MAINTENANCE
DISPOSAL
The motor unit is hermetically sealed by high quality resin and does not require any care. The
impeller assembly rests inside an easy-open cover to allow occasional spot checks for grime and dirt.
The water chamber has an effective self-cleaning feature, but regular maintenance will lengthen the
life of the impeller and motor unit. To do maintenance cleaning, open the clips at the two sides of
the water inlet cover, and remove it and the water chamber cover from the pump.
Please note that soaps and detergents are not recommended for pump maintenance because their
residues can be toxic to plants and fish.
Do not dispose of this unit with domestic waste! For
disposal purposes, please use the return system provided.
Disable the unit beforehand by cutting off the cables.
Installation when used inline:
1. Remove the water inlet cover by first removing the bottom screw, then by prying the two green
tabs rearward with a large flathead screwdriver. Now remove the sponge filter.
2. Allow some water to flow into the pump's water chamber.
3. Note that the multi-angle connector allows you to choose from many different connection
angles simply by loosening the large central ring nut, selecting your desired angle, then
tightening it again. Set your desired connection angle before attaching it to the pump.
4. Screw the multi-angle connector onto the water inlet, which is the horizontal male threaded
1.0" fitting which faces into the water inlet cover. Attach your incoming 1.0" pipe, using a female
threaded 1.0" fitting, to the multi-angle connector.
5. Now screw the tubing adapter to the pump's outlet (the vertical male threaded 1½" fitting
which faces straight up). The tubing diameters compatible with the adapter are 1.0" and 1.25"
(model AAPC2010) and 1.0" and 1.25" (model AAPC2020). Using a common hose clamp, secure
your outflow tubing to the adapter. The pump is now ready for use.
TROUBLESHOOTING
SYMPTOM
CAUSE
REMEDY
The pump doesn't run
Power is not turned on
Turn on the power
Pump is not plugged in sufficiently
Plug in sufficiently
Impeller is binding
Remove foreign matter from impeller
The motor cycles on and off
immediately without the pump
running or the motor suddenly
stops and can’t be started again
Wrong voltage is being used
Apply correct voltage
The water inlet or outlet pipe is
clogged with foreign matter
Remove foreign matter
The pump runs normally at
the beginning, but then water
flows out sluggishly or stops
flowing completely
Impeller is worn out
Replace impeller
Water level goes down too far and
the pump is exposed
Increase water level
Hose is too long or is clogged with
foreign matter
Shorten the hose or clean it out
(During inline use) There is air in
the impeller chamber (”air-lock”)
Unplug pump. Submerge pump, disconnect the inlet fitting,
and turn power on. This will prime the pump's internal
components and release the trapped air. Reconnect the
inlet fitting, remove the pump from the water, and plug it
in again.
