Page 7: Safety Precautions During Installation
Instruction book Safety precautions during installation Precautions during installation 1. The dryer must only be lifted using suitable equipment and in accordance with the applicable safety regulations. Loose or pivoting parts must be securely fastened before lifting. It is strictly forbidden to dwell or stay in the risk zone under a lifted load. -
Page 8: Safety Precautions During Operation
Instruction book 16. If no safety valve is present in the air net close to the desiccant dryer (e.g. safety valve of compressor), full flow safety valves must be installed on the dryer vessels. 17. If the maximum pressure of the compressor is higher than the design pressure of the dryer, a full flow safety valve must be installed between the compressor and the dryer in order to blow off the excessive pressure. -
Page 9: Safety Precautions During Maintenance Or Repair
Instruction book 9. If warm cooling air from dryers is used in air heating systems, e.g. to warm up a working area, take precautions against air pollution and possible contamination of the breathing air. 10. Do not remove any of, or tamper with, the sound dampening material. 11. -
Page 10: Dismantling And Disposal
Instruction book 16. Before clearing the machine for use after maintenance or overhaul, check that operating pressures, temperatures and time settings are correct. Check that all control and shut-down devices are fitted and that they function correctly. 17. Protect the motor, electrical and regulating components, etc. to prevent moisture from entering them, e.g. - Page 11 Instruction book The equipment is labelled in accordance with the European Directive 2012/19/EU with the crossed- out wheelie bin symbol. At the end of life-time of the electric and electronic equipment (EEE) it must be taken to separate collection. For more information check with your local waste authority, customer center or distributor. Disposal of other used material Used filters or any other used material (e.g.

Instruction book Figure 2: Open view Refrigerant compressor Condenser Motor fan Evaporator Condensate drain Hot gas bypass valve Refrigerant filter Expansion capillary tube Introduction The FX air dryers remove moisture from compressed air by cooling the air to near freezing point. This causes water to condense. -
Page 14: Refrigeration System
Instruction book Reference Name Evaporator Condensate separator Impurity trap Heat exchanger Digital controller Condensate drain Description Compressed air enters heat exchanger (10) and is cooled by the outgoing cold, dried air. Water in the incoming air starts to condense. The air then flows through heat exchanger/evaporator (10 and 4) where the refrigerant evaporates, causing the air to be cooled further to close to the evaporating temperature of the refrigerant. -
Page 15: Automatic Regulation System
Instruction book The liquid flows through the refrigerant dryer/filter (8) to capillary tube (7). The refrigerant leaves the capillary tube at evaporating pressure. The refrigerant enters evaporator (4) where it withdraws heat from the compressed air by further evaporation at constant pressure. The heated refrigerant leaves the evaporator and flows through the liquid separator (9) back to the compressor (1). -
