5.1 INSTALLING THE AIR FILTERS

CAUTION: A properly installed, undamaged foam filter is required

for proper operation.

The Harmony uses a gray foam filter that is washable and reusable, and

an optional white, ultra-fine filter that is disposable. One filter of each

kind is supplied with the Harmony.

If your home care provider did not install the inlet air filters, you must

install at least the gray foam filter before using the Harmony.

1. Place the gray foam filter on top of the ultra-fine filter (if using the

ultra-fine filter).

2. Slide the filters into the air inlet at the rear of the Harmony, and push

them down into the recess as shown in Figure 5-1.
