Wiring Instructions - Xylem rule DB412 Instruction Manual

Electrical
Disconnect power before installing or servicing the pump.
All potential sources of ignition located in spaces containing gasoline
powered machinery or gasoline fuel tank(s), or joint fitting(s), or other
connection(s), between components of a gasoline system, shall be
ignition protected in accordance with the requirements of ISO 10133,
ABYC E-11, AC and DC Electrical Systems On Boats.
The electrical wiring, connections, and installation shall be in accordance
with the requirements of ISO 10133, ABYC E-11, AC and DC Electrical
Systems On Boats.
CAUTION:

damage to the unit.
CAUTION:
should a short occur. Failure to install proper fuse could increase risk of pump
malfunction potentially resulting in personal injury and/or fire hazard.
CAUTION:
must be joined with butt connectors and a marine grade sealant to prevent
wire corrosion.

Wiring Instructions

• Make all electrical connections in dry locations; connections in humid
environments should be sealed to prevent corrosion.
• Protect the circuit with a rated fuse or circuit breaker in the red
positive (+) lead as close as possible to the power source.
• Connect the black motor wire to the negative (—) battery terminal.
• Inadequate voltage at the motor terminals when the pump is running
(not less than 10% below rated voltage at full load) due to partially
discharged batteries or insufficient cable size may result in blowing
fuses, failure to start or poor pump performance.
• Ensure sterilization of wet end before disassembly.

WARNING:
fuse terminals with silver paper or metal wire. Failure to observe this instruction
may result in a fire hazard due to overheating of cables.
Plumbing
Factors that reduce the flow of a bilge pump may include but are not
limited to the following:
• The length of discharge piping (longer runs reduce flow)
• The number or radius of bends
• Excess amount of debris in water. A strainer or other means of
preventing debris from entering the pump inlet should be used to
prolong life and performance.
• The roughness of the interior surfaces of piping and fittings (smooth
bore hose is best)
• The reduction (hose restriction) in cross-sectional area of discharge
system components such as check valves and thru-hulls
The discharge may be located below the maximum heeled waterline if the
discharge line is provided with both of the following:
