To operate the Cool Boss for cooling
:
Before starting the Cool Boss, verify that the Media and the Media Holder Splash Guard is secured
in place. This will reduce the chances of water splashing out of the Cool Boss and creating a
slipping hazard in front of the Media.
Open a Door or Window, if using the Cool Boss indoors. Sufficient airflow for intake and exhaust is
critical.
Verify that the Cool Boss is connected to a Water Source through the 3/4 inch Hose Inlet or the
Water Reservoir is full.
Verify the Casters are locked to prevent the Cool Boss from moving with additional thrust from the
Fan.
Plug-in the Cool Boss electrical cord to an appropriate electrical outlet.
⚠
CAUTION Verify there is water in the Water Reservoir before moving the Water Pump
Switch to the On position. If there is insufficient water in the Reservoir, the Pumps’
internal low-water switch will keep the Pump in the off condition.
On the Cool Boss Control Panel, move the Water Pump rocker switch to the on position. Verify
water is making its way through and saturating the Media.
Once the top 30% of the Media is saturated, rotate the Fan Speed Switch to 1 applying power to
the Fan.
⚠
WARNING Rotating Fan Blades! Keep hands, fingers and loose clothing away from the Fan
when it is running.
Verify the fan is operating and cool air should begin to move through the Cooler exhaust. If the Fan
is operating normally, select the desired power setting.
To use the Swing Louver function :
⚠
CAUTION
Before applying power to the Swing Louvers, verify that there is nothing that will
physically block or impede the motion of the Louvers.
