Note!
Due to the automatic draining of the frost-proof outer fit-
ting (3) after removal of water, water will continue to drain
out for a few seconds after closing the fitting (frost safety).
For this reason, the fitting only needs to be closed gently.
Note!
To ensure the correct ‘frost safety‘ function, hoses and
other attachements must be removed before the start of
the frost period!
Conduct functional testing of the
frost-proof outer fitting (3).
