Laguna Power Heat De-Icer

Protect the health of winter Koi with the compact Power Heat De-icer. Fully-encased unit maintains a vent hole at the pond surface for proper gas exchange. A highly visible LED pilot light indicates the unit is functioning properly, and a 15-watt heating element melts snowfall on contact to allow clear visibility of LED light. A thermostatically-controlled safety feature shuts unit down to prevent overheating if left on out of water. Safe for plastic and liner ponds, will not harm fish and plants. 22 ft electrical cord with grounded plug. 120 V, 60HZ, 315 Watt. 7" dia x 2.5" high

For climates with severe winter conditions the use of a Laguna Aeration Pump (sold separately) is strongly recommended in conjunction with the surface de-icer.

Please click on "More Information" for installation instructions.

The heated de-icer should be positioned over the deepest part of the pond.

Place the de-icer in the pond first. Then connect the cord to the electrical supply after the de-icer is properly installed in the pond water. DO NOT CONNECT THE DE-ICER TO THE ELECTRICAL SUPPLY BEFORE IT IS PLACED IN THE POND WATER. If the pond surface is already frozen do the following:

Fill a pot with boiling water, attach a cord or string to it and place it on the frozen surface. The hot pot will eventually melt a hole through the ice surface. Once a suitably large hole is created, install the unit. Never break or chop at the ice as the shock waves can unnecessarily stress pond fish.

For added stability, the de-icer can be anchored to the pond bottom using a string or cord attached to the hook underneath the de-icer and anchored to the bottom of the pond by a brick or other suitable weight.

The primary function of a heated de-icer is to maintain a small opening at the surface of the pond to allow natural degassing to occur.

For climates with severe winter conditions the use of a Laguna Aeration Pump #25415 (sold separately) is strongly recommended in conjunction with the surface de-icer.

Adding an Aeration Pump
Install the aeration pump in a suitable location as per instructions included with the aeration pump, then run the air line tubing through the hook located underneath the heated de-icer. Attach an air stone to the tubing and place at half the distance of the depth of the pond.

LED pilot light (located at the top of the de-icer)
The LED pilot light is designed to indicate when the de-icer is functioning. When the light is on, the de-icer is functioning. When the light is off, the de-icer is not functioning.

Note:
The de-icer is designed to function continuously when it is plugged in. However it has a thermostatically-controlled safety feature that will automatically turn off the heating element when the core unit reaches 34°C (93°F).
