HESSAIRE M150 Portable Evaporative Cooler

1. Introduction

This manual provides essential information for the safe and efficient operation, maintenance, and troubleshooting of your Hessaire M150 Portable Evaporative Cooler. This unit is designed to provide effective cooling in various environments, including shops, garages, and outdoor covered areas.

The M150 features a high-visibility green trim and power cord, adjustable front louvers for multi-directional airflow, and an oscillation feature to broaden air flow coverage. It supports continuous water fill with an included hose adapter and utilizes a proprietary swept-wing prop design for optimal airflow. It is most efficient in low humidity climates and can cool up to 950 square feet with 3100 CFM.

2. Important Safety Information

Please read all instructions carefully before operating the unit. Failure to follow these instructions may result in electric shock, fire, or serious injury.

• Always ensure the unit is placed on a stable, level surface.
• Do not operate the cooler with a damaged cord or plug.
• Do not immerse the unit, cord, or plug in water or other liquids.
• Unplug the unit from the power outlet before cleaning, performing maintenance, or when not in use.
• Keep children and pets away from the unit during operation.
• Ensure proper ventilation. The cooler must be positioned in front of an open window or door if it is to operate effectively. Always ensure that there is another open window or door through which the air can exhaust from the room.
• Do not block air inlets or outlets.
• Use only with a properly grounded outlet.
• Proposition 65 Warning: This product may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

3. What's Included

Your Hessaire M150 Portable Evaporative Cooler package includes the following items:

• Hessaire M150 Evaporative Cooler Unit
• Owner's Manual (this document)
• Casters (4 total: 2 locking, 2 non-locking)
• Brass garden hose adapter

4. Assembly

Hessaire Coolers are pre-assembled and ready to operate with minimal setup. Follow these steps to prepare your unit for use:

1. Carefully remove the unit from its packaging.
2. Install the four casters into the designated slots at the bottom of the unit. Ensure they are securely fitted.
3. Once the unit is in its desired location, lock the two locking wheels to prevent the cooler from moving due to air velocity during operation.

5. Initial Setup

Before first use, the pump must be primed according to instructions. Ensure the cooler is positioned correctly for effective operation.

5.1 Water Filling Options

The M150 offers two convenient ways to fill its 10.3-gallon water reservoir:

• Manual Fill: Open the small panel on the front of the unit to access the fill port. Pour water directly into the reservoir until the water level indicator shows it is full. This provides up to 4 hours of self-contained cooling.

  

• Continuous Fill: For extended operation without manual refilling, use the included brass garden hose adapter. Attach one end to a standard garden hose and the other to the adapter port on the side of the cooler. The unit features a float valve that automatically regulates the water level.

  

5.2 Positioning for Optimal Performance

For the most effective cooling, position your Hessaire M150 in front of an open window or door. It is crucial to also have another open window or door through which the humidified air can exhaust from the room. This creates a cross-ventilation effect, allowing fresh, dry air to enter and humid air to exit, maximizing the evaporative cooling process.

6. Operating Instructions

The Hessaire M150 features an easy-to-operate mechanical control panel located on the top of the unit.

6.1 Control Panel Overview

The control panel consists of rotary switches for intuitive operation:

• Motor Speed Dial: Turn this dial to power on the cooler and select your desired fan speed: Low, Medium, or High.
• Pump Switch: Turn the pump switch ON to activate the water pump, which saturates the internal Xel50 Cooling Media. For fan-only operation, ensure the pump switch is OFF.
• Air Swing Delivery System (Oscillation) Switch: Turn this switch ON or OFF for automatic oscillation of the internal fan. This feature helps distribute cool air more evenly across a wider area.

The unit can be used in fan-only mode by keeping the pump switch off. This is useful for circulating air without adding humidity.

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your evaporative cooler.

7.1 Filter Cleaning

Ensure the cooling media (filter) is kept clean throughout the summer season. A dirty filter can reduce cooling efficiency and airflow.

7.2 Daily Operation Tips

At the end of each day of use, run your cooler on FAN ONLY for 30 minutes. This helps to dry out the cooling media, preventing mold and mildew growth and extending its lifespan.

7.3 Winter Storage

Before storing your cooler away for the winter season, perform the following steps:

1. Drain the water tank completely and wipe it clean to remove any residue.
2. Clean the cooling media thoroughly.
3. Reassemble the unit and run it on FAN ONLY for 30 minutes to ensure the cooling media is completely dry before storage.
