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.
6.INSTALLATION
6.1.GENERAL
These units are designed for outdoor installations. They can be mounted on a slab or rooftop. It
is important to consult your local code authorities at the time the first installation is made.
Check following points before attempting any installation:
Structural strength of supporting members.
Clearances and provision for servicing.
Power supply and wiring.
Location for minimum noise, where operating sounds will not disturb owner or neighbors.
Location where there is no risk of combustible gas leakage.
Location where external water drainage cannot collect around the unit.
Location where roof runoff water does not pour directly on the unit. Provide gutter or other
shielding at roof level. Don't locate unit in an area where excessive snow drifting may occur
or accumulate.
