II. INTRODUCTION
This booklet contains the installation and operating instructions for your self-contained
air conditioner. There are a few precautions that should be taken to derive maximum
satisfaction from it. Improper installation can result in unsatisfactory operation or dan-
gerous conditions.

make up the system prior to installation. Give this booklet to the owner and explain its
provisions. The owner should retain this booklet for future reference.
III. CHECKING PRODUCT RECEIVED
Upon receiving the unit, inspect it for any damage from shipment. Claims for damage,
either shipping or concealed, should be filed immediately with the shipping company.
Check the unit model number, electrical characteristics, and accessories to determine
if they are correct.
IV. EQUIPMENT PROTECTION FROM THE
IV. ENVIRONMENT
The metal parts of this unit may be subject to rust or deterioration in adverse environ-
mental 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 var-
ious chemical contaminants from industries such as paper mills and petroleum refiner-
ies are especially corrosive.
If the unit is to be installed in an area where contaminants are likely to be a prob-
lem, special attention should be given to the equipment location and exposure.
1. Avoid having lawn sprinkler heads spray direction on the unit cabinet.
2. In coastal areas, locate the unit on the side of the building away from the water-
front.
3. Shielding provided by a fence or shrubs may give some protection.
Regular maintenance will reduce the buildup of contaminents and help to pro-
tect 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 pro-
vide 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 coat-
ings 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.
