## Description

Full description not available

## Features

- The hydraulic safety unit protects the hot water generator against the risk of bursting
- It allows water to be evacuated, following its expansion during heating, which avoids any overpressure in the water heater
- Made in France
- 5-year warranty
- For vertical electric water heaters
- Note Too much pressure in the system, they need to check their plumbing (not product, as a drop is normal on a security group). Also check that the valve is closed (big red button). If necessary, add a pressure reducer to the installation to avoid the drip problem
- Incorrect use of the valve (red button) which is then in the "open" position, incorrect adjustment of the upstream installation (too much pressure on the network)
