Page 3 of 9GENERAL INFORMATIONThis manual is generic in nature and covers a wide range of heating and cooling products manufacturedby Bard Manufacturing Company. It is intended to be a general guide for care and operation of typicalsystems and covers the most important features you should be aware of and are responsible for as theuser of the equipment.Because our product offerings are so varied and can be equipped with many features and options, it isnot possible to cover all aspects of what your specific system may be configured for. Some systemsmay be quite simple in features to provide basic cooling and possibly heating, while others may alsoincorporate various ventilation technologies, dehumidification circuits, and many different internal controlsas well as room temperature controls. Therefore, you should request a detailed operation sequenceand explanation of any special features from your installer and/or Service Company, and also have theminstruct you as to any routine maintenance procedures you are responsible for.This manual will address the basic items that should apply to all systems, and will then be separated intospecific types of products to cover things unique to those product types.AIR FILTERSKeeping clean air filter(s) is the single most important responsibility of the user of the equipment. Eachtype of system must be equipped with an air filter(s) in the indoor circulating air system to clean theair, to keep the system itself clean for peak efficiency and capacity, and to prolong the useful life of theequipment. DO NOT operate the system without the proper air filters.Filters should be inspected at least monthly, and replaced or cleaned (depending on type) as needed.The useful life of an air filter can vary widely depending upon application and use of the equipment, andit is critical to monitor filter condition and establish an acceptable maintenance schedule. Failure to do sowill increase operating and repair costs, decrease capacity and efficiency, and shorten the service life ofthe equipment. A common symptom of a dirty filter in the cooling mode is a freeze-up of the indoor coil.The air filters used may be a disposable (throwaway) type or may be a cleanable type that can bethoroughly cleaned, rinsed and reused many times. It is important to make sure that the correct filtersize and type for your system is always used. If there is any question as to acceptable filter size or type,review the Installation Instructions for the specific equipment involved, if available. Otherwise, consultwith your installing dealer or Service Company.Most equipment can have the filters inspected and serviced by the user with no problems. In someinstances, because of equipment design or specific installation conditions, it may be necessary to havethis procedure done by a qualified service company. Have your installer or service company show youwhere the filter(s) are and demonstrate the service procedure or make arrangements for them to providethis service on an as needed basis.OUTDOOR COILThe outdoor coil must be kept clean and free of any airborne debris, which can accumulate over time.Large volumes of air are circulated over the coil, and airborne debris such as lint, dust, materials shedfrom trees, paper or other types of airborne material that can become airborne can collect on the enteringcoil surface.The outdoor coil must dissipate heat during the cooling mode, and for a heat pump must also absorbheat during the heating mode. If the coil is dirty and matted with debris, the airflow across the coil willbe reduced causing poor performance, increased operating run time and associated utility bills, and inextreme conditions can shorten the useful life of the equipment.
