INTRODUCTION
THE MANUFACTURER’S WARRANTY DOES NOT COVER
ANY DAMAGE OR DEFECT TO THE HEAT PUMP CAUSED
BY THE ATTACHMENT OR USE OF ANY COMPONENTS,
ACCESSORIES OR DEVICES (OTHER THAN THOSE
AUTHORIZED BY THE MANUFACTURER) INTO, ONTO OR
IN CONJUNCTION WITH THE HEAT PUMP. YOU SHOULD
BE AWARE THAT THE USE OF UNAUTHORIZED COMPO-
NENTS, ACCESSORIES OR DEVICES MAY ADVERSELY
AFFECT THE OPERATION OF THE HEAT PUMP AND MAY
ALSO ENDANGER LIFE AND PROPERTY. THE MANUFAC-
TURER DISCLAIMS ANY RESPONSIBILITY FOR SUCH
LOSS OR INJURY RESULTING FROM THE USE OF SUCH
UNAUTHORIZED COMPONENTS, ACCESSORIES OR
DEVICES.
This booklet contains the installation and operating instructions
for your package heat pump. There are a few precautions that
should be taken to derive maximum satisfaction from it.
Improper installation can result in unsatisfactory operation or
dangerous conditions.
Read this booklet and any instructions packaged with separate
equipment required to 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 ship-
ment. Claims for damage, either shipping or concealed, should
be filed immediately with the shipping company. Check the unit
model number, heating size, electrical characteristics, and
accessories to determine if they are correct.
IV. EQUIPMENT PROTECTION FROM THE
ENVIRONMENT
The metal parts of this unit may be subject to rust or deteriora-
tion 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 sys-
tems, and various chemical contaminants from industries such
as paper mills and petroleum refineries are especially corro-
sive.
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.
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 waterfront.
3. Shielding provided by a fence or shrubs may give some
protection.
Regular maintenance will reduce the buildup of contami-
nants and help to protect the unit’s finish.
DISCONNECT ALL POWER TO THE UNIT BEFORE START-
ING MAINTENANCE. FAILURE TO DO SO CAN RESULT IN
SEVERE ELECTRICAL SHOCK OR DEATH.
1. Frequent washing of the cabinet, fan blade and coil with
fresh water will remove most of the salt or other contami-
nants 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.
