IMPORTANT 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) 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.
b) For added safety, all electric devices must be connected to an RCD (Residual Current
Device).
c) 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 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) 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.
5) Make sure an appliance mounted on a tank is securely installed before operating it.
6) Read and observe all the important notices on the appliance.
7) 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.
8) This appliance has a polarized plug (one blade is wider than the other). 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!

Deltec Skimmer Series
Skimmer of the Deltec Skimmer Series are designed to operate only in external filter
sumps.
Installation
Please refer to the technical data for the recommended water level in the sump (Fig. 1).
A prerequisite for continuous efficient performance is a constant water level in which the
skimmer operates. Ideally, a water level top up system should be used or better still a
separate skimmer compartment in the sump (picture 2).
The water level in the skimmer compartment should be higher than in the rest of the sump,
but within the levels recommended for the skimmer model. (6 inches to 10” inches
This compartment can be supplied with water from a bypass of the aquarium overflow.

- 4 -
Safety Overflow
Skimmers of the “i” and “ix” series have a safety overflow and a regulator tube. These are
not glued to the footplate and can be interchanged as required (pictures 3,4 and 5). It must
be ensured that the outlet of the regulator tube points inwards, as if the skimmer is
removed too quickly from the filter chamber, water can be forced over the edge of the filter
sump.
If the safety overflow is not desired, the emergency overflow pipe can be removed and the
opening can be closed with the supplied plug, (picture6).

- 5 -
Starting the skimmer
-position the skimmer in the sump
-Remove the suction pipe above the safety overflow or turn to the side (picture 5).
-feed water into the skimmer compartment (if applicable)
-open the water level adjuster (picture 7) fully by turning it anti-clockwise
-start the skimmer pump
-Only for 400i - 2000i: Set the pump controller to the lowest level.
-close the water level adjuster until fine bubbles are visible between the bayonet and
the bottom of the skimmer cup (picture 8)
-initially keep the foam level in the skimmer cup low to avoid over skimming and
possible flooding of the cup.
-wait a minimum of 48 hours before the final adjustment, only then adjust the
controller up and down.
-The specified at the safety overflow pipe min and max. Values for the water level are
not to be considered in the start-up phase.
-Only for 400i - 2000i: After the start-up phase, set the controller to level 7 (400i)
level 5 (600i), level 7 (1000i), level 7 (1500i) or level 8 (2000i), optimal for most
aquariums.
-turn the water level adjuster in or out until the fine air bubbles start bursting
approximately halfway up the cup riser tube
-Set the water level between min. and max.
-Position the suction pipe above the safety overflow pipe.
-If the safety overflow pipe is not used, adjust the water level in the area of the upper
edge of the pipe, lower edge of the bayonet (picture. 8). The suction tube can be
removed.
-for dry foam turn the water level adjuster anti-clockwise, for wet foam clockwise
-Important: Never allow the pump to run dry.
Only for 400i - 2000i: When pressing the feed timer button on the controller, the pump
will stop for 10 minutes and will resume automatically.

- 6 -
Operation with ozone
Ozone is an extremely aggressive gas which - if not used properly - can damage one's
health. For this reason, ozone should never be breathed in directly.
In addition, at high doses ozone can damage the skimmer.
The dosing of ozone must be set so that no free ozone can be discerned on the skimmer lid.
Deltec skimmers can be operated with 50 mg/h of ozone per pump. An ozone-resistant T-
piece (Glass) should be fitted in the air hose above the skimmer pump. The free end of the
T-piece is connected to the ozonizer by means of an ozone-resistant hose.
In addition, if necessary (depending on the skimmer) an air valve must be installed.
It must be throttled until air is independently sucked through the ozonizer. The skimmer
can be operated with ozone up to max. 50 mg/h per pump. The air connection of the
ozonizer should be connected via a suitable silicon hose to the protein skimmer pump. The
air is automatically sucked in the ozonizer by the skimmer pump. Should the skimmer
performance deteriorate please check the ozonizer for blockage.
Safety information:
-The maximum ozone quantity of 50mg/hour per pump must not be exceeded.
-The air passage can be reduced as a result of dust deposits in the ozonizer. This can
result in an increase in the water level in the skimmer, which - in extreme cases - can
overflow. To avoid this, check the ozonizer regularly to make sure that there are no
deposits of dust. If necessary, clean it.
-Never breathe in free ozone.
-The ozonizer may not be directly connected to the air valve.
-In order to avoid water damage, the ozonizer must be placed high enough to ensure
that no water can penetrate it when the skimmer pump is switched off.
Fresh saltwater
If the skimmer is used with new saltwater on an aquarium it is common for find an
excessive quantity of small bubbles and often the skimmer cup fills with a clear liquid. This
is due to the high surface tension of the new seawater which prevents the bubbles from
bursting. Once the water matures this effect will go away but can take up to 2-3 weeks. The
effect is different on different salt brands and is often dependent on levels of conditioning
agents added to the salt. Once these are skimmed out then the skimmer will act normally.
Heavier feeding in the initial stages will give the chemically pure water something to react
with and allow it to mature and assist with normal protein skimming.

Maintenance
The Deltec skimmer range should need very little adjustment and maintenance once set
correctly however due to the high levels of calcium in marine aquariums it is common for
deposits to build up on moving parts requiring periodical cleaning. It is recommended every
6 months, or when required, that the pumps are removed from the skimmer having first
drained the body of Water.
Check and clean the impeller of debris. Soak the neck of the pump housing in white vinegar
or lime scale remover to dissolve any calcium carbonate deposits. A build up of calcium,
dust and salt can restrict or block the venturi inlet on the connecting pipe work and reduce
the skimming efficiency. This should be checked and carefully cleaned with a toothpick or
fine drill rotated between the fingertips.
It is advisable to stop the pump for approximately 15 minutes once every week in order to
dissolve any dust or salt crystals that may have collected in the venture tube.
Please observe: The water level adjuster must be checked at regular intervals (at least
once a week) for accumulation of dirt or other substances with may inhibit or interfere with
its proper function. If required please clean. For this purpose the water level adjuster can be
simply removed by pulling it upwards. After reinstallation of the water level adjuster please
make sure it is correctly set. Any foreign bodies, limestone build up ect. can cause the
skimmer water level to raise, in extreme cases the skimmer may get flooded.
