Safety instructions for installation
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
depressurized condition.
Î
Avoid using excessively short media lines and narrow bending radii. Lateral forces
may cause leakages or damage to components and make it more difficult to attach
the WEH
®
Connector properly.
Î
Use arrestor cables, partitions, etc. for additional safety where being used for haz-
ardous applications or under hazardous conditions.
Î
USIT rings should be used to seal the ports.
Î
Before installation, check if the counterparts are designed to withstand the assembly
data (see
Chapter 7.2 Installation of media line and pilot pressure line
) 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.
