5. Compressed Air Dryers are used to remove entrained moisture from compressed air supply systems and thus protect the various components and are designed such that routine maintenance is kept to a minimum Most parts are field replaceable but should major maintenance or repair be required please refer to Denco Limited or an authorised distributor NOTE This manual applies ONLY tothe C series of Compressed Air Dryers For actual model refer to serial plate fitted to the unit For other ranges refer to the respective manuals Warning These Dryers are only designed for use with compressed air at or below the design maximum pressure see Technical Data sheet s for maximum working pressures applicable These Dryers must NOT be used for drying any other gases or fluids at other pressures Operation of these Dryers using compressed air of a greater temperature than that specified will cause excessively high pressures in the refrigeration system which may be dangerous The air supplied to the dryer must be free of any corrosive or combustible gases or impurities Warranty The warranty will only be considered valid if the equipment supplied is installed commissioned and maintained in accordance with the instructions issued by Denco Limited Furthermore the Company will not accept any liability whatsoever should the Dryer be installed incorrectly or operated outside its stated design duties and operating conditions or improper use be made of the equi
