4.UNIT INSPECTION
This product has been inspected at the factory and released to the transportation agency without known damage. Inspect exterior of carton for evidence of rough handling in shipment. Unpack carefully. If damage is found, report immediately to the transportation agency.
5.EQUIPMENT PROTECTION FROM ENVIRONMENT
The metal parts of the unit may be subject to rust or corrosion in adverse environmental conditions. This oxidation could shorten the unit life. Salt spray or mist in seacoast areas, sulphur or chlorine from lawn watering systems and various chemical contaminants from industries such as paper mills and petroleum refineries are especially corrosive.
If the unit is to be installed in an area where contaminants are likely to be a problem, special attention should be given to the equipment location and exposure.
Avoid having lawn sprinkler heads spray directly on the unit cabinet.
In coastal areas, locate the unit on the side of the building away from the waterfront. 
Shielding provided by fence or shrubs may give some protection.
Regular maintenance will reduce the buildup of contaminants and help to protect the unit's finish.
!WARNING - Disconnect all electrical power to the unit before servicing. Disconnect power to both the indoor and outdoor units. NOTE: There may be more than one electrical disconnect switch. Failure to shut off power can cause electrical shock resulting in personal injury or death.
Frequent washing of the cabinet, fan blade and coil with fresh water.
Regular cleaning and waxing of the cabinet with good automobile polish.
A good liquid cleaner may be used several times a year to remove matter that will not wash off with water.
The best protection is frequent cleaning, maintenance and minimal exposure to contaminants.
