The 255-620 Automatic Refill System provides a simple method to automatically refill an evaporation pan at specified times. It consists of an electronic water timer and an automatic float valve. The water timer switches on at a user-specified time, allowing water from an external water source to flow into the pan. The float valve will stop the water flow at approximately 8-1/2" to 9-1/2" depending upon the water pressure. The timer then shuts off until the next programmed time.
The 255-620-A needs higher (city) water pressure. The 255-620-B is suitable for lower pressure (gravity-flow) applications.
