General Safety Precautions

Read and follow all instructions, cautions, and warnings. Failure to do so could result in personal injury, death, or property damage.

Unit must be in the OFF position and UNPLUGGED from the power receptacle before performing any maintenance/service or before REMOVING access panels.
Ensure the electrical power source conforms to the requirements of the evaporative cooler and local codes.
To reduce the risk of fire or electrical shock, do not expose electrical connections to water.
Do not touch electrically live components.
Ensure all power cords do not touch sharp edges, hot surfaces, or chemicals. Immediately replace damaged parts.
Never leave the unit unattended.
Continuous fill is not to be used indoors or unattended.

Operation Tips

Hessaire coolers are highly recommended for outdoor use. If used indoors, position the cooler in front of a window or open door for fresh intake air. Ensure there is an open door or window through which the air can exhaust from the room.

Clean media pads and tank frequently.
When shutting down the unit, run without the pump for 30 minutes to properly dry the media pads.

Prior to long-term storage:

Drain tank and wipe clean.
Dry and clean rigid media pads.

Indoor Use: A diagram shows an evaporative cooler placed inside a room with arrows indicating airflow out of the cooler and an exhaust airflow out of the room through an open door.

Maintenance

WARNING: Disconnect from power source before attempting any maintenance or routine service. NEVER remove any access panels while the cooler is in operation. Failure to do so could lead to SERIOUS INJURY.

Cleaning Cooler & Rigid Media Pads

The removable panel(s) and pads can be gently sprayed off to remove build-up. A soft bristle brush can also be used.

NEVER spray pads with water while the cooler is in operation. Damage can occur to the motor and will void the warranty.

Note: Vinegar is recommended for cleaning the cooler and can be periodically cycled through during normal use.

Removal Of Back Panel

Disconnect power supply. Remove the two Phillips screws from the upper back side of the cooler. Push the panel up and pull the bottom out to remove.

Removal Of Rigid Media

Once the back panel is removed, the media pads will be accessible. Note: some pads may be held in place with pins (media keepers) which will need to be removed to free up the pads.

Storage

Drain tank and wipe dry. The drain plug is located on the bottom of the cooler. Ensure pads are dry by running the fan without the pump for at least 30 minutes.
