Specifications: electrical rating: 125 volts, 15 amps, 60 hz, timed outlets 100 watt maximum per circuit. Natural Wave plugs into any 110/120 volt grounded outlet and has a 15 amp push button circuit breaker for overload protection. Instructions: Install three or more pumps in the aquarium at various locations to produce opposing currents. Outlets #1 and #3 alternate on and off so flows from these pumps should be in opposite directions. Outlet #2 follows an on/off cycle twice as long and should be directed toward suspected dead spots. Each timed circuit can handle up to 100 watts. To control the cycle period, rotate the adjustment knob from 20 seconds to three minutes. The actual cycle time can be measured by timing the indicator light and adjusting as desired. The Natural Wave pump timer should be located in a dry location, free from the risk of splash or salt spray. All electrical cords plugged into the strip should utilize a drip loop to prevent water from running into the outlet.
