Frequently Asked Questions - Aquarius Fountain Set Eco 9500 OASE

How do I install the Aquarius Fountain Set Eco 9500?

Place the pump horizontally on firm, sludge-free ground in the pond, ensuring it is completely submerged. Assemble the telescopic extension, nozzle, and flow regulator as per the manual. Connect the hose if needed. For detailed steps, refer to the Installation and connection section.

What should I do if the pump doesn't start?

Check the mains voltage and supply lines. Ensure the filter housing is not clogged. If the impeller is blocked, disconnect power and remove the obstacle. The pump may also shut off due to thermal protection; let it cool down before restarting.

How do I clean the pump?

Disconnect the power plug. Unscrew the transition piece, remove the screws to open the filter housing, take out the pump, and remove the pump casing screws. Pull out the impeller unit (magnetic resistance). Clean all parts with clear water and a soft brush. For limescale, use OASE PumpClean or a vinegar-free household cleaner. Reassemble in reverse order.

Can I use this pump in a swimming pond?

No, never operate the unit in a swimming pond. Severe injuries or death can occur due to electrification of water from defective electrical components. It is intended only for garden ponds, ornamental fountains, and water courses.

How does the Environmental Function Control (EFC) work?

The pump automatically performs a self-test at startup and every 20–40 minutes. It detects dry running, blockage, or submersion. If dry or blocked, it shuts down after 60–120 seconds. To reset, disconnect power, flood the pump or remove the obstacle, then restart.

What is the maximum water temperature allowed?

The maximum water temperature is +35 °C. If exceeded, the pump will switch off via thermal protection and restart automatically after cooling.

How do I store the pump for winter?

Thoroughly clean the unit, check for damage, and store the pump submerged in a frost-free environment. Protect open plug connections from moisture and dirt. The pump is not frost-proof and must be removed if freezing temperatures are expected.

Can I use a dimmer to control the pump speed?

No, do not connect the unit to a dimmable power supply. The pump contains sensitive electrical components that will be destroyed by a dimmer. Use the integrated flow regulator to adjust flow rate.

What are the permissible water quality parameters?

Permissible water quality: pH 6.8–8.5, hardness 8–15 °dH, free chlorine <0.3 mg/l, chloride <250 mg/l, salt content <0.4%, total dry residue <50 mg/l. Only use fresh pond water; do not use chemicals or other fluids.

What does the magnet in the pump mean for pacemaker users?

The impeller unit contains a strong magnet that may affect pacemakers or ICDs. Keep a distance of at least 0.2 m between the implant and the magnet. The unit is marked with a warning symbol for persons with pacemakers.

Installing the unit

WARNING

Severe injuries or death due to operation of this unit in a swimming pond. Defective electrical components will electrify the water with dangerous electrical voltage.

▶ Never operate the unit in a swimming pond.

NOTE

If the pump is used for conveying excessively soiled water, the impeller unit will be subject to increased wear and will require earlier replacement.

▶ Thoroughly clean the pond or pool before installing the pump.
▶ Install the pump at a raised level above the bottom. This reduces intake of muddy water.

How to proceed:

- Install the unit in the pond in a horizontal position on firm, sludge-free ground and ensure that it is completely covered with water.

ARS0015

Commissioning/start-up

CAUTION

Risk of injury due to unexpected start-up. Internal monitoring functions may switch off the unit and automatically reactivate it.

▶ Disconnect the power plug before carrying out any work on the unit.

NOTE

The unit will be destroyed if it is operated with a dimmer. It contains sensitive electrical components.

▶ Do not connect the unit to a dimmable power supply.

Switching ON/OFF

- Switching on: Plug the power plug into the outlet. - The unit switches on immediately.

- Switching off: Pull the power plug from the outlet.

Environmental Function Control (EFC)

When started up and then every 20 ... 40 minutes the pump automatically performs a pre-programmed self-test (Environmental Function Control (EFC)). The pump detects if it is running dry / clogged or submerged. The pump shuts down automatically after 60 to 120 seconds if it runs dry/is blocked. In the event of a malfunction, disconnect the power supply and “flood the pump” or remove the obstacle. Afterwards, the unit can be restarted.

Setting the flow rate

Setting the spray pattern and flow rate:

• Adjust the flow regulator so that the nozzle produces the desired spray pattern.
• Adjust the flow regulator to achieve the desired flow rate for the water course.

OPREZ

Environmental Function Control (EFC)

Pumpa prilikom stavljanja u pogon, a zatim tijekom rada svakih 20 ... 40 minuta automatski obavlja unaprijed programiranu samoprovjeru (Environmental Function Control (EFC)). Pumpa prepoznaje radi li pritom na suho, je li blokirana ili uronjena. U slučaju rada na suho ili blokiranja, pumpa se automatski isključuje nakon otprilike 60 do 120 sekundi. U slučaju neispravnosti prekinite dovod elektroenergije i „potopite pumpu“ ili uklonite prepreku. Nakon toga možete uređaj ponovno staviti u pogon.
