Location Considerations
The metal parts of this unit may be subject to rust or
deterioration in adverse environmental 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 petroleum reneries 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 waterfront.
3. Shielding by a fence or shrubs may give some
protection.
4. 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.
5. Regular cleaning and waxing of the cabinet with a good
automobile polish will provide some protection.
6. A good liquid cleaner may be used several times a year
to remove matter that will not wash o with water.
Several dierent types of protective coatings are oered in
some areas. These coatings may provide some benet, but the
eectiveness of such coating materials cannot be veried by
the equipment manufacturer.
The best protection is frequent cleaning, maintenance, and
minimal exposure to contaminants.
Clearances
The minimum clearances shown in Figure 3 on page
6 must be observed for proper unit performance and
serviceability.
Horizontal Conversion Procedure
Outside Slab Installation
NOTICE
These units are designed certied for outdoor installation only. Installation
inside any part of a structure can result in inadequate unit performance as
well as property damage. Installation inside can also cause recirculation
of ue products into the conditioned space resulting in personal injury or
death.
Typical outdoor slab installation is shown in Figure 1.
1. Select a location where external water drainage cannot
collect around unit.
2. Provide a level slab suciently high enough above grade
to prevent surface water from entering the unit
3. Locate the unit to provide proper access for inspection
and servicing as shown in Figure 3.
4. Locate unit where operating sounds will not disturb
owner or neighbors.
5. Locate unit so roof runo water does not pour directly on
the unit. Provide gutter or other shielding at roof level.Do
not locate unit in an area where excessive snow drifting
may occur or accumulate.
6. Where snowfall is anticipated, the height of the unit
above the ground level must be considered. Mount
unit high enough to be above anticipated maximum
area snowfall and to allow combustion air to enter the
combustion air inlet.
7. Select an area which will keep the areas of the vent,
air intake, and A/C condenser ns free and clear of
obstructions such as weeds, shrubs, vines, snow, etc.
Inform the user accordingly.
