DIRTMAG® dirt separator with magnet, adjustable for
vertical or horizontal pipe
© Copyright 2018 Caleffi
Installation, commissioning and servicing instructions
The NA5453 series is available with conventional union NPT and union sweat union connections
and the Presscon™ press copper tail-piece with union nut that makes installation and maintenance
fast, easy and efficient. Special slots in the EPDM O-ring allows fluid to leak during system testing
if unpressed and provide a perfect leak proof seal when completely pressed. Also, models are
available with isolation inlet and outlet shutoff valves, which can be used as a dosing point to inject
chemical additives into the hydronic circuit.
These items are designed for use in closed hydronic systems. Do not use in plumbing applications. These
items do not meet the low-lead plumbing standards of U.S. and Canada.

Function
In heating and chilled water 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 heat
exchangers, heating elements and pipes, resulting in
lower thermal efficiency within the system.
The dirt separator separates off these dirt particles,
circulating within the closed circuit system. These
particles are collected in a large chamber, requiring
infrequent cleaning, which requires simply removing
the magnet ring and opening the large drain valve
while the system is running. This device is capable of
efficiently removing particles to a very small size, with
very low pressure head loss.
The DIRTMAG® magnetic dirt separator removes
both ferrous and non-ferrous impurities continuously,
featuring a powerful removable external magnet
around the body that removes up to 100% of the
ferrous impurities, including magnetite, that can
form in a hydronic system. The DIRTMAG
times the removal performance of a standard dirt
separator. The body of the NA5453 series separator
is made of glass reinforced nylon specifically
designed for use in heating and cooling systems. It
also is especially versatile as it can be installed on
either horizontal or vertical piping with the rotating
brass base mount.

SAFETY INSTRUCTION
This safety alert symbol will be used in this manual to draw attention to safety related
instructions. When used, the safety alert symbol means.
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED! FAILURE TO
FOLLOW THESE INSTRUCTIONS MAY RESULT IN A SAFETY HAZARD.
WARNING: This product can expose you to chemicals including lead, which is
known to the State of California to cause cancer and birth defects or other
reproductive harm. For more information go to www.P65Warnings.ca.gov.
CAUTION: All work must be performed by qualified personnel trained in the
proper application, installation, and maintenance of systems in accordance
with all applicable codes and ordinances.
CAUTION: If the DIRTMAG® separator is not installed, commissioned
and maintained properly, according to the instructions contained in this
manual, it may not operate correctly and may endanger the user.
CAUTION: Make sure that all the connecting pipework is water tight.
CAUTION: When making the water connections, make sure that the
pipework connecting the DIRTMAG® 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.
CAUTION: Water temperatures higher than 100°F (38°C) can be dangerous.
During the installation, commissioning and maintenance of the DIRTMAG®
separator, take the necessary precautions to ensure that such temperatures
do not endanger people.

AVERTISSEMENT:
le plomb, qui est connu dans l’État de Californie pour causer le cancer, dommages à
la naissance ou autre. Pour plus d’informations rendez-vous www.P65Warnings.
ATTENTION: Tous les travaux doivent être effectués par du personnel
qualifié formé à la bonne application, installation et maintenance des systèmes
conformément aux codes et règlements locaux.
ATTENTION: Si le DIRTMAG® n'est pas installé, mis en service et
entretenu correctement, selon les instructions contenues dans ce manuel, il
peut ne pas fonctionner correctement et peut mettre en danger l'utilisateur.
ATTENTION: S'assurer que tous les raccordements sont étanches.
ATTENTION: Lorsque vous effectuez les raccordements d'eau, assurez-
vous que la tuyauterie reliant le DIRTMAG® n'est pas mécaniquement des
overstressed. Au fil du temps, ceci pourrait causer des ruptures, avec
pour consequence des pertes en eau qui, à leur tour, peuvent causer des
dommages à la propriété et/ou les gens.
ATTENTION: Les températures de l'eau supérieure à 100°F (38°C) peut
être dangereux. Au cours de l'installation, mise en service et l'entretien de
le réducteur de pression, le DIRTMAG®, prendre les precautions nécessaires
afin de s'assurer que de tells températures ne compromettent pas les gens.

Maintenance
Eliminate air
collected in the
top of the body
by loosening the
top plug screw.
Draining off dirt and ferrous impurities
Remove the magnetic ring (1) and drain the
collected dirt and ferrous impurities. This can
be done while the system is running, using
the key provided (2).

Dosing
This multifunction device can also be used as a
dosing point to inject chemical additives into the
circuit. Codes NA545355 and NA545356 offer
integral isolation check valves making for a more
convenient dosing vessal, providing an easy
access point for routine system water treatment
in hydronic systems.
To perform maintenance
after isolating the separator,
simply unscrew the top cover
using the provided key
and remove the attached
internal element inside the
collection chamber.
WARNING: The symbol shown on the
removable ring indicates the presence of
magnets that generate a strong magnetic
field. This could cause damages to electronic
devices kept in its proximity.
1. Remove the magnetic ring containing the
two magnets, that during operation attracted
the magnetites.
2. Flush out the ferrous and nonferrous debris
by turning the handle to open the drain valve.
3. When finished, replace the magnetic ring
and close the drain valve.
