Rules of Safety
- Disconnect electrical power at the fuse or breaker box and remove the motor and pump plug from the junction box before you begin installation or servicing your cooler.

- Wear rubber-soled shoes when working on the roof of your house.
- Make sure the mounting surface on your roof will support the weight of your cooler.
- Don’t install or service your cooler during rain or high wind weather conditions.
- Keep your children a safe distance from where you are working.
- If you work with power tools, wear protective eyewear and gloves.
- Have adequate means to raise the cooler to the roof to prevent damage to the cooler and injury to yourself. Removing the pad frames from the cooler prior to raising it to the roof can make the job much easier.
- Never drain your cooler onto the roof. Use a hose connected to the drain fitting to drain the water off the roof. Water residue could stain your roof or cause you to slip.
- Always use the right tools.
