External Protein Skimmer MCE 601
Operating Instructions
The Multi Compact External skimmer is ideal for 'hang on' installation directly onto the outside of the aquarium
or sump and requires no further supply pump for highly efficient operation.
Assembly
The skimmer has been packed in a partially disassembled state to prevent damage in transit. Do not switch on
the recirculation pump however unless the pump is immersed or flooded with water.
Important
Before you install the unit in position fill the body with fresh water from the mains supply to ensure that there
has not been any damage in transit.
Installation
Hang the skimmer body on the outside of the aquarium in a suitable position. The skimmer sits on the black
support bar where the outlet pipes come out of the body and is held in place by the clear retaining clamp,
which tightens onto the outlet pipe Hang the skimmer body on the outside of the aquarium in a suitable
position. The inlet pipe is fitted with a strainer on one end, which simply pulls off for future cleaning. The
outlet pipe consists of a 40mm clear pipe to direct water back over any stress bars and into the tank. To
prevent bubbles from entering the aquarium an ingenious degassing plate pushes into the end of the outlet
pipe.
Operation and setting
With the unit secured in position, fill the body with tank water by removing the skimmer cup and pouring
water down the opening until the water exits the skimmer. Refit the cup, initially positioned quite high out of
the body close the tap on the air intake pipe, only now fit the inlet pipe and switch on the pump on stage 4
(controller). Open the air intake tap and set it to the 12 o'clock position. The body of the skimmer should now
be white with fine dense foam. Leave the skimmer to settle down for a day or so before fine adjustment. After
two to three days, or earlier in a previously unskimmed tank, a thick drown foam will be produced at the neck
of the skimmer. Move the skimmer cup up or down to collect this foam. Moving the cup downwards will result
in an increased quantity of wetter foam and moving it up a darker, foam which is preferable. It is
recommended that the skimmer cup is emptied every 2-4 days or as required. The cup should be wiped clean
of any fatty deposits as build up of this waste product will greatly reduce the performance. Whilst cleaning
leave the pump switched off, for 15 minutes to allow any salt deposits in the venturi tube to dissolve.
Please Note
The skimmer cup is reversible by 180° so that, depending on the mounting position of the skimmer, the clear
side is always visible.
Media Chamber
The chamber below the outlet pipe has been provided to allow the addition of media such as Deltec
Phosphatadsorber, Deltec Special Carbon or biological media to be used easily and effectively in a position of
good flow. Media used in this chamber must be contained in a bag to prevent carry over back to the aquarium.
To prevent the bag from floating up and blocking the outlet pipe, the skimmer comes as standard with a
sliding outlet protection plate, which must be fitted at any time that media is used in the unit.
This plate is fitted above the media bag with the horizontal section at its lowest point.
Optional Media Box with sliding lid
This item is available as an optional extra to allow use of the multi compact with a greater volume of media.
Larger media can be added directly to the box, which has a perforated base and a perforated sliding lid. Finer
media can be used by the addition of sponge top and bottom to prevent the media from washing out or by use
of a mesh bag.
Use with ozone
skimmers are suitable for use with ozone and will automatically suck the gas through the venturi
hose. A maximum volume of 25 mg/h should be used on tank volumes that are suitable for this skimmer. Do
not use excessive ozone, as it is dangerous and can cause severe headaches.
Maintenance
The skimmer range should require very little adjustment and maintenance due to the high levels of
calcium in marine aquariums and large volumes of air drawn in, it is common for deposits to accumulate.
Regular introduction of a small amount of RO water into the inlet tap whilst running may help to prevent any
build up of salt and debris in the venturi.
The MCE 601 is fitted with an electronically controllable 24V DC pump. It is recommended every 3 months to
strip down the pump to check and clean the impellor of debris.
