Cool Boss Evaporative Air Cooler
25
P/N 5900275 — January 2022 — Rev. A
To operate the Cool Boss for cooling
:
Before starting the Cool Boss, verify that the Splash Guard over the Media 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 two locking Casters are locked to prevent the Cool Boss from moving with additional
thrust from the Fan.
Plug-in the Cool Boss.
Press the
On-Off
button on the Cool Boss Fan Controls. Refer to the Status Display on the
Control Panel to review the current settings.
Press the
Cool
button once to supply power to the Cooling Pump and the Fan. The
Power
and
Cool
indicators will light. Water will begin to propagate through the Cooling Media.
Important
The Fan will not rotate for up to a minute after pressing Cool
. This
allows water to propagate through and saturate the Media prior to the Fan pulling
air through it.
Press
Speed
to adjust the Fan power setting to Low. Leave the Fan Control on low until the top
≈30% of the Media becomes saturated (30 seconds minimum). Once the top 30% of the Media is
saturated the Fan speed may be increased.
Verify the Low Water Indicator is off on the Status Display. If the Low Water indictor is on, verify the
water source is connected and providing water under pressure. If filling manually, turn off the Cool
Boss, unplug it from power and fill the Reservoir.
⚠
CAUTION
Make sure there is water in the Water Reservoir before pressing
Cool;
if not, the
Pumps’ internal low-water switch will keep the Pump in the off condition.
⚠
WARNING
Rotating Fan Blades! Keep hands, fingers and loose clothing away from the Fan
when it is running.
Press the
Swing
button once to activate the Vertical Louvers. The Vertical Louvers will begin to
move left and right dispersing the cool air. Press the
Swing
button again to deactivate the Swing
function.
⚠
CAUTION
Do not attempt to grab or push objects into the Vertical Louvers while they are in
motion. The Vertical Louvers may also be damaged by attempting to move them
when the Cooler is in the off condition. Such damage is not covered under
warranty.
