How-to Guide to Prepare Your Swamp Cooler for Winter
- Cut off Power Supply
Before doing anything else, it is important to disconnect the power supply to avoid electrocution. Unplug the unit and roll up the power cord.
Disconnecting it from the power supply will also ensure that the unit doesn’t accidentally turn on during the winter months.
- Turn Off Water Valve/Supply
It is important to drain the water line from your swamp cooler to prevent water from freezing during winter. You can find the water valve by tracing the waterline all the way to the source.
Once you find it, shut the valve and disconnect the waterline. It is likely that excess water will remain in the waterline after you shut the valve.
What you can do is blow through the pipe/line to remove any excess water. Because in the winter months any remaining excess water in the waterline can turn to ice, expand, and eventually burst the waterline.
Hence, what we want are pipes that are free of any excess water to prevent such damage. Better yet, if you are able to remove the water line altogether, you can do so. You can then coil it up and store it where it wouldn’t freeze.
- Drain the Cooler
No water should be left in the cooler otherwise it will accumulate on the metal parts and induce rust. Both sides of the cooler must be drained and wiped off.
After that, make sure to clean the area and use the sponge with the bucket to absorb any excess water.
The pan needs to be drained during fall and must remain open to let rainwater pass through it. It should be able to that all throughout winter, otherwise, the pans will rust.
Once cleaned, some dirt and debris may still remain. Use a hosepipe to remove any excess dirt from the pan. After that wipe it down and pat the area with rags until dry.
- Clean the Cooler on the Inside
Clean the inside walls of the cooler. Clear away any dirt and grime that may have accumulated throughout summer. If you clean it before winter no need to huff and puff reusing it by spring.
- Change the Evaporative Pads
Most owners would think about changing the pads in spring when the cooler is once again ready for use. With the way the louvers are positioned, they are specifically designed for rainwater to flow into the pads, which in turn the pads themselves are pressed up against the louver.
This can cause accelerated rusting on the louver which necessitates the need to install new evaporative pads. Replacing the pads before winter can prevent severe rusting all throughout the cold months
- Use a Cover
Upon completion of the draining and cleaning process, you will need to make sure that your unit is covered throughout the cold months. The cover should be waterproof and big enough to accommodate the actual size of your cooler.
This should keep put both dirt and dust from getting into the cooler while in storage. Ultimately, a durable cover will keep your cooler clean and ready as soon as spring breaks.
- Cover Your Ventilation Shafts
The purpose of these vents is to circulate cool air into the house during summertime. Since you wouldn’t want to have freezing cold air come into your house during the winter months, you will have to shut down your vents.
Cover them too with material that can create more insulation. This will ensure that your house will not suffer heat loss and remain warm throughout the cold weather months.
Frequently Asked Questions
How often do I replace the cooling pads?
It depends on the frequency of the cleaning. If you clean your machine on a regular basis, then you won’t have to change them as much. Always inspect the pads prior to using your cooler after a long storage period.
If you see any cracks on the pads, then you will have to have them replaced immediately.
What is the best time for me to winterize my swamp cooler?
You can start winterizing your cooler during late fall, which is just in time before the winter sets in. By the time its over, your cooler will be immediately available.
