Hiqh Altitude Operation
Because the air is less dense at higher altitudes, there is a possibility of
nuisance arcing. The homeowner can quickly and easily correct this
condition.
1. TurntheunitOFE Disconnectcordorturnoffcircuitbreaker.
2. Remove the two screws that secure the cover to the power tray and
remove it from the unit. (The entire power supply tray may be removed
from the cabinet by removing two screws from inside the cabinet.) Do
not lose these screws.
3. Locatethejumperterminal (seefigure2).
4. With a pair of needle nose pliers, carefully adjust the jumper settings
from HIGH to MED. Ensure that the jumper is firmly seated in the
terminal.
5. Replace the power tray cover and secure it with the two screws.
6. Replacethe access door and turn the unit ON.
This procedure will slightly reduce the output voltage, minimize arcing and
reduce ozone production. If the condition does not improve, repeat the
above procedure and move the jumper setting from MED to LOW. If this
does not correct the situation, contact your local HVAC dealer.
All Electronic Air Cleaners are produced at the factory with the jumpers set in
the HIGH position. However, the output voltage may be lowered in any
situation where the unit is arcing excessively or there is excessive ozone
production.
