Shut/off valve and check valve
Deaerator
The group is equipped with shut-off valves with thermometer and built-in check valve 4 and 8 (Table1-page 3). The
valves intercept the delivery and return flow to let fill, wash and discharge the system. They also enable a quick and
easy replacement of the pump without emptying the system.
The shut-off valves are also equipped with check valves which ensure the proper flow of the heat-transfer fluid inside
the solar circuit preventing undesired refluxing when the pump is not working
1. To fully close the shut-off valves turn the regulatig handles clockwise until they stop (Pict.5).
2. To allow the fluid to pass through the valves in both directions and open the check valve, turn the regulating
handles to 45° (Pict.6).
3. During the normal operating cycle instead, the valves must be in the position shown in Pict.7 by turning the
regulating handles counter-clockwise until they stop.
The solar modules S001, S002, and S004 is equipped with a deaerator 9 (Table1-
page 3).
During the normal functioning of the solar circuit, the air present in the heat-
transfer fluid is separated and collected in the upper part of the deaerator.
During the start-up, the air collected in the deaerator has to be periodically
discharged by the manual air vent located in the upper part of the deaerator
by turning its spindle counter-clockwise with a screwdriver. After discharging
all the air in the deaerator, close the vent by turning its spindle clockwise until
it stops.
Once the star-up is completed, for a first period,
this operation must be repeated
every month.
Then it will be sufficient to repeat this operation
every 6 months to mantain the
solar system efficient.

RISK OF BURNS!
When bleeding the system, depending on the pressure and temperature of the heat-transfer fluid in the system,
opening the air vent may cause a high-speed jet of high-temperature liquid or water vapour, dangerous for the operator.
To prevent any accidents, please follow these instructions:
- Wear appropriate protective equipment to protect hands and face.
- Carefully turn the air vent
- Keep your face away from the deaerator to avoid accidental burns.
- Protect all components and electrical connections from water.
