1 Safety
Please read and follow all safety instructions.
If the external cable Is damaged, It shall be replaced by the
manufacturer.
To avoid the possibility of the appliance plug or receptacle getting wet,
position the aquarium stand and tank to one side of a wall mounted
receptacle to prevent water from dripping onto the receptacle or plug.
You should create a “drip loop” (see Figure 1) 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. Use an extension
cord, if necessary, to prevent water traveling along the cord and coming
into contact with the receptacle. If the plug or receptacle does get wet,
DO NOT unplug the cord. Disconnect the fuse or circuit breaker that
supplies power to the appliance. Then unplug the device 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.
Always unplug an appliance from an outlet when not in use, before
putting on or taking off parts, and before cleaning. Never pull the cord
itself to remove the plug from the outlet. Grasp the plug and pull to
disconnect.
Do not use an appliance for anything other than its 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 appliance where it will be exposed to the
weather or to temperatures below freezing point.
Make sure an appliance mounted on a tank is securely installed before
operating it.
Read and observe all the important notices on the appliance.
NOTE: 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 cannot be tripped over or pulled accidental.
DANGER: To avoid possible electric shock, special care should be
taken when handling a wet aquarium. For each of the
following situations, do not attempt repairs yourself; return
the appliance to an authorized service facility for service or
discard the appliance.
WARNING: To guard against injury, basic safety precautions should be
observed, including the following:
Do not operate any appliance if it has a damaged cord or
plug, if it is malfunctioning, or if it is dropped or damaged
in any manner.

Room temperature
Site selection is important for correct temperature maintenance.
We recommended that you keep the ambient room temperature a
comfortable and stable 22°C / 72°F. Avoid placing the tank in front of
an air conditioner, heating vents or direct sunlight. A well ventilated
room with moderate light is the best place to position the aquarium.
Accessibility
Ensure that there is at least 10cm / 4” of clearance behind the
REEFER™to allow easy access for installing/removing cables from the
sump as well as sufficient air circulation for a chiller (larger models
only). It is recommended to leave approximately 60cm/24” between
one of the sides of the aquarium and any adjacent walls or furniture
for access to the rear of the tank.
General considerations
Ensure that the area surrounding the aquarium is waterproof and
consider moving away anything that water might damage or may be
corroded by the salt.
NOTE: The REEEFER™system should not be moved when full of water.

Ensure that you have the correct number of people to lift the aquarium
according to its weight and size.
Ensure that anyone lifting the aquarium is physically suitable for such an
operation and has been instructed in the correct methods of lifting heavy
objects.
Once the aquarium is correctly aligned with the cabinet, check that the
cabinet has not moved. If necessary readjust the position of the cabinet.
For units with adjustable legs: Using a spirit level on the top surface of
the glass tank, adjust the height of the legs to level the aquarium. Make
sure that all legs are touching the floor.
WARNING: If you are not experienced in the construction of self-
assembly furniture or the installation of aquarium systems,
seek suitably qualified assistance.
WARNING: Read before lifting the glass aquarium onto the cabinet.
NOTE: It is important to assemble the REEFER™in the order indicated.
NOTE: The REEFER™aquarium system should not be moved when full
of water.

ENG
Before placing the glass sump in the cabinet make sure that the cabinet
doors are correctly aligned (see instructions in the cabinet assembly
manual). Once the sump is in position it will not be possible to make
adjustments to the lower hinge without moving the sump.
With the doors properly aligned, rotate the front section of the push
opener to the correct extension so that the doors will pop open when
pushed.
Overflow box pipes: Make sure that that the O-rings are in position on
the threaded connectors before assembly. To ensure correct assembly,
firmly hold the threaded connectors from inside the cabinet and tighten
well by hand. Do not use tools. Avoid unscrewing the pipes from the
overflow box once assembled as the locking mechanism that prevents
counter-rotation will be less effective.
Sump pipes: Make sure that that the O-rings are in position on the
connectors before assembly. After assembly check that the pipes are
vertical and the securing nut is holding the pipe in position. Do not use
tools and do not overtighten.
Overflow Box Cover: The overflow box cover reduces noise from the
water fall of the surface skimmer. If you wish to use the rear wall of
the overflow box for mounting equipment such as lighting, break out
the section of the cover as shown in the graphic manual. After breaking
out the removable section, smooth the remaining edge with a file or
sandpaper.

4 Overview of the REEFER™
water management system
Surface Skimmer / Overflow Box
Surface water from the aquarium flows via the removable comb sections
of the surface skimmer into the overflow box that houses the dual
intakes of the silent-flow downpipe system and the outlet nozzle of
the sump return pump. The silent-flow downpipe system includes a
flow-regulated main downpipe and a secondary overflow bypass pipe.
An external pipe with a clear upper section is placed over the main
downpipe to ensure positive water motion throughout the entire height
of the overflow box.
The fine adjustment flow valve on the main downpipe enables the water
level in the overflow box to be maintained at a constant height between
the intakes of the main and bypass pipes, which ensures positive surface
skimming while eliminating all noise from the water flow to the sump.
An incorrect setting of the flow valve will be accompanied by the sound
of the water returning to the sump and is an indication that the flow
valve needs adjusting.
Sump /ATO
Water from the flow-regulated main downpipe and the secondary
overflow bypass pipe enter a compact reception chamber in the sump.
Care should be taken in the choice of any filter media placed in the
reception chamber as the turbulent flow conditions from the downpipe
could cause a constant discharge of fine media particles.
The water then flows through the 400 micron filter before entering the
constant-height main reactor or skimmer chamber. If the filter bags are not
cleaned frequently enough and become blocked, the water will bypass the
filter bags without affecting the overall operation of the sump.
A bubble trap labyrinth with coarse foam separates the reactor chamber
from the pump compartment to prevent bubbles from the skimmer being
returned to the aquarium.
Any loss of water due to evaporation will cause a drop in the water level
in the pump compartment of the sump which will be compensated by
the ATO system.
Maintaining a constant water height in the pump compartment (with the
ATO) is essential for the stability of the entire water management system
by ensuring a constant head pressure on the intake of the main pump.
The reservoir contains water for approximately 3 days of evaporation and
should be kept topped up at all times.
Return Pump
The recommended flow rates for the return pumps are as shown in the
table below. The use of higher rated pumps will result in a higher water
level in the aquarium unless an appropriate modification is made to the
surface skimmer combs.

5 Operation
Initial Fill
Check that all pipes are properly assembled and that any flexible tubes
are suitably secured in position.
Install any equipment that will take up water volume in the sump before
starting to fill the system.
Open the main flow valve (rotate anti-clockwise) to maximum.
Add approximately 15cm/6” of water to the overflow box to make sure
that all the pipe joins are watertight. Check for leaks inside the cabinet.
Add water to the main tank and once it is full, monitor the water level in
the sump as it begins to fill.
As soon as there is approximately 15cm/6” of water in the main pump
compartment switch on the pump and stop adding water.
Switch on skimmers or other filters that will affect the water level in the
sump and add more water as required to maintain the 15cm/6” of water
in the main pump compartment.
Allow the system to run for a few minutes and adjust the flow valve (as
described below) so that the water level in the overflow box is at the
correct level.
Add/remove water to/from the system and adjust the flow valve until
the water levels in the system stabilise.
Main downpipe valve adjustment
To raise the water level in the overflow box, rotate the valve clockwise.To
lower the water level in the overflow box, rotate the valve anti-clockwise.
The main downpipe flow valve provides a very fine control of the flow
rate however after making adjustments it takes the system a few
minutes to stabilize at the new setting.
Once you have established the approximate setting for the valve make
very small adjustments and wait for a few minutes each time. It may
take a number of occasional adjustments to reach a stable level. When
set properly this system removes all of the noise of water flowing down
to the sump.
ATO
On initial set-up, wait until the saltwater system is stable before using
the ATO. Ensure that the top-up flow valve is fully closed.
Fill the top-up reservoir with RO water. Disconnect the top-up flow valve
from the float valve and slowly open the flow valve until the top-up
water drips at a rate of approximately 1 drop per second. Reconnect the
flow valve to the float valve.
Adjust the angle of the float so that the valve is closed when the water
level is above the inlet of the pump but below the top of the bubble trap.
Power-out test
After completing the initial set up and after adding any new equipment
to the sump, make any adjustments necessary to the main valve to
stabilise the system and perform a “power-out” test to check that water
does not rise above the rim of the sump.
WARNING: Overfilling the sump with equipment or water may cause
a flood in the event of an interruption of electric power.
NOTE: It is recommended to close the valve on the outlet of the
reservoir whenever doing maintenance in the sump

6 Maintenance
For continuous smooth operation of the water management system make
regular checks of the following:
• Water level in the overflow box - adjust the flow valve as required
• Water level in the reservoir – top up with RO water as required
• Water level in the sump, check that the top-up float valve is
operating correctly
• Micron Filter Bags – check that water is flowing through the bags
and clean/replace as required
• Surface skimmer combs – remove any deposits that reduce water flow
• Pump outlet nozzle – check for blockages and build-up of algae
Micron Filter bags
It is recommended to have at least 3 sets of filter bags.
There are a few options for cleaning the filter bags:
Quick and effective – Spray the outside of the bags with a powerful
water jet such as a garden hose to back-flush the detritus from the
Polyester bag.
More thorough – soak the bags in bleach or diluted vinegar for 24 hours
prior to spraying as above. Rinse well to remove all chemicals before
returning to sump.
The filter bags can also be put in a cold wash in a washing machine with regular
detergent or with vinegar (may require approval from a higher authority).

1 Sicherheit
Bitte lesen und befolgen Sie alle hier aufgeführten Sicherheitshinweise.
Um ein Nasswerden des Gerätesteckers oder der Steckdose zu
vermeiden, stellen Sie Gestell und Becken des Aquariums neben einer
Wandsteckdose so auf, dass kein Wasser auf die Steckdose oder den
Netzstecker tropfen kann. Der Benutzer sollte eine „Tropfschleife“
(Abbildung 1) für jedes Netzkabel bilden, das ein Gerät des Aquariums
mit der Steckdose verbindet. Die „Tropfschleife“ ist der Teil des
Netzkabels, der unterhalb der Steckdose oder der Anschlussdose liegt.
Verwenden Sie nötigenfalls ein Verlängerungskabel um zu vermeiden,
dass Wasser am Kabel entlangläuft und mit der Steckdose in Berührung
kommt. Wenn der Stecker oder die Steckdose nass wird, Netzkabel
NICHT aus der Steckdose ziehen. Schalten Sie die Sicherung oder den
Sicherungsschalter des Stromkreises für das Gerät aus. Ziehen Sie
erst danach das Netzkabel des Gerätes heraus und überprüfen Sie die
Steckdose auf das Vorhandensein von Wasser.
Wenn das Gerät von Kindern oder in der Nähe von Kindern benutzt
wird, müssen diese gut beaufsichtigt werden. Zur Vermeidung von
Verletzungen keine Teile berühren, die sich in Bewegung befinden.
Ziehen Sie immer den Netzstecker eines Gerätes, wenn dieses nicht
in Gebrauch ist, bevor Sie Teile anbringen oder entfernen und vor
dem Reinigen. Ziehen Sie nie am Netzkabel, um den Netzstecker aus
der Steckdose zu lösen. Fassen Sie den Netzstecker an und ziehen sie
ihn heraus. Benutzen Sie ein Gerät immer nur für den vorgesehenen
Verwendungszweck. Die Verwendung von Anbauteilen, die nicht vom
Gerätehersteller empfohlen oder verkauft werden, kann zu einem
unsicheren Betriebszustand führen. Installieren oder lagern Sie das
Gerät nicht dort, wo es der Witterung oder Temperaturen unter dem
Gefrierpunkt ausgesetzt ist. Vergewissern Sie sich, dass ein an ein Becken
montiertes Gerät sicher installiert ist, bevor Sie es in Betrieb nehmen.
Lesen und befolgen Sie alle wichtigen Hinweise auf dem Gerät.
HINWEIS: Ein Kabel, das für eine geringere Ampere- oder Wattzahl als
