Winterize Your Cooler

Protect your investment from freezing temperatures. Follow this 15-minute guide to prevent costly pipe bursts and rust damage.

Turn Off Water Supply

Locate the water shut-off valve (usually sending water up to the roof) and turn it completely off. This is the most critical step to prevent frozen pipes.

Tip: If your valve is stuck, do not force it. You might need a plumber to replace it.

Drain the Tank & Line

Go up to the cooler and remove the overflow standpipe (the tall tube in the drain) or open the drain plug. Let all water drain out of the pan.

✓ Disconnect the water supply line from the cooler fitting to let it drain completely.
✓ Use a sponge to soak up any remaining water in the bottom of the pan to prevent rust.

Disconnect Power

Unplug the unit from the receptacle inside the cooler (if equipped) or switch off the dedicated breaker at your electrical panel. This prevents accidental startup during winter.

Install Cover & Damper

Slide the damper (metal sheet) into the slot between the blower and the duct to stop heat loss from your home. Finally, install a heavy-duty canvas or vinyl cover over the entire unit.

Why cover? It prevents rust, keeps dust out, and stops cold drafts from entering your home.
