The Floating De-Icer will keep a stock tank completely ice-free all winter. The thermostatic control coupled with thermal feedback protects the unit from overheating, and ensures efficient operation. The stainless steel heating element is positioned above the thermostat for safety even in low-water conditions. The float is completely enclosed in a rugged, plastic housing and will not sink over time. Recommended for 70-100 gallons of water. Note: use in a non-metallic tank requires a metal guard to prevent fire danger (metal guard, Model 88R sold separately). 6-foot cord with durable anti-rub protector. LOCKNDRY compatible. 1000 Watts, 120 Volts, 60 Hz. UL Listed, CSA Listed. One year warranty.

[instruction]INSTALLATION 1. If the unit is to be used in a non-metallic tank or pond, a Model 88R guard must be attached in order to prevent the heating element from coming in contact with the walls of the tank. The 88R guard must be purchased separately. 2. The unit should be placed in a tank or pond with water and then plugged into a Ground Fault Circuit Interrupter. 3. Some animals--particularly horses--may try to remove the 7521 and 7621 de-icers from the tank. To counteract this, you may wish to run the cord through PVC or galvanized tubing extending over the tank. Be sure to allow slack in the cord to compensate for varying water level. 4. The unit is thermostatically controlled so that it will not turn on until the temperature drops to around 40Â°F. If it is removed from the tank, it will turn on and then shuts itself off in about 60 seconds and will then cycle on and off. ATTACHING THE GUARD TO THE DE-ICER Turn the unit upside down and place the guard as shown. Rotate the short spring to thread it onto the guard and the straight section of the heating element. The spring should capture the cross-wire on the guard and be centered around the copper strap as shown. INSTRUCTIONS FOR THE LOCKNDRYÂ® CORDSET (1) Insert the plug into the receptacle just as you would a normal extension cord making sure the plug is fully inserted. (2) Slide the large nut forward to engage the threads on the plug. (3) Rotate the nut to tighten the plug against the receptacle. (4) Slide the second, thinner, red nut forward to engag
