WARNING

Read all instructions carefully before installing and using this product.
To prevent personal injury, disconnect the power source when installing
or servicing this product. Always remove the boat from the water before
using 120V AC power tools.
DO NOT use pump to remove gasoline, oil or other flammable liquids.
Always use the fuse amperage rating specified for your pump model.
Failure to do so could result in serious personal injury or fire hazards.
Attwood bilge pumps are designed to exhaust STANDING WATER
ONLY. They are not intended to prevent rapid accumulation of
on-board water due to rough weather, hull damage, and/or other
unsafe navigational conditions.
Refer to Specification Chart to be sure you have selected the
proper pump:

2. Do not mount pump directly to hull. Attach base strainer to a
marine plywood mounting pad that is fiberglassed to the hull.

HOSE CONNECTION INSTRUCTIONS

IMPORTANT: To prevent airlock, hose must rise continually upward
to the thru-hull connector with no dips or sharp bends. Support hose
if necessary.
1. Orient pump outlet for a direct, unobstructed hose path.
2. Secure all connections with hose clamps.
3. If no thru-hull connector exists, install at 12" min. (25mm) above
water line. Apply marine sealant around thru-hull flanges on
interior and exterior of hull.

PUMP MOUNTING INSTRUCTIONS

1. To access mounting holes, remove base strainer. Hold housing with
one hand, depress locking tab with other. Twist counter-clockwise
and remove pump housing from base. It is not necessary to remove
motor cartridge for installation. (Figure 2)

CAUTION: Do not drill through hull. Before drilling be sure mounted
pump will be correctly positioned with pump nozzle pointing toward
thru-hull connector. (Figure 1)
3. Remove base. Drill three 1/8" (3mm) pilot holes at marked locations.
4. Replace base. Attach with #8 stainless steel fasteners.
5. Re-attach pump to base. Insert into base, twist clockwise until tab
snaps in and prevents turning. (Figure 2)

WIRING INSTRUCTIONS

Make all wire connections above the highest water level. Use marine
grade wire connectors only. Waterproof all connections with suitable
materials. (Figure 3)
NOTE: Failure to make waterproof connections and fuse pump properly
will void the product warranty.
