2.10.1 General. Dusty and sandy conditions can seriously reduce the efficiency of the air conditioner by clogging
the air filter, mist eliminator and coils. This will cause a restriction in the volume of airflow. Accumulation of dust or
sand in the condenser coil and/or in the compressor compartment may cause overheating of the refrigeration system.
Dust or sand may also clog the condensate trap and water drain lines.
Never operate the air conditioner without having the air filters in place.

a. Shield the air conditioner from dust as much as possible.
b. Take advantage of any natural barriers which offer protection.
