How the Storm Extreme Works

The Storm Extreme dehumidifier utilizes its integral humidistat to monitor the conditioned space. Once conditions are outside the desired setpoint, the compresser energizes and air is drawn across an evaporator coil. The evaporator coil is cooler than the dew point of the air so the water vapor will turns into liquid condensation. The air is then reheated through the condenser coil and distributed back into the room.


Operation Notes

  • Always make sure that the unit is operated, transported, and stored on a stable surface.
  • For maximum efficiency, operate the unit with all windows and doors closed.
  • Do not place the unit anywhere that may block the inlet or outlet airflow.

Drain Hose Notes

  • The Extreme is equipped with an external drain line connection, making it easy to plug in.
  • The drain line can be directed outside or into any sink, drain, etc.
  • For more effective draining, uncoil the entire hose before using.
  • Never place the end of the hose higher than 15 feet.
  • Always ensure that the drain hose is not blocked prior to use.

Transportation Notes

  • Always secure the dehumidifier during transportation
  • If the unit is transported vertically, return it to a normal horizontal position, and let sit for 30 minutes prior to use.
