It is possible to adjust the drain in the most appropriate direction rotating the motorised ball drain valve and its fitting after loosening the cap. Take
care not to bend-stress the valve. This operation must be carried out before commissioning, with a completely empty and pressure-free device.
The device drains the liquid collected that can be at high temperatures (> 50°C), depending on the characteristics of the system in which
it is installed: use appropriate precautions to comply with local regulations in force and concerning the water drain.
To prevent contamination of the drinking water network and to avoid backflow phenomena, install a hydraulic backflow preventer and a
suitable strainer upstream of the strainer cleaning solenoid valve.
Limit as much as possible the length of the domestic pipes used for cleaning: use water hammer arrester or other devices to suppress
instantaneous overpressure that may occur during operation.
The domestic water inlet line for strainer washing may be subject to thermal overpressure: install suitable safety relief valves or expansion
vessels.
The domestic hot water inlet line may be subject to freezing risk. Provide suitable insulation or systems to avoid ice formation.
To allow an easier installation it is possible to invert the position of the inlet valve V1 with the automatic air vent having the same 2 1/2” thread. This
operation must be carried out during installation, with a pressure-free and completely empty strainer.
