7. Connect the motor lead wires as indicated in Table I
and as shown in Figure 1.
NOTICE:
In order for the pump to run in the proper
direction, the wires must be connected correctly.
8. Power Supply: Pump is designed for use with a 12
Volt DC battery. Operation requires a minimum 12
Volt power supply.
OPERATION
Risk of electric shock. Do not handle a
pump or pump motor with wet hands or when standing
on wet or damp surface, or in water.
Risk of Fire and Explosion. Can cause
severe injury, property damage or death.
Do not use in
explosive atmospheres. Pump water only with this pump.
1. The shaft seal depends on water for lubrication and
cooling. Do not operate the pump unless it is pump-
ing water. The seal will be damaged if the pump is
allowed to run dry. Add one tablespoon of liquid
cooking oil to both of the threaded ports before each
use. Do this before starting the pump.
NOTICE:
DO NOT run this pump dry. Running this
pump dry will void the warranty.
2. The pump motor requires a fully charged 12V DC
battery for operation.
Risk of electric shock. Can burn or kill.
Before attempting to check why a unit has stopped
operating, disconnect the battery from the unit.
3. Make sure that all of the suction connections are air
tight. Most priming problems are due to air leaks in
the suction line.
4. If the pump does not prime itself in one minute, dis-
connect the pump from the battery and refer to the
troubleshooting section on Page 5.
MAINTENANCE
1. Replace the impeller and cam ring every 250 hours
of use.
NOTICE:
Severe or abrasive use can wear out the
cam ring quickly. Grass, mud, sand or pea gravel can
cause abrasive wear. Keep the pump inlet clear.
2. When you have finished pumping, disconnect the
wires from the power source to be sure the unit is
turned off.
IMPELLER REPLACEMENT:
For impeller replacement refer to Figure 2.
1. Loosen and remove the cover screws.
2. Remove the cover plate and the O-Ring.
3. Remove the outer wear plate.
4. Remove the old impeller and cam ring and discard
them.
5. Examine the inner wear plate for wear. If it is worn,
remove it, turn it over and reinstall it.
6. Grease the outside diameter of the new cam ring and
install it.
7. Put a small amount of grease on the inside diameter
of the cam ring and on the surface of the wearplate.
