Pump / Setting / Resistance Curves - elco TRIGON L Operating Manual

Commissioning
Control Measures
Standard boilers: Pump / Setting / Resistance curves
The initial commissioning shall be
performed by an authorized
specialist only
In general, the following control checks
must be performed prior to commissio-
ning:
Check power supply.
Check pressure in heating system.
Check pressure at gas connection.
Check gas supply for leaks.
Check proper assembly of exhaust
accessories.
Check condensate discharge for
leaks.

Minimum circulation amounts / Flow
monitoring
You must ensure that the system has
sufficient hydraulic flow upon heat
demand. The system is equipped with
a flow safety device which monitors the
through-flow. In order to maintain a
minimum flow, the installation of a
switch or a plate heat exchanger (both
available as accessories) is
recommended, or the connection of
the TRIGON L to an open manifold.

Ensure prior to commissioning
Sufficient dimensions of the expansi-
on container must be ascertained.
Comply with notes on water quality,
fill with softened water if necessary.
Commissioning of system and venting
shall take place immediately after the
filling process in order to eliminate
standing air pockets as a center of
corrosion.
Commissioning at low system tempe-
ratures and maximum through-flow of
the heating system avoid calcium
deposits inside the boiler.
During inspection work, the complete
exchange of the system water should
be avoided. This can be accomplis-
hed through partial shutoffs or
through reuse of retained and filtered
system water.
