Product Description The 4' x 8' Ice Equalizer Pillow relieves stress from the walls of your pool caused by ice. Ice Equalizer pillows also reduce the build-up of rain water, leaves and snow on your winter cover. All you have to do is inflate the pillow and place it under your cover during the winter months. Do not overfill the pillow with air, as this can cause the valve to pop out during the winter months. Safety Warning Always follow the manufacturer's instructions for proper installation, use, and maintenance. Keep children and pets away from the pool area when the cover is in use. Do not allow anyone to walk on the cover. Store the cover in a dry, well-ventilated area away from direct sunlight and heat sources when not in use.
