This is the safety - alert symbol . When you see this symbol on the unit and in instructions or manuals , be alert to the potential for personal injury . Understand the signal words DANGER , WARNING , and CAUTION . These words are used with the safety - alert symbol . DANGER will result in severe personal injury or death . WARNING signi�es hazards which could identi�es the most serious hazards which may result in minor personal injury or product result in personal injury or death . CAUTION is used to identify unsafe practices which and property damage . NOTE is used to highlight suggestions which will result in enhanced installation , reliability , or operation . ! WARNING : ELECTRICAL SHOCK , FIRE , EXPLOSION , PERSONAL INJURY HAZARD Improper installation , adjustment , alteration , service , maintenance or use could result in personal injury , death , and / 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 . ! WARNING : ELECTRICAL SHOCK , UNIT OPERATION AND SAFETY HAZARD Failure to follow this warning could result in personal injury , death , and / or property damage . Read and follow all instructions and warnings , including labels shipped with or attached to unit before operat - ing your new heat pump . IMPORTANT FACTS To better protect your investment and to eliminate unnecessary service calls , familiarize yourself with the following facts : • 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 obstruct - ing grilles . Restricted airflow lessens the unit’s ef�ciency and life span . • The outdoor unit must have unrestricted airflow . 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 - in . minimum clearance between the outdoor unit and tall grass , vines , shrubs , etc . • 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 . • During heating , increasing the thermostat more than 2 degrees may cause the supplemental heaters to be turned on to satisfy the thermostat . Needless use of the supplementary heat reduces potential energy savings . • You may �nd 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 . 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 cleaners 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 during the cooling season . After a few minutes of operation , you should be able to see water trickle from the condensate drain of the indoor cooling coil . Check this occasionally to be sure the drain system is not clogged . Of course , don’t expect to see much drainage if you live in a very dry environment . NOTE TO INSTALLER:THIS MANUAL MUST BE LEFT WITH THE EQUIPMENT USER .

• During the heating cycle , air from your registers may seem cool . This is because the air is being delivered at a higher velocity and a more constant flow than air supplied by a conventional furnace.Also , your heat pump supplies air at 90 ° to 105 ° F instead of in sudden bursts of hot air as with a conventional furnace . The air may feel cool because it is slightly lower than your body temperature . However , it is suf�ciently warm to keep you comfortable . • Ice or frost will tend to form on the outdoor coil during the winter heating operation.Your heat pump is designed to automatically melt the ice . When in this defrost cycle , it is normal for steam or fog to rise from the outdoor unit . Do not be alarmed ! 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 . Refer to the thermostat operating instructions for information on how to operate your thermostat . COOLING CYCLE When operating in the cooling mode , 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 . Lowering the setpoint of your thermostat will not cause your heat pump to cool faster . The following are typical conditions that add extra heat and / or humidity to your home.Your cooling unit will work longer to keep your home comfortable under these conditions : • Entrance doors are frequently opened and closed • Laundry appliances are being operated • A shower is running • More than the usual number of people are present in the home • More than the normal number of electric lights are in use • Drapes are open on the sunny side of the home HEATING CYCLE With HEAT selected , the heating section of your home comfort system will operate until room temperature is raised to the level you have selected . Of course , the heating unit will have to operate for longer periods to maintain a comfortable environment on cooler days and nights than on moderate ones . DEFROST CYCLE When your heat pump is providing heat to your home and the outdoor temperature drops below 45 ° F , moisture may begin to freeze on the surface of the outdoor coil . If allowed to build up , this ice would impede airflow across the coil and reduce the amount of heat absorbed from the outside air . So , to maintain energy - ef�cient operation , your heat pump has an automatic defrost cycle . The defrost cycle starts at a preset time interval of 90 minutes , although , it may be reset to either 30 or 60 minutes . Defrost will start at the preset time only if the ice is suf�cient to interfere with normal heating operation . After the ice is melted from the outdoor coil , or after a maximum of 10 minutes in the defrost mode , the unit will automatically switch back to normal heating operation . Do not be alarmed if steam or fog appears at the outdoor unit during the defrost cycle . Water vapor from the melting ice may condense into a mist in the cold outside air . During certain weather conditions such as heavy snow and freezing rain it is not uncommon for ice to build up on the outdoor unit grille . This is normal for these weather conditions . Do not attempt to remove the ice from the outdoor unit grille . This condition will not affect the proper function of the unit and will clear within a few days . EMERGENCY HEAT The EMERGENCY HEAT setting on your thermostat refers to any supplementary heating appliance that may be included in your home comfort system . Operation of the EMERGENCY HEAT source may be required if heating demands exceed the capacity of the heat pump , or if the heat pump malfunctions . During the heating season , switch to EMERGENCY HEAT if the electricity to your outdoor unit has been off for more than 30 minutes for any reason ( i.e . , power outage ) . Leave the switch in the EMERGENCY HEAT mode for an amount of time equal to that during which the power was off . It isn’t necessary to exceed 12 hours . If you cannot determine how long the power has been off , leave the switch in the EMERGENCY HEAT position for 8 hours . The EMERGENCY HEAT switch is effective only when HEAT or AUTO is selected .

PERFORMING ROUTINE MAINTENANCE With the proper maintenance and care , your heat pump unit will operate economically and dependably . Maintenance can be accom - plished easily by referring to the following directions . However , before performing maintenance , consider these important safety precautions . ! WARNING : ELECTRICAL SHOCK HAZARD Failure to follow this warning could result in personal injury , death . Disconnect all electrical power to the heat pump before removing access panels to perform maintenance . Discon - nect power to both the indoor and outdoor units . Note : There may be more than 1 electrical disconnect switch . ! CAUTION : CUT HAZARD Failure to follow this caution may result in personal injury . Although special care has been taken to minimize sharp edges in the construction of your unit . Be extremely careful when handling parts or reaching into the unit . Use care and wear appropriate protective clothing and gloves when handling parts . CHECK THE AIR FILTER A dirty air �lter will cause excessive strain on the compressor and blower motor . This can cause the components to overheat and automatically shut down . In the extreme , the components will fail and need to be replaced . To avoid inef�cient or failed operation of your unit , CHECK THE FILTER ( S ) EVERY 3 TO 4 WEEKS . Replace �lter ( s ) when necessary , or clean the �lter ( s ) if you have the washable type . Disposable �lters should be replaced by similar , new �lters of the same dimensions . Reusable , washable �lters should be washed in a solution of cold water and mild detergent , then rinsed and thoroughly dried . THE FILTER MUST BE COMPLETELY DRY BEFORE BEING REINSTALLED . To avoid prolonged shutdown of your unit while a �lter is drying , you should have an extra �lter on hand . This would allow you to rotate between the two �lters with minimal downtime for your comfort system . Extra �lters may be purchased from your dealer . There are no �lters in the outdoor unit of a split system . If your indoor unit is a gas or oil furnace , refer to your furnace User’s Manual for �lter location and procedures for replacement or cleaning . If your system includes an indoor fan coil unit , the �lter may be located in the unit where it connects with the return - air duct or plenum . ( See Fig . 1 . ) Remove the �lter cover plate by sliding latches toward center of plate . Lift �lter to clear lower flange . Filter is spring - loaded and will pop out . Reinstall �lter , being certain to secure �lter behind lower flange . When reinstalling cover plate , secure plate behind upper flange then slide tabs outward . Fig . 1 — Removing Filter from Fan Coil Unit The indoor fan coil unit may be located in the attic . In this instance the �lter may be located behind the return air grille . Access the �lter by removing the return air grille . 3
