The white wires or neutral connect to the common junction point on the water pump and the white connection point on the switch. The other end of the black wire is connected to the switch. On the cooler side, the black wire connects to the blower motor via a junction.

Yellow – this wire runs the water pump.

White – functions as the common wire or neutral.

Red – low wire for the Low power setting.

Black – hot wire for the High-power setting.

In terms of wiring colors, the swamp cooler will have five colors in total. The blower will have connections for high, common, and low, labeled as H, C, and L. The blower will usually have two speeds for low and the high performance. The blower, on the other hand can be run by the similar 110/120 AC connection or it can run on a 220/230-volt AC connection. The water pump runs on a 110/120-volt AC connection which needs to be plugged into a wall socket or similar connection to run. The wiring is used to run two different aspects of the cooler, the blower as well as the pump that moves the water through the unit for the cooling effect. That’s because there is some variation from one product to the next, depending on the brand and model.

So just get extra and trim it as needed.Īlways check your swamp cooler model and instructions first before getting started. Plus, cable strung too tight can pull free over time, which will be annoying and a frustration as well.

It’s better to get extra cable to start with and size down from there than to be too short have to start all over again finding out the hard way. If, on the other hand, one is dealing with a twin-speed motor, then the cable needs to be a five-conductor type. If the first category, then the cable needs to be a four-conductor format to work right. This cable, known as a multi-conductor, works for either a single-speed motor or a twin-speed version. The first part is figuring out which cable needs to be used with the motor in the given swamp cooler. Instead, one might simply want to go a step further and just have activation with a wall switch. However, most homeowners aren’t dealing with these challenges. On the other hand, if one has a commercial or industrial evaporative cooler, then dedicated wiring will be needed. They definitely don’t need a dedicated power supply or a specialized plug system like a washing machine, for example. These units are designed to work off of basic, simple power supply that one can find in just about any home and wall plug unit. In most cases, when people have room swamp cooler put in place and installed, powering the unit is a simple matter of finding the nearest wall plug and connecting it.
