IMPORTANT FACTS
To better protect your investment and to eliminate unneces- sary service calls, familiarize yourself with the following facts:
WARNING: Improper installation, adjustment, alter- ation, service, maintenance, or use can cause explo- sion, ®re, electrical shock, or other conditions which may cause personal injury or property damage. Refer to this manual. For assistance or additional information con- sult a quali®ed installer, service agency, distributor, or branch office. The quali®ed installer or agency must use only factory authorized kits or accessories when modi- fying this product.
·Your heat pump system should never be operated without a clean air ®lter properly installed. Plan to inspect the ®lter periodically. A clogged air ®lter will increase operating costs and shorten the life of the unit.
·Supply-air and return-air registers should not be blocked. Drapes, furniture, and toys are some of the items commonly found obstructing grilles. Restricted air¯ow lessens the unit's efficiency and life span.
·Outdoor units must have unrestricted air¯ow. Do not cover the unit, lean anything against it, or stand upon it. Do not allow grass clippings, leaves, or other debris to accumulate around or on top of the unit. Maintain a 12-inch minimum clearance between the outdoor unit and tall grass, vines, shrubs, et cetera.
·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 Ð for instance, switching the electrical sup- ply power ON and OFF Ð may cause damage to the unit.
·Thermostat ``jiggling'' causes rapid-cycling, which is poten- tially damaging to the compressor. Do not move the tempera- ture selector on the thermostat for any reason for at least 5 minutes after the compressor has shut off.
·You may ®nd that you can maintain greater personal com- fort by running the fan continuously. ``Air pockets'' can form due to the structure of the building, placement of registers, et cetera. These air pockets may be too cool or warm for your liking. Continuous fan operation minimizes any temperature differences. Also, systems equipped with electronic air clean- ers and/or humidi®ers offer the added bene®ts of having the air continuously cleaned year-round, and humidi®ed during the winter season.
·Your heat pump will remove humidity from your home dur- ing 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, do not expect to see much drainage if you live in a very dry climate.
OPERATING YOUR HEAT PUMP
The operation of your heat pump system is controlled by the indoor thermostat. You simply adjust the thermostat and it maintains the indoor temperature at the level you select. Most thermostats for heat pump systems include temperature con- trol selector, FAN switch, and SYSTEM switch. EMER- GENCY HEAT control is usually provided with the SYSTEM switch.
The temperature control selector is a dial or button(s) that al-
lows you to establish the temperature that you wish to main- tain for your personal comfort. Some thermostats possess two temperature control selectors: one for setting the tempera- ture desired during the cooling cycle, and one to set the heat- ing operation temperature. Typical settings are 78 degrees Fahrenheit for cooling and 68 degrees for heating.
The FAN switch offers two options for controlling the blower: AUTO and ON. When set to AUTO, the blower will run dur- ing the time the heat pump is operating. When the FAN switch is set at the ON position, the blower will run continuously.
Typically, the SYSTEM switch on your thermostat offers the following selections: COOL, OFF, and HEAT. Your thermo- stat may also have a another selection, AUTO. The heat pump will not operate when the SYSTEM switch is set at the OFF position. With the SYSTEM switch set at COOL, your heat pump will operate in its cooling mode when the indoor tem- perature rises above the level that you wish to maintain. With the SYSTEM switch set at the HEAT position, your heat pump will provide warmth whenever the indoor temperature falls below the level that you have selected.
The AUTO selection found on some thermostats provides for automatic changeover between cooling and heating cycles. With the SYSTEM switch set in the AUTO position, the cooling mode is activated when the indoor temperature rises above the thermostat cooling temperature setting, or the heating mode will be activated when the indoor temperature drops below the thermostat setting for the heating cycle.
Depending on your typical winter heating needs, your home comfort system may include a supplementary heating source. The EMERGENCY HEAT switch provides for convenient se- lection between two heating modes. Your heat pump will op- erate when the switch is set at NORMAL. With the switch set at the EMERGENCY HEAT position, the heat pump will turn off and the supplementary heat source will be activated.
COOLING CYCLE
When operating in the cooling cycle, your heat pump will run until the indoor temperature is lowered to the level you have selected. On extremely hot days, your heat pump will run for longer periods at a time and have shorter ``off'' periods than on moderate days.
