Below are recommendations on design of the hydraulic connection to the coils:

During the design phase, envisage the installation of the following components on the inlet water line:
AV - Anti-vibration: to isolate the vibrations that can be transmitted from the system.
-
-
M - Pressure gauge (with stopcock): indicates the water pressure in the inlet line.
T - Thermometer: indicates the water temperature in the inlet line.
-
-
SA - Air vent: to eliminate air in the inlet line.
-
SC - Drain valve: to drain water out of the system. To be used also for connecting an external pump for chemical
washing.
MF - Mains filter: (with a system of RU valves for cleaning the filter): for trapping impurities in the system.
-
Assemble the following components on the water outlet line:
-
RUa - Shut-off valves: for shutting off the supply of water to the machine during maintenance.
AV - Anti-vibration: to isolate the vibrations that can be transmitted from the system.
-
-
M - Pressure gauge (with stopcock): indicates the water pressure in the inlet line.
-
T - Thermometer: indicates the water temperature in the outlet line.
-
SA - Air vent: to eliminate air in the outlet line.
SC - Drain valve: to drain water out of the system. To be used also for connecting an external pump for chemical
-
washing.
Install an expansion vessel with a safety valve in the hydraulic circuit. The hydraulic circuit must be sized according to the applicable
.
laws in force
CAUTION:
Maximum operating pressure 10 BAR, including the hydrostatic head – PN10.
The connection pipes must be suitably supported so that they do not weigh down on the machine.
Avoid rigid connections between the machine and the pipes, and install vibration dampers.
For temperatures, minimum and maximum water flow rates and the volumes of water in the heat exchanger hydraulic circuit
refer to the technical bulletin.
Any heating elements installed to prevent the pipes from freezing must be kept away from devices, sensors and materials that
the heating elements could damage or cause to malfunction (for example, temperature sensors, plastic components and power
cables).
The carrier fluid in the water circuits must be prevented from flowing in the reverse direction as this can damage the pumps or
cause by-passes, affecting the flow and temperature of the system.
