Installation

WARNING
Risk of electric shock – This pump is supplied with a grounding conductor and grounding-type attachment plug. To reduce the risk of electric shock, be certain that it is connected only to a properly grounded, grounding-type receptacle.

Important:

Always place the unit below water level.
It is recommened to place the unit horizontally on the ground ensuring its stable position.
Do not lift the pump by its power cord. Use the handle to lift and maneuver the pump.

For maximum water flow, it is recommended that the largest tubing size for your pump is used.
○ If needed, cut the adapter as shown using a hacksaw; consult packaging for tubing size.
Attach the adapter to the pump first, then connect tubing to the adapter.
NOTE: Tubing is NOT INCLUDED.
Attach the other end of the tubing to desired water feature or spillway.

Start-up

Attention! The pump must never run dry.
Possible consequences: The pump will be destroyed.
Protective measures: Check the water level at regular intervals. Always place the unit below water level.
Attention! The installed temperature sensor automatically turns the pump off, if it is overloaded. The pump automatically switches on again once the motor has cooled down . Risk of accident!
Install the unit so that it is not exposed to direct sun radiation (max. 104 ºF – 40 ºC).

Important:

The unit switches on automatically when power connection is established.

Switching on: Connect power plug to the socket.
Switching off: Disconnect the power plug.

Maintenance and cleaning

Attention! Dangerous electrical voltage.
Possible consequences: Death or serious injuries.
Protective measures:

Electrical units and installations with a rated voltage of U > 12 V AC or U >30 V DC located in the water: Isolate the units and installations (switch off and disconnect from the power supply) before reaching into the water.
Isolate the unit before starting any work.
Secure the unit to prevent unintentional switching on.

WARNING
This pump uses a very strong magnet to achieve superior performance. When removing the impeller assembly there will be considerable magnetic force resisting the extraction of the impeller assembly. This is normal. Likewise when replacing the impeller assembly there will be a strong magnetic force pulling the assembly into the pump to potentially cause injury to fingers and in rare cases damaging the ceramic shaft or rear bearing. Use thick gloves when replacing the impeller assembly.

Cleaning the unit

Regular cleaning of the pump may be necessary depending upon the environment in which it is operated. Clean the pump when it is visibly soiled or when a drop in performance is detected. Clean the unit with warm water using a soft brush.
Never use aggressive cleaning agents or chemical solutions.
These could attack the housing surface or impair the function.
In the event of stubborn furring (calcium deposits), a common household cleaner free from vinegar and chlorine can be used. Subsequently, clean the pump thoroughly using warm water.

Cleaning the pump

Disconnect the pump from the power source
○ Disconnect the tubing.
Disassemble the screen and remove the impeller housing to expose the impeller assembly.
Remove the impeller assembly by pulling on the back round plate behind the impeller
Use a soft cloth or brush to clean the impeller assembly and the inside of the impeller housing.
● Check parts for damages such as cracked rotor, shaft, or bearing,cracks in the magnet, and broken plastics.
Replace parts if necessary.
Reassemble in the reverse order.

Storage/Winterization

Put the unit out of operation at water temperatures below 46 °F (8 °C) or, at the latest, when freezing temperatures are to be expected.
Thoroughly clean the unit, check for damage.
Ensure that the storage place is inaccessible to children.

Wear parts

The impeller unit is a wear part and is excluded from the warranty.

Disposal

Do not dispose of this unit with domestic waste! Disable the unit beforehand by cutting off the cables. Further information about the recycling of this product can be obtained from your local municipal authority

Issue	Cause	Solution
The unit is not performing its suction function	Power supply not connected

Connect pump power supply, check the supply lines to make sure the voltage is correct
Impeller blocked, shaft broken| Remove the inlet screen and/or pump cover, and impeller housing to expose the impeller. Turn the impeller to ensure that it is not broken or jammed by debris. Also check to make sure that the ceramic shaft or bearings are not broken.
Pump is not completely submerged| Completely submerge pump in the water
Insufficient flow| Pump is not completely submerged| Completely submerge pump in the water
Screen clogged| Clean
Tubing blocked| Clean or replace tubing
Tubing kinked| Eliminate kink, replace tubing if it is damaged
Excessive flow loss in the tubing due to friction|

Reduce tubing length to reduce frictional loss
Select larger hose diameter, adapt stepped hose adapter to hose diameter.

Pump overload. The flow is automatically stopped to protect the pump.|

Clean the pump housing and impeller assembly
Reduce the ambient temperature (e.g. ensure that the specified water temperature is adhered to, avoid direct sunlight)

Impeller worn| Replace impeller assembly
Unit switches off after a short running period| Excessive soiled water| Clean impeller housing, bearing and impeller assembly
Impeller blocked, shaft broken| Remove the inlet screen and/or pump cover, and impeller housing to expose the impeller. Turn the impeller to ensure that it is not broken or jammed by debris. Also check to make sure that the ceramic shaft or bearings are not broken.
