MAINTENANCE
A. Air Filter
NOTICE.
Periodic cleaning or replacement of the air conditioner/heat pump air
fi
l-
ters is required.
NEVER
run the air conditioner without the air
fi
lter in place. This
may plug the unit evaporator coil with dirt and may substantially degrade the perfor-
mance of the unit over time.
When a system fan run time exceeds 1000 hours the
fi
lter icon is displayed in the
LCD. (See section, “D. Quick Reference To LCD Icons” on page (5).) When this
occurs wash the
fi
lter with soap and warm water. Let dry and reinstall.
To reset the fan run time and clear the
fi
lter icon, hold the
INSIDE TEMP
and
°F / °C
buttons for 3 seconds. This will clear the fan run time for the current zone
selected.
B. Dometic CCC 2 Thermostat
NOTICE. DO NOT
spray water directly on the CCC 2 thermostat.
DO NOT
use
solvents for cleaning.
Clean the CCC 2 thermostat with a moist soft cloth.
