CHAPTER 9: CLEANING AND MAINTENANCE
This chapter provides information on how to clean and maintain your
Harmony system.
9.1 CLEANING THE HARMONY
Before cleaning or performing any routine maintenance, always make
sure the Harmony is not operating and disconnect the Harmony from
the power source.
NOTE: The following cleaning instructions are for the Harmony only.
To clean the accessories, refer to each accessory’s instruction
sheet.
CAUTION: Do not immerse the Harmony or allow any liquid to enter
the enclosure, inlet filter, or any openings.
Clean the front panel and exterior of the enclosure as needed using a
cloth dampened with water and a mild detergent. Allow the Harmony
to dry completely before plugging in the power cord.
Gently wash the reusable circuit tubing in a solution of warm water and
a mild detergent. Rinse thoroughly and allow to air dry.
9.2 CLEANING OR REPLACING THE INLET FILTERS
The Harmony has two removable filters at the air inlet. The gray foam
filter is washable and reusable. The optional white, ultra-fine filter is
disposable.
NOTE: Dirty inlet filters may cause high operating temperatures and
may affect Harmony performance. Regularly examine the inlet
filters as needed for integrity and cleanliness.
1. Make sure the Harmony is not operating, and disconnect the power
cord from the wall outlet.
2. As shown in Figure 9–1, remove the filter cap by gently pressing
down on the top panel and pulling the cap out from Harmony’s
body.
