IMPORTANT SAFETY INSTRUCTIONS
WARNING - To guard against injury, basic safety precautions should be observed, including the following:
A) READ AND FOLLOW ALL SAFETY INSTRUCTIONS
B) 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:
1) CAUTION: If the appliance falls into the water, DON’T reach for it! First unplug it and the retrieve it. If electrical
components of the appliance get wet, unplug the appliance immediately. (Non-immersible equipment only)
2) If the appliance shows any sign of abnormal water leakage, immediately unplug it from the power source. (Non-
immersible equipment only)
3) Carefully examine the appliance after installation. It should not be plugged in if there is water on parts not intended
to be wet.
4) 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.
5) To avoid the possibility of the appliance plug or receptacle getting wet, position
aquarium stand and tank or the fountain 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 A should be arranged by the user for each cord connecting an aquarium
appliance to a receptacle. The “drip-loop” is the 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. If the plug or receptacle does
get wet, DON’T unplug the cord. Disconnect the fuse or circuit breaker that supplies
power to appliance. Then unplug and examine for presence of water in the receptacle.
C) Close supervision is necessary when any appliance is used by or near children.
D) To avoid injury, do not contact moving parts or hot parts such as heaters,
reectors, lamp bulbs and the like.
E) 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.
F) 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.
G) Do not install or store the appliance where it will be exposed to the weather or to temperatures below freezing.
H) Make sure an appliance mounted on a tank is securely installed before operating it.
I) Read and observe all the important notices of the appliance.
J) 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.
K) This appliance has a polarized plug (one blade is wider than other). As a safety feature, this plug will t in a
polarized outlet only one way. If the plug does not t fully in the outlet, reverse the plug. If it still does not t, contact
a qualied electrician. Never use with an extension cord unless plug can be fully inserted. Do no attempt to defeat
this safety feature.
EXCEPTION: This instruction may be omitted for an appliance that is not provided with a polarized attachment plug.

This protein skimmer is used to remove pollutants from the marine aquarium water, such as
proteins, dyes, phenols, albumin, etc. With a mixture of water and air produced in the reaction
column and the properties of salt water, dense foam is generated and collected in the collection
cup. Because various pollutants accumulate within the foam that is then extracted from the
aquarium water, the overall organic load of the aquarium is decreased. Additionally, the division™
series protein skimmer will increase oxygen content in the system, increase oxidation/reduction
potential (redox level), and aid balance of pH and the overall cleanliness of the system.

Installation
5. Connect the Pump (G) onto the Reactor Column (C) using the compression ring by turning the
ring clockwise onto the threads.
6. Once the Pump (G) in mounted to the Reaction Column (C), the Venturi Injector (L) should be
in a vertical position as shown in Figure 2.
7. Attach the Drain Tube (E) to the Support Base (A) and tighten the compression ring as shown
in Figure 2.
8. Attach the Drain Spillway (H) on the top of the Drain Tube (E).
9. Slip the Filter Sock (M) through the Drain Spillway (H) and place the Sponge (I) on top of the
drain hole.
10. Attach the Tubing (N) at the attachment point N.2 to the Venturi Injector (L).
11. Attach the other end of Tubing (N) to the bottom of the Air Silencer (F) as shown in Figure 2.
12. The Air Silencer (F) can then be hung in a variety of positions on the Drain Spillway (H)
utilizing the mounting post of the Air Silencer (F)
13. Insert the Water Control Screw (K) into the Venturi Injector (L) lightly so as to leave the ow
open.
14. Place the Collection Cup (D) securely on top of the Reaction Column (C) as shown in Figure 2
Place the skimmer inside of the aquarium system’s sump in an accessible and convenient
position for regular maintenance and cleaning and also preferably near where water comes into
the sump from the aquarium.
The design of the division™ skimmer offers various positioning options to optimize space by
rotating the Drain Tube (E), Drain Spillway (H) or the Collection Cup (D).
For initial setup please follow these steps making sure that the aquarium’s sump is at its
appropriate water level rst:
After placing the skimmer in the aquarium’s sump as above, orient the Drain Spillway (H) such
that it ows water away from the Pump (G).
1. Remove the Collection Cup (D).
2. Check and adjust as necessary the Water Control Screw (K) of the Venturi Injector (L) on the
Pump (G) and the Air Intake Screw (F.1) of the Air Silencer (F) so that they are fully open.

3. ATTENTION: While the division™ skimmer is not affected by changes in water level, the
Pump (G) must never be allowed to run without being submerged. Do not run the pump
if water drops below the ~MIN~ waterline mark on the Pump (G) Figure 3. Plug in the
Pump (G) and ensure it is operating to ll the Reaction Column (C) with both water and air
bubbles.
4. Adjust the height of the Drain Tube (E) and Drain Spillway (H), see Figure 3, by turning the
threaded rod clockwise to raise the level and counterclockwise to lower the level of the
water and foam in the Reaction Column (C). The level should be adjusted so that the top of
the foam is at the highest level without overowing. While this level will be very stable, it is
important to wait a few moments to allow for stabilization of the system as a whole.
5. Replace the Collection Cup (D).
6. Upon initial setup, it is important to check the level of the foam every couple of hours as the
new plastic components can inhibit foam production briey.
7. Once the level in the Reactor Column (C) is fully stable, foam will begin to build and climb
up into the Collection Cup (D). Make any adjustments to the level of foam by raising or
lowering the Drain Tube (E) and Drain Spillway (H). Raise the level by turning the Threaded
Rod (E) clockwise (up), and lower the level by turning it counterclockwise (down).
Figure 3

10
In this manner, ow of water from the Pump (G) and the ow of air from the Air Silencer
(F) are always maximized. Initially the foam may be fairly wet in nature. To make the foam
more concentrated in waste, lower the level. If very little foam is climbing over the edge
of the cup after a few days then raise the level. It is normal that in the rst few days of
operation, the skimmer may ll with a clear liquid. In time, the collected liquid (skimate)
will become darker in color and more concentrated with waste from the aquarium. Fine
adjustments can be made by turning the Air Intake Screw (F.1) on the Air Silencer (F)
however this would should only be done when there is simply too much foam created and
the foam cannot be controlled by lowering the water level by adjusting the Drain Tube (E)
and Drain Spillway (H).from the aquarium.
NOTE: While most marine or saltwater can be skimmed easily, a specic gravity of 1.026 or a
salinity of 35 ppt is recommended for best results.
When used in completely new aquariums, the foam can be suppressed for several days. This
is temporary and is due to various rubber and plastic parts used to setup the aquarium having
compounds that inhibit foam.
In some special cases, the air intake can be regulated, but it is an operation to be carried out
after having acquired some experience with the skimmer. An excessive closure of the air supply
could damage the needle impeller of the pump.
Maintenance
1. Before proceeding with maintenance, disconnect power to the Pump (F).
2. Check the skimmer daily for the level of collected liquid (skimate). If the skimate continues
to be clear after a few days of operation, the level of foam can be lowered slightly to
concentrate the skimate more. If the foam does not continue to produce a skimate, then
the level of foam can be raised slightly. It is important to make adjustments in very small
increments and then allow time for the adjustment to take effect. The ne-tuning of the
skimmer level will come with experience.
3. When the level of skimate in the Collection Cup (D) reaches 3-4 cm (1-2”), it is recommended
that the Collection Cup (D) be removed and cleaned. A cleaner inner column of the
Collection Cup (D) results in better skimate production. As an option the Collection Cup (D)
has a drain where a small hose can be connected to drain into a larger reservoir such as a
small bucket or jug for longer periods between cleaning.
4. It is recommended to check the Air Silencer (F) and the Tubing (N) weekly to make sure they
are clear of any salt, dust or dirt build up. An increase in noise or vibration can indicate an
obstruction of air ow.

11
5. Check the Pump (G) monthly. The skimmer is designed with an external pump connected by
a compression ring. This allows for quick and easy cleaning of the Pump (G).
6. If salt or limescale deposits are present, it is recommended to clean the affected parts with
water and vinegar away from the aquarium sump.
7. Do not use detergents or solvents that could damage the product or be harmful to aquatic
organisms.
8. If the pump runs with the intake or impeller blocked for extended periods of time due to
debris or encrustations, it could cause irreversible damage.
9. The Filter Sock (M) and Sponge (I) should be cleaned by gently rubbing and rinsing every
1-2 weeks. Though replacement needs will vary, the Filter Sock (M) and Sponge (I) should
be replaced every couple of months.
Secondary Pump Conguration (optional)
O. Secondary Pump
P. Venturi Extension
Q. O-ring
R. Connecting Hose
The Secondary Pump Kit (sold separately) allows you to nely adjust the amount of water you
want to treat. The Pump (G) recirculates water and air on itself, reducing consumption because it
does not have to fulll the task of loading the water, but is optimized completely for skimming.
The Secondary Pump Conguration (Recirculating) allows the adjustment of three parameters
independently:
1. Water ow rate to the skimmer is controlled by the Secondary Pump (O)
2. Foam level is controlled by the threaded rod on the Drain Tube (E)
3. Air ow to the skimmer is controlled by the air intake screw of the Air Silencer (F)
The Secondary Pump Kit consists of:

2. Remove the Water Control Screw (K).
3. Insert the Venturi Extension (P) onto the Venturi Injector (L)
4. Remove the cap from the Support Base (A) just under the Pump (G) by unscrewing the
compression ring (A.1).
5. Insert the Venturi Extension (P) into the O-ring (Q) and secure everything with the
Compression Ring (A.1) as in Figure 5.
6. Connect the Secondary Pump (O) with the Connecting Hose (R) to the inlet connector (C.1)
as in Figure 5.

Troubleshooting
Symptom Possible Causes Solution
The skimmer produces
foam, but the foam
does not rise into the
Collection Cup.
Newly set-up aquarium or new
skimmer.
Wait for the living organisms to
produce a greater organic load and
for the skimmer to exceed an initial
running time of 2-3 days.
The water level of the sump is too
low for the skimmer and the pump
does not suck in enough water to
work properly.
Restore the minimum recommended
water level in sump.
The water level inside the skimmer
is too low.
Use the adjustment rod on the Drain
Tube (E) to raise the water level.
The foam is drastically
reduced in the skimmer
Food was administered. Some foods
contain fatty acids and oils that can
inhibit skimming.
Wait a few hours for the normal
biological process to improve the
conditions.
The aquarium may have reached a
biological maturation level such that
it produces little organic residue.
This balance is rare and is usually
not constant.
It will normally correct itself over time.
Pump or air intake system are dirty. Disassemble and clean thoroughly
The pump is noisy The water level of the sump is too
low for the skimmer and the pump
does not suck in enough water to
work properly.
Restore the minimum recommended
water level in sump.
The pump intake is blocked. Dismantle the pump and check
that all its parts are in order. Check
the cleanliness and positioning of
the impeller and any presence of
limescale.
Lime and salt deposits and/or
natural wear
Replace the impeller
