Hose Adapter
Our convenient hose adapter allows you to have
continuous water fill on your cooler.
Air Intake
These coolers have 3 media panels instead of a
single panel found on most mobile coolers. 3
panels allow more air-intake area and reduce
pre-rotation of the air to the prop, which
translates into lower static pressure and more
efficient air delivery to the prop.

Cooler Maintenance
Cleaning Cooler and Rigid Media Pads
The removable panel and media pad can be
sprayed out on the ground to clean pad. Use
light pressure when spraying pads. You can use
a soft bristle brush to gently wipe away deposits.
NEVER spray pads with water while cooler is
operating, and fan is running. This can cause
damage to motor and will void the warranty.
Removal of the Back Panel (Disconnect power
supply before this procedure.)
Removal and Replacement of Cooling Media
1. If your cooler includes media pins,
remove by unscrewing/pulling out the
disc.
2. Remove media pad. Replace with new
pad.
3. Reinstall the back panel and you are
ready to use the cooler again.
Go to www.hessaire.com for replacement
videos and tips for eliminating any odor.
Draining the Cooler Tank
1. Pull or unscrew drain plug/cap from drain
assembly.
2. Tip unit to ensure all water exits the unit.
3. Replace drain plug.
Use all precautions and
disconnect from power source
before performing any
maintenance.

spill over into airstream---Clean spreaders.
