The siphon supplied with the RHE unit is designed for a pressure available on the supply system of 300
Pa maximum. Pass the threaded pipe through the condensates dip tray and the bottom of the RHE unit
and then tighten the nut below. Fit the siphon in the threaded pipe.
The minimum drain slope must be 5 / 1000.
To size a siphon: H min (mm) = 4 + pressure drop of the air injection network (da Pa).
Thermostat change over (reversible water coil DFR version HD only)
A thermostat change over (THCO PROBE) is installed on the hydraulic network and connected to the
unit’s electrical box. It allows reversing the mixing valve control in installations with only one coil according
to the temperature of fluid detected in the valve inlet.
