Construction details
The DISCALDIRTMAG
®
air and dirt separator is designed to be
maintained and cleaned without removing it from systempiping.
The automatic air vent, located at the top of the device, has a long chamber for
float movement (2). This prevents any impurities in the water from reaching
the seal seat. The corrosion resistant stainless steel pinned linkage and
PP float can be accessed by removing the upper cover (1). The stainless
steel float guide pin (4) prevents the float from jamming against the inside
housing, sticking due to accumulating residue in the flowing fluids, in non-
vertical installations or from boiler or chiller residue buildup.
Unscrew the top part of the casing (3) to clean the entire air ventingsystem.
The air venting system in the brass DISCALDIRTMAG
®
and steel
DISCALDIRTMAG
®
air and dirt separators features a pinned float.
Steel DISCALDIRTMAG
®
air and dirt separators with flanged and
threaded connections have an integral side drain port with shutoff valve,
code 538402 FD (5), which has two functions:
1. Air removal while filling the system during system commissioning.
2. Debris removal that float within the air separator.
The drain valve (code NA39753 - 1 inch or code NA59600 - 2 inch) installed
on the drain pipe at the base of the steel DISCALDIRTMAG
®
air and dirt
separator (8) can be used to remove any debris that has settled at the
bottom of the separator, even while the system is in operation. To inspect
the internal element of brass DISCALDIRTMAG
®
air and dirt separators,
unscrew the large dirt separation chamber (6) with a 26 mm hexagon
wrench. The internal element can be removed for cleaning. Additionally, the
brass air and dirt separators have a lever operated shut-off drain valve code
538402 FD, and ¾" garden hose attachment with plug (7), to drain accu-
mulated debris as needed.
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 even
with the system in operation.
For the brass DISCALDIRTMAG
®
, captured ferrous impurities are easily
flushed by unclamping the magnetic collar and purging.
To purge the ferrous impurities
in the steel DISCALDIRTMAG
®
,
the flexible magnetic stack
is removed from the brass
dry-well and, with the system
still running, the drain valve is
opened. Aided by the system
pressure, the dirt and ferrous
impurities, including magnetite,
flushes out quickly and
effectively.
