Denco C120-3, Руководство по эксплуатации, Страница: 3 / 32

Important
The refrigerant available on the C series of Compressed Air Dryers is Refrigerant R134a or Refrigerant
R407C . It is imperative that refrigerants are not mixed. A label is fixed to each compressor, which identifies the
refrigerant being used within the unit, and that refrigerant ONLY should be used in the dryer. R134a & R407C
are ozone benign refrigerants and meet the requirements of the revised “Montreal Protocol”. These refrigerants
require the use of ESTER oil within the system and not MINERAL oil as used with R22 systems, and therefore
again these oils must NOT be mixed.
Introduction
The Denco C series of 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 to the 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 equipment.
