COMPONENTS AND FUNCTIONS
1. Solar pump.
2. Circuit draining and filling valve.
3. Filling taps.
4. Air draining chamber.
This element stores the fluid of the primary
circuit when the system is stationary and the
air from the collector field when the pump is
running.
5. Pressure gauge.
6. Safety valve set to 3bar.
7. Flow meter and level indication.
The flow may be adjusted on this element
which also indicates the fluid level we have on
the primary circuit.
8. Expanded Polypropylene insulating housing
(EPP).
9. Solar controller (in systems with control
included).

INSTALLATION
•
Positioning and fixing to the wall.
The Drain-Unit can be installed at any height on the solar collectors within the ranges established for
the different models. The less height there is between the collectors and the Drain-Unit, the less power
required from the pumps and, therefore, the greater the efficiency of the system.
Installation must always be above the primary circuit heat exchanger.
The selected location must be on the inside of the building and in a dry place.
