APPLICATION AND OPERATION (CONTINUED)
3. To verify pump is operating correctly.
a. Disconnect pump from power source.
b. Connect hose adapter and discharge hose to pump.
c. Immerse pump in a bucket or tub of water at least 1-3/4
inches in depth.
d. Place the other end of the discharge hose outside the
bucket, so the water will pump out.
e. Plug power cord into a grounded 120 volt GFCI power
outlet. The pump should start after 2 seconds of
detecting water. Once the pump removes the water to a
depth of 3/8 inch, the pump will stop automatically.
f. If pump does NOT operate, unplug power cord and
proceed to maintenance – step 5.
4. To verify discharge hose is free from a blockage.
a. Connect hose to another water source such as a faucet.
If water flows through hose, return to step 3a. If water is
restricted, verify discharge hose is unwound. Remove all
kinks, bends, or obstructions in hose.
b. If pump is still NOT operating, proceed to step 6.
5. Periodic cleaning of pump is required to maintain
performance of the pump. Follow the cleaning steps listed
below:
a. Unplug the power cord.
b. Remove the four (4) base screws (Figure 2).
c. Remove the base and impeller plate.
d. Remove the debris and make sure the impeller turns
freely.
e. Reinstall impeller plate, base, and screws.
6. Check the priming hole for obstruction. (Figure 2).
Follow the cleaning steps listed below:
a. Unplug the power cord.
b. Remove the four (4) base screws (Figure 2).
c. Remove the base and impeller plate.
d. Use a pin or paperclip to clean the priming hole and air
escape channel.
e. Reinstall impeller plate, base and screws.
3. For best pump performance, unwind the hose before starting
the pump. This will help remove any kinks or binds in the
hose and allow the unit to pump with less restriction.
4. Set the pump on a hard, flat surface in the water. Do not set
the pump directly on mud or sand surfaces. This will cause
the inlet screen to clog.
5. The water level must be at least 1-3/4 inches for the pump
to cycle, prime, and operate. Water levels less than 1-3/4
inches will not allow the impeller to contact water therefore
no water will be pumped.
Do
NOT handle pump with wet
hands or when standing in water
or on a damp surface when the unit is operating or fails to
operate. ALWAYS disconnect pump power cord from
power source before handling.
6. Plug the pump into a 120 volt GFCI protected outlet. The
pump will start automatically when the water reaches a depth
of 1-3/4 inches. A priming delay of 2 seconds is programmed
into the control to allow time for air to escape from the
pumping chamber.
7. The pump will stop automatically once water has been
removed to a depth of approximately 3/8 of an inch above
the hard surface. The pump will not restart until the water
depth rises to 1-3/4 inches or greater.
8. The pump will not allow itself to run dry. Once the pump
detects that water is no longer being removed, it will shut down
automatically. The pump must remain upright at all times in
order for the water detection to function. The shaft seal depends
on water for lubrication. Do not allow the pump to operate on its
side or inverted.
Do NOT alter the pump to override the automatic
water detector. The shaft seal depends on water
for lubrication. Overriding this pump feature can cause the pump to run
dry and may damage the shaft seal and cause pump failure.
MAINTENANCE AND TROUBLESHOOTING
Pump starts automatically.
Always disconnect electric supply
before attempting to install, service, relocate, or
perform any maintenance. Failure to do so could result
in fatal electrical shock.
Minimal service is required for this pump. The motor housing of
the pump is completely sealed and requires no service. If pump
should fail to operate, perform the following troubleshooting
guidelines:
1. Verify pumping height does NOT exceed 13 feet (See Figure
1). If pumping height is greater than 13 feet, this pump will
NOT operate.
2. Verify water depth is 1-3/4 inches or greater (See Figure 1).
Do NOT disassemble or alter this
product in any way. Failure to
follow these instructions will result in serious injury or
death.
