Replacing Filters Ð Filters can be removed and in- stalled from either side of the unit. Install new ®lters in units that have one fan as follows:

1.Remove the side access panel (retain screws).

2.Remove the ®lter retainer clip.

3.Remove old ®lters by tilting them and lifting them out of the ®lter track. See Fig. 12 and 22.

4.Reverse the procedure to install new ®lters.

To install new ®lters in larger units that have 2 fans, fol- low the preceding steps, but use the factory-supplied ®lter hook to slide ®lters within reach for removal. The ®lter hook is shipped inside the unit in the baserail.

Do not operate unit without air ®lters.
