Function
The Caleffi SEP4™ combination separator is a device that
incorporates four critical functions for hot or chilled water sys-
tems. 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 perfor-
mance 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 sys-
tem, 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.

CAUTION: If the SEP4™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 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 hydraulic separator, take the necessary precautions
to ensure that such temperatures do not endanger people.

trained in the proper application, installation, and maintenance of
systems in accordance with all applicable codes and ordinances.

Insulation
The SEP4™ comes standard with a preformed insulation shell. Theinsulation is made of a shell in
closed-cell expanded PE-X foam. This insulation ensures not only perfect heat insulation but also the
tightness required to prevent atmospheric water vapors from entering the unit. Forthese reasons,
this type of insulation can also be used in cooling water circuits, as it prevents the formation of con-
densate on the surface of theseparatorbody.
Procedure for installation and insulation assembly
1. Remove the two black head covers at the ends.
2. Open the two side sections.
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 surfaces A and B. Wait
for solvent to evaporate (approx. 10 minutes). Note that once the
sealant dries it may be difficult to remove the insulation shell in the
future without destroying portions of the insulation.
5. Reassemble the two side sections.
6. Finish the assembly with adhesive tape (not supplied).
7. Complete by assembling back in place the two black head covers.

Hydraulic characteristics
The SEP4™ should be sized according to the maximum flow rate at the inlet. The selected value is
the primary circuit flow rate, or secondary circuit flow rate, whichever is largest.

Installation
The SEP4™ should be installed only by qualified personnel in accordance with current local codes
and legislation. The SEP4™ is installed between the primary and secondary circuits, always in a
vertical position.
CAUTION: Corrosion or leakage can cause damage or injury. Periodically
inspect for signs of corrosion or leakage. If corrosion or leakage is noted,
the vent must be replaced. Failure to follow these instructions could result in
property damage and/or personal injury.
Service instructions
There is no service required for the SEP4™ combination air, hydraulic, dirt and magnetic separator.
