Recipient for storage of probe
The collar holding the recipient for
the storage of the probe has to be
fixed on wall, close to the place
where the probe is installed. The
probe should be kept in that
recipient when the unit is not in
operation (out of season). The
Liquid inside this recipient is
special for storage of the probe
(KCl) and should be kept in that
recipient.
The plug of the recipient of the
probe can be used to close the
filtration circuit when the probe is
removed (out of season).
