Product Installation

Installation of the Giant Fountain will require partial assembly of the unit and the services of a certified electrician. Tools and materials required can include: a shovel (to bury/trench cable,) conduit, stainless steel cables, boat, crane (depending on landscaping), rebar or duckbill anchors, 1/2in ratchet wrench, 9/16in wrench and socket set. Complete installation instructions will be provided with the delivery of the product.
To receive a Giant Fountain the facility should be equipped with a loading dock and fork lift. Average weight of shipment will range between 900-950lbs or 410-435kg.

Basic Installation Guidelines:

Unit Assembly: Unit will be shipped partially assembled with only minor assembly required for float assembly and mounting float to unit. Depending on horsepower and pattern selection some additional assembly may be required. While typical packaging has the unit crated, it may arrive in several cartons depending on options selected and cable lengths. All hardware is provided. Estimated time to assemble unit is 3 hours.

PCC Installation: Qualified electrician will need to be on-site to install power control center (PCC is standard for all domestic/60Hz applications.)

Power Cable: Power cable should be buried or trenched in conduit per local codes, and run at least 3ft or 1m out into the pond/basin. If a cable quick-disconnect is not ordered with the Giant Fountain, electrician/installer will be required to splice cable to unit.

Launch Unit into Water: With the four rugged polyethylene wheels attached to the frame, the Giant Fountain can be rolled or wrenched along the ground and launched into the water. Using a boat launch or manmade ramp can ease this process. While a crane or hoist can simplify the installation process, many successful installations and retrievals have been done using a ramp/truck/liftgate method. Ponds with steep banks will require a crane.

Adjust Flotation: Various float sections have marine plugs that allow you to adjust buoyancy and float level if necessary.

Secure into Place: The unit features a 3-point mooring system with eye bolts provided on the frame. Otterbine recommends the use of 3/16in diameter stainless steel cables for mooring lines. Mooring the unit can often be done from the shoreline, but a boat will assist in the process.

Allow 4-6 hours, with a two to three man crew to install, set the unit in the water and adjust buoyancy.


Otterbine offers an exceptional two year warranty on the Giant Fountain line, but can be extended to three years with the purchase of the Sub-Monitor motor control option. This warranty extends to the complete package including the unit, cable and power control center.

Warranty and service work can be performed by more than 100 factory trained and certified Otterbine Service Centers found worldwide, or by Otterbine directly. A copy of the warranty statement for this product can be found within the Installation Manual.


No routine maintenance is required. Unit maintenance is very simple as the motor is a high speed water lubricated motor and there will be no need to change oil or for annual maintenance. When the screen becomes clogged it will be necessary to clean it and can be cleaned with a wire bristle brush. All units have a basket type screen that can be easily removed and cleaned while the fountain is in place.


Giant Fountains must be removed in climates that experience cold winters and frozen waters before lakes freeze over. The motor and pump must be stored in a heated area that stays above 32° Fahrenheit or 0° Celsius.
