Very little maintenance is required on the unit. Primary
maintenance is cleaning. Keeping the unit clean will do
more than any other single item to maintain your unit in
peak operating condition.
DAILY MAINTENANCE
Daily, the pump should be turned off approximately
15 minutes before the fan is turned off. This will allow
the cooling pads to dry out and help extend their life,
minimizing growth of mildew, mold, bacteria and other
odor-causing elements.
WEEKLY MAINTENANCE
At the end of the week or at a scheduled time, the unit
should be shut down and the sump tank should be
drained. Close the spray bar adjustment valve and
open the drain valve. A hose may be attached to the
drain valve to drain the water to a remote disposal area.
Once the drain valve is open, starting the pump will
drain the unit. When the pump has removed most of the
water a small amount will be left in some areas.
1.
Drain all water from the sump tank and clean
as above, ensuring that the pads and sump are
completely dry.
2. Roll up power cord and secure it so that it is not
rolled over, tripped over or caught in equipment.
3. Cover the unit completely to prevent dust build up
and store in a dry area.

MAINTENANCE
Once the sump is drained and the power disconnected,
the pads may be removed for inspection of the sump
tank. If the unit is in a dusty environment, dust may
collect in the sump tank over time.
Vacuum out dirt and any remaining water using a wet/
dry shop vacuum and wipe clean with a cloth. Inspect
and clean the inlet strainer located on the bottom of
the pump. Replace pads in correct airflow direction,
referring to label on the pads.
MONTHLY MAINTENANCE (OPTIONAL)
Place one hard water mineral treatment strip into
the bottom of the reservoir to prevent buildup due to
hard water. One four-month supply is included with
the evaporative cooler. Additional boxes of mineral
treatments can be purchased by ordering Uline model
number H-6108.
STORAGE
CAUTION! Disconnect power before removing
cooling pads from the unit!
NOTE: Power cord may be replaced only by the
manufacturer or qualified agent!
