Sea Frost DC 5000 ユーザーズマニュアル
12
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.
