Important instructions
• The use of lter systems for swimming pools
and their protected areas is only permitted if
they are designed and constructed in accor-
dance with VDE 0100-49D. It is mandatory to
protect the power connection via an residual
leakage circuit breaker.
• In order to maintain the required protected
area (removal of electronic equipment from
water), the lter system must be positioned
outside the water with a minimum distance
of 3 m. (Protected area 2 according to VDE
0100-702.)
• Further safety instructions can be found in
the enclosed operating instructions for the
pump. These must be observed! (The CE
label is also included).
To avoid damage:
• Never let the pump run dry (the lter system
must be installed and the suction hose
lled with water before commissioning).
The connection to the pool skimmer and to
the inlet nozzle must be completed before
commissioning.
• Actuate the 6-way valve only when the pump
is switched off!
• Filter systems with non-self-priming pump
must be installed below the water level.

1. FILTER SYSTEM – DESCRIPTION
The sand lter system you have
purchased is a high-quality quality
product. We hope you will enjoy your
swimming pool and the lter system.
We recommend that you read these assembly
instructions and the enclosed operating instructions
for the pump carefully. Keep them in a safe place
and familiarize yourself with the special features
and possible uses of this system. The lter system
ensures a mechanical treatment of swimming pool
water. However, an impeccable water quality can
only be guaranteed if the water is treated chemically
in addition (see information on reverse side).
1.1 DESCRIPTION OF 6-WAY VALVE
The individual functions/positions of the plastic
valve are clearly marked on the upper side so that
there is no risk of confusion. Please also observe
the drawings and explanations in our Quick
Start Guide on page 5.
1.1.1 FILTER:
Filtration (operating state)
In this position, the swimming pool water is
pumped through the lter tank and quartz sand
and then back to the pool. The dirt is ltered
out via the quartz sand.
1.1.2 Closed:
Servicing
All functions are disabled in this position. The
circulation pump must not be switched on. This
position is used when maintenance works are
carried out in the lter tank.
1.1.3 Backwash:
CLEANING THE Filter system
In this position, the swimming pool water
is pumped through the lter in the opposite
direction (from bottom to top) to clean it. The
waste water is drained sideways out of the
valve (hose outlet = waste).
1.1.4 Recirculate:
Circulate without ltration
(increased circulation)
In this position, the swimming pool water ows
right into the swimming pool, the lter tank is
bypassed. This setting is used after adding
pool chemicals (e.g. after a shock chlorinati-
on).
1.1.5 RINSE:
Filtration into the sewer
In this position, the lines of the lter system are
cleaned from residual dirt after backwashing.
1.1.6 Waste:
Emptying/Sewer
In this position, the swimming pool water is
pumped directly into the sewer (valve outlet
‚Waste‘).

1.2 DESCRIPTION OF CIRCULATION PUMP
The circulation pump is used to pump the water from the swimming pool through the lter tank and back into
the swimming pool (see also enclosed separate pump manual).
1.2.2 SHAFT SEAL
The pump is equipped with a mechanical seal bet-
ween the pump housing and the motor to seal the
motor shaft. This seal is a wearing part/no warranty
(see pump 4.2.3).
1.3 DESCRIPTION OF FILTER TANK
The lter tank is used to mechanically remove
suspended particles such as hair, skin akes, pollen
and other impurities from the swimming pool water
by means of a special quartz sand for swimming
pools (0.4 - 0.8 mm or other lter medium, e.g. lter
glass or lter balls). This is done at a pressure of
0.4 - 0.8 bar. When the pressure increases (loud
pumping noise) the lter must be backwashed (see
section 2.4). This is by no means a defect of the
pump, it is a normal process, as the pump has to
work against a higher resistance if the lter tank/
lter sand is too dirty. To measure the lter pressure
in the tank, there is an optional pressure gauge
(item no.: 2600020) available (not included in deli-
very), which is xed at the top of the valve (bleeder
screw). The pressure gauge allows you to read
the lter pressure at any time and thus determine
whether a backwashing is required. If you do not
have or use a pressure gauge, we recommend
backwashing once a week.

2. INSTALLATION OF SAND FILTER SYSTEM
Step 1:
The following tools are required for this: Phillips
screwdriver, Teon tape, 7 mm wrench, possibly
drill, possibly cordless screwdriver, rubber hammer.
Step 2:
Insert the drain valve into the pre-drilled hole on the
lter tank, i.e. from the inside to the outside. While
doing so, please mount a rubber seal each from the
inside and from the outside and then x the drain
valve with the lock nut from the outside.
Step 3: (Instructions for model with riser pipe 1)
At rst, screw only 2 of the lter cartridges into the
riser pipe.
Step 4: (Instructions for model with riser pipe 1)
The other lter cartridges are inserted in the tank,
as otherwise the assembled riser pipe would not t
through the tank opening.
Step 5: (Instructions for model with riser pipe 2)
If you use our alternative tank with xed (glued) lter
basket, it is simply inserted into the lter tank.

Assembly and Operating Instructions Sand Filter System without Pre-lter
English
13
Step 6:
Before lling the quartz sand in, close the top of the
riser pipe with a plastic bag to prevent sand from
entering the riser pipe.
Step 7:
Please select the correct quartz sand grain size (0.4
- 0.8 mm) for your lter system, as otherwise there
may be problems during the lter operation.
Step 8:
Carefully ll the correct amount of quartz sand (see
table) in from the top into the lter tank, and ensure
that the riser pipe remains in the correct central
position. About two-thirds of the lter tank should be
lled with quartz sand.
Step 9:
Next place the O-ring on the valve from below.
Step 10:
Please ensure that the clamping ring and the screws
are mounted/assembled correctly, i.e. in the right
direction. You can see the correct way on the photo:
The nut of the screw also
grips into the groove of
the clamping ring to hold
the nut in place.

Assembly and Operating Instructions Sand Filter System without Pre-lter
14
English
Step 11:
If necessary, loosen the clamping ring carefully
using a rubber hammer to achieve a better sealing
and a uniform tensioning of the clamping ring.
Step 12: Only with 2260140 and 2260148 pump
Insert the rubber hose tting (only included with
2260140 and 2260148 pump) into the connecting
hose and insert in on the upper pump connection
(as far as possible). Then x it rmly with a hose
clip.
Step 13:
Fasten the hose to the middle hose connection
(labeled ‚Pump‘) on the top of the valve.
Step 14:
Fix the lter pump on the lter pallet using the
self-tapping screws.
Step 15:
If the hose connections do not seal well, you can
use Teon tape for additional sealing. To do this,
wrap at least 15 times.

Assembly and Operating Instructions Sand Filter System without Pre-lter
English
15
Step 16:
The hose is attached to the suction side of the
pump, which runs to the swimming pool skimmer.
Step 17:
The return hose to the inlet nozzle is connected to
the ‚Return‘ hose connection via the valve.
Step 18:
On the right-hand side of the valve, you can nd the
hose connection for backwashing (dirty water into
the drains). This is labeled ‚Waste‘.
2.3 FILLING WATER IN - COMMISSIONING THE FILTER
2.3.1 INSTALLATION WITH BUILT-IN SKIMMER
After the swimming pool has been lled with
water up to at least the middle of the surface
skimmer, the water automatically runs into
the pump. If necessary, we recommend the
installation of a gate valve in addition. It can
be used to interrupt the water ow of the lter
system.
2.3.2 SYSTEM WITH SUSPENSION SKIMMER
Before the suction hose is connected to the
skimmer, it must rst be completely lled with
water.
2.3.3 FRAME POOL OR QUICK UP POOL
Please connect the suction hose and also the
return hose to the two hose ttings of the pool.
We recommend to install a suitable skimmer
offered by the pool manufacturer in addition.
This is usually connected with a separate
hose from the inside of the pool.
In no case should the 2 hoses simply hang
into the water and the lter system be installed
without a skimmer. This can and will not work
and there is a risk of irreparable damage to the
lter system/pump.

2.4 RINSING THE QUARTZ SAND
(BEFORE COMMISSIONING)
Set the hand lever of the 6-way valve to the RINSE
position, switch the lter system on electrically. In
case of very long suction lines, it can take up to 2-3
minutes until the swimming pool water is pumped.
After water starts to be pumped, drain the water into
the sewage system for about 1 minute to prevent an
abrasion of quartz sand from entering the swimming
pool via the inlet nozzle. Then set the valve to
“Rinse” for 30 seconds (see also section 3.2).
Warning! Please operate the 6-way
valve only when the lter pump is
switched off.
Otherwise there is a danger of destroying
the 6-way valve!
2.5 FILTER – OPERATION
Set the hand lever of the 6-way valve to FILTER.
The quartz sand lter for a mechanical water
treatment of your swimming pool is now ready for
operation. Switch the lter system on.
2.6 SETTING THE FILTRATION TIME
The operating time of the quartz sand lter depends
on swimming pool size (water volume), bather load,
weather and the used chemicals.
Example: It is recommended to recirculate the
pool volume 1 to 1.5 times in 24 hours.
If a pool volume of 10 m³ is circulated 1.5 times, a
total of 15 m³ must be circulated. If the pump has
an output of 6 m³ per hour, the operating time of the
lter is approx. 2.5 hours. To achieve an optimal
mechanical cleaning, the lter should be running
without interruption during this time.
Attention: On hot days, the lter time must be
increased to ensure a sufcient disinfection.
(Example: 2 hours in the morning and 2 hours in the
afternoon.) The lter system must also be switched
on on rainy days, as organic impurities get into the
swimming pool via the rainwater, which promotes
algae growth!
2.7 CONNECTING THE SAND FILTER
SYSTEM TO THE POOL
A connecting hose to the skimmer of your pool
(where the dirty water is drawn in) is laid on the suc-
tion side of the pump (horizontal hose connection).
The cleaned water is fed back into the pool via a
connecting hose between the valve of your lter sys-
tem (the valve has 3 black hose adapters which are
labeled as follows: Return, Waste and Pump) and
the hose adapter labeled ‘Return’.

3. REGULAR BACKWASHING
Clean the lter (backwashing) once a week.
To be able to determine when to carry out a lter
cleaning (BACKWAHING), we recommend to use a
pressure gauge. Systems with pressure gauge allow
reading the pressure off the gauge. If the pressure
increases by 0.3 bar (max. 0.6 bar), a backwashing
must be carried out. A weekly backwashing of
the lter is recommended, even if this value is not
reached. This ensures that the lter sand remains
loose and does not stick together. Pressure gauges
for our lter system are available separately (article
no.: 2600020). Please contact your dealer, if
required.
Attention: Rell the missing water
level in the pool with fresh water after
backwashing!
3.1 BACKWASHING
Set the 6-way valve to BACKWASH.
Switch the lter system on. When the pumped water
is clean, the backwashing process is completed,
which should take 3 minutes at the most.
Set the 6-way valve to FILTER or RINSE (switch the
power supply off rst).
3.2 RINSE
The 6-way valve optionally also allows draining
parts of the residual dirt after backwashing into the
sewer system instead of the swimming pool.
To do this, set the 6-way valve to RINSE. Switch the
lter system on for a maximum of 30 seconds, then
reset the 6-way valve to FILTER.
4. MAINTENANCE WORKS
4.1 MAINTENANCE OF FILTER TANK
The gate valves must be closed during mainte-
nance works and be reopened after completion of
these works.
The ll level and condition of the quartz sand must
be checked once a year. The sand must ow loosely
through the hand! If lumps are formed, the quartz
sand must be replaced completely. See Section 2.2
‘Filling’.
4.2 MAINTENANCE OF CIRCULATION PUMP
Switch the pump off, set the 6-way valve to
CLOSED. Observe point 1.1.2! In the winter, empty
the pump completely and store it in a frost-free
place; turn the motor shaft occasionally to prevent
the shaft from becoming encrusted by limescale
deposits.
4.2.1 MOUNTINGS
The two engine mounts are self-lubricating
and do not require maintenance.
4.2.2 SHAFT SEAL
The shaft is equipped with a mechanical seal
which may leak after prolonged operation. We
recommend purchasing a new pump when
this happens.
4.2.3 MOTOR
No special maintenance required.
4.2.5 MAINTENANCE OF 6-WAY VALVE
This valve is maintenance-free. It is impor-
tant, however, that the pump is always rst
switched off before changing the position.

4.3 GENERAL MAINTENANCE
• The swimming pool must be maintained and
serviced in accordance with the manufacturer’s
instructions.
• The skimmer strainer in the surface skimmer
must be cleaned regularly at short intervals.
• It is important to ensure that the water level in the
pool never falls below the middle of the skimmer
at least (minimum lling level).
5. TAKING OUT OF OPERATION
• The swimming pool must be winterized in accord-
ance with the relevant instructions of the pool
manufacturer.
• The lter system must be winterized if there is a
risk of frost. The following should be observed:
Drain the water from the lter tank through the
drain plug at the bottom of the lter tank.
• The pipes from and to the swimming pool must
be emptied completely.
• Switch off the power supply (set to 0), unplug the
earthed plug (Schuko).
• Remove the quartz sand from the lter tank and
store the entire lter system in a frost-protected
area (e.g. in the basement). Do not push or
transport the lled tank, otherwise there is a risk
of breakage.
6. TROUBLESHOOTING
6.1 PUMP DOES NOT DRAW IN WATER
AUTOMATICALLY OR THE PRIMING
TAKES VERY LONG
1. Check the suction line for leaks, as air is drawn in
if the line is leaking.
2. Check the water level in the pool. If the water
level in the skimmer is too low, the pump also
draws in air. Fill water in (increase water level) up
to the middle of the skimmer port.
3. Check whether the skimmer ap can be moved
easily and does no jam. Otherwise, the pump pri-
ming will be poor or the water column will always
break down. This can damage the pump.
4. Check whether the strainer basket in the skimmer
is clean, if necessary clean the strainer basket.
5. Check whether the gate valves in the suction and
pressures pipes are open.
6.2 INSUFFICIENT PERFORMANCE OF
CIRCULATION PUMP
1. Filter is dirty; it must be backwashed.
2. Gate valves in the system are not fully open.
3. Skimmer basket in skimmer dirty? Cleaning required.
4. Suction line leaking, pump draws air in.

6.3 CIRCULATION PUMP IS TOO NOISY
1. Filter is dirty; it must be backwashed.
2. Remove foreign particles from the pump, unscrew
pump housing, clean housing and impeller.
3. Motor bearings are too noisy, replace the entire
motor complete with impeller.
4. The pump is standing on a bare wood oor or
concrete oor, resulting in a sound transmission
to the building (structure-borne sound). Place the
pump on a noise-damping insulating base (rubber,
cork, etc.).
6.4 CIRCULATION PUMP
DOES NOT START AUTOMATICALLY
1. Check whether the power line is live.
2. Check if the fuse is defective.
3. For AC pumps, check whether the capacitor is in
proper working order.
4. Check that the motor is in proper working order;
have the winding checked by an electrician.
5. Check whether the pump has got stuck (motor
shaft can be turned easily with a screwdriver, other-
wise see 6.4). Attention: Carry out only after the
mains plug has been disconnected! Risk of injury!
Check whether the motor-protective circuit-brea-
ker has been tripped; if so see point 6.2.
6.5 WATER DRIPPING FROM CIRCULATI-
ON PUMP BETWEEN PUMP HOUSING
AND MOTOR
1. During commissioning, it is possible that water
escapes in drops at intervals of approx. 2 minutes.
After a few hours of operation, when the seal has
run in, the dripping stops automatically.
2. If water is constantly leaking from this point, the
mechanical seal is defective.
6.6 QUARTZ SAND IS FLUSHED OUT OF
THE FILTER INTO THE POOL
1. Incorrect grain size (too ne). Special quartz
sand granulation 0.4 - 0.8 mm required.
2. Filter base in lter container damaged - replace
lter base.
3. 6-way valve damaged or dirty - replace/clean.
6.7 FILTER PRESSURE AT THE PRESSU-
RE GAUGE DOES NOT DROP BACK
TO INITIAL PRESSURE AFTER BACK-
WASHING, OR INITIAL PRESSURE IS
TOO HIGH
1. Pressure gauge defective - replace.
2. Quartz sand hardened and/or clumped - lter sand
must be replaced.
3. Suction or pressure line too small or valve closed.
6.8 WATER IS NOT CLEAR
1. Insufcient disinfection (chlorination), which cau-
ses an overload of the lter; check and adjust
chlorine and pH value in respect of specied
values.
2. Filter is too small.
3. Circulation time is too short.
4. If necessary, use occulant for quartz sand lters.
5. Insufcient lter backwashing operations cause
short lter run times.
6.9 SWIMMING POOL LOSES WATER VIA
THE FILTER SYSTEM
1. Gaskets in 6-way valve damaged - replace.
2. Feed pipe from swimming pool is leaking.
