CORROSIVE ENVIRONMENT
The metal parts of this unit may be subject to rust or deterioration if exposed to a
corrosive 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 industries such as paper mills and petroleum refineries.
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 water-
front.
• Shielding provided by a fence or shrubs may give some protection, but cannot
violate minimum airflow and service access clearances.
• 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 build-up of contaminants and help to protect
the unit’s finish.
• 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.
• Regular cleaning and waxing of the cabinet with an automobile polish will pro-
vide some protection.
• 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.
FOR CONDENSERS WITH SPACE LIMITATIONS
In the event that a space limitation exists, we will permit the following clearances:
Single Unit Applications: One condenser inlet air grille side may be reduced to no
less than a 6-inch clearance. Clearances below 6 inches will reduce unit capacity
and efficiency. Do not reduce the 60-inch discharge, or the 24-inch service clearances.
Multiple Unit Applications: When multiple condenser grille sides are aligned, a 6inch per unit clearance is recommended, for a total of 12 inches between two units.
Two combined clearances below 12 inches will reduce capacity and efficiency. Do
not reduce the 60-inch discharge, or 24-inch service, clearances.
CUSTOMER SATISFACTION ISSUES
• The condenser should be located away from the living, sleeping and recreation-
al spaces of the owner and those spaces on adjoining property.
• To prevent noise transmission, the mounting pad for the outdoor unit should
not be connected to the structure, and should be located sufficient distance
above grade to prevent ground water from entering the unit.
