Maintenance - Dometic 3314080.000 BLACK Operating Instructions Manual

MAINTENANCE

A. Air Filter
 P eriodic cleaning or replacement of the air conditioner/heat pump air filters
is required. NEVER run the air conditioner without the air filter in place. This
may plug the unit evaporator coil with dirt and may substantially degrade the
performance of the unit over time.
When a system fan run time exceeds 1000 hours the filter icon is displayed in the
LCD. (See section, "D. Quick Reference To LCD Icons" on page (5).) When this
occurs wash the filter with soap and warm water. Let dry and reinstall.
To reset the fan run time and clear the filter 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
 D O 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.
