Essick Air M150 User Manual

Select the area you wish to cool.  Evaporative coolers 
work best near a partially opened door or window to 
draw in fresh air.  An equal amount of air should be 
discharged out of the room to dispel heat and humidity.  

Fill the reservoir from the back.  The reservoir holds 
5 1/2 gallons of water.   DO NOT OVER FILL.  Water 
will leak out and could cause water damage to the sur-
rounding area.  If the reservoir runs dry, it will not harm 
the pump.  When transporting the unit to a different 
location, be very careful not to spill the water.  It is best 
to re-locate the cooler, and then add water.  

Included is a fl oat for continuous fi ll.  To attach the 
fl oat, remove the back grille.  Remove the nuts from 
the fl oat and insert the fl oat into the water shield and 
then through the hole in the housing.  Secure the fl oat 
with the nut that was removed.  You may connect ei-
ther a 1/4 inch hose or a garden hose using the garden 
hose adapter.  Adjust the fl oat so that the water level is 
about an inch below the top of the reservoir.  Reinstall 
the back grille.

Plug the electrical cord into a 115-120 volt grounded 
outlet.  You may operate your cooler on one of three 
speeds: low, medium or high.  Turn the switch knob 
clockwise to activate the pump and fan.  This will cool 
the air.  Turn the switch counterclockwise to operate 
the cooler as a fan only (pump will be off).

Unpack your cooler and install the casters.  Slip the 
stems of the casters into the holes provided in the bot-
tom of the front and back grille.

No oil or lubrication is necessary.  The motor is perma-
nently lubricated at the factory.

No oil or lubrication is necessary.  Clean any debris 
from under the pump in the inlet area.

Remove the fi lter from the rear grille and rinse with 
water.  Be careful not to damage the fi lter!  The fi lter 
should be replaced every two years or if it becomes 
clogged.

Drain and clean the water tank.  To drain, remove the 
back grille and disconnect the clear hose from the 
black tube.  Turn unit on cool and pump out most of 
the water.  Wipe dry and clean with a towel.  Before 
reattaching the back grille, reconnect the clear hose to 
the black water tube.

1. The pump hose may have worked loose.  Check the 
connection at the pump and at the water tube located 
in the back grille assembly.  Reconnect pump hose if 
necessary.

2. The water tube may be blocked.  Remove the tube 
and clean it out. Make sure water holes are clear.

3. The pump or switch may be defective.  Replace 
pump or switch, if necessary.

1. Verify there is 115-volt power at the electrical outlet.  
Check the fuse or breaker.

1. The fan switch or motor may be defective.  Replace 
if necessary.
