Installation, commissioning and servicing instructions
Function
In heating and air conditioning control systems, the
circulation of water containing impurities may result in
rapid wear and damage to components such as pumps
and control valves. It also causes blockages in the heat
exchangers, heating elements and pipes, resulting in
a lower thermal efficiency within the system. The dirt
separator removes these dirt particles from the fluid,
collecting them in a large collection chamber, from
which they can be drained even while the system is in
operation. This device is capable of efficiently removing
even the smallest particles, with extremely limited head
loss.
The DIRTMAG® PRO dirt separator with dual magnets
extends the Caleffi dirt separator family by adding a
powerful neodymium magnetic stack inside a drywell
inserted into the top of the body within the flow stream.
Additional magnetic flux increases the speed of
magnetite (ferrous impurities) removal from the hydronic
fluid for maximum protection.
Insulation shells are available separately.
This item is designed for use in closed hydronic systems. Do not use this item in plumbing applications. It does
not meet the low-lead plumbing standards of U.S. and Canada.

CAUTION: When making the water connections, make sure that the dirt separator connecting
pipework is not mechanically over-stressed. Over time this could cause breakages, with consequent
water losses which, in turn, could cause harm to property and/or people.

pourrait causer des ruptures, avec pour conséquence des pertes en eau qui, à leur tour, peuvent causer
des dommages à la propriété et/ou les gens.
CAUTION: Water temperatures higher than 100°F (38°C) can be dangerous. During the installation,
commissioning and maintenance of the dirt separator, take the necessary precautions to ensure that
such temperatures do not endanger people.

BI-DIRECTIONAL
The dirt separator must always be installed in a vertical position, preferably on the return circuit
upstream of the boiler (or chiller). This enables it to intercept dirt particles already present in the
circuit, particularly when it is first started, before they reach the boiler (or chiller).
Flow direction for the DIRTMAG PRO dirt separators is bi-directional; flow in either direction is
permitted.

Draining off dirt and ferrous impurities
The dirt separator collection chamber has a drain
valve. Using the handle provided it is possible to drain
off the accumulated dirt particles without removing
the element from the fluid.
For the DIRTMAG PRO, captured impurities are
easily flushed by unclamping the magnetic collar,
pulling out the fexible magnet stack from the topmounted brass dry-well and opening the drain valve.
Allow for a minimum 4¾ inch space above the
separator to completely remove the magnet stack.
Aided by the system pressure, the dirt and ferrous
impurities, including magnetitie, flushes out quickly
and effectively.
Procedure for removing insulation and draining dirt particles in
the DIRTMAG PRO 5463AM series
WARNING: The symbol shown on the removable ring (A)
indicates the presence of magnets that generate a strong
magnetic field. This could cause damage to electronic devices
kept in its proximity.
1. Turn off circulator
2. Remove the ring (A) containing the two magnets and
pull out the flexible magnetic stack from the top drywell.
3. Open the ball shut-off valve (B) to drain the accumulated
dirt and ferrous impurity particles.

Maintenance
To perform annual inspection and maintenance, if
needed, simply use a 26 mm hexagon wrench (1) to
unscrew the dirt collection chamber, of the DIRTMAG
PRO, to which the inner mesh element is connected for
removal and cleaning.
Bottom connection
The DIRTMAG PRO comes complete with a
drain valve installed on the bottom port, Caleffi
code 538402 FD.

Safety
The dirt separator must be installed by a licensed plumber in accordance with national regulations and/
or relevant local requirements.
Make sure that all connecting joints are water tight.
When making pipe connections take care not to damage the thread in the body of the valve by over
tightening. Take care not to apply too much force to the body of the valve when making pipe connections.
Water temperatures greater than 120°F may cause serious burns. When installing, using and
maintaining dirt separators take appropriate measure to ensure that these temperatures do not cause
harm to persons.
