Sea Frost DC 5000 installation instructions About The Pump, Plate Location

Install the intake through hull as low in the boat as possible. The minimum size through hull should be 1/2". In areas of floating weed and jelly fish a larger through hull might be beneficial. The sea strainer should be positioned above the through hull with no loops of hose that could trap air. The pump should be positioned above the strainer and pump up to the DC 5000. The water hose from the DC 5000 should leave the condenser and descend or remain parallel to the water line exiting a through hull above the water line.

ABOUT THE PUMP

The March 809 BR pumps are not self-priming. The coupling between the impeller and the motor is through a pair of magnets. The impeller is water lubricated and does not touch the housing in proper operation. The advantage of this pump is a long life, quiet operation and low power consumption. To treat this pump properly it must be flooded at all times. Air pockets created by rising and falling hose levels and an improperly located pump and strainer will trap air, which the pump will not be able to displace preventing water pumping. The only acceptable installation will not have air pockets in the water circuit.

PLATE LOCATION

The plate size, location, and plumbing are designed for each application. This information is provided with each system.

SEA FROST holdover plates mount with a "Wellnut" expandable neoprene blind hole fastener. A template or the plate itself should be used to locate the mounting holes. Drill 1/4" pilot holes then increase them to 1/2". Install the screw into the mounting tab then screw the Wellnut onto the screw. Install the plate pushing the rubber mounts into the pre-drilled holes. Tighten the screws.
