General Information
The User's Application Guide covers a wide range of heating and cooling products manufactured by Bard
Manufacturing Company. It is intended to be a general guide for care and operation of typical systems and covers the
most important features you should be aware of and are responsible for as the user of the equipment.
Because our product offerings are so varied and can be equipped with many features and options, it is not possible to
cover all aspects of what your specific system may be configured for. Some systems may be quite simple in features to
provide basic cooling and possibly heating, while other systems may also incorporate various ventilation technologies,
dehumidification circuits and many different internal controls as well as room temperature controls. Therefore, you
should request a detailed operation sequence and explanation of any special features from your installer and/or service
company and also have them instruct you as to any routine maintenance procedures you are responsible for.
