MAINTENANCE AND STORAGE
WARNING: ELECTRICAL SHOCK HAZARD. Disconnect the power supply before performing service or
maintenance. Failure to do so may result in serious injury or death.
Removing the cooling media
Remove the cooling pads to access the inside of the cooler.
1. Remove the bolts connecting the pad retainer bar (pad side) from the housing.
2. Cool-Space® 400 and 500 models: Remove top pads.
3. Starting with the center pad(s), tilt pads from the top and lift out of the cooler.
NOTE: Reinstall pads correctly according to the markings on the pads.
Daily maintenance
After each use, turn o the pump about 15 minutes before turning the fan o to allow the pads to drain and dry
out. This controls mildew and bacteria growth for a long and ecient pad life. Drain the water from the cooler if it
will be unused for a prolonged period of time.
Periodic maintenance
The cooling pads act as a filter to remove dust and other particles from the incoming air stream. The collected
particles and any water impurities will flow into the sump and collect there. To keep the cooler operating at peak
eciency, keep the cooling media and sump clear of debris.
Draining the water sump
Depending on how often you operate the cooler, drain the sump anywhere from every week for heavy use to
monthly for light use.
1. Close water flow valve and open drain valve or remove drain plug located at bottom of reservoir.
2. Run pump until sump is dry, and then immediately shut o pump.
3. Turn cooler o and disconnect power supply.
4. Remove cooling pads.
5. Clean out reservoir with either a towel or wet/dry vacuum.
6. Remove the water spray bar and its plug. Ensure holes are free of debris.
7. Reinstall pads and pad retainer.
Using water treatment tablets
To avoid scale and mineral buildup, use water treatment tablets periodically. Tablets are provided in the cooler’s
reservoir according to the table below. Every 3 months, add the specified number of tablets to the reservoir after
cleaning. Additional tablets are available by calling 877-244-3267.
