The sensor plug, position 22, closes the opening for the temperature sensor in the body of the Elecro G2 heat exchanger. It is used in installations where the temperature sensor is not fitted, or as a replacement for a damaged original plug.
A correctly installed plug prevents water from leaking out of the exchanger body and maintains the operating pressure in the system. A damaged or missing plug causes a visible leak at the sensor opening.
The original plastic material withstands the temperatures of the heated pool water, pool chemicals and mechanical stress during normal exchanger operation. Replacement requires no professional tools or a technician’s service intervention.
