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 refineries are
especially corrosive.

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.

Disconnect all power to unit before starting maintenance.
Failure to do so can cause electrical shock resulting in
personal 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 provide 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 verified by
the equipment manufacturer.
The best protection is frequent cleaning, maintenance and
minimal exposure to contaminants.

Outside Installation

!
These units are designed certified 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 flue
products into the conditioned space resulting in personal
injury or death.
(Typical outdoor slab installation is shown in Figure 5.)
1 Select a location where external water drainage cannot
collect around unit.
2 Provide a level slab sufficiently high enough above grade
to prevent surface water from entering the unit
3 The location of the unit should be such as to provide
proper access for inspection and servicing as shown in
Figure 7.
