Top connection
The connection on the top of the dirt separator can be
used to install an automatic air vent, code 502040
MINICAL for the threaded version (A), code 501500
MAXCAL for the flanged version (B).
Maintenance
To carry out maintenance operation (in threaded
models for horizontal pipes) (C), simply use a 26 mm
hexagonal wrench (1) to unscrew the dirt collection
chamber to which the internal element is fixed, in order
to extract it for cleaning purposes. For vertical pipe
models (D), only the dirt collection chamber may be
unscrewed for cleaning procedures, without the whole
internal element being removed.

Insulation
Flanged DIRTCAL
®
and DIRTMAG
®
(from DN 50 to DN 150) devices
are supplied complete with hot
pre-formed shell insulation (G - H).
This system ensures not only
perfect thermal insulation, but
also the tightness required to
prevent water vapour entering the
device from the ambient.
For this reason, this type of
insulation may also be used in
chilled
water
circuits
as
it
prevents
condensation
from
forming on the surface of the
valve body.

Draining off with the system
running
The dirt separator collection
chamber is equipped with a ball
shut-off cock with special lever in
the threaded version (E), and with
a ball shut-off valve with butterfly
handle in the flanged version (F).
These valves can be used to
drain off the impurities which
have collected at the bottom of
the dirt separator, even while the
system is in operation. In the
version
with
magnet,
the
procedures described must be
carried out after the magnet has
been removed (G and H). In the
flanged version, the magnet can
be removed after unscrewing the
knob (G). To make this operation
easier, the magnet is divided into
several pieces.

The maximum recommended speed of
the medium inside the pipe is 1,2 m/s.
The following table shows the maximum
flow rates in order to meet this
requirement.
