the pump suction port). Slide each hose on the respective port of the pump.
Secure with the hose clips.
5. Run the discharge hose upward, towards the hull's thru-fitting for the water
discharge. The discharge thru-fitting should be installed at least 30 cm above
the water line to prevent backflow when the pump is not in operation (see Fig.
1 and 3).
6. Avoid downward bends in the discharge hose or water can stagnate, resulting
in air clogging of the pump. Avoid extreme stress and straining of the discharge
hose or the discharge port stub may fail.
7. Connect the discharge hose to the thru-fitting and secure the connection using
a hose clip.
8. The product is now ready for use.
HOSES:
1. For the discharge hose, use a hose with internal reinforcement and the
compatible I.D.
2. Install the hose to achieve the lowest head dowstream of the pump's discharge
side.
3. To prevent the backflow of water when the hull rolls or heaves, it is
recommended to make an S-bend at the highest point of the discharge hose
(which should be above the water line (see Fig. 1 and 3).
4. Routinely inspect the suction hose for heavy dirt and clean it as required.
5. When installing the pump in the bilge and installing the suction and discharge
hoses, avoid kinks and keep the maximum possible bending radii.
6. Do not install a check valve in any hose.
CAUTION! If the discharge hose is common to an electric bilge pump
(Fig. 4 item B), install a check valve between the electric bilge pump's
discharge side and its tie-in of the manual bilge pump's discharge hose.
7. Thread the hoses onto the pump ports to secure. Secure the hose connections
with hose clips tightened over the port stubs.
8. The hose shall be installed horizontally or with an uninterrupted slope upward
away from the pump to eliminate air pockets.
9. Always make sure that the nozzle is properly installed in the appliance and the
hose is properly attached and free of damage before use.
