General notes

The sera KOI Professional 12000 Pond Filter is a multi-step purifica-

tion system designed according to newest current act filter technology

findings. The system is divided into the following steps.

Step 1: Highly effective, newly developed UV-C system (1.6)

• Reliable removal of all kinds of floating algae (cloudy, green water)

• Reduction of thread algae and other algae

• Lasting removal of pathogens and bacterial water cloudiness

The UV-C System was specially designed for garden pond purposes

and consistently developed using newest technology. The PL 55 W UV-C

lamp is operated by an electronic ballast. The UV-C system is therefore

particularly energy saving and economical.

Please refer to the information for use of the sera pond UV-C-System

55 W for further information.

Step 2: Mechanical water purification – sludge removal

The split sieve (1.2) removes all particles larger than 0.2 mm. The sieved

particles get into the waste water chamber (2.9) via the split sieve, and

thus are removed from the biological cycle of the pond. Particles

trapped in sponges or other media decompose slowly there and thus

are still available as a nutrient source for the biological community in the

pond.

They can be easily removed along with other remainders via the waste

water removal valve (1.15) of the waste water chamber (2.9). The residue

obtained this way can now unfold its valuable nutrients, e.g. as a gar-

den fertilizer.

Step 3: Oxygen enrichment (2.5)

The water falls through pond filter body underneath the split sieve (2.4)

where it is enriched with oxygen from the air by swirling. This allows

converting all substances that were not removed mechanically under

aerobic conditions within the following biological breakdown step.

Step 4: Fine mesh algae filtration (2.6)

The sera fine mesh filter sponge (1.3) can be placed underneath the

split sieve, as to keep the pond clear and attractive even in times of

strong floating algae growth. However, this measure should be taken

only for a limited time, mainly during summer. The kit includes two filter

sponges that should be used in an alternating way.

Step 5: Biological water purification (2.13)

The water is evenly distributed by a Matala mat above the biofilter

chamber after dirt and algae have been removed, and flows onto the

sera siporax pond filter medium below.

Due to its chemical and physical material properties, the high perform-

ance biofilter medium sera siporax pond provides an ideal living envi-

ronment for the valuable pollutant removing bio cultures. The open pore

structure ensures ideal water current conditions for the micro organ-

isms, thus ensuring the biofilms are optimally supplied and pores do not

get clogged even after years of operation. sera siporax pond biologi-

cally cleans itself! At the same time, sera siporax pond is very resistant

against wear and tear and thus allows operation times of several years.

The biological performance capacity is outstanding: A single liter (one

US quart) of sera siporax pond has the same breakdown performance

as approx. 34 liters (9 US gal.) of ceramic material. In other words: It

provides enormously high breakdown performance with very little space

requirements. Also, it requires very little maintenance and will last for a

long time!

SAFETY PRECAUTIONS

Attention electrical shock! All electrical units must be disconnected

from the mains/power supply before conducting work at the sera KOI

Professional 12000 Pond Filter, the UV-C lamp, the pond pump as well

as all other work in and around the pond.

Attention UV radiation! Do not look into the eye damaging light of the

UV-C lamp. Switch off the lamp before cleaning or maintenance.

Application and application range

The sera KOI Professional 12000 Pond Filter is designed for ponds

with high fish stock density, as is often the case with Koi ponds, with a

volume of up to 12,000 liters (3,170 US gal./h).

The latest technical alteration is a filter sponge chamber (2.7) that allows

inserting a fine mesh filter sponge (2.6) easily and conveniently without

any tools. The fine mesh filter sponge can be used in times of strong al-

gae blooms as to keep the pond water clear also during this time.

The special overflow chute (2.8) makes sure the sera KOI Professional

12000 Pond Filter cannot clog even in case of a very dirty fine mesh fil-

ter sponge.

It is important that the fine mesh filter sponge is cleaned daily, as to re-

move trapped nutrients contained in algae and floating matter, from the

pond permanently.

The fine mesh filter sponge should be removed from the sera KOI Pro-

fessional 12000 Pond Filter when the water is clear again. The fine

mesh filter sponge is dimensioned in a way that it can be easily washed

out and cleaned by hand under running water.

Also, the waste water chamber (2.9) underneath the split sieve should

be checked regularly and cleaned if necessary.

Kit includes Item no.

Assembly and operation

Complete every step (1. – 6.).

1. Location

The sera KOI Professional 12000 Pond Filter must be placed on one

level with the pond surface in a flat, horizontal position, allowing the wa-

ter to run back directly from the filter into the pond without water push-

ing back or counter pressure. Only a hose with max. 2 m (6.6 ft.) length

and the same diameter as the outlet may be connected to the filter out-

let (2.16). An artificial brook is suitable for directing the purified water

back into the pond in case you wish to place the filter in some distance

to the pond.

The position of the sera KOI Professional 12000 Pond Filter should be

chosen in a way that prevents knocking over the filter by pets, playing

children or the like.

The sera KOI Professional 12000 Pond Filter is not suitable for indoor

use.

2. Connection to pump

Check the diameter of your current hoses to the smallest diameter of the

hose connector. Smaller sections of the connector can be trimmed-

back with an (iron) saw to allow better flow with larger diameter hoses.

Before installing the hose connectors, always grease both O-rings with

the silicon oil included with the kit. Only then you may push them into

the opening up to the stop and fasten the screw cap.

For further information about putting sera pond pump PP 12000 or an-

other suitable pond pump in operation, please refer to the instructions

for use of the respective unit.

3. Connecting a sera pond UV-C System 55 W

You will find a detailed description about how to install the sera pond

UV-C System 55 W (1.6) to the sera KOI Professional 12000 Pond Fil-

ter in the information for use of the sera pond UV-C System 55 W.

4. Connecting the waste water removal valve (1.15)

If the waste water removal valve (2.10) is not yet installed at the side of

the split sieve (2.4), connect it with both seal rings, as shown in fig. 3.

You can screw the waste water removal valve (2.10) clockwise into its

counterpart held on the inside for this purpose. Screwing it on by hand

is sufficient. Fill the waste water chamber (2.9) with water underneath

the split sieve and check whether the waste water removal valve is wa-

ter proof.

5. Function control of the UV-C system: Wear protecting goggles

Please refer to the instructions for use of the sera pond UV-C System

55 W for this task.

6. Test run in case of connecting a UV-C system

Carry out a test run after having finished items 1 – 4.

Prior to using the sera pond UV-C-System 55 W, the fully installed unit

must be operated under normal operation conditions as expected later

on for at least 24 hours WITHOUT CONNECTING THE UV-C SYSTEM

TO THE POWER/MAINS SUPPLY, i.e. in simple flow operation connect-

ed to a pump, as to discover possible leaks in advance.

The water flow and pressure (pumping height) should match that of nor-

mal operation. Please refer to the instructions for use of the UV-C unit

for further information.

Maintenance and cleaning

a) Cleaning the split sieve

• Disconnect all electrical components from the mains/power supply

(UV-C system, pump, etc.) in and around the pond. Take off the cov-

er of the filter casing (aside the sera pond UV-C System 55 W).

• Place an empty bucket within reach. Remove all collected dirt and

sludge from the filter casing, preferably with water proof gloves.

• Now take out the split sieve (2.4). Wash the split sieve on both sides

using a hose. Particles stuck in the splits can carefully be removed

with a scrubbing brush. Do not use a wire brush or hard items to clean

the split sieve. The splits must not be damaged as to prevent the op-

timal purification effect of the sieve from being affected.

• Put the split sieve back into its holder after cleansing, the “arrow”

mark located at the bottom, i.e. in flow direction. The split sieve lifter

is simply placed on the top right or left. Put the filter chamber cover

(1.1) back on.

b) Cleansing the sera fine mesh filter sponge (2.6)

The sera fine mesh filter sponge must be washed out regularly and

thoroughly during periods of strong algae growth. Depending on the in-

tensity of floating algae growth, this may be required daily as to main-

tain the full purification performance of the pond filter system. In times

of low floating algae pollution, the pond filter should be operated with-

out the sera fine mesh filter sponge. The specially developed overflow

system provides efficient protection against the filter overflowing in case

you forgot washing out the sera fine mesh filter sponge.

c) Cleaning the Matala mat (2.11) and the bio chamber (2.13)

• Disconnect all electrical components from the mains/power supply

(UV system, pump, etc.) in and around the pond by pulling the mains

plug. Empty the upper part (1.4) [approx. 20 l (5.3 US gal.)], by loos-

ening the union nut between the UV-C system and the pond filter. Lift

the upper part of the filter casing (1.4) off the bottom part (1.10). Place

the upper part onto a plain surface and avoid knocking over the up-

per part. Be sure not to place the upper part on the cable connections

of the UV-C 55 W system or damage the UV-C 55 W system other-

wise.

• Now take the cover of the bottom part (1.7) off. Remove the Matala

mat (2.11). Rinse the Matala mat with a hose against the flow direc-

tion in the filter.

• The bio chamber (2.13) with sera siporax pond (2.14) is located un-

derneath the Matala mat. Remove the net and rinse it in a bucket with

lukewarm water. Do not use any detergents as to prevent the bacte -

rial flora from being destroyed. Only surface sludge must be removed

from sera siporax pond. The clear water chamber upstream of the

outlet opening (2.16) must remain free.

• Wipe out the empty bio chamber (2.13) with a soft sponge and rinse

it with water. Put sera siporax pond and the Matala mat back in

place. Put the upper part of the sera KOI Professional 12000 Pond

Filter back onto the bio chamber after cleansing. Switch on the pump

and put the UV-C system back into operation after 30 minutes.

SAFETY PRECAUTIONS

Warning: Dangerous ultraviolet radiation!

Never look directly into the special UV-C lighting (lamp) when it is operat -

ing (eye damage!).

Lamp function control through the two viewing glass panes at the top of

the UV-C casing or through the hose nozzle: Goggles (UV-C protecting

glass) provides suitable additional protection.

• The special sera UV-C lamp may be operated only inside the com-

pletely assembled sera pond UV-C System (please refer to direc-

tions for use for information about readiness to use). Every other use

may lead to severe skin and eye damage!

• Always keep UV units and UV-C lamps out of the reach of children!

• All electrical units in and around the pond must be disconnected from

the power/mains supply before conducting work at/in the pond and

on the sera KOI Professional 12000 Pond Filter.

• Operate unit only with an inserted fault current protection switch

(RCD or FI with a trip current of 30 mA).

• Do not operate if unit is submerged!

• Usage in or at swimming pools, walk-in ponds or swimming ponds is

not permitted!

• Never operate the UV-C system without water flow! First connect the

sera KOI Professional 12000 Pond Filter to a pump as described in

the instructions for use.

• For stabilizing its standing it may only be operated when the bottom

chamber is sufficiently filled, e.g. with sera siporax pond.

• Ensure that there is sufficient water flow through the sera pond UV-C

System before switching on the UV-C lamp. A minimum flow rate of

at least 2,000 l/h (530 US gal./h) up to 12,000 l/h (3,170 US gal./h) at

the maximum must be ensured also during operation.

• At the first sign of frost, disconnect and drain the sera pond UV-C

System, and store in a frost-free location (without water or water re-

mainders). We recommend thorough cleaning before winter storage.

• Frequent “ON/OFF” switching reduces the life expectancy of the UV-C

lamp.

• Ensure that the electrical plug of the switched-on unit is freely acces-

sible at all times.

• The test run according to the section “Assembly and operation” must

be carried out before putting the UV-C system into operation!

Also observe all safety advice provided in the instructions for use of the

included devices.

Cloudiness is not caused by algae but by

mineral particles (e.g., clay/loam components),

or humic substances (e.g., from leaves). Milky

white cloudiness can be caused by micro

organisms that require much stronger UV

irradiation to destroy them (occasionally

apparent after disease treatments).

In case cloudiness is not successfully

removed, the cause is often that the filter

material has been cleaned too frequently.
