2.LOCATION CONSIDERATIONS
The metal parts of this unit may be subject to rust or deterioration in adverse envi- ronmental conditions. This oxidation could shorten the equipment’s useful life. Salt spray, fog or mist in seacoast areas, sulphur or chlorine from lawn watering systems, and various chemical contaminants from industries such as paper mills and petrole- um refineries are especially corrosive.
If the unit is to be installed in an area where contaminants are likely to be a problem, give special attention 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 water- front.
3.Shielding by a fence or shrubs may give some protection.
!WARNING
DISCONNECT ALL POWER TO UNIT BEFORE STARTING MAINTENANCE. FAILURE TO DO SO CAN CAUSE ELECTRICAL SHOCK RESULTING IN PER- SONAL INJURY OR DEATH. REGULAR MAINTENANCE WILL REDUCE THE BUILDUP OF CONTAMINANTS AND HELP TO PROTECT THE UNIT’S FINISH.
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 a good automobile polish will pro- vide some protection.
3.A good 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 ver- ified by the equipment manufacturer.
The best protection is frequent cleaning, maintenance and minimal exposure to contaminants.
