The evaporative air
cooler will not start
The evaporative air
cooler is not cooling the

POSSIBLE CAUSES
The evaporative air cooler is unplugged.
The fuse is blown/circuit breaker is tripped.
Power failure
The water tank is not in the proper position.
Airflow is restricted.
The water tank is empty.
The air filter is dirty.
The relative humidity in the room is too high.
The Mode control is set to Natural.
Remote control battery needs to be replaced See "Installing/Replacing the Battery in the Remote
Remote not pointed at sensor on
evaporative air cooler or sensor is blocked.
RECOMMENDED SOLUTIONS
Make sure the power supply cord is plugged into
a grounded 3-prong outlet. See the "Electrical
Requirements" section.
Check the house fuse/circuit breaker box and replace
the fuse or reset the breaker. See the "Electrical
Requirements" section.
In the event of a power failure, the evaporative air cooler
will immediately stop. When power is restored, the vent
louvers will close, then the evaporative air cooler will
beep and automatically resume operation at the previous
settings after approximately 30 seconds.
Securely seat the water tank in place.
Make sure there are no curtains, blinds, or furniture
blocking the front of the evaporative air cooler.
Fill the water tank and be sure Cool mode is on. For
added cooling power, add ice cubes to the water tank,
or use the ice packs (on some models).
Clean the air filter.
The cooling function of the evaporative air cooler is most
effective if the relative humidity level is below 75%. For
added cooling power, add ice cubes to the water tank,
or use the ice packs (on some models).
This is normal. For a steady, consistent fan speed, set
the Mode control to Normal.
Control".
Be sure to point the remote control torward the sensor
on the evaporative air cooler. Make sure that the path
between the remote control and sensor is not blocked
by furniture or other objects.
