External Filter Maintenance

Routine Maintenance

Aluminum mesh, 2-inch deep filters are located in the supply weatherhood (if the weatherhood option was purchased). Filters should be checked and cleaned on a regular basis for best efficiency. The frequency of cleaning depends upon the cleanliness of the incoming air. These filters should be cleaned prior to start-up.

To access these filters, remove bottom bolt in the access door on the side of the weatherhood (one access door on each side of weatherhood). Slide the access door up and then pull bottom out to remove door. Then, slide the filters out (see FIGURE 23).

Clean filters by rinsing with a mild detergent in warm water. After the filters are dry, an adhesive spray, available at most filter distributors, may be applied to increase filter efficiency.

Internal Filter Maintenance

The APEX will typically be provided with 2-inch, pleated filters in the outdoor air and exhaust airstreams. These filters should be checked per a routine maintenance schedule and replaced as necessary to ensure proper airflow through the unit. See TABLE 4 for pleated filter size and quantity for each unit.

Outdoor Air Filters: Access to the outdoor air filters is through the doors labeled as “Filter Access” (both sides of unit). The filters are stacked two high and four deep. They can be removed by pulling on the strap mechanism (see FIGURE 24). Be sure to replace strap mechanism to assist with filter replacement for next maintenance interval.

Exhaust Air Filters: Access to the exhaust filters is through the door labeled “Coil Access”. You must enter the unit to get at the exhaust filter access door. This door is located in the divider between the airstreams (see FIGURE 25). Open the door and pull the exhaust filters up and out of the “V” bank rack.

Door Seal Maintenance

Slip-on type vinyl seal is installed on the perimeter of the door openings of the APEX. Seal should be inspected at least annually to ensure that seal is still pliable and intact.
