THANK YOU
Congratulations on your purchase of this versatile USHA Evaporative Air Cooler.
For optimum cooling from your cooler, fill the water tank to maximum level before
you turn on your air cooler.
Cooler Location (Important - Please Read!)
Place the cooler in front of an open door or window. Ensure that there is adequate
cross -ventilation in the room by leaving a door or window open opposite the
cooler. Following these guideline will ensure your cooler will work as effectively as
possible. Keep distance of minimum 0.5 meters from the wall.
Not an Air Conditioner (Important - Please Read!)
The evaporative air cooler is not an air conditioner as it does not use a compressor
or refrigerant gas. It should not be expected to cool as efficiently as a refrigerated
air conditioner

USER TIPS
Energy efficient, No compressor
USHA Evaporative Air Coolers are built to maximize energy efficiency and keep
costs low. Warm air is drawn into the cooler through the Honeycomb Cooling
Media. Water pumped from the tank pours over the honeycomb media. As the
warm air passes through the media, the water absorbs the heat, naturally cooling
and humidifying the air. A fan propels the cooled air out into the room. This no-
compressor system cools naturally, efficiently and inexpensively.

Evaporative Air Cooling Mechanism

The recommended maximum relative humidity
level is 60% or less, which allows a noticeable
temperature decrease. The temperature
decrease will be greater in drier climates
because higher evaporation occurs when the
humidity is low.
The evaporative air cooler should not be used
in enclosed spaces. It must be kept level and
there must be water in the water tank. The
room should have doors and windows opened
to allow free air flow. The evaporative air cooler
works best when placed near an open window,
so that outside air is drawn into the evaporative
air cooler, the air circulates in the room, then
exits via the door. The maximum cooling effect
is felt when a person is in the flow of air coming
out of the evaporative air cooler.
NOTE
When the product is used for the first time the
Honeycomb cooling media will have an odor
which will dissipate in a week or so of initial use
