Installation, commissioning and servicing instructions

NA5453 Series

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 heat exchangers, heating elements
and pipes, resulting in lower thermal efficiency
within the system.

The dirt separator separates off these dirt particles
which are mainly made up of particles of sand and
rust, circulating within the closed circuit system.
These particles are collected in a large chamber,
requiring infrequent cleaning, which requires simply
removing the magnet collar 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 magnetic and non-magnetic particles
continuously, featuring a powerful removable
external magnet around the body. 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.

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.
