Function
The Caleffi SEP4™ combination separator is a device that
incorporates four critical functions for hot or chilled water systems.
It combines high performance air and dirt (magnetic and non-
magnetic) removal into the hydraulic separation function which makes
the primary and secondary circuits connected to it hydraulically
independent. The SEP4™ features an internal coalescing element
that continuously and automatically eliminates air micro-bubbles with
the simultaneous removal of dirt particles as tiny as 5 microns. The
air discharge capacity is very high, with the capability of automatically
removing all the air present in the system down to the micro-bubble
level. The 4-in-1 high performance functionality of the SEP4™ saves
system installation and maintenance costs as there is no need to
include separate air and dirt separators. In addition to removing solid
impurities in the system without isolating the separator or shutting
down the system, the added powerful removable external magnet
belt (union) or probe(s) (flanged) in the lower body removes up to
100% of the ferrous impurities, including magnetite, that can form in a hydronic system. The SEP4™
has 2½ times the ferrous impurities removal performance of standard air and dirt separators.
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.

Agency Approval
Series NA549_M is designed and built in accordance with Section VIII, Division

CAUTION: Make sure that all the connecting pipework is water tight.
CAUTION: When making the water connections, make sure that the hydronic
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.
CAUTION: Water temperatures higher than 100°F (38°C) can be dangerous.
During the installation, commissioning and maintenance of the hydronic
separator, take the necessary precautions to ensure that such temperatures
do not endanger people.

Installation
The installation of SEP4™ should only be done by qualified personnel in
accordance with current legislation. The SEP4™ is installed between the
primary and secondary circuits, always in a vertical position.
Hydraulic
characteristics
The SEP4™ should be sized according to the maximum flow rate of either
the primary circuit, or secondary circuit, whichever is largest.

Service Instructions
There is no service required for the SEP4™ combination hydraulic, air, dirt, and magnetic separator.
CAUTION:
Corrosion or leakage can cause damage or injury.
Periodically inspect for signs of corrosion or leakage. If corrosion or
leakage is note, the vent must be replaced. Failure to follow these
instructions could result in property damage and/or personal injury.
Procedure for installation and insulation assembly
(only for
2” to 4” sizes)
1. Remove the two black head covers at the ends.
2. Open the two side sections and the lower cap.
3. Install the separator in the system.
4. For cooling applications, consider using a silicon caulk
or sealant by spreading a thin layer of sealant over
the shell mating surfaces.
5. Reassemble the two side sections, fitting the lower cap
into one of the two sections and then connecting the other.
6. Complete with the two black head covers.
7. Install the automatic air vent and the drain valve.
Isolating the air vent valve
The air vent (A), replacement part number 501502A, is isolated
manually, using a shut-off ball valve (B), replacement part number
NA39589.
Dirt removing element
The SEP4™ dirt removing element separates
and collects any impurities present in
thesystem.
Ferrous impurities removal element
The SEP4™ ferrous impurities removing ele-
ment is a flexible magnetic stack inside a
brass dry-well probe (three for the 8 to 14 inch
size SEP4™) just below the flow stream in the
lower body. The probe(s) attracts and holds
the magnetite in the lower body and is flushed
by unscrewing the magnetic probe(s) and slowly pulling it out of
the dry-well and purging through the open drain valve- aided by the
system pressure.
