Operating Instructions

IMPORTNT SAFETY INSTRUCTIONS
WARNING To guard against injury, basic safety precautions should be observed, including the following.
1) READ AND FOLLOW ALL SAFETY INSTRUCTIONS.
2) 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. a) If the appliance shows
any sign of water leakage, immediately unplug it from the power source.
b) Carefully examine the pumps after installation. It should not be plugged in if there is water on parts not
interned to be wet.
c) Do not operate the pumps if it has a damaged cord or plug, or if it is malfunctioning or has been dropped
or damaged in any manner.
d) To avoid the possibility of the pumps 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 travelling along the cord and coming in
contact with the receptacle.
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
3) Close supervision is necessary when any appliance is used by or near children.
4) Always unplug an pump from an outlet when not in use, before putting an or taking off parts, and before
cleaning. Never yank cord to pull plug from outlet. Grasp the plug and pull to disconnect.
5) Do not use the pump for other than intended use. The use of attachments not recommended or sold by
the appliance manufacturer may cause an unsafe condition.
6) Make sure an appliance mounted on a tank is securely installed before operating it.
7) Read and observe all the important notices on the appliance.
8) 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 bee taken to arrange the cord so that
it will not be tripped over or pulled.
9) This pump has a polarized plug (UK and US version). As safety feature, this plug will fit in a polarized
outlet only one way. If the plug 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.
Removing of the plug invalidates the warranty!

E-FLOW24VPUMPS
Deltec E-Flow pumps are brushless motor, true sine wave 24V DC pumps.
They come with a separate controller. The power consumption and performance can
be selected with the up/down buttons located on the face of the controller. The
pump itself can be installed either dry outside the sump or submersed inside the
sump or aquarium. The controller is not submersible.
Important safety instructions
Deltec E-Elow24V pumps are designed /manufactured according to existing technical
standards and safety regulations. However there is a potential risk to persons and
goods if the pumps or safety instructions are not being observed. Persons under the
age of 16 or persons who are unable to understand possible risks or do not fully
understand the safety and operating instructions are not allowed to use this pump
for safety reasons.
Keep these instructions in a safe place where it is accessible at all times.
Please read the following instructions very carefully before installing the
pump. Should you still have questions please contact your supplier.
Installation of the pump
- Always unplug the pump during the installation process.
- After unpacking check pump, controller and cables for any damage. If any
components show signs of damage, do not use the pump.
- The pumps are designed for ‘dry’ or submersible installation in fresh or seawater
aquarium systems.
- The pumps are not self priming and need to be installed below the water level.
- The separate controller must be placed in a dry, cool area, to prevent damage to
the electronic control circuits through water or dampness.
- To install, place the pump on a firm, even surface.
- Never select pipes or hoses smaller in diameter than that of the pumps suction
and pressure side fittings. Shut off valves should be selected one size bigger and
fitted with reducers down to the normal pipe diameters, since the normal inner shut
off valve diameter restricts the flow considerably.
- To achieve best performance, plan the piping as short as possible, use slow bends
instead of elbows.
- On longer pipe installation increase the diameter of the pipes. Instead of 32 mm
use 40 mm, etc.
- It is good practice to use a straight length of pipe of app 300 mm on the suction
side of the pump. This will give a laminar flow into the pump and prevent unwanted
noises
- Never run the pump dry, this may lead to irreparable damage.

- Never put your fingers into the pump’s suction or pressure side with the pump
connected to mains electricity.
- When using flexible hoses make sure that they are suitable for the pumps
performance and do not leach out dangerous substances into the water.
- When using non return valves ensure proper function, otherwise there is great
danger of the pumps running dry.
- If required, use a strainer with app 2-3 mm opening on the suction side. When
using finer filtration (sponges etc) make sure that they are always cleaned at short
intervals, to prevent cavitations and possible damage to the pump.
- Do not operate the pump with a shut off valve on the suction side, partly or fully
closed.
Installation of the controller
Install the controller in a dry, suitably vented place, away from water, dampness
and other heat sources like sunlight, artificial light etc.
Starting the pump
Check that the power supply is suitable for the pump. Refer to the pumps label.
Use the pump with an electric circuit breaker.
Overload protection
E-Flow pumps are protected against overloading. If the impeller is blocked the
pump is switched off automatically. If the cause of the blockage is removed the
pump can be restarted or will start on its own.
Power cut new start
After a power cut or the pump having being switched off, the pump will assume its
old setting when the power comes back on.
