What safety precautions should I follow when operating the Coolmate 4?

Only qualified persons should install, operate, maintain, and repair this unit. Keep everybody, especially children, away during operation. Hot parts can cause burns—do not touch bare-handed and allow a cooling period before working on the equipment. Coolant is under high pressure and can injure or kill—release pressure before working on the cooler. Visually inspect hose condition before each use and do not use damaged hoses. Keep all doors, panels, covers, and guards closed and securely in place.
