Safety Rules

1.Read instructions carefully.

2.Electrical hook up should be done by a qualified electrician, so that all electrical wiring will conform to your local standards.

3.Always turn OFF POWER and UNPLUG motor and pump inside the cooler before installing or performing any maintenance.

4.Your cooler will run on either 120V or 240V A.C., single phase, 60 Hz (cycle) current.

5.Motor and pump have a grounded, molded plug and an automatic thermal overload switch which will shut motor off when it over- heats. The motor will restart automatically when it cools down.

6.Pump receptacle is for grounded evaporative cooler pump only. Do not plug anything else into receptacle.

WARNING: To reduce the risk of fire or electric shock, do not use this fan with any “solid-state fan speed control device.”

Evaporative Cooling

Evaporative cooling is nature’s way of cooling. When air is moved over a wet surface, water is evaporated and heat is absorbed. When stepping out of a swimming pool with the wind blowing, evaporative cooling makes you feel cool, even though the air may be warm. The human body itself is cooled primarily by the evaporation of perspiration.

This unit works on the same principle. Air is drawn across wet filter pads where the air is cooled by evaporation and then circulated throughout the building. It is this combination of cooled air and the movement of air over the skin which makes it feel cool.

Unlike refrigeration systems which recirculate the air, an evaporative cooler continually brings in fresh air while exhausting old air. You are completely replacing the air every 2 to 4 minutes by opening windows or doors or a combination of both. The air is always fresh, not stale, laden with smoke and odors as happens with refrigerated air conditioning.

Operation

For the best cooling performance, if the pads are dry, pre-wet the pads by running the pump for a few minutes before starting the blower.

These coolers may be used without water for ventilation purposes. When outside air is cool (for example, at night) or when humidity is high, the water pump can be turned off.

A cooler can also be installed with a thermostat and attic exhaust dampers to provide completely automatic operation.

Open Windows To Exhaust Air

An often misunderstood concept of evaporative cooling is the amount of air that should be exhausted. How much should you open your windows? The fact is that most people do not open their windows enough. The following two methods will help you determine the amount to open your windows.

CFM Method

You should allow an opening of at least 2 square feet (288 square inches) for each 1000 CFM rating of your unit. Example: At 3654 CFM, model 4001 DD with a 1/2 hp motor requires 7.3 square feet (1052 square inches) of opening (3654/1000 * 2 = 7.3). Multiply the number of windows by window width in inches and divide this into the number of square inches required for your size unit. This will give you the height to open windows. In this example, four 36 inch wide windows should be opened 7.3 inches each.
