Î
Check the information provided in these operating instructions and the label on the
WEH
®
Product. The information must conform to your application.
Î
Only connect the WEH
®
Product to faultless connections.
Î
Check the WEH
®
Product for transport damages, contamination and other damage. If
you should detect anything wrong with the WEH
®
Product, it may no longer be used.
Replace the WEH
®
Product or send it to WEH for maintenance.
Î
Remove transport securing devices (such as protection caps) before installing the
WEH
®
Product. Transport securing devices serve the purpose of protecting the
product and connection ports during transport and storage. The transport securing
devices are not, for example, designed to withstand pressure or to be used as plugs.
Î
Ensure that the system is depressurized. Installation must only be effected in de-
pressurized condition.
Î
Install the WEH
®
Product carefully without exerting any force.
The product must not be exposed to any additional mechanical stress. Additional
mechanical stress, e.g. lateral forces caused by connected pipes, may lead to leak-
ages and may cause the product to burst.
Î
Relevant technical standards must be observed during installation.
Î
The WEH
®
Product is mounted between two pipe or hose ends of the media line.
Installation of the product may be carried out with the media line in any position, hori-
zontal, vertical, diagonal etc.
Attention:
Observe the direction of the flow – the flow direction is marked on the
housing.
Note:
Please note the information about the installation position on the quotation. If
the cracking pressure is particularly low, an incorrect installation position may nega-
tively impact the product's functionality.
Î
Before installation, check if the counterparts are designed to withstand the assembly
data (see
Chapter 7.2 Installing the check valve
) that WEH determined for this
WEH
®
Product.
Note:
The indicated assembly data (tightening torques, assembly turns etc.) are values
that apply only to the components delivered by WEH.
