Frequently Asked Questions - Waterrefill 3548 EHEIM

How to install the sensor of the Waterrefill 3548?

The sensor is attached to the outside of the aquarium glass using the provided adhesive tape. The surface must be clean and degreased (rubbing alcohol). Position the sensor above the water level, slowly lower it until the yellow LED turns off, then mark the position, remove the protective film, and press firmly for 10 seconds.

What do the LEDs on the controller mean?

Solid red LED indicates delivery state or reset; solid green means normal operation; flashing green indicates the pump is recharging; fast flashing red signals abnormal refill; slow flashing red indicates refill interval too short; alternating red/green signals a controller fault.

How to put the device into standby?

Briefly press the button on the controller. The green LED starts flashing quickly, indicating standby mode. To reactivate, press briefly again.

Can I use the Waterrefill in seawater?

Yes, the sensor can be used in freshwater or seawater. Ensure the water temperature does not exceed 35°C and regularly clean the glass in front of the sensor to avoid salt deposits.

What to do if the red LED flashes quickly?

This indicates that the refill duration is abnormal. Check that the water reservoir is not empty, that the hose is properly connected to the pump, and that the flow elbow is in the correct position.

How to maintain the pump?

In normal use with osmosis water, impeller cleaning is not necessary. If needed, use the appropriate spare parts kit. Refer to the manual for disassembly.

What is the maximum flow rate for the pump?

The maximum flow rate of the pump is 240 l/h. It is recommended to reduce the flow with the shut-off valve so that the refill lasts at least 15 seconds.

Can the sensor be placed near metal or cables?

No, the sensor must be kept away from any metal objects or electrical cables as they can cause malfunctions.

What is the function of the power cable loop?

It is recommended to form a loop with the power cable to prevent water from running down the cable and seeping into the socket.

How to reset the controller?

Press and hold the button on the controller until the red LED lights up continuously. Release, then press briefly to reactivate the system.

EHEIM waterrefill automatic refilling device item no. 3548

Scope of delivery

① power supply unit ② controller ③ pump ④ shut-off valve ⑤ sensor with adhesive strips ⑥ hosepipe ⑦ drain elbow ⑧ mount for the drainage elbow ⑨ retaining clamp 1x plug adapter for the power supply unit, 1x operating instructions, 1x guarantee card All parts, the plug-in power supply unit, the controller, the sensor and the refilling pump are wire with one another. The plug-in power supply units permanently wired to the controller. From the controller,② one cable goes to the sensor and another cable to the refilling pump.

Installation of the sensor

Do not remove the adhesive strips yet!

The sensor ^⑤ is fixed to the outer side of the basin (aquarium, filter basin, sump) with an adhesive strip; the water level of this basin must be monitored. The corresponding basin must be prepared such that the sensor can be fitted properly. The fixing position must be a dry area with no risk of splashed water. The pump should not be in the water as yet. The adhesive surface on the outer side of the glass panel must be dry, clean and free from grease. Clean the adhesive surface using methylated spirit. All-purpose cleaners, bathroom cleaners or similar are not suitable for use on the aquarium.

Now, connect the power supply unit to the socket; on doing this, the red LED ✗ C1) on the controller gets activated and glows constantly.

Then, place the sensor from outside on the glass panel of the basin above the water level in a horizontal position (both the LEDs ✉ S1 and ✉ S2 on the sensor glow) (☒ 1.).

Slowly move the sensor downwards (☒ 2.) until the yellow LED (☒ S2) goes out. Ensure that the sensor is in contact with the basin glass during this entire movement (☒ 3.).

On the basin, mark the position of the sensor, on which the yellow LED has gone out 4.). Only after this is done, pull out the protective foil of the adhesive strip (5.) and press the sensor forcefully on the glass in a horizontal position for 10 seconds (6.).

Caution: Do not bring the sensor and adhesive strip in contact with water / splashing water! Even very small quantities of water / water droplets between the glass pane of the basin and the sensor lead to malfunctioning!

Never place the sensor close to metallic objects or cables, these, too, lead to malfunctions!

Installation of the automatic refill device

Connect the hose ⑥ to the water outlet of the pump (☒P1). Then place the pump ③ in the water reservoir. Guide the hose ⑥ to the point on the aquarium at which the aquarium is to be filled with water and, where necessary, shorten the hose ⑥ to the required length. Insert the drain elbow ⑦ in the other end of the hose ⑥ and clip the mount (☒H2) to the elbow.

The outlet opening of the drain elbow ⑦ must always be installed above the water level. If the end of this tube is submerged in water, water from the filter basin or aquarium will flow in the reservoir or vice-versa, according to the principle of communicating pipes, until the water level in both the containers is the same.

In order to avoid wave movements in front of the sensor, the mount⑧ must be so fixed to the aquarium glass using the retaining clip (H1) that the water discharge is at least 5 cm away from the sensor. In addition, it is recommended, by means of the shut-off valve ④ to restrict the delivery rate of the pump ③ to the extent that the refilling operation takes at least 15 seconds.

Putting into operation

After the sensor is mounted on the basin glass, switch on the automatic refilling system by pressing the key on the controller. The indicator on the controller (LED ☒) changes colour from red to green. From this point, the EHEIM automatic water refill device monitors the water level of your aquarium.

In order to guarantee the detection of the water level, the inner sides of the aquarium must be regularly freed from contaminants such as limescale and salt crusts.

Attention: When changing the water or working in the aquarium, switch the automatic refill device into standby mode.

Operating the controller

Standby mode: To switch the automatic refill device to the standby mode, briefly press the button on the controller once. The standby mode is active when the LED on the controller rapidly flashes green.

Reset: To reset the controller, keep the button pressed for so long until the LED glows constantly red.

Switching on / activating: To take the automatic refill device out of standby mode or to reactivate after a reset, briefly press the button on the controller once.
