Optimizing Performance - EdgeStar AP420HS Owner's Manual

Optimizing Performance

For Maximum Performance and Efficiency:
1. Do not cover the exhaust air outlet (exhaust) while in use.
2. Do not place the unit in front of curtains or drapes- to ensure they do not obstruct the air
inlet.
3. Minimize the length of the exhaust hose.
4. Make sure the exhaust hose is as straight as possible.
5. Keep curtains, blinds or drapes closed during the sunniest part of the day.
6. Use the timer to operate the unit before it is needed. For example, set the timer to turn on
the unit in cool mode for 3 or more hours to cool the room before you arrive. You may
want to operate the unit all day if you live in a warmer climate.
7. Minimize the heat sources (direct sunlight, computers, servers, people, etc.) in the room.
8. Close all windows and doors.
9. Use the unit in a contained room. For example, a room with four walls and a roof, instead
of a partitioned studio, or warehouse.
10. Make sure the unit is on a level surface.
11. Minimize the amount of humidity in the room. For example, adding a dehumidifier.
12. To prolong the compressor's life, please wait at least 3 minutes before turning the unit
back on after shutting it off.
13. Inspect and keep the pre-filters clean by cleaning regularly.
14. Inspect and replace the activated carbon filters regularly.
15. Perform routine maintenance.
