V. EQUIPMENT PROTECTION
IV (Corrosive Environment)
The metal parts of this unit may be subject to rust or deterioration if exposed to a cor-
rosive environment. This oxidation could shorten the equipment's useful life. Corrosive
elements include, but are not limited to, salt spray, fog or mist in seacoast areas, sulphur
or chlorine from lawn watering systems, and various chemical contaminants from indus-
tries such as paper mills and petroleum refineries.
If the unit is to be installed in an area where contaminants are likely to be a prob-
lem, special attention should be given to the equipment location and exposure.
1. Avoid having lawn sprinkler heads spray directly on the unit cabinet.
2. In coastal areas, locate the unit on the side of the building away from the waterfront.
3. Shielding provided by a fence or shrubs may give some protection.
4. Elevating the unit off its slab or base enough to allow air circulation will help avoid
holding water against the basepan.
Regular maintenance will reduce the buildup of contaminants and help to protect
the unit's finish.
WARNING
!
DISCONNECT ALL POWER TO THE UNIT BEFORE STARTING MAINTENANCE.
FAILURE TO DO SO CAN RESULT IN SEVERE ELECTRICAL SHOCK OR
DEATH.
1. Frequent washing of the cabinet, fan blade and coil with fresh water will remove
most of the salt or other contaminants that build up on the unit.
2. Regular cleaning and waxing of the cabinet with an automobile polish will provide
some protection.
3. A liquid cleaner may be used several times a year to remove matter that will not
wash off with water.
Several different types of protective coatings are offered in some areas. These coatings
may provide some benefit, but the effectiveness of such coating materials cannot be
verified by the equipment manufacturer.
The best protection is frequent cleaning, maintenance and minimal exposure to
contaminants.
