If these pumps are being used in salt water,
they must be checked regularly for buildup of
calcium and other deposits.
To maximise the life of your pump, it is
recommended to clean the pump casing and
the impeller every 6-8 weeks or earlier if flow
has decreased significantly.
Prior to cleaning, disconnect the pump from the
electrical power supply.
The casing of the pump and the strainer can be
cleaned with a firm brush. DO NOT USE
DETERGENTS AS THE USE OF THESE WILL
BE POTENTIALLY LETHAL TO AQUARIUM
INHABITANTS. Any objects on or around the
strainer or inlet should be removed to prevent
potential blockages in the pump or damage to
the impeller.
LOW WATER FLOW
1. Check strainer, impeller and impeller
chamber for calcium buildup or other deposits
or blockages.
2. Ensure all taps or flow control valves are fully
open.
3. Clean plumbing lines to and from the pump.
NO WATER FLOW
1. Ensure all taps or flow control valves are fully
open.
2. Check that maximum head height has no
been exceeded. Consider all bends and
horizontal plumbing when calculating head
height.
3. Check impeller and shaft for damage.
PUMP IS NOISY
1. Ensure suction cups are correctly positioned.
2. Check for blockages on the pump inlet.
Restriction of inlet can cause vibration.
3. Check for damage to impeller or shaft.
Before installation ensure the correct materials
have been prepared and the most suitable
pump position has been selected. As with all
water pumps, the greatest flow efficiency will be
created through the shortest length of
pipe/hose and with the fewest number of
bends. Avoid reducing the size of the plumbing
as this will greatly reduce flow.
Note: flow is reduced less through 2 x 45°
bends than through a single 90° bend.
Flexible hose is recommended over rigid pipe
as this will reduce vibration of the pump. If using
rigid plumbing, a short piece of flexible hose
between the pump and the pipes will help to
reduce vibration.
If there is a requirement to adjust the flow on
your pump, it is essential that in-line taps are
used only on the pressure (outlet) side of the
pump. Restriction of the suction (inlet) side of
the pump can cause the motor to overheat
causing damage to the pump.
It is recommended that the strainer is used to
prevent fish or large objects from entering the
motor unit and damaging the impeller. Ensure
the pump is fully submersed to prevent air from
entering the pump which can result in
significant loss of flow and potentially cause
damage to the motor.
If the pump is being used in a clean, animal free
environment the inlet elbow can be used. This
gives the pump the ability to pick up water from
a lower point reducing the risk of the pump
running dry.
NOTE:
it is always recommended
that the pump be fully immersed in water to
avoid the unit overheating.
