Manual Zone Disable Mode
Manual Zone Disable Mode allows a customer or Service Technician to switch one zone off for interior cleaning,

zone chosen, indicating all cooling functions for that zone are disabled. To return the unit to normal operation,
repeat the steps above, or press UNIT ON/OFF key.
