SIGNAL WORD DEFINITIONS DANGER DANGER indicates an imminently hazardous situation which, if not avoided, WILL result in death or serious injury. WARNING WARNING indicates a potentially hazardous situation which, if not avoided, COULD result in death or serious injury. CAUTION in death or indicates serious injury CAUTION a potentially hazardous situation which, if not avoided, MAY result in minor or moderate injury.
CAUTION Do not connect the COOL-SPACE® unit to any water source where water pressure exceeds 60 psi. This will cause permanent damage to the unit. 3.2 Connecting the electrical supply: All models utilize standard 120-volt power supply. The unit should be plugged into a fused or circuit breaker protected 20 amp, 120 volt, 60 Hz circuit. If the unit is for overseas operation or is custom built for a specific application, please consult the factory for proper configuration.
4.0 Operating procedures: There are 3 factors to consider when determining where to place the COOL-SPACE® unit. 1. Fresh air supply: The inlet side of the unit (pad side) requires a constant, uninterrupted supply of fresh air for maximum performance. A distance of 3 ft clear space is recommended. 2. Discharge air flow: The cool air discharged from the unit should be free of obstruction to allow the air to circulate in order to maximize the cooling zone. 3.
4.2 Starting the fan: Turn the fan switch to HIGH speed on start-up, allow motor to reach maximum speed, then set at Medium or Low. IMPORTANT DO NOT flood the pads with water, keep them moist. New pads take a few days to become completely saturated. It is normal to have several dry streaks on the face of the pads about 1 or 2 inches wide. If the streaks are larger or unevenly spaced, adjust the flow control knob to allow more water to flow to the pads.
1. Use a wrench to remove the (2) bolts connecting the pad retainer (pad side) to the housing. 2. Each pad can be tilted out of the unit and lifted out of the drain tray. Note: Reinstall pads correctly. 5.2 Daily maintenance: When shutting down the COOL-SPACE® unit at the end of each workday, the pump should be turned off approximately 15 minutes before the fan is turned off. This will allow the pads to drain and dry out.
5.4 Storage: 1. Remove the pads, as described in 5.1.1, clean with a soft brush and water to remove dust and debris. 2. Drain sump using above procedure and wipe dry. 3. Store the COOL-SPACE® unit in a dry area and cover if possible to prevent dust build-up. 6.0 Troubleshooting/Repair: 6.1 Troubleshooting: WARNING ELECTRICAL SHOCK HAZARD Disconnect the power supply before performing any service or maintenance on the unit. Failure to do so may result in serious injury or death.
Direct & Belt Drive Models Problem Fan won't run and makes no sound. Check Power cord, extension cord, switches, circuit breaker. Fan motor won’t run and makes a humming sound. Blade in contact with shroud. Motor stalled (will not turn by hand). Motor stall. Check power source for min. 115v/20 amp. Extension cord. Extension cord gauge too small. Inlet air obstructed or too close to wall. Faulty motor. Switch making good contact. Breaker trips or fuse blows when fan is started.
Water System The water delivery system consists of three primary elements: 1) Water Distribution System, 2) Spray Bar Assembly, 3) Pump, Troubleshooting of this system is fairly simple. The water Distribution System consists of two assemblies: A) The Water Inlet Assembly, B) The Hose & Valve Assembly. The Water Inlet Assembly is made up of three components: 1) The brass bulkhead fitting, 2) The float valve connection hose, 3) The float valve assembly.
Pump Problem Pump motor will not run when switch is turned on. Check Turn fan on to check for power. Is water level high enough to make the lowwater cut-off circuit. Pump motor hums when switch is turned on, but does not pump water. Pump makes loud noise while running. Obstruction in impellar. Pump motor failure. Breaker trips or fuse blows when switch is turned on. Pump won’t run and power is available. Pump is functional. Pump runs but does not pump water. Object(s) in impellar, impellar loose.
6. Visually align the motor pulley and fan pulley by using the belt as a reference. Adjust the motor pulley in or out to align. Tighten the motor pulley. 7. Loosen the four bolts that secure the mounting bracket to the upright. 8. Lower the bracket slightly until the belt is tight (but not tight enough to overload the motor) and then tighten the four bracket bolts. 9. Replace the motor wires as marked from step # 5. Replace wire ties to prevent cord from getting in fan blade. 10.
4.) Remove pump from water sump and install new pump. Reverse the above procedures to reconnect the wiring, lift pump bracket and reconnect the hose. Secure wires to fan frame with wire ties to clear the fan blades. 5.) Reinstall cooling pads and guards, reconnect power and test pump. 6.3 Technical support: Technical support and service is available directly from your distributor or COOLSPACE® Technical Support Hot Line at 1-800-557-5716. 7.

9.0 How evaporative cooling works: In order to have an understanding of how the COOL-SPACE® portable evaporative cooler works a basic understanding of psychrometrics is necessary. Psychrometrics is the branch of thermodynamics devoted to the study of air and water vapor mixtures. The psychrometric chart is a graphical representation of properties of moist air. To illustrate how the COOL-SPACE® unit operates, some of the relevant properties are described in this section followed by a sample application.
Dew-point temperature is the temperature to which a given sample of air must be cooled so that moisture will start condensing out of it. When air is saturated, the dry-bulb, wetbulb and dew-point temperatures will all be equal. The horizontal lines in Figure 3 show the dew-point temperature on the psychrometric chart. Figure 3. Relative humidity is the amount of moisture in the air relative to the amount of moisture the air would hold if saturated at that dry-bulb temperature.
The following example illustrates the use of the psychrometric chart as it relates to evaporative cooling. Since all of the items described above are properties, any two of them describe a state point on the psychrometric chart. Once this point is determined, the values of all the other properties can be read from the chart. Figure 5 below shows a Mollier type psychrometric chart for atmospheric pressure. The dot shown in Figure 5 is a state point.
