ECONET®Exchanger Package, scope of delivery
System overview:
The Exchanger Package illustrated in the figure is deliv-
ered separately from the AHU and the ECONET®pump
unit. Basically, the Exchanger Package consist of one or
two plate heat exchangers for connection to an external
heating and/or cooling system.
The pipework within the ECONET®Exchanger Package is
protected against rusting and insulated with Armaflex.
The ECONET®Exchanger Package comes with a stand
for mounting on a flat floor.

ECONET®Exchanger Package:
The ECONET®Exchanger Package contsists of one or two
plate heat exchangers for supplementary heating and/or
cooling. The exchangers are made of AISI 316 stainless
steel, brazed with pure copper. The typical pressure rating
is 31 bar (450 psi), and the typical temperature rating is
225°C (437°F).
The tubes are made of high-pressure steel, painted with
anti-corrosion paint. These are then insulated with Armaflex.
The heat exchanger package, the ECONET®pump unit
and the external pipework must not exceed a total pressure
drop of 40 kPa for maximum liquid flow. If the pressure
drop is higher (a long distance between the components),
it should be taken into account when dimensioning the
system.
The pipe connections are male pipe threads from DN25
to DN50. The connections on the primary side against the
plate exchangers are female pipe threads from DN25 to
DN50. For dimensions DN65 and DN80, all connections
are assembled flanges.
The opening pressure for the delivered safety valve is
4.0 bar.
All sizes of ECONET®Exchanger Package come with a
specially designed stand that is made for floor standing.
The unit is delivered on a separate pallet.
Packaging
Suitable packaging protects the ECONET®Exchange
Package during transport. This is fully environmentally
compatible, and should be taken for central disposal as a
secondary raw material.

ECONET®manual 8170. This instruction only covers
what is valid for the ECONET®Exchanger Package.
Unpacking
Inspection of delivered equipment
– Check for signs of transit damage.
– Check that the product codes on the rating labels
conform to your requirements.
– Check the delivered components against the bill of
material.
– The code for the ECONET®Exchanger Package can be
found on one of the heat exchangers.
Installation instruction:
The following shall be carried out on site by the
plumbing/automation and electrical contractors.
– Installation of necessary components for connecting
an external energy source, as set out in the documen-
tation.
– Filling and air purging of system.
– Equipment and controls for supplementary heating
and cooling (SV30, SV50).
Pipe installation:
– Installation of pipes between the ECONET®
Exchanger Package and the ECONET®pump unit.
– Installation of the piping from the external energy
source.
– Filling and air purging of the ECONET®circuit and
the external water system.

ECONET®Exchanger Package, assembly and installation
Pipe installation
Connection to the pipe system should be carried out by
the plumbing contractor.
Installation normally includes:
– Installation of necessary components for connecting
an external energy source, as set out in the documen-
tation. The necessary components vary depending on
the design of the object. Examples of external
components are:
Automatic air purging valve combined with a
manual air purging valve
Air purging valves for micro bubbles
Filter
Charging equipment
Water trap
Anti-freeze liquid
– Installation of the ECONET®Exchanger Package to
the ECONET®pump unit.
– Mounting of control valves for supplementary
heating and/or cooling.
The installation of the ECONET®Exchanger Package
must not impose any loads on any pipes within the
ECONET®pump unit.
The ECONET®Exchanger Package is build to stand on a
flat floor. The ECONET®Exchanger Package comes with
a stand suitable for its size.
The connection of the supplementary heating and/or
cooling must be according to the plates mounted on the
ECONET®Exchanger Package and the ECONET®pump
unit.
These plates indicate:
– Which of the plate heat exchangers are intended for
heating and cooling.
– Inlet and outlet of the exchangers for primary heating
and cooling.
– Pipes for connection to the ECONET®pump unit.
With the pipes installed correctly, the ECONET®Exchang-
er needs to be protected from condensation with insula-
tion on the pipes to/from the primary systems.
The shut-off valves on ECONET®Exchanger Package
must be open when the system is running as normal.
IMPORTANT!
– Hold the pipe connections steady with a pipe wrench
when tightening external pipes.
– Use flax (hemp) and paste for sealing the connections.
– Use sealings suited for anti-freeze liquids, such as
etylen glycol mixtures.
NOTE!
In the ECONET
®
Exchanger Package is disconnected from
the ECONET
®
unit, the Econet system might need an addi-
tional safety valve.
NOTE!
A purging valve must be fitted at the highest point
in the system.
