A. Unpacking the PORT-A-COOL® unit. The pneumatic PORT-A-COOL® unit models ( PAC2K36AD, PAC2K24AD, PAC2K16AD), are packed according to the model. The 36” reaction fan model (PAC2K36AD) is crated on a wooden pallet. This model comes completely assembled and thus weighs in excess of 460 lbs.

WARNING: use extreme caution when connecting or disconnecting compressed air!! Before connecting compressed air to the PORT-A-COOL® unit be sure that both the Jet Fan or Air Mover and the Pump shut-off valves are closed. The air is connected by way of a Crow’s foot type bayonet connector.
There are three primary considerations when deciding where to place the PORT-A-COOL® unit. 1) Fresh Air Supply - The rear of the PORT-A-COOL® unit (pad area) must be placed so as to insure a smooth, uninterrupted supply of fresh air.

PORT-A-COOL IS ATTACHED TO A GOOD GROUND TO ELIMINATE STATIC ELECTRIC CHARGES. Only the 36” reaction fan model (PAC2K36AD) has a rotating fan to move the air. This unit is started by slowly opening the large 1/4 turn air valve on the control panel on the side of the unit.
Very little maintenance is actually required on the PORT-A-COOL® unit. Most of the maintenance on the PORT-A-COOL® unit is cleanliness. Keeping the PORT-A-COOL® unit clean will do more than any other single item to keep your new PORT-A-COOL® unit in peak operating condition. The rugged, corrosion-resistant construction of the PORT-A-COOL®...
PORT-A-COOL® unit does not operate properly. The PORT-A-COOL® unit consists of three systems. It is important to determine which system of the PORT-A-COOL® unit the problem is associated with. This may not always be obvious in that certain problems may be associated with more than one system.
If the air has a low relative humidity when entering the PORT-A-COOL® unit, then it has the ability to hold more moisture, and will thus evaporate more water and cool more effectively.

The PORT-A-COOL® unit utilizes the same phenomenon, but in the most efficient manner possible. B. Humidity and Evaporative Cooling. A cubic volume of air at a certain temperature and pressure has the ability to absorb and hold a certain amount of water vapor.

COOL® unit has incorporated all of these features and more. As explained in PART B of this section, the effectiveness of the PORT-A-COOL® unit is best appreciated when it is above 85°F and below 75% relative humidity. By the tıme the outside temperature reaches 85°F, the humidity is almost always below 75%.
