1. Product Overview
The Honeywell CO60PM Evaporative Air Cooler, also known as a swamp cooler, is designed for both indoor and outdoor use. It provides a powerful 1540 CFM airflow, making it ideal for cooling large open rooms, patios, BBQ areas, garages, decks, backyards, or warehouses. This unit combines three appliances in one: an evaporative air cooler, a fan, and a humidifier, offering an energy-saving cooling solution.
Evaporative air coolers reduce temperature through water evaporation, providing a moist, cool breeze without spraying water on surfaces. They are most effective in hot, dry climates where humidity levels are typically below 60%.

3. Setup and Installation
3.1 Unpacking
Carefully remove the evaporative air cooler from its packaging. Inspect the unit for any signs of damage. Retain all packaging materials for future storage or transport.
3.2 Placement
Place the unit on a flat, stable surface. Ensure there is adequate space around the unit for proper airflow. For outdoor use, position the cooler in a well-ventilated area, ideally where it can draw in fresh, dry air.

3.3 Filling the Water Tank
The CO60PM features a 15.9-gallon water tank. You can fill it manually or connect it to a continuous water supply.
- Manual Fill: Open the water inlet cover on top of the unit and pour clean water into the tank until the water level indicator reaches the 'MAX' line. Do not overfill.
- Continuous Water Supply: Connect a standard garden hose to the water hose connector located on the side of the unit. Ensure the connection is secure to prevent leaks. The unit will automatically maintain the water level.

3.4 Power Connection
Plug the unit into a standard 120V AC electrical outlet. The CO60PM is equipped with a GFCI cord for safety, especially during outdoor use.
4. Operating Instructions
4.1 Control Panel
The unit features a simple control panel with rotary knobs for fan speed and cooling function.
4.2 Fan Speed
Turn the 'Speed' knob to select your desired fan speed: Low, Medium, or High. The fan circulates air, providing a breeze even without the cooling function activated.
4.3 Evaporative Cooling
To activate evaporative cooling, ensure the water tank is filled. Turn the 'Cool' knob to the 'ON' position. The water pump will begin to wet the honeycomb cooling pads, and the fan will blow air through the moistened pads, creating a cooler, humidified airflow.

4.4 Oscillation
Some models may include an oscillation feature to distribute cool air more widely. Refer to your unit's specific controls for this function.
4.5 Important Considerations
- This is an evaporative cooler, not an air conditioner. It will not cool as efficiently as a refrigerated AC unit.
- Optimal performance is achieved in hot, dry climates (humidity below 60%).
- Ensure adequate ventilation when operating indoors to prevent excessive humidity buildup.
5. Maintenance
5.1 Cleaning the Water Tank
Regularly clean the water tank to prevent mold and mildew growth. Drain any remaining water and wipe the tank clean with a soft cloth. For thorough cleaning, a mild detergent can be used, followed by rinsing.
5.2 Cleaning/Replacing Cooling Pads
The triple-sided honeycomb cooling pads should be inspected periodically for mineral buildup or debris. If heavily soiled, they can be gently rinsed with water. Replace pads if they are damaged or show significant wear, typically every 1-2 years depending on usage and water quality.

5.3 Exterior Cleaning
Wipe the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not turn on | No power supply; GFCI tripped | Check power cord connection; Reset GFCI if tripped. |
| No cool air | Water tank empty; Cooling pads dry; Pump malfunction | Fill water tank; Ensure 'Cool' function is on; Check water pump for operation. |
| Unpleasant odor | Stagnant water; Mold/mildew on pads | Drain and clean water tank; Clean or replace cooling pads. |
| Water leakage | Overfilled tank; Loose hose connection | Do not overfill; Securely tighten hose connection. |
