Cleaning/replacing the filter media

• Do not use cleaning agents or chemical solutions.
• If there are several foam filters, clean or replace the foam filters at different times. This saves enough useful bacteria to ensure good biological filtration of the water.

NOTE

Normal tap water destroys the bacteria colonies in the filter media. This will impair the cleaning effect.

- Only use water from the aquarium for cleaning the filter media.

Prerequisite:

- The motor head has been removed. ( Removing the motor head)

How to proceed:

1. Remo ve all filter media from the filter case.

TROUBLESHOOTING

Malfunction Possible cause Remedy
The motor head cannot be fastened to the filter case.	The arrows on the filter media container and on the filter case are not all pointing in the same direction. The filter media containers are incorrectly fitted.	Fit the filter media containers correctly.
	Too much filter media has been put into the filter media containers.	Remove excess filter media.
Water leakage from the motor head.	The locking clips are not properly closed. Close the locking clips properly.
	Dirt or foreign bodies are located on the filter case or motor head seal.	Clean all points where the motor head seal and filter case make contact.
	The motor head seal is incorrectly fitted, damaged or missing.	Correctly insert the motor head seal or replace.
	The edge of the motor head is damaged. Replace the motor head.
	The hose adapter is incorrectly fitted. Fit the hose adapter correctly.
The motor is not working.	The power supply is interrupted. Establish the power supply.
	The impeller shaft is broken. Replace the impeller.
	The impeller is missing or is blocked by foreign bodies.	Fit the impeller or clean.
Reduced water flow. The hose adapter is heavily soiled. Remove the hose adapter and clean with warm water.
Air trapped in the filter.	Insufficient distance between the filter and the water level in the aquarium.	Position the top edge of the filter head at least 10 cm below the level of the water.
	Filter media clogged. Clean the filter media.
	Air entering through the intake pipe.	• Route a hose between the intake pipe and filter below the level of the water in the aquarium.• Renew the O-ring on the intake pipe.
The filter does not start up correctly.	Filter media insufficiently cleaned. Clean the filter media.
	The filter media is contained in nets. Do not use filter media in nets or nylons as the filter will become clogged.
Unusual noises emitted when the filter starts up.	Air is entering through the hose connection.	Connect the hoses properly.
	Air trapped in the filter. Carefully shake the filter to allow the air to escape.
Unusual noises emitted from the filter during operation	Foam pre-filter clogged. Clean the foam pre-filter.
	Insufficient flow rate Open the stop valves to increase the flow rate.
	Insufficient lubrication of the O-rings. Apply a generous amount of commercially available lubricant such as Vaseline to the O-rings.
	Uneven water circulation due to insufficient intake of water.	Disconnect and reconnect the power plug to start up the filter again.
	Insufficient distance between the filter and the water level in the aquarium.	Position the top edge of the filter head at least 10 cm below the level of the water.
	Air trapped in the filter. Carefully shake the filter to allow the air to escape.
	There is a sound of air being emitted from the outlet pipe about every 10 seconds.	Air released by aquatic plants during photosynthesis and by bacteria causes the formation of air bubbles, which cause this sound. No measures necessary.
	The start button is pressed. Never press the start button when the filter is operating.Ensure that no objects accidentally press against the start button.
