NORMAL STARTUP

Some splattering may occur until pads are conditioned (may take several uses).
1. Move the unit to the place where it will be run. Do not attempt to lift or move the unit once it is filled as
damage to the unit or a large spill may occur.
When you decide where to place the unit, make sure there are no obstructions in the way that will
disrupt or block the airflow. Make sure the unit is level at all times. Keep the unit at least three feet away
from walls or other obstructions that will interfere with airflow into the unit.
2. Check to insure the drain cap is in place and secure.
3. Connect the garden hose to the brass hose adapter. Check that there is a washer in the hose connection's
female end.
4. Open the water supply valve and check that water enters the bottom through the float valve by removing
one cooling pad. Allow the unit to fill and check that the float valve completely shuts off the water.
5. If you are manually filling, remove one or more cooling pads and fill the bottom with a bucket or hose.
6. Visually monitor the filling operation to avoid overflowing and causing spill damage.
7. Plug the unit into an outlet.
8. Turn the switch to the low cool position, then to high cool if more air is desired.
CAUTION Do not run the pump without water in the bottom or you will damage the pump.
Running the pump dry will void the warranty on the pump.
