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 straight to the test piece to prevent damage to the front
seal caused by possible sharp edges of the test piece.
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
– 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
Please observe the actuation direction of the clamping lever (Pos. 2). In the standard
arrangement, the clamping lever is actuated downwards and the ‘B1’ media inlet
faces upwards. It is possible to convert the clamping lever for upwards actuation to
suit the application. Please refer to
Chapter 9.4.4 Conversion of the clamping lever
(Pos. 2) on page 28
