CAUTION!
If the plug brackets are not inserted
properly, the couplings can come loose
in their mounts which may result in high
levels of fluid escape and continuous
fluid escape.
Ɣ Before plugging in a plug bracket,
make sure that the plug bracket
engages in the groove in the coupling.
To do this, insert the coupling into the
mount until the groove becomes
visible through the plug bracket
mount.
Ɣ Insert the plug bracket up to the stop.
