, then only the bottom carrier in the cabinet needs an air filter.

Keep in mind that the air filter brackets take up an additional 0.6 inches (1.5 cm) in height and if mounted on one of the carriers in the COMSPHERE 72-inch cabinet (4000-B2-201), then only five carriers can be installed in the cabinet instead of the usual six.

To install the air filter and brackets:

"Procedure

1.Raise the carrier 0.6 inches from the bottom of the cabinet (or above the carrier below it).

2.Fasten the two identical brackets to the bottom of the CO power tray using the four # 6 Phillips-head screws provided. See Figure 2-11.

3.Place the air filter with the grill-side face up on the guides of the brackets and slide the air filter in place.

If you were directed to this section during the CO Power Unit Installation procedure, then return to that procedure now.
