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
Once the connection has been made, gently test the connection by tugging a little
on the test piece to make sure that it 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
The WEH
®
Connector is actuated by compressed air. This acts on a piston which col-
lapses the clamping jaws (Pos. 3), allowing them to be connected to the test piece.
Î
Make sure that the test pressure is not built up until the required pilot pressure for
sealing has been removed.
