How to Wire a Swamp Cooler How to Wire a Swamp Cooler

What You'll Need
No. 2 Romex cable
screwdriver
wire pliers
wire stripper
plastic wire nuts
circuit breaker with the same amperage as the cooler

The swamp cooler is an excellent device to cool down and moisturize your living area, especially if you live in a dry and hot climate. The way the cooler works is pretty simple, but very efficient: ambient air gets sucked into the unit where it is cooled down through evaporation and released back into the environment. The appliance can be used to condition air both inside and outside the house, depending on your requirements. If you have just bought a swamp cooler and want to install it, you should keep in mind that the way you wire it will depend on the electric requirements for the unit’s water pump and air circulation fan. Here are the steps you should follow in order to install the swamp cooler.

Step 1–Check Local Requirements

Go through the local requirements for the wiring of electrical devices. In some states, you may be asked to mount a residual current device to insure the cooler’s safe operation. Do not forget to read the manufacturer’s instructions. Due to warranty-related issues, some companies insist that a professional electrician does the installation. Regardless of what your case may be, make sure that you are well-acquainted with all pertinent requirements and regulations.

Step 2–Run Romex Cable

Take the Romex cable and guide it from the electric makeup box of the swamp cooler to the electric panel box with the breakers. If there is a hole blank in the panel, remove it with the screwdriver and/or the pliers. Then, plug the box connector in the hole. Fix the connecting nuts with the wire pliers.

Step 3–Remove Insulation

Remove with the wire stripper six inches off the insulation on both ends of the Romex cable. Lay the cable ends inside the box connector and fix the cable by tightening the cable clamp.

Step 4–Connect Wires

Strip one inch off the black and white wires of the cooler’s electric box using the pliers. Connect the black wire of the cable to the black wire of the cooler by splicing them together and protect the connection with a plastic nut. Repeat the procedure for the white wires. Then, connect the ground wire to the appropriate screw on the cooler’s electric box and fix tight with the screwdriver.

Step 5–Install Circuit Breaker

Mount a circuit breaker on the electric panel, whose amperage rating is the same as that of the cooler (if necessary, refer to the manufacturer’s instructions for the cooling unit). Before you insert the breaker into the bus bar, check that it is turned off.

Step 6–Attach Wires to Bus Bar and Circuit Breaker

 Attach the ground and white wires to the bus bar located at the back of the panel box. Connect the black wire to the terminal on the circuit breaker and tighten up well to secure the connection. Turn on the circuit breaker and ascertain that the cooler operates properly.
