EHEIM 2048 Internal Filter Instruction Manual

IMPORTANT SAFETY INSTRUCTIONS

WARNING – To guard against injury, basic safety precautions should be observed, including the following.

READ AND FOLLOW ALL SAFETY INSTRUCTIONS.
DANGER – To avoid possible electric shock, special care should be taken since water is employed in the use of aquarium equipment. For each of the following situations, do not attempt repairs by yourself; return the appliance to an authorized service facility for service or discard the appliance.

If the appliance falls into the water, DON’T reach for it! First unplug it and then retrieve it. If electrical components of the appliance get wet, unplug the appliance immediately. (Non-immersible equipment only)
If the appliance shows any sign of abnormal water leakage, immediately unplug it from the power source. (Immersible equipment only).
Carefully examine the appliance after installation. It should not be plugged in if there is water on parts not intended to be wet.
Do not operate any appliance if it has a damaged cord or plug, or if it is malfunctioning or has been dropped or damaged in any manner.
To avoid the possibility of the appliance plug or receptacle getting wet, position aquarium stand and tank to one side of a wall-mounted receptacle to prevent water from dripping onto the receptacle or plug.

A ”drip-loop”, shown in the figure below, should be arranged by the user for each cord connecting an aquarium appliance to a receptacle. The ”drip-loop” is that part of the cord below the level of the receptacle, or the connector if an extension cord is used, to prevent water traveling along the cord and coming in contact with the receptacle.
DRIP LOOP SAFETY
If the plug or socket does get wet, DON’T unplug the cord. Disconnect the fuse or circuit breaker that supplies power to the appliance. Then unplug and examine for presence of water in the receptacle.

Close supervision is necessary when any appliance is used by or near children.
To avoid injury, do not contact moving parts or hot parts such as heaters, reflectors, lamp bulbs, and the like.
Always unplug an appliance from an outlet when not in use, before putting on or taking off parts, and before cleaning. Never yank cord to pull plug from outlet. Grasp the plug and pull to disconnect.
Do not use an appliance for other than intended use. The use of attachments not recommended or sold by the appliance manufacturer may cause an unsafe condition.
Do not install or store the appliances where it will be exposed to the weather or to temperatures below freezing.
Make sure an appliance mounted on a tank is securely in stalled before operating it.
Read and observe all the important notices on the appliance.
If an extension cord is necessary, a cord with a proper rating should be used. A cord rated for less amperes or watts than the appliance rating may overheat. Care should be taken to arrange the cord so that it will not be tripped over or pulled.
This appliance has a polarized plug (one blade is wider than the other). As a safety feature, this plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Never use with an extension cord unless plug can be fully inserted. Do not attempt to defeat this safety feature. Exception: This instruction may be omitted for an appliance that is not provided with a polarized attachment plug.
”SAVE THESE INSTRUCTIONS”.

GROUNDING INSTRUCTIONS

This appliance should be grounded to minimize the possibility of electric shock. This appliance is equipped with an electric cord having an equipment grounding conductor and a grounding-type plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all appropriate codes and ordinances. This appliance is for use on a nominal 120 V circuit, and has a grounding plug that looks like the plug illustrated in Sketch A. A tempory adapter which looks like the adapter illustrated in Sketches B and C , may be used to connect this plug to a two pole receptacle as shown in Sketch B if a properly grounded outlet ist not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. The green colored rigid ear (lug, etc.) extending from the adapter must be fastened to a permanent ground such as a properly grounded outlet box.
GROUNDING INSTRUCTIONS

Safety instructions

For indoor use only. For use with aquariums.
All electrical equipment in the water must be disconnected from the mains during care and maintenance work.
It is imperative to disconnect the filter from the mains prior to opening it.
The connecting line of this device can not be replaced. When the line is damaged, the device must no longer be used. Contact your specialized dealer or your EHEIM Service Centre.
This equipment is not intended for use by persons (including children) with limited physical, sensory or mental abilities or for persons with no experience or knowledge unless they are supervised by a person responsible for safety or unless they have received from such a person instructions on how to use the equipment. Children should be supervised to ensure that they do not play with the equipment.
Notice: These devices produce magnetic fields which might cause electronic and mechanical disturbances or damages. This also refers to pacemakers. Please consult the manuals of medical equipment for the required safety margins.
Attention: Maintenance work presents the risk of crushing the fingers due to high magnetic forces.
For your own safety, we recommend to form a drip loop with the connection cable to prevent any water running along the cable from intruding into the socket. When using a multiple socket or an external power supply unit, position them atop the filter’s power connection.
Take the necessary precautions when handling components that can discharge static electricity.
Do not clean the unit – or parts of it – in the dishwater. Not dishwater resistant!
Do not dispose of this product as normal household waste. Take it to your local refuse collection side.

Clamping plug
Suction cup.

Installation

B Clip clamping plug into apertures in retaining plate. Install suction pads. If preferred, the retaining plate can be attached to one side of the pump, permitting the filter to be installed facing in any direction.
C/ D Screw in either discharge connection (C) or diffusor (D) as required. Discharge connection: used for good water surface movement. Height of filter is regulated by means of perforated locking device on mounting support. Diffusor: This is preferable for aquariums without plants.
The oxygen supply can be regulated by the air regulating valve. Open filter shutter and secure filter in aquarium (for minimum immersion depth, see diagram C). Connect electrical plug to initiate filter operation.

Putting into operation

E Modules can be easily separated by the application of light pressure on the locking points at the sides.
The cartridges (order no. 2615480) should be washed out and re- placed alternately to prevent the biological filtering process from being interrupted. This is necessary when the pump performance becomes noticeably reduced. CAUTION: Make sure you close the filter shutter before removing the filter.
F The filtering area can be changed individually by reducing or extending the modules. (Accessory item – order no. 7478860, filter module with filter cartridge.)
