# What Should You Pay Attention to When Installing an Evaporative Air Cooler? – Rundongfang

Do you know much about evaporative air coolers? There are quite a few types of air conditioners, and when choosing one, you should learn more about the model specifications and functions of the unit to select a suitable type. Evaporative air coolers have always been one of the types that users pay close attention to. So, what are the key considerations when installing a [Dongguan evaporative air cooler](https://rundongfang.com/evaporative-air-cooler)?

## Evaporative Air Cooler Installation Checklist

**Quick answer:** when installing a Dongguan evaporative air cooler, keep the air inlet to exhaust opening ratio at least 1:1, keep the unit away from odor sources such as bathrooms and kitchens, use a bracket that supports the full weight of the unit and ducts, check for obstacles 2.5 m above the floor along the duct path, keep 280-330 mm between the unit body and the wall, and mount the indoor controller no less than 1.5 m above the floor.

| Checklist item | Requirement |
| -------------- | ----------- |
| Air inlet vs. exhaust openings | Ratio at least 1:1; open outlets at 3 m or more, or add industrial exhaust fans |
| Installation environment | Smooth, fresh airflow; away from bathrooms, kitchens and odor or fume sources |
| Mounting bracket | Supports full weight of main unit, air ducts and maintenance personnel, verified level |
| Duct path clearance | No obstacles at 2.5 m above the floor; ducts and supports laid out smoothly |
| Unit-to-wall distance | 280-330 mm depending on site conditions |
| Indoor controller height | No less than 1.5 m above the floor |

1. An evaporative air cooler works by using heat exchange through water evaporation to lower the temperature, then delivering the cool air indoors through ducts while expelling the hot indoor air outside, creating air convection. Therefore, there must be sufficient air outlets indoors; the ratio of air inlets to exhaust openings should be at least 1:1. If there are many heat-generating devices indoors with no air outlets, it is recommended to open adequate air outlets at a height of 3 meters or more, or install industrial exhaust fans to draw out the hot indoor air, so as to achieve the actual effect of ventilation and cooling.

　2. The installation environment should maintain smooth, fresh airflow. It must not be installed near sources of peculiar or foul odors, or near kitchen fume exhausts, such as bathrooms, kitchens, etc.

3. When choosing the installation location for the evaporative air cooler, ensure that the mounting bracket can support the full weight of the main unit, the air ducts, and maintenance personnel.

4. After determining the installation method and location on site, measure the exact dimensions of the main unit’s installation position, and determine whether the air duct will enter the room through a wall or through a window. If indoor air supply is required at certain positions, air ducts must be laid out; pay special attention to whether there are obstacles at a height of 2.5m from the floor, and whether the air ducts and duct supports can be laid out smoothly.

　　Before installing the bracket for the evaporative air cooler, use a spirit level to check the level. The mounting bracket must remain level and must not tilt. The distance between the unit body and the wall should be 280-330mm (depending on the site conditions), and the indoor controller should be no less than 1.5m above the floor.

### How much air outlet area does an evaporative air cooler need?

The ratio of air inlets to exhaust openings should be at least 1:1. In rooms with many heat-generating devices and no outlets, open adequate outlets at a height of 3 meters or more, or install industrial exhaust fans to draw out the hot indoor air.

### How far should an evaporative air cooler be from the wall?

The distance between the unit body and the wall should be 280-330 mm depending on site conditions, and the mounting bracket must remain level with no tilt.

### Where should the indoor controller of an evaporative air cooler be mounted?

The indoor controller should be no less than 1.5 m above the floor.

### Can an evaporative air cooler be installed near a kitchen or bathroom?

No. The installation environment must maintain smooth, fresh airflow and must not be near sources of peculiar or foul odors or kitchen fume exhausts, such as bathrooms and kitchens.
