The WEH
®
Connector is not fitted with an integrated shut-off valve and thus will not
prevent loss of medium in case of improper connection or after disconnecting. Apply
pressure to the connector only once it has been properly connected. It is important
to disconnect the connector only under absolutely safe conditions. In particular, the
connector must be fully depressurized during the disconnection process.

Connection
Please note:
When using the weight and height compensation system, place the bottle
on the corresponding system. Press the bottle down until the cylinder valve and the
filling connection are opposite each other.
Î
Press and hold down the locking device (Pos. 8) and then
fold the actuation unit (Pos. 1) upwards (
Figure 4
). The
clamping jaws will close together.
Î
Insert the connector loosely and straight into the cylinder
valve until a noticeable seal contact has been established.
Doing so will prevent any damage to the front seal caused
by any sharp edges on the cylinder valve and ensure a
correct connection.
Attention:
Make sure that the connector is pressed onto
the cylinder valve until a noticeable seal contact has been
established.
Î
Fold the actuation unit (Pos. 1) downwards (
Figure 5)
.
It must be possible to lower the bail/lever easily and
without any force. The actuation unit (Pos.1) is correctly
positioned when the locking device (Pos.8) engages with
an audible click. The position of the locking device
(Pos. 8) changes from horizontal to a diagonally upward
pointing position. The thread segments clamp tight when
connected to the thread of the cylinder valve. In its end
position, the actuation unit (Pos. 1) must be below the
horizontal of the connector (
Figure 6
).
Attention:
If the clamping jaws do not grip correctly at
the cylinder valve or if the actuation unit is not below the
horizontal, then the connector is not properly connected.
The connector may spring out of place and medium may
escape.
