About this product

Distributors are components of air preparation units and are used to distribute compressed air. Pressure switches may be additionally mounted in flange and pipe connections. The following versions are available:

• DIS: Standard distributor
• DIC: Distributor with center infeed
• DIN: Distributor with non-return valve
  The following table lists assignment to the air preparation units:

Air preparation units| Version| Description| Circuit symbols See g Fig. 1
---|---|---|---
AS1| DIS| 2-fold| I
DIN| Non-return valve, 1-fold| IV
AS2| DIS| 3-fold| II
DIC| 3-fold| II
DIN| Non-return valve, 1-fold| IV
AS3| DIS| 4-fold| III
DIC| 4-fold| III
DIN| Non-return valve, 4-fold| V
AS5| DIS| 2-fold| I
| DIN| Non-return valve, 0-fold| VI

 Assembly, commissioning and operation

• Let the product acclimatize for several hours before commissioning, otherwise, water may condense in the housing.

CAUTION
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 increase during commissioning!
The system is exposed to sudden pressure on commissioning if no SSU filling unit is used! This may result in dangerous erratic cylinder motions.

• Please ensure when commissioning a system without a SSU filling unit that the cylinders are in their end position or that no danger can emit from those not in end position.

CAUTION
System is operating under pressure!
Incorrect installation may damage the air preparation unit/apparatus and cause serious injury.

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

5.1 Mounting fastening elements W01, W03, W04 and W05

•  Please heed figures g Fig. 7, g Fig. 6, g Fig. 8 and g Fig. 9.

5.2 Mounting the pressure sensor
**** On the AS5 series pressure sensors can only be flange-mounted.

5.2.1 Flange mounting
g Fig. 2

1. Remove the blanking screw (a).
2. Insert the molded seal (b) in the seal channel (c) of the air connection.
3. Place the pressure sensor (d) on the flange and screw it tight.

5.2.2 Pipe connection (AS1, AS2, AS3)
g Fig. 3

1. Remove the blanking screw (a).

2. Close the double nipple (f) with the seals (e1+e2) and screw the double nipple (f) into the distributor.
   Notice: The double nipple (f) must be ordered separately, seals (e1+e2) are included with the double nipple.

3. Screw the pressure sensor (g) onto the double nipple (f).

Service and repairs

6.1 Cleaning and servicing

• Close all openings with suitable safety devices so that no cleaning agent can enter into 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 air preparation unit or equipment.

Disassembly, exchange

CAUTION
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 without pressure or voltage before disassembling the product or exchanging parts.
2. Protect the system against being restarted.

Disposal

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

Conversion and extension

CAUTION
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 without pressure or voltage before disassembling the product or exchanging parts.

9.1 Change flow direction
g Fig. 5
On delivery the flow direction is from left (1, IN) to right (2, OUT). The following conversion on the product is necessary if the flow direction is to be changed:
9.1.1 Distributor conversion
On all components, the flow direction change is performed by rotating an installation by 180° around the vertical axis. The housing covers need to be changed for the purpose.

1. Release the housing cover at the front and back.
2. Re-attach the covers at the opposite sides with the cover bearing the AVENTICS logo facing to the front.

9.1.2 Component conversion on the DIC
**** Components with a flow direction from left to right need to be converted to change the flow direction on the DIC distributor with center infeed.

Troubleshooting

• Check tubing diameter
Leak on tubing| Check tubing and tubing connections

Technical data

Maximum permissible pressure, temperature range, and thread connection are indicated on the products.
