Rosvola Automatic Liquid Level Controller with Dual Float, Pump Switch 70-AB 220V.

Features: 1. The base is equipped with two sections of 3/4-inch and 1-inch screw-type toothed conduits, with an L-shaped bracket for flat mounting. 2. The switch is sealed within the housing, completely moisture-proof, maintaining precise performance and extending the switch's lifespan. 3. The solid floating ball is submerged in water, maintaining a stable center of gravity, preventing it from floating on the water's surface, and ensuring high accuracy. 4. This switch has two circuits: Terminal A is used for water supply, and Terminal B is used for water pumping. 5. Meanwhile, the dual-float water level switch offers excellent performance and is easy to use. Specifications: Item Type: Water Level Controller Model: 220V 15A AC Switch Lifespan: 1 million cycles or more Water Channel Pressure: Equal to atmospheric pressure Temperature Range: 4°C ~ 80°C Principle: Using the principle of different weights, when two floating balls are immersed in water and air, the pump is automatically controlled to pump water or air depending on the water surface rise. Installation Method: 1. The optimal fixed position for the controller should be in the center of the top of the sink. If you wish to fix it to the inside of the sink, ensure that the floating ball does not hit the groove wall. 2. The hanging ball is attached to the controller wire, and the control range extends from the center of the upper ball to the center of the lower ball, which can be freely adjusted as needed.
