Important Operation Warnings:
  • The RainFlo GP-400 is designed for periodic use and is not intended for continuous operation. The recommended duty cycle is up to 4 hours ON and 1 hour OFF. DO NOT RUN DRY.
  • Exceeding recommended running time can cause excessive wear on pump seals shortening the life of your pump.
  • The GP-400 must be placed in water at least 2" deep to begin pumping. Pump should be totally submerged for proper cooling when the pump is operated for extended periods of time.
  • When the GP-400 is used near a swimming pool or garden pond the power supply must be equipped with a ground - fault interrupter circuit
  • Do not let the pump freeze in wintertime. This may cause cracking or distortion that may destroy the pump and void the warranty.
