Î
Apply pressure to the WEH
®
Connector only once it has been connected to a test
piece.
Î
Do not use excessive force when actuating.
Î
Follow the steps in
exactly
the right order when connecting and disconnecting the
WEH
®
Connector.
Î
Attach and detach the WEH
®
Connector only when it is not under pressure.
Î
Connect the WEH
®
Connector only to test pieces in full working order.
Î
Align the WEH
®
Connector correctly with the test piece to prevent damage to the
front seal caused by any sharp edges that the test piece may have.
Î
Do not actuate the WEH
®
Connector without a test piece. The seals can be damaged
without the test piece connected.
Î
Once the connection has been made, always test the connection by tugging a little
on the WEH
®
Connector to make sure that is fully engaged and that the clamping
jaws are gripping correctly before introducing the pressurized test medium.
Î
The clamping jaws of the WEH
®
Connector are designed to grip the test piece. Keep
fingers and other objects away from the clamping jaws when actuating the connec-
tor.
Caution:
Possible consequences of failing to observe this instruction may include:
– Risk of fingers being crushed while connecting and disconnecting
– Risk of personal injury and damage to property by parts
that may become detached under high pressure
– Risk of personal injury by media escaping
at high pressure
– Risk to human safety by hoses not being secured
Î
The WEH
®
Connector is not fitted with an integrated shut-off valve and thus will not
prevent loss of test medium when disconnecting. Therefore it is important to discon-
nect the connector only under absolutely safe conditions.
Î
Note that the clamping lever (Pos. 2) is equipped with a short lever as standard. This
allows convenient connection to components that are difficult to access. Depending
on the application, the WEH
®
Connector can be equipped with a lever extension for
ease of use and when space is not limited. Please refer to
the lever extension (Pos. 5) for body size 1 to 3 on page 33
