MOUNTING
 Locate the pump in the deepest position in the bilge. Keep
away from high heat source.
 Mount quick disconnect bracket to bulkhead or stringer with
#10 S.S. screws. Do not drive screws through hull.
 Route smooth I.D. discharge tubing to a thru-hull fi tting
well above the water line. Avoid any sagging or loops in the
tubing. Tubing must go up from the pump to the thru-hull
fitting.
ELECTRICAL
Use 16GA wire for all circuits. If installation is over 20 feet, use
14GA wire. Brown pump wire must be hooked to positive power
for maximum flow. Wire is tinned to prevent corrosion.
PANEL SWITCH
Attach all wires to UL Marine approved duty switch with auto-
off-manual, rated at or above 15 amps.
FUSE
Install a fuse per pump label specifi cations.
CONNECTIONS
Wire connections should be made above the highest possible
water level. Seal wire connections to prevent corrosion and
electrolysis.
OPERATION
Do not run pump dry. Always test pump and switch before leaving
dock.
MANUAL MODE
To turn pump on, turn manual power switch on. If pump does not
turn on, turn switch off, check power, fuses, connections, wires.
Retry. If pump does not turn on, check pump motor.
