hazards
• Always bear in mind the risk of drowning, electrical accidents and burn injuries
User safety
DANGER: This product is not intended for damage control or to deal with ŷooding
resulting from hull damage. This product is intended to be used in Bilge Pumping
Systems for small craft with a hull length up to 24 meters, as described within the intro-
duction and scope of -S3. Bilge Pumping Systems, as speciŶed in -S3,
are limited to normal amounts of water in an intact boat due to spray, rain, seepage,
spillage, and occasional small amounts of water shipped from boat movements in
heavy weather. 9se of product in any other way could result in ŷooding, catastrophic
damage to craft, serious personal injury, or death.
WARNING: This pump is designed for use with fresh water and salt water ONLY. Use
with any other hazardous, caustic, or corrosive material could result in damage to the
pump and the surrounding environment, possible exposure to hazardous substances
and injury.

The following is a summary of typical wiring installations:
Disconnect power before installing or servicing the pump.
Our pump is equipped with silicone blocked, tin coated 16 gauge wire. Please follow the table below when extending
the wires.
This pump must be fused with a 7.5 amp fuse (not included).
All potential sources of ignition located in spaces containing gasoline powered machinery or gasoline fuel tank(s), or joint
Ŷtting(s),or other connection(s),between components of a gasoline system, shall be ignition protected in accordance with
the requirements of ABYC E-11,AC and DC Electrical Systems On Boats.
The electrical wiring, connections, and installation shall be in accordance with the requirements of ABYC E-11, AC and DC
Electrical Systems On Boats.

Bilge pumps shall be mounted in accordance with the pump manufacturer instructions, and in an accessible location to
permit servicing and cleaning of the intake and/or screening.
On boats with an enclosed accommodation compartment, an audible alarm shall be installed indicting that the bilge water
is approaching the maximum bilge water level.
Bulkhead penetrations shall be in accordance with the requirements of ABYC H-2, Ventilation of Boats Using Gasoline, to
minimize the potential for migration of carbon monoxide from machinery compartments containing gasoline engines to
adjacent accommodation compartments.
Potential electrical sources of ignition located in spaces containing gasoline powered machinery, or gasoline fuel tank(s),
or joint Ŷtting(s), or other connection(s) between components of a gasoline system, shall be ignition protected,unless the
component is isolated from a gasoline fuel source as described in ABYC E-11.5.3.3
Exception:
1. Boats using diesel fuel as the only fuel source.
2. Outboard engines mounted externally or in compartments open to the atmosphere in accordance with the
requirements of ABYC H-2,Ventilation of Boats Using Gasoline.
The bilge pump inlet shall be located so that excess bilge water can be removed from the bilge at static ŷoating position,
and at maximum conditions created by the boat’s motion, heel, and trim.

Installation:
We recommend using #8 Stainless Steel screws of an adequate length as to secure the pump but not penetrate the entire
thickness of the hull. Use a ŷexible sealant in the screw holes to prevent water from penetrating the screw holes.

Best practice: Use two stainless
steel hose clamps to attach hose to
hose barb.
During the winterization of a vessel, it’s recommended that you remove the check valve (if equipped) and drain any residual
water from the plumbing.
Plumbing:
This bilge pump has been designed to be used with ŷexible hose. Rigid piping or tubing may damage the pump or the pump’s
discharge.
*actors that reduce the ŷow of a bilge pump may include but are not limited to the following:
• The length of discharge piping (longer runs reduce ŷow)
• The number or radius of bends
• The roughness of the interior surfaces of piping and Ŷttings (smooth bore hose is best)
• The reduction (hose restriction) in cross-sectional area of discharge system components such as check valves and
thru-hulls
Attach the discharge hose to the hose barb using stainless steel hose clamps.
The thru-hull discharge Ŷtting should be mounted at least 8ŕ(2.3 cm) above the heeled water line to prevent water
siphoning in from outside the vessel or the discharge may be located below the maximum heeled waterline if the
discharge line is provided with both of the following:
• A seacock installed in accordance with the requirements of ABYC H-27, Seacocks, Thru-Hull Connections, and
Drain Plugs, and
• A vented loop or other means to prevent siphoning into the boat.A check valve shall not be used for this purpose.
-f the discharges of several pumps are manifolded to discharge through a single thru-hull Ŷtting, the system shall be
designed so that the operation of one pump will not back feed another pump, and the simultaneous operation of each
pump will not diminish the pumping capacity of the system. A check valve shall not be used in the discharge manifold
system.
A check valve may be used only when necessary to prevent an automatic bilge pump from cycling on and off due to back
ŷow from the discharge line.
Hose connections shall be secured with a non-corrosive type of clamp, or be mechanically fastened with permanently
attached end Ŷttings, such as swaged sleeve.Threaded inserts shall be attached with corrosion resistant metallic clamps.
Please note that the check valve should NOT be used
with the elbow Ŷtting. The check valve and elbow
combination greatly restrict the ŷow.
