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 documentation. 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
®
Exchanger needs to be
protected from condensation with insulation 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.
NB!
If the ECONET
®
Exchanger Package is
disconnected from the ECONET
®
-unit, the
system might need an additional safety valve.
NB!
A purging valve must be fitted at the
highest point in the system.
