1. Fields of applicationThe FINO refrigeration dryer removes humidity fromthe compressed air by cooling it down to nearly free-zing point. This condenses the humidity in the com-pressed air. The formed condensate is expelledautomatically. The air is heated prior to leaving therefrigeration dryer. This reliably protects against cor-rosion damage and thus extends the service life of alltechnical equipment and instruments.

2. Safety precautionsThe air generated by the refrigeration dryer does nothave breathing air quality. To generate breathing airquality, the compressed air needs to be cleaned inaccordance with applicable laws and standards.Never play with compressed air. Do not direct the jetof compressed air at the skin or third parties. Underno circumstances use compressed air to remove dirtfrom clothes. Do not walk or stand on the refrigera-tion dryer or its components.

The refrigeration dryer contains refrigerants:• Do not inhale refrigerant vapours under any

circumstances. Ensure that the work room isadequately ventilated, otherwise use breathingprotection.

• Direct contact with refrigerants causes frostbiteof the skin. Always wear refrigerant-resistant gloves to prevent localised hypothermia. If theskin comes into contact with refrigerants, rinsewith water. If liquid refrigerant penetrates throughclothes to the skin, then under no circumstancesshould the clothes be removed, instead applycopious amounts of clear water to the clothesuntil the entire refrigerant has been rinsed off,then seek medical attention.

3. Commissioning3.1 Prior to commissioningRead the instructions for use carefully and keepthese readily available.The device is to be checked on one's own responsi-bility for operational safety prior to use. Defectiveparts are to be replaced immediately. Prior to con-necting the piping, remove all stoppers, caps orbags of drying agents. Select air hoses and distribu-tor pipes and connections of the correct size corres-ponding to the operating pressure.

3.2 Location

Position the refrigeration dryer indoors on an even,load bearing surface. Keep a minimum distance of1.5 m between the top of the device and the room'sceiling. Keep a minimum distance of 1.5 m betweenthe back of the compressor and the room's walls (1).Choose the position of the refrigeration dryer suchthat the ambient air is free of dust and the minimumand maximum ambient temperature are maintained(cf. Technical data » Limit values). The intake airmust not contain any inflammable particles, forexample, solvents, which could explode or igniteinside the device. Do not block the air intake underany circumstances. Ensure that loose-fitting clothingcannot be sucked in.Ensure that the pipelines can expand at heat and arenot positioned near combustible material.No external forces may act on the air outlet valve.The connected pipelines must be free of tension.The electrical connections must comply with applica-ble regulations. The refrigeration dryer must begrounded and secured against short-circuiting withfuses for all phases. A lockable circuit breaker (2)must be installed in the immediate vicinity of thedevice.

3.3 InstallationProvide the dryer with the voltage given on the typeplate via a power cable (1). Lay the condensate drainhose (2) to the condensate collector via a funnel forvisual inspection of the effluent.Attach an air inlet line and an air outlet line (5) inclu-ding seal (6) to the marked inlet (3) and outlet pipes(4) of the refrigeration dryer. Seal the ends of thevalves well with Teflon tape and screw a coupling (7)to each. Connect the compressed air lines.

4. Commissioning4.1 Safety precautionsDo not operate the machine outside the limit values.Keep all sound-proofing covers closed during opera-tion. Wear hearing protection if a sound-proofingcover has to be opened for a short time, e.g. to per-form routine inspection.Check regularly that:• all panels are fitted and secured safely,• all hoses and pipes in the machine are tight,• all securing elements are tightened firmly,• the safety valves and other overpressure devices

are not blocked through dirt or paint,• the air outlet valve and air network is free of wear

or damage.

4.2 Operation

pressure dew point indicator (1)ON/OFF switch of the dryer (2)

To ensure best efficiency, do not operate theON/OFF switch of the dryer repeatedly over a shortperiod of time. Do not restart the dryer before at least 5 minutes after switching off to allowpressure compensation.Start the dryer before the compressor andswitch off after the compressor to avoid formingcondensate in the compressed air network.

Starting:1. Operate the ON/OFF switch of the dryer.2. Open the air inlet valve.3. Open the air outlet valve

approx. 5 minutes later.4. The nominal dew point is reached

approx. 10 minutes later.

Stopping:1. Close the inlet and outlet valves of the dryer.2. Operate the ON/OFF switch of the dryer.

The dryer stops.

The following should be checked regularly:• the pressure dew point indicator on the operating

panel. Under conditions deviating from the nominal conditions (air inlet conditions or volumeflow), the pressure dew point will also deviatefrom the nominal value.

• whether condensate flows out via the condensatedrain. The volume depends on the operating conditions.

5. MaintenanceAll maintenance work should be carried out aftercooling of the machine.Close the inlet and outlet valves and release thepressure in the dryer by operating the test key on thecondensate drain. Then switch off the power voltage.Open the circuit breaker to prevent unintentionalstarting.Only perform maintenance work and repairs withsuitable tools and safety wear. Only use originalspare parts. Do not perform repairs in the refrigera-tion dryer yourself, contact the dealer.Observe cleanliness during all maintenance work.Cover components and exposed openings with cleancloths, paper or tape to keep dirt away. Under no cir-cumstances should corrosive or inflammable sol-vents or carbon tetrachloride be used for thecleaning of components. Protect the motor andelectrical components against moisture, for exam-ple, during steam cleaning.Under no circumstances should welding or othermodifications be carried out on the pressure vessel.If overheating of an internal component issuspected, stop the machine. Do not open anypanels until the machine has cooled down sufficient-ly to avoid the risk of spontaneous inflammation ofthe oil vapours at the air inlet.Under no circumstances use a light source with openflame to inspect the interior of the device.Ensure that no tools or other loose parts are left in oron the machine.Prior to releasing the refrigeration dryer for renewedoperation, ensure that the settings for operatingpressure, temperature and time are correct. Checkwhether the control and cut-off devices are installedand in perfect working condition.

6. CleaningAlways keep the refrigeration dryer clean.Take the same safety precaution before cleaning asthose before maintenance.Clean the filter once a week. To this purpose, remo-ve the filter from the automatic condensate drain.Clean from the inside to the outside with an air jet.Then re-install the filter.Brush or air-blast the ribbed surface of the conden-ser once per month. Do not clean with water or solvents.

7. StorageStore the device in its original packaging vibration-free in a dust-free and dry place at a temperaturebetween 0 °C and 40 °C.

11. Problem identification and handling1. The pressure dew point is too high.• The air intake temperature is too high.

Install pre-cooler.• The ambient temperature is too high.

Position the dryer at a cooler place.• The air intake pressure is too low.

Adjust pressure switch.• Dryer capacity exceeded. Reduce air flow.• Insufficient refrigerant. To be checked and

corrected by manufacturer.

2. The condenser pressure is too high or too low.• The fan is not working. Change fan motor.• The condenser is blocked on the outside.

Clean condenser.

3. The compressor misfires or does not start.• The power supply to the compressor is

interrupted. Check and rectify if required.• Thermal protection of the refrigerant compressor

motor has been triggered. Reset thermostat protection.

• Dryer has been restarted too quickly, not enough time for pressure compensation. Wait several minutes and restart.

4. The condensate drain does not work.• Drain system blocked. Have system checked by

manufacturer.
