SAFETYCONSIDERATIONS
Recognize safety information. This is the safety-alert symbolz_ x . When you see this symbol on unit or in instructions and manuals, be alert to
potential for personal iniury.
Understand the signal words DANGER, WARNING, and CAUTION. These words are used with the safety-alert symbol. DANGER identifies the
most serious hazards which will result in severe personal injury or death. WARNING signifies hazards which could result in personal injury or
death. CAUTION is used to identify unsafe practices which would result in minor personal injury or product and property damage. NOTE is used
to highlight suggestions which will result in enhanced installation, reliability, or operation.
z_ WARNING: Improper installation, adjustment, alteration, service, maintenance, or use can cause explosion, fire,
electrical shock, or other conditions which may cause serious injury, death or property damage. Consult a qualified installer,
service agency, or your distributor or branch for information or assistance. The qualified installer or agency must use
factory-authorized kits or accessories when modifying this product.
YOUR COMFORT SYSTEM
PROCEDURE I--IDENTIFYING YOUR SYSTEM
Take the time to i_amiliarize yourself with your packaged heat pump type of system. This knowledge will be of use in understanding the basic
operation of your new heat pump. The unit has a rating plate affixed to it which provides necessary information for specific identification of a unit.
You should familiarize yourself with the product, model, and serial numbers listed on each rating plate. Record them for furore reference in the
space provided at the end of this booklet.
IMPORTANT FACTS
Fig. 2--Typical Installation
To better protect your investment and to eliminate unnecessary calls, familiarize yourself with the fbllowing facts:
i. Your heat pump system should never be operated without a clean air filter properly installed. Plan to inspect the filter periodically. A
clogged air filter will increase operating costs and shorten the life of the unit.
2. Supply-air and return-air registers should not be blocked. Drapes, furniture, and toys are some of the items commonly found obstructing
registers. Restricted airflow lessens the unit's efficiency and life span.
3. The outdoor unit must have unrestricted airflow. Do not cover the unit, lean anything against it, or stand on it. Do not allow grass clippings,
leaves, or other debris to accumulate around on top of the unit. Maintain a 12-in. minimum clearance between the outdoor unit and tall grass,
vines, shrubs, etc.
4. Your multipurpose indoor thermostat is the control center for your heat pump system. You should familiarize yourself with its proper
operation. Attempting to control the system by other means for instance, switching the electrical supply power ON and OFF may cause
damage to the unit. (See Fig. 4 and 5.)
5. During heating, increasing the thermostat setting more than 2 degrees may cause the supplemental heaters to be turued on for a short period
of time to satisfy the thermostat. Needless use of the supplementary heat reduces potential energy savings.
6. You may find that you can maintain greater personal comfort by running the fan continuously. "Air pockets" can form due to the structure
of the house, placement of registers, etc. air pockets may be too cool or warm for your liking. Continuous fan operation minimizes any
temperature differences. Also, systems equipped with electronic or mechanical air cleaners and/or humidifiers offer the added benefits of
having the air continuously cleaned year-round and humidified during the winter season.
7. A system equipped with a heat or energy recovery ventilator offers the advantage of exhausting stale air fi'om the home and allowing fresh
air in fi'om the outdoors while minimizing heat loss.
8. Your system may also be equipped with a zoning system which allows individual control over the temperatures of separate areas of your
home.
9. Your heat pump will remove humidity from your home during the cooling season. After a few minutes of operation, you should be able
to see water trickle from the condensate drain. Check this occasionally to be sure the drain system is not clogged. Of course, don't expect
to see nmch drainage if you live in a very dry environment.
10. During the heating cycle, air from your registers may seem cooler than you might first expect. This is because your heat pump delivers a
constant flow of air at around 90F to 105°F instead of sudden bursts of hot air as with a conventional furnace. This air may feel cooler
because it is slightly less than your skin temperature. However, it is sufficiently warm to keep you comfortable.
