How to install an Evaporative Cooler


An Evaporative Cooler is low cost cooling system that can be installed instead of an Air Conditioner. Although the Evaporative Cooler appears to be quite bulky it is easy to install. It will be useful if you have an assistant with you to do the heavy lifting.  Evaporative Cooler is can be installed on the roof or in the window. Installing the Evaporative Cooler on the roof is common but there are many problems associated with it.  Evaporative Cooler sometimes might leak water and cause deterioration of the roof. Whereas installing it on the ground level or window, leakage water problems can be easily managed.

If you plan to install the Evaporative Cooler on the roof or through a wall opening it is better to call a professional installer. However if you want to install it in the window, it is quite easy and you can follow the steps below to do the installation yourself.

Following are the steps to install an Evaporative Cooler in a window:

Step 1.  Choose the right location for the Evaporative Cooler

Select the window in which you plan to install the Evaporative Cooler. Check for height and width of the Evaporative Cooler and see if it will fit in the window easily. Also check whether your window is a slider, a double-hung, or a casement style. Normally the Evaporative Coolers are best installed in double-hung windows with a lower sash you can raise and lower.  Choose a window which is on the shady side of the house, so that Evaporative Cooler is not unnecessarily heated from the sun.

Step  2.  Check for electrical connection

Check that an electrical outlet is close by, if not then an extension cord will be required. Although an Evaporative Cooler does not draw as much electricity as an Air Conditioner it is best that a separate circuit with its own breaker is used to provide power to the unit.

Step 3.  Prepare the window

You should check that the window in which the Evaporative Cooler is to be installed is not damaged and strong enough to take the weight of the unit.  Installing an Evaporative Cooler in a damaged window is unsafe and a safety hazard. Remove all storm window frames and window screens and clear the area. After installation of the Evaporative Cooler, the window will not be opened or closed for a long time, so it is a good time to clean the inside and outside of the window.

Step 4.  Install Brackets (If Required)

Often Evaporative Cooler are large sized and may hang out far from the window ledge. If the window sill is not wide or strong enough, then support brackets may be needed to be installed to the outside of the window. Once installed the weight of the Evaporative Cooler can be easily balanced between the window sill and the brackets.

Step 5.  Placing the Evaporative Cooler in the window

Place the Evaporative Cooler with the help of an assistant on the window. Level it carefully. This is necessary so that water does not leak into the room.

Step 6.  Securing the unit.

After ensuring the unit is a level position, attach the chain on the edges at the back of the swamp cooler and stretch it on the side of your outer wall. Put the hooks on the outside wall and connect the chain into it. Attach the chain to the back of the Evaporative Cooler by hooking it onto the latch brackets on each side of the back of the swamp unit. The chain will hold the weight of the Evaporative Cooler and ensure that it is in a level position. If you have installed support brackets then they will take most weight of the unit and it will ensure that the unit stays in a secure level position.

Step 7.  Cover the side panels

There are accordion-style side panels. These are located on the sides and top of the unit. Expand these sliding panels so that they fill the open space in the window and screw them securely. Fix other sealing material so there is no visible opening left. If there is a gap along any seam, seal this opening with foam weather stripping that can be purchased from any local store.

Step 8.  Drain pipe

Ensure that the drain pipe is properly installed and if there is a water leakage from the unit it is drained safely outside the house.

Step 9.  Starting the unit

As per the manufacturer’s instructions; fill in the water in the unit. Connect to the electrical outlet and turn it on. Adjust air flow wanes according to your requirements. You may leave a far side window slightly open to maintain a cross flow of air across the room.
