WHY USE EVAPORATIVE COOLERS IN YOUR WORKPLACE?
• The WayCool®evaporative cooler requires little space, has a low initial cost, is
inexpensive and simple to operate and requires minimal scheduled maintenance.
• Due to the design and construction of the cooling pads, cooling efficiency is
normally maintained near optimum throughout the life of the pads, which can easily
last for about two seasons with proper care.
• In many cases, evaporative coolers are a better solution than mechanical
refrigeration systems because they are more economical to operate and maintain
and do not use environmentally sensitive and costly refrigerants.

HOW EVAPORATIVE COOLING WORKS
Figure WC-1HP-DHL.02 - Evaporative Cooling Principle
Evaporative cooling is the same process your body uses to cool itself. When you perspire, and air moves
across your skin, a portion of the perspiration (water) evaporates. Evaporation requires heat to change liquid
water-to-water vapor and this heat is taken from your skin, producing the cooling effect.
In an evaporative cooler, the cellulose cooling pads take the place of your skin, water instead of perspiration
wets them and a fan moves the air. The air blows across the cooling pads and evaporates moisture. Heat is
drawn from the pads and the air, dropping the air temperature and producing the cooling effect. The cooled
air is then forced through a building or space and displaces the warm air out building openings, cooling the
surroundings. In addition, air velocity increases the cooling effect as it moves over the skin of people in the
airflow path.
WayCool®evaporative coolers are portable and use the latest technology to provide large volumes of cool
air, efficiently and inexpensively for cooling small to medium size areas. Simply adding more units can
accommodate larger areas. With proper sizing and application, a WayCool®portable evaporative cooler can
lower the effective air temperature by up to 20°. Even in high humidity, the efficiency of the WayCool®
evaporative cooler provides effective cooling.

The WayCool®evaporative cooler is a completely self-contained, portable unit capable of delivering 40 MPH
velocity of air with a temperature drop of up to 20°. The unit is composed of:
• Level-controlled water supply system
• Cooling pad assembly
• Motor-driven blower and ductwork
• Controls
• Frame and housing
The bottom is made of high impact ABS plastic and holds approximately 24 gallons at normal operating level
(about 5" deep).
A float-operated valve automatically maintains proper water level when the unit is connected to a water
supply.
The bottom rests on, and is fixed to, an aluminum cradle. The bottom, in turn, is secured to the aluminum
frame. Four casters (2 locking, 2 regular) are attached to the underside of the aluminum cradle.
A pump draws water from the bottom and discharges it through the vinyl hose to the PVC pipes located
above the cooling pads. The PVC pipes distribute water onto the top of the cooling pads; saturating them.
Excess water drips back into the bottom through the holes in the cooling pad support channels.
The cellulose cooling pads sit in support channels and are held in place by plastic retaining grates. The
grates also help prevent damage to the cooling pads. Two pad sections fit in each side of the unit (total eight
sections) to totally enclose the unit.
The blower is hung from the top of the frame and powered by a belt driven 1HP electric motor. The blower
draws room air through the cooling pads where it picks up moisture and cools by evaporation. The blower
then discharges the cooled air.
Note: It is important the cooled space has sufficient air openings so the warmer air can flow out and
be replaced by the cooled air. A closed-in space or high humidity will reduce the cooling effect. See
Unit Placement and Other Considerations in the “Operations and Maintenance” section of this
manual.
A screen covers the discharge duct to prevent foreign objects from entering the blower. A threaded rod
screws through a threaded brace above the screen to hold the blower duct in position. A plastic knob
secures the blower duct to the rod. The blower duct is made of a tough, durable plastic and can be manually
rotated 360 degrees to provide cool air in any direction without moving the unit.
Note: Water weighs about eight pounds per gallon, so when the unit is full, it weighs over 375
pounds. During setup and before startup, place the unit in the desired location and then fill the
bottom. Do not attempt to lift the unit once it is filled and be careful to avoid spills when moving it;
even over smooth ground. Do not try to push it over rough or soft ground as you can overstress the
wheels and frame and cause structural and component damage, which is not covered by warranty.
