Assembly, commissioning, and operation

CAUTION
The danger of injury if assembled under pressure or voltage!
Assembling when under pressure or electrical voltage can lead to injuries and damage to the product or system components.

1. Make sure that the relevant system component is without pressure and voltage before you assemble the product.
2. Protect the system against being restarted.

CAUTION
Sudden pressure increases during commissioning!
If no SSU filling valve is used, the system will suddenly be under pressure during commissioning! This may result in dangerous erratic cylinder motions.

• When commissioning a system, make sure that the cylinders are in their end position. For cylinders not in the end position, make sure they do not present any danger.

CAUTION
The system is operating under pressure!
Incorrect installation may damage the maintenance unit/maintenance equipment and cause serious injury.

• Before commissioning, check that all connections, ports, and maintenance equipment have been correctly installed.

4.1 Filter
The FLS filter is a maintenance unit component:
The passing compressed air will be roughly freed of solid contaminants and condensation water via centrifugal force and the filtration effect.

Steps at a glance

1. Mounting fastening elements. See → Fig. 7.
2. Connect the filter to the tubing system. See → Fig. 9.
3. Operating the condensate drain. See → Fig. 1, → Fig. 2, → Fig. 3.

4.1.1 Semi-automatic condensate drain

CAUTION
Potential impairment of compressed air system by condensate!
In the case of the semi-automatic condensate drain, condensate is only discharged when the reservoir is without pressure. If in operation for an extended period, the condensate may exceed the maximum filling level and find its way into the compressed air system. This may result in damage to the compressed air system.

1. Regularly check the filling level in the reservoir.
2. Drain condensate manually once it reaches the maximum filling level.
3. Do not let the condensate run off into the surroundings.

See → Fig. 1.
The semi-automatic condensate drain closes at a pressure > 1.5 bar and opens at an operating pressure < 1.5 bar.
Setting the automatic mode:

If the drain screw is screwed in completely, the automatic drainage is blocked.

• Open the drain screw by turning it all the way to the left.

You may leave the screw one turn deep in the thread or remove it completely.

4.1.2 Fully automatic condensate drain
See → Fig. 2.
“Normally open” configuration
In the “normally open” configuration, the condensate drain closes at a pressure > 1.5 bar and opens at an operating pressure < 1.5 bar.
The valve opens automatically as soon as the floater reaches the highest point and closes again when the floater reaches the lowest point.
Setting the automatic mode:

If the drain screw is screwed in completely, the automatic drainage is blocked.

• Turn the drain screw to the right as far as it will go.

You may leave the screw one turn deep in the thread or remove it completely.
“Normally closed” configuration
The condensate drain is closed regardless of the operating pressure. The valve opens automatically as soon as the floater reaches the highest point and closes again when the floater reaches the lowest point.

4.1.3 Manual condensate drain
See g Fig. 3.
The condensate (b = max. fill level) can be drained manually.

1. Turn drain screw (a) to the left a few times until the condensate runs out.
2. Turn drain screw (a) all the way to the right (closed position).

Draining condensate via a tubing

1. Turn the drain screw (a) to the left and remove it.
2. Attach one end of the tubing to the reservoir and insert the other end into a receptacle.

4.2 Condensate separator
See → Fig. 6.
The condensate separator discharges condensate and oil from the compressed air network.
4.2.1 Connecting the condensate separator to the tubing system or maintenance unit
The ideal mounting position is at the lowest point of the compressed air network.

1. Connect the condensate separator. See → Fig. 8.
2. Screw the tube into the selected G 1/2 connection.

4.2.2 Semi-automatic condensate drain
The semi-automatic condensate drain closes at a pressure > 1.5 bar and opens at an operating pressure < 1.5 bar.
Setting the automatic mode:

If the drain screw is screwed in completely, the automatic drainage is blocked.

• Turn the locking wheel (b) all the way to the left.

You may leave the screw one turn deep in the thread or remove it completely.

4.2.3 Connecting the tubing
A tubing (a) can be plugged onto the oil drain at the bottom for controlled oil drainage.

1. Turn the locking wheel (b) to the left and remove it.
2. Attach one end of the tubing to the reservoir (a) and insert the other end into a receptacle.

Maintenance and repairs

5.1 Cleaning and servicing

• Close all openings with suitable safety devices so that no cleaning agent can enter the system.
• Never use solvents or aggressive detergents. Only clean the product using a slightly damp cloth. Only use water and, if necessary, a mild detergent.
• Do not use high-pressure cleaners for cleaning.
• Do not use compressed air for cleaning (blowing off) the maintenance unit or equipment.

Decommissioning, disassembly, exchange

CAUTION
The danger of injury in case of disassembly or replacement under pressure or voltage!
Disassembling or replacement when under pressure or electrical voltage may lead to injuries and damage to the product or system components.

1. Make sure that the relevant system part is not under pressure or voltage before disassembling the product or exchanging parts.
2. Protect the system against being restarted.

6.1 Filter
Exchanging the filter element

CAUTION
The system is operating under pressure!
Opening the system when it is under pressure can result in personal injury and cause damage to the maintenance unit/device.

• Please ensure that the system is not under pressure before you open the reservoir.

Filters become contaminated with use and must be changed annually. This, however, is only a recommendation, since the change intervals depend on the quality of the compressed air and the amount of air throughput.
Please use the material numbers listed below to order. The addresses of the AVENTICS GmbH international agencies can be found on the back.

Procedure
See → Fig. 4, → Fig. 5.

1. Release the ring (a) and pull it off downwards (b).
2. Release the protective guard (c), if present, and pull it off downwards.
3. Pull off the reservoir (d) and the seal (e) downwards.
4. Remove the filter seat (f, g).
5. Exchange the filter piece (h).
6. Slide the filter unit (filter seat and filter piece) back together.
7. Connect the filter unit to the filter and tighten it slightly by hand (i).
8. Remount the reservoir in the reverse order shown in g Fig. 4.

Disposal

Dispose of the product and fluid in accordance with the national regulations in your country.
