HEATING OPTIONS
Hot water coils
The hot water coil is
fi
tted with a three way proportional valve . Two spanners must be used to
tighten the connections. One spanner must maintain the valve body when connecting the pipe-
work to the main. Failure to do so may damage the pipes joints and invalidates the warranty.
Filling up and starting the system
• Adjust the control for Heating by reducing the simulated ambient temperature down to 10°C
• Check that the red indicators located under the valve actuator are moving correctly with the
signal.(Arrow on the picture)
• Fill the hydraulic system and bleed the coil using the air vents. Check incoming hot water
fl
ow rate.
• Check the various connections for possible leaks
Freeze protection
Check the hydraulic system contains glycol for protection against freezing. Glycol is the only effective protection against freezing. The
antifreeze must protect the unit against freezing under winter conditions.
Drain the installation
You must ensure that the manual or automatic air vents have been installed on all high points in the system. In order to drain the
system, check that all the drain valves have been installed on all low points of the system.
Heating hot water coils frozen due to low ambient conditions are not covered by the warranty.
Electrolytic corrosion
Attention is drawn to the corrosion problems resulting from electrolytic reaction created by unbalanced earth connections. Any coil
damaged by electrolytic corrosion is not covered by the warranty.
Warning: glycol based fl uids may produce corrosive agents when mixed with air.
