Self-contained heated eyewash and/or drench hose. Delivers over ten gallons (37.9 liters) of water for 15 minutes. Heated and insulated to endure sustained low or freezing temperatures over long periods of time. Fully freeze-resistant, and tempered, for both indoor and outdoor environments. Ideal for low traffic areas, where installation of plumbed equipment is not cost effective. To operate unit, fill with clean potable water and add bacteriostatic additive (supplied with unit). Additive protects against growth of bacteria, fungus, algae and acanthamoeba inside unit. After filling with water, pressurize unit to 80 PSI air pressure. If necessary, adjust pressure regulator to achieve maximum flow for 15 minutes. Unit should be inspected regularly and water in unit should be changed at least once every six months.
