6 Assembly and installation

Before you start with the installation: Familiarize yourself with the basic specifica-
tions for assembly as early as possible in advance. See
g 6.2 Preparation.

6.1 Planning

In the following, you will read which basic requirements must be met so that you
can successfully and safely assemble the product.
Do not carry out the preparation and installation steps until you have successfully
completed the planning.

6.1.1 Basic requirements

The following specifications apply to the assembly of all products.
Installation-specific requirements
• Observe the set-up regulations in the country of use.
• Assembly only by qualified personnel. See
Ambient conditions
• Only use the product in non-aggressive industrial atmospheres (explosion
protection).
DANGER! Do not use the product in explosive areas. Only then can explosion
protection be guaranteed.
• Observe the heat radiation of the measuring medium.
• Measuring medium and ambient air must not condensate (see section
data).
g 13. Technical
• If the ambient air contains aggressive substances: Get in touch with our con-
tact address to determine whether use of the product is still possible. See
back cover.
• Let the product acclimatize for a few hours before installation. Otherwise wa-
ter may condense in the housing.
• Keep the installation location free from vibration.

6.1.2 Notes on safety

To eliminate risks during assembly, observe the notes on safety. See g 2. Safety.
Damage to the device or uncontrolled operation due to work on the system
when under voltage
When working under voltage, uncontrolled reactions and consequential in-
juries or damage are possible.
1. Before carrying out wiring work and before connecting/disconnecting elec-
trical connections, depressurize and de-energize the system.
2. Connect the electrical system completely.
3. Check wiring carefully.
4. Switch on supply voltage.

6.1.3 Installation conditions

General requirements
• Make sure that the product is installed in a manner that protects it from all
types of mechanical loads.
• Install the product in an area protected from UV radiation.
Product-specific requirements
• Mounting orientation. See g 13. Technical
• The measuring medium must be at least purity class 3:4:4 or better in accor-
dance with ISO 8573-1:2010.
• In compressed air networks, install the flow sensor downstream of the air
dryer.
If there is no air dryer: Install the flow sensor downstream of the condensate
separator and suitable filters.
• The correct reading only comes into effect from the minimum specified flow
rate, especially with horizontal mounting orientation. Due to the measuring
principle and self-heating, the reading may be incorrect below the minimum
specified flow.

6.1.4 Required accessories, materials and tools

Mounting material
and
If you use AVENTICS mounting material, see the online catalog for the relevant
data. Important information for assembly:
• Dimensions
• Tightening torques: Observe the values in the online catalog.
If no information is given on tightening torques or you use your own mounting
material, the generally recognized rules of technology apply to assembly.
Accessory parts
Depending on the chosen configuration and the application, additional compo-
nents are required to integrate the product into the system and the system's con-
trol.
• Approved accessories. See

6.2 Preparation

6.2.1 Notes

• Do not carry out any work on the system during preparation (accident preven-
tion).
• Protect the product with a separate fuse at the beginning of the supply circuit.
• In the case of extension cables with open ends, ensure that bare wire ends do
not touch. When the supply voltage is switched on, there is a risk of a short
circuit (accident prevention, material protection).
• Insulate the wires against each other accordingly (material protection).
• Wire cross-sections of the supply line supplied by the user must be in accor-
dance with DIN VDE 0100 (Part 430) and DIN VDE 0298 (Part 4) or DIN VDE
0891 (Part 1).
• Do not disconnect connecting cables and hoses in systems that are electrically
live or under pressure.
• Check whether the measurement range corresponds to the maximum flow
rate at the intended installation location (see section
Notes for variant AS-AF2
• Do not mount the flow sensor directly downstream of a regulator or filter reg-
ulator. Only use the specified sensor filter combination.
• After installing the product with a block assembly kit or mounting bracket: En-
sure tight screw connection.

6.2.2 Unpacking and checking the product

1. Check the material number to see if the product matches your order.
2. Check the product for transport and storage damage.
Do not install a damaged product. Return damaged products together with
the delivery documents. See back cover.
3. Prepare required accessories, materials and tools.

6.2.3 Implementing safety measures

Procedure
All work has to be prepared as follows:
1. Close off dangerous areas (accident prevention).
2. Make sure the system or system part is not under pressure or voltage (acci-
dent prevention, material protection).
3. Protect the system against being restarted (accident prevention).
4. Allow the product and adjacent system parts to cool down (accident preven-
tion).
5. Wear protective clothing (accident prevention).

6.3 Installation

Work steps at a glance
Installation consists of the following work steps:
• Step 1: Connect the pneumatic system (see section
