Package size: 21.6 x 16.5 x 11.1 cm; 250 g. The complete, improved G52 safety valve kit includes a G54 housing and a timer mechanism for the internal speed. This is useful when the robot vacuum cleaner gets stuck on an obstacle or ledge and has difficulty turning around, or when water stops flowing from the nozzle while the emergency valve is still open. (HIGH COMPATIBILITY): The replacement emergency valve kit fits perfectly on Zodiac Polaris models 180, 380, 280, 480 PRO, 3900 Sport, Vac-Sweep 380, Vac Models-Sweep 280, and 280. (Easy to assemble): The G52 emergency valve is ready to install and opens every 3 minutes for 30 seconds to flush out the cleaning product by reversing the cleaning direction. The valve also has the ability to free the device from tight spaces if it gets stuck.
