Instruction book Safety precautions Safety icons Explanation Danger to life Warning Important note Safety precautions, general General precautions All responsibility for any damage or injury resulting from neglecting these precautions, or non-observance of the normal caution and care required for installation, operation, maintenance and repair, even if not expressly stated, will be disclaimed by the manufacturer.
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.
Instruction book Also consult following safety precautions: Safety precautions during operation Safety precautions during maintenance or repair. These precautions apply to machinery processing or consuming air or inert gas. Processing of any other gas requires additional safety precautions typical to the application which are not included herein.

Instruction book flush abundantly with fresh water over the clothing until all refrigerant is flushed away; then seek medical first aid. 21. The following safety precautions are stressed when handling desiccant: • Take precautions not to inhale desiccant dust. • Check that the working area is adequately ventilated; if required, use breathing protection. •...
General description Introduction General views FX 13 up to FX 16 Introduction The FX air dryers remove moisture from compressed air by cooling the air to near freezing point. This causes water to condense. The condensate is automatically drained. The air is warmed up before leaving the dryer.
Instruction book Air system Air flow diagram Reference Name Evaporator Condensate separator Impurity trap Heat exchanger Digital dewpoint indicator 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.
Instruction book Refrigeration system Refrigerant flow diagram Reference Name Refrigerant compressor Condenser Evaporator Expansion capillary tube Refrigerant filter Liquid separator Description Compressor (1) delivers hot, high-pressure refrigerant gas which flows through condenser (2) where most of the refrigerant condenses. The liquid flows through the refrigerant dryer/filter (8) to capillary tube (7). The refrigerant leaves the capillary tube at evaporating pressure.
Instruction book Automatic regulation system Reference Name Cooling fan Hot gas bypass valve Maximum pressure switch Fan control switch Description The condenser pressure must be kept as constant as possible to obtain stable operation. Fan control switch therefore stops and starts the cooling fan (3). If, under partial or no load, the evaporator pressure drops below a certain level, the hot gas bypass valve opens and hot, high-pressure gas is fed to the evaporator circuit to prevent the evaporator pressure from dropping any further.

9. Then “rS” is fixed and “°C” blinks on display for ~10 seconds. The new service interval is now set. Freeze protection function (available with Remote Alarm function on FX 13 to FX 16) Once the digital controller detects a dewpoint temperature below -2°C during more than 2 minutes, (L2 Alarm), it switches off the refrigerant compressor.
To keep the compressed air net free of condensate, start the dryer before starting the compressor and stop the compressor before stopping the dryer. Procedure FX 13 up to FX 16 Step Action If installed, close the dryer by-pass valve. See Installation proposal.
Instruction book During operation Procedure FX 13 up to FX 16 Regularly check: • The pressure dewpoint on the digital controller (1). The pressure dewpoint will deviate from nominal if the air inlet conditions or volume flow differ from nominal.
