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. Use a good liquid cleaner 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.
B. OUTSIDE INSTALLATION
(Typical outdoor slab installation is shown in Figure 2.)
1. Select a location where external water drainage cannot collect around unit.
2. Provide a slab sufficiently high enough above grade to prevent surface water from
entering the unit. Where snowfall is anticipated, mount the unit above the anticipat-
ed maximum snow depth for your area. The slab should be isolated from the foun-
dation wall.
3. Pitch the slab approximately
1
⁄2” so that the unit will be pitched toward the drain. See
Figure 3.
4. The location of the unit should be such as to provide proper access for inspection
and servicing as shown in Figure 9.
