- Voltage: 115 Volts
- Wattage: 534 watts
Connect the power cord to a grounded 115V outlet. Do not use extension cords unless absolutely necessary and ensure they are rated for the unit's wattage.
Water Connection
Connect a water supply line to the cooler's water inlet. Ensure all connections are secure and leak-free. The unit requires a continuous water supply for evaporative cooling.
Operating Instructions
The Hessaire 4800 CFM Evaporative Cooler features a 2-speed motor and an ultra-quiet prop design for efficient and quiet operation.
Controls
Locate the control panel, typically on the side or front of the unit. It usually includes controls for fan speed and pump operation.
- Fan Speed: Select between two speeds (High/Low) to adjust airflow.
- Pump: Activates the water pump to saturate the cooling media. The pump must be on for evaporative cooling.
Starting the Unit
- Ensure the unit is properly connected to power and water.
- Turn on the water pump. Allow a few minutes for the cooling media to become fully saturated.
- Select the desired fan speed.
Optimal Performance
For best cooling efficiency, ensure adequate ventilation in the area. Evaporative coolers work best in dry climates and require an exhaust path for humid air.
The unit utilizes hi-density rigid media for 85% cooling efficiency.
Maintenance
Regular maintenance ensures the longevity and efficient operation of your evaporative cooler.
Daily/Weekly Maintenance
- Check water level and ensure continuous supply.
- Inspect cooling media for excessive mineral buildup.
Monthly/Seasonal Maintenance
- Clean Cooling Media: The unit features a high-density filter. Periodically remove and clean the cooling pads according to manufacturer instructions. This helps maintain 85% cooling efficiency.
- Drain and Clean Water Reservoir: Drain the water reservoir and clean it to prevent algae and mineral buildup.
- Inspect Pump: Check the water pump for debris and ensure it operates freely.
- Inspect Fan Blades: Ensure fan blades are clean and free of obstructions.
Winterization
Before storing the unit for the off-season, drain all water, clean the reservoir and cooling media thoroughly, and ensure the unit is dry to prevent mold and mildew growth. Store in a dry, protected area.
Troubleshooting
This section provides solutions to common issues you might encounter.
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not turn on. | No power, tripped breaker, faulty switch. | Check power cord connection, reset breaker, contact service if switch is faulty. |
| No cooling effect. | Water pump off, low water level, clogged media. | Turn on pump, check water supply, clean cooling media. |
| Water leakage. | Loose water connection, cracked reservoir. | Tighten connections, inspect reservoir for damage. |
| Unusual noise. | Obstruction in fan, motor issue, pump issue. | Inspect fan for debris, contact service for motor/pump issues. The unit has an ultra-quiet prop design, so any unusual noise should be investigated. |
