1. GENERAL INFORMATION

1.1 Functional description

FST refrigerated air dryers remove moisture from compressed air. Moisture is detrimental to pneumatically operated appliances, controls, instruments, machinery and tools.

Compressed air enters the patented aluminum heat exchanger where it is cooled down to the dew point temperature in two different stages: In the first air/air sector compressed inlet air is cooled thanks to the colder compressed air coming out counterflow from the condensate separator. In the second refrigerant / air sector, compressed air temperature is further lowered to the dew point temperature. During this two stages almost all the oil and water vapours contained in compressed air are condensed to liquid and successively be separated from the compressed air in the condensate separator and drained out by the automatic drain. At this point the obtained cold air re-enters counterflow the initial air / air exchanger and it is reheated by the inlet hot air with the consequence of energy recovering and also reduction of the relative humidity contained in the outflowing air.

This dryer can be easily installed into various pneumatic systems in which dry air is required or desired. Please refer to Principles of Operation for complete operating details.

The dryer comes provided with all the control, safety and adjustment devices, therefore no auxiliary devices are needed. A system overload not exceeding the maximum operative limits can worsen the operational performance of the dryer (high

dew point), but it will not affect its safety. The electric diagram (attachment B) shows the minimum protection degree IP 42.

Improper grounding can result in electrical shock and can cause severe injury or death. This product must be connected to a grounded, metallic, permanent wiring system or an equipment-grounding terminal or lead on the product. All grounding must be performed by a qualified electrician and comply with national and local electrical codes. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. Ground must be established with a bare grounding wire sized according to the voltage and minimum branch circuit requirements. Ensure good bare metal contact at all grounding connection points, and ensure all connections are clean and tight. Check grounding connections after initial installation and periodically thereafter to ensure good contact and continuity has been maintained. Check with a qualified electrician or service technician if the grounding instructions are not completely understood, or if in doubt as to whether the product is properly grounded.

1.2 Use of the machine in safe conditions

This system has been designed and manufactured in compliance with the European safety directive in force and UL/ULC, therefore any installation, use and maintenance operations must be performed respecting the instructions contained in this manual.

Because an air dryer is pressurized and contains rotating parts, the same precautions should be observed as with any piece of machinery of this type where carelessness in operation or maintenance could be hazardous to personnel. In addition to obvious safety rules that should be followed with this type of machinery, safety precautions as listed below must be observed.

1. Only qualified personnel shall be permitted to adjust, perform maintenance or repair this air dryer.

2. Read all instructions completely before operating unit.

3. Pull main electrical disconnect switch and disconnect any separate control lines, if used, before attempting to work or perform maintenance on the unit.

4. Do not attempt to service any part while machine is in an operational mode.

5. Do not attempt to remove any parts without first relieving the entire air system of pressure.

6. Do not attempt to remove any part of the refrigeration system without removing and containing refrigerant in accordance with the EPA and local regulations.

7. Do not operate the dryer at pressures in excess of its rating.

8. Do not operate the dryer without guards, shields and screen in place.

9. Inspect unit daily to observe and correct any unsafe operating conditions.

This dryer is designed to work only with compressed air. For a different use, please contact your distributor FST.

2.3 Information about remaining risks of the equipment

Fire:

This equipment, in accordance to EN-378-2, isn’t supplied with freon drain safety valve. In case of fire it is preferable to use fire extinguishers or extinction systems basically composed of powder or foam or carbon dioxide: it is possible to cool the equipment thanks to nebulized water. Avoid the massive use of water because, in case of freon gas leak, the chemical reaction can cause caustic effects, even if small. In any case it is necessary to cool down the ambient and/or the equipment’s temperature and before any intervention wait until the temperature has been reduced. Therefore it is preferable to insert this equipment into the Fire Prevention and Factory Safety Plan. Arrange adequate actions capable to prevent and fight the possible risk.

Dispersion of freon gas in the ambient:

the refrigerant means is toxic only if inhaled at high concentration: it is necessary to provide an adequate ventilation in the room where the equipment is installed. In any case check the scheme showing the values and the risk sentences.

Excessive pressure on the compressed air side:

this equipment isn’t supplied with safety devices on the compressed air side. The safety devices on the compressed air side must be carried out by the installer. Such devices will have to be carried out according to the applicable National Norms and to the limits mentioned in this Manual.

Ozone layer deterioration:

The adoption of HFC freon reduce to the minimum ozone layer deterioration and greenhouse effect.

3.0 INSTALLATION

3.1 Acceptance and handling

Upon receiving your FST air dryer, please inspect the unit closely. If rough handling is detected, please note it on your delivery receipt, especially if the dryer will not be uncrated immediately. Then obtain the freight carrier's signed agreement to any noted damages: this is a precondition for any insurance claims by the customer.

It is mandatory to keep the dryer always in vertical position, as indicated by the symbols present on the packaging. For handling, use devices having sufficient capacity for the weight of the machine.

Remove the packaging after having positioned the dryer in the installation site. For unpacking, refer to section 3.3. Under no circumstances should any person attempt to lift heavy objects without proper lifting equipment (i.e., crane, hoist, slings or fork

truck). Lifting any unit without proper lifting equipment, may cause serious injury. Use fork lift channels where provided.

3.2 Storage and installation location

If not in use, the dryer can be stored in its packaging in a dust free and protected site between 32°F (0°C) and 120 °F (50 °C), and a specific humidity not exceeding 90 %. Should the stocking time exceed 12 months, please contact your local FST authorized distributor.

If the dryer is not used, it will be placed in a site with the following conditions:

 The machine must be protected from atmospheric agents and not directly exposed to sun light.  A seating base flat and capable to hold the weight of the machine.  Ambient temperature complying with the nominal data of the dryer.  The dryer should be located in a clean area, without forced air draft that can affect the fan control system.  Make sure to leave sufficient clearance (40 inches, 1 m) around the dryer in order to allow an adequate cooling

of the machine and for maintenance and/or control operations.

The incoming air must be free from smoke or flammable vapours which could lead to explosion or fire risks.

3.3 Unpacking

The packaging is made of carton or of cellophane. We recommend that you keep the original packaging for the device in case it has to be transported to another location or sent to a service center. Dispose the various packaging materials in compliance with the relevant rules locally in force.

• unpack the device, removing the strapping from the carton. Always wear safety gloves when using scissors or other tools to cut the straps or the cellophane;

• remove the carton or the cellophane;

• in case it’s necessary another handling of the device, refer to section 3.1;

• remove the pallet (if present);

• remove the operating manual, accessories and key from the device.

3.4 Installation

Before attempting any installation operation, make sure that

 No parts of the air system are under pressure.  No parts of the system are electrically powered.  Tubing to be connected to the dryer are free of impurities.  The pipes to be connected to the dryer does not weigh on the device.  All interconnecting piping has been tightened.

After having verified the points listed above, you can proceed to the installation of the machine.

1. Connect the dryer to the compressed air lines. If not already existing, we suggest to install a by-pass allowing to isolate the machine from the plant, thus to facilitate eventual maintenance operations.

2. Perform the electrical connection in accordance with any local laws and regulations after reviewing the dryer electrical specifications and wiring diagram.

3. Check the condensate drainage assembly, and connect the drain flexible hose to the draining line, keeping in mind that the condensate separated by the dryer may contain oil, therefore, in order to dispose of it in

compliance with the local rules in force, we suggest installing a water-oil separator having adequate capacity.

4. Power the dryer after having checked that the nominal voltage and line frequency are constant and matching the nominal values of the machine. The user must provide the installation with an adequate line protection and a ground terminal complying with the electrical rules locally in force.

DMN FST Kaeltetrockner DFLO150-1360 (Rev-06) –EN-20121100

Page 6

In order to optimise the use of the dryer, we suggest to place it in such a way that all the control instruments of the machine will result easily visible.

A suitably sized prefilter must be installed before the dryer. Failure to install and maintain a proper prefilter will void the dryer warranty. The rating for this filter must be at least 10 micron.

It is necessary for the user to install a protective device (a safety accessory) to protect the equipment under pressure from the risk of exceeding the maximum allowable pressure (PS); it is necessary to install a protective device to protect the equipment at high temperature from the risk of exceeding the maximum allowable temperature.

4.0 START-UP

• Make sure that intake and outtake valves are closed, switch on the devices (1S1).

• TO START THE DRYER IT IS NECESSARY TO PRESS AND HOLD THE ON/OFF BUTTON FOR AT LEAST FOR 3 SECONDS

• THERE IS A DELAY BEFORE THE DRYER WILL START AFTER THE DRYER IS TURNED ON, IN ORDER TO WARM UP COMPRESSOR OIL.

• IF THE UNIT FAILS TO START MAKE SURE THAT PHASES ARE CONNECTED CORRECTLY.

• Allow some minutes for the dryer to run at full speed, i.e. until the displayed value on the temperature display is within the field of good operation

(about 3°C).

• Now open the outlet air valve and then open gradually the intake air valve. In this way, the plant is gradually pressurized.

• If the plant is overloaded over the max. use limits (see technical data), the dryer's performance will be remarkably lower but safety will not be in

danger.

5.0 MAINTENANCE

Attention! Perform pressure test with inert gases only (helium, nitrogen).

5.1 Weekly

Check visually if the condensate is properly drained.

5.2 Monthly

Clean prefilter to remove any possible dirt on the inner filtering element. Perform the following after stopping the compressed air flow by closing the intake and outtake valves.

5.3 After 6 months

Isolate the machine before performing the following. According to the room temperature quality and when summertime begins, clean the condenser to remove possible scales or deposits the might decrease its performance. Check that the compressor power consumption values fall within the range detailed on the machine plate (see compressor product label).

In case of replacement of one or more components of the device, disposed it along the eventual packaging of the replacement part, as reported in section 9.0.

6.0 CONTROL PANEL

The machines in this series are equipped with an electronic controller for the adjustment of the operating parameters. Adjustments can be made using the digital panel, located on the dryer’s front panel. Please note that the SET POINT & other control parameters

have been optimized and factory set. Although the set point value can be displayed, the ability to alter these factory settings via the digital interface on the front panel has been removed to eliminate the possibility of unit damage caused by improper settings.

DMN FST Kaeltetrockner DFLO150-1360 (Rev-06) –EN-20121100

Page 15

Remote ON/OFF digital input is configured as follow: close contact = dryer ON.

•

When the dryer is switched off using remote OFF command, the controller shows on upper display line the message “OFF” and the remote ON/OFF led blinks.

The remote OFF function disables the ON function from the dryer’s control board (until the ON function is activated from remote ON/OFF switch). To restart the dryer it’s necessary to operate on the remote control.

The activation of the above function is at the user’s discretion. The user will purchase all necessary installation materials himself. Any operation which needs access to the dryer must be carried out by qualified personnel.

6.10.2 Remote signalling alarm

The dryer control board is supplied complete with a digital output configured as remote signalling alarm. This digital output is controlled by a relays configured as normally open: when an alarm is detected, these relays close a circuit. The status of the relays can be inverted, if necessary, using AL18 programming parameter (See 6.6.2 Parameters table). Proceed as follows to activate a remote alarm output:

1. The User must provide a signaller in compliance to output relays electrical features (solenoid coil, light bulb, acoustic signaller, ...).

2. Disconnect the dryer from the electrical supply and open the electrical box.

3. Connect the signaller on “REMOTE ALARM” terminal blocks (See electric wiring diagram).

8.2 INTEGRATED NO LOSS DRAIN Level sensor (Reed) for integrated No loss drain

The level sensor allows the electronic controller to activate the solenoid valve only if need, without compressed air loss, measuring the condensate level into the separator tank.

If the float remains blocked in its open position, causing loss of compressed air, the electronic controller switches to timed mode until the level sensor restores the normal operation.

Cleaning of the level sensor.

8.3 NO LOSS CONDENSATE DRAIN

The electronic drain discharge is supplied completely with an output

Electronic drain discharge is the new discharger applicable to any compressed air systems. It eliminates the condensate without wasting compressed air. Electronic drain discharge starts automatically, without the need of any adjustment. The condensate discharge occurs to the use of an electronic sensor, which detects the amount of condensate in the integrated water collecting tank. The level sensor drives start and duration of the drainage, so preventing any wasting of compressed air. At the end of installation, put the system under pressure and push the TEST key repeatedly to eliminate the air bubbles contained in the discharger inlet fittings. Please refer to the attached CD of the discharger for complete instructions. To this discharger will be applied the Beko warranty conditions.
