READ AND SAVE THESE INSTRUCTIONS!
• This is an electric device with moving components. There is the possibility of fire, electric shock, or injury to
persons. Ensure all the safety recommendations are adhered to in order to minimize this risk.
• Disconnect all power and unplug the unit before you inspect, clean or perform maintenance on the
components of the unit.
• Never reach into the unit when it is running; you could become entrapped by the V-belt or injured by the
rotating fan blades.
• The frame edges may be sharp; do not run your hand along them. Be careful and wear gloves when you
reach under the frame to inspect the PVC pipes and mesh socks.
• A GFCI (Ground Fault Circuit Interrupter) is recommended for use with this product.
• If pads and grates are removed for servicing, they must be replaced prior to operating unit.

• Pump - Little Giant 115 volt, 60 Hz, submersible, 1200 GPH
• Reservoir Capacity: 38 Gallons
• Optional Water Supply - Standard 3/4" hose connection (garden hose size)

• Evaporation Media - Chemically treated cellulose paper to resist deterioration - 8" thick pads
The Pro-Kool ® evaporative cooler is a completely self-contained, portable unit capable of delivering 15 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 fan
• Frame and housing
The bottom is made of high impact poly and holds approximately 40 gallons at normal operating level (about 6"
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, a rugged steel support frame. Four casters (2 locking, 2 regular) are
attached to the underside of the steel frame.
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 the tray and pad support plate.
The fan is powered by a belt drive 1hp electric motor. The fan draws room air through the cooling pads where it
picks up moisture and cools by evaporation. The fan blade then discharges the cooled air.
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 Operation and Maintenance section of this manual.
Water weighs about eight pounds per gallon, so when the unit is full, it weighs over 500 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.
