1. GENERAL
You have made a far-sighted, economical and practical choice with our stainless steel swimming pool.
The material stainless steel has proven itself over decades. It is the most resistant, durable and efficient
material in the modern technology of bathroom construction.
In order to be able to guarantee you a problem-free and easy-care maintenance of your stainless steel
swimming pool, we ask you to observe and follow the following care and operating instructions exactly.
We cannot assume any warranty for damage resulting from disregard of our operating
instructions!
The operation and maintenance of a swimming pool requires a multitude of specific chemical processes.
In order to prevent undesirable side effects, before using chemical products you should observe their
composition, the corresponding safety instructions, safety data sheets and the protection regulations
according to the GUV in their respective valid version.
If you read this manual carefully, you may get the impression that the maintenance of a stainless steel
swimming pool is a "science". Exactly the opposite is the case, it is certainly by far the easiest to maintain
swimming pool.
With this operating and maintenance manual, however, we want to address all questions that may arise
in order to provide you and your operating personnel with a comprehensive guide.

2. CHEMICAL RESISTANCE
2.1. technical room, filter room
In case open filters or gushing water tanks are used in connection with stainless steel pools, the following
must be observed: A common air space of open filters, open splash water tanks with the outside of the
pool is to be avoided at all costs, as a concentration of chlorides contained in the atmosphere will
cause lasting damage to the pool.
If constructional constraints do not allow a local separation, the required condition shall be achieved by
installing a partition wall or by covering these containers as tightly as possible. A sufficient forced
ventilation and venting to the outside reduces the probability of corrosion.
2.2. Filled basin
For the material stainless steel no coating is required as corrosion protection. Stainless steel has an
invisible passive layer, which is mainly formed by the alloying element chromium in combination with
oxygen, and is therefore resistant to corrosion. If the passive layer is damaged, it rebuilds automatically
under the influence of oxygen.
Under normal operating conditions, high-alloy steel is completely resistant to most water. As is the case
with any material, there are certain limits to the use of stainless steel. Under special influences or
conditions (e.g. filling water highly contaminated with chlorides, water treatment plants not conforming
to standards), special tests are required for the choice of material.
In this regard, we refer to the standards and legal regulations concerning the "Treatment and
disinfection of swimming and bathing pool water" (Germany: DIN 19643, Austria: Austrian bathing
hygiene law no. 254/1976 in the currently valid version, ÖNORM M 6215 to 6217, Switzerland: SIA 385/9)
as well as the permissible qualities of filling and pool water.
For chloride and sulphate contaminated filling water, we will advise you on the choice of material
based on the chemical water analysis provided by you.
 Special filling waters:
Special examinations are required for pools with sea water, mineral water and medicinal and
therapeutic pools. Special guidelines adapted to the respective material must be observed.
2.3. Limit values
The operation of the water treatment plant must be carried out in such a way that the following values
are maintained at the usual pool water temperature (max. 32°C) in the pool water:
TABLE 1

in Table 1 for compliance (pH value and free chlorine daily, chlorides every 3 weeks).
This must be done with approved and calibrated measuring instruments or with the aid of a laboratory for
water analysis.
In case of deviations, an immediate notification to our company is necessary in order to be able to avert
damage to the pool with appropriate measures.
If chloride concentrations are too high, an immediate, intensive water exchange is absolutely necessary,
which can be achieved by adding plenty of fresh water, e.g. after filter backwashing. Corrosion damage
to the pool - without proof of compliance with the permissible chloride concentration or pH value -
cannot be recognised as defects within the meaning of the warranty.
2.4. Note on water treatment
General:
The water treatment is carried out with the help of physical and chemical process steps.
In addition to disinfection, the generic term water treatment includes above all pH value regulation,
algae control, flocculation, filtration and also the addition of fresh water.
2.4.1. pH value correction
At pH values above or below the values given in Table 1, the disinfectant effect of chlorination is
impaired. In addition, undesirable side effects occur, especially if the pH value is too low, the material
resistance is negatively affected. A correction of the pH value - raising / lowering - is absolutely
necessary. Too high or too low a pH value can harm your bathing guest.
Lower pH value:
Under no circumstances may hydrofluoric acid or chloride-containing acids (such as hydrochloric acid)
be used.
This leads to the permissible chloride concentration being exceeded and subsequently to the destruction
of the material structure. Sulphuric acid, for example, is permissible.
Raise pH value:
This can be done by adding soda or caustic soda in liquid form.
2.4.2. Flocculants
Aluminium-based flocculants in liquid form are permitted.
Flocculants containing chloride should be avoided. In case of doubt, your inquiry (stating the chloride
content as well as the dosing quantity in relation to the circulation capacity) can help us to clarify the
matter.
2.4.3. Germicides
The continuous addition of chlorine-containing substances for disinfection until the values for free
chlorine listed in Table 1 on page 3 are reached is permitted.
Any addition of chlorine- or chloride-containing chemicals that are not used for disinfection is
prohibited, either continuously or intermittently.
2.4.4. Fresh water / chloride content
The fresh water addition of 30 litres per bathing guest per day, as provided for in the standards, is usually
suitable for meeting the limit values for chlorides.

MB_S21-050 version: 1.8
If this is not sufficient for reasons arising from ongoing operation, the fresh water addition must be
increased to such an extent that the chloride limit values are complied with.
Remember that high chloride levels damage all metal parts installed in the water circuit.
2.4.5. Algae Destruction
If a modern water treatment system is used, algae prevention/prevention agents are not required due to
the fact that the stainless steel pool has a non-porous surface and our pool hydraulics ensure excellent
distribution of pure water.
Algae destruction agents containing heavy metal salts, such as copper sulphate and those containing
silver or mercury, must not be used in stainless steel pools either. They are in any case questionable in
terms of sewage law.
Here, too, everything that harms the metals in your water cycle also harms your bathers.
Before using algaecides (= quaternary ammonium compounds), please contact your water rights
authority.
2.4.6. Introduction of chemicals
Chemicals may only be introduced into the pool in dissolved, diluted form via the clean water pipe,
whereby the addition must be made continuously into the clean water pipe, directly after the filters
(dosing system). Circulation must be maintained until 24 hours after the end of the addition of chemicals.
This guarantees an absolutely even mixing.
The direct addition of chemicals directly into the pool is generally prohibited.
The desired qualitative condition of the pool water - depending on the pure and raw water - can often
be positively influenced by minor changes in the process or in the choice of chemicals.
In case of doubt, we will be happy to advise you and help you find the best solution for your specific
case. Please contact us in confidence.

3. CARE AND MAINTENANCE
3.1. corner discharge
We recommend an annual emptying of all basins to remove deposits and possible corrosion (e.g. by
overlooked coins etc.), as well as to check all screwed components under water.
The period between emptying the tank and filling it should be kept as short as possible, i.e. only the
actual cleaning and maintenance time should be limited.
Special attention should be paid to this:
3.1.1. Flood
Since floods can occur at different speeds and it is not certain that existing safety devices such as
groundwater lowering and flood valves in their dimensioning can adequately protect the basin from
the amount of water that occurs, the basin must be secured by filling it to the overflow edge in the
event of impending flooding.
3.1.2. Groundwater
The maximum groundwater level to be expected must be at least 20 cm below the maximum basin
depth or be kept at this level by suitable groundwater lowering.
Flood valves are used to ensure the safety of the emptied basin in the event of failure of facilities for
lowering the groundwater table or if the groundwater level slowly rises.
3.1.3. Frost effects
The basin must not be emptied when the outside temperature is below 0°C. There is a risk of the pool
substructure (foundations, gravel bed) freezing up.
The tank must also be completely free of ice before emptying - risk of damage from ice floes!
3.1.4. Coverings
In order to make cleaning the pool as easy as possible, it is advantageous to rinse off visible deposits
with a strong water jet (pressure hose or high-pressure cleaner) while emptying the pool - especially in
the floor area - to prevent algae, rotten leaves etc. from drying up.
3.2. Pool cleaning
3.2.1. Principles of pool cleaning
 Sharp tools, grindstones, wire brushes, files, steel wool made of unalloyed or low-alloyed carbon
steel, etc. must not be used for cleaning chrome-nickel steel.
Consequence of disregard: friction marks, scratches, dull areas as well as external rust formation.
 Metallic hose couplings should be wrapped with a cloth to avoid scratch marks and extraneous rust.
 All tools, screws, bolts, pipe sections and the like must be removed from the pool after cleaning.
 Consequences if disregarded: formation of extraneous rust, corrosion.
 Metallic parts such as hair clips, coins, etc., which have remained in the pool over the winter, are in
most cases corroded and have left rust stains (pool bottom, gushing water channel, bench,
whirlpool bed, ... ). These must be removed by pickling. The staining paste must not dry up and must
be washed off with a water jet and a cloth or soft brush to avoid staining.
When processing the chemical cleaning agents mentioned in point 3.2.5. below, care must be taken to
ensure that they do not dry up under any circumstances. The result would be an unsightly stain.

Depending on the water depth, the tank emptying should be kept closed as long as possible during the
cleaning process in order to dilute the washed chemicals on the one hand and to achieve an effective
neutralisation on the other hand before the cleaning residues are added to the waste water.
The swimming strips in the middle of the lanes may only be cleaned with neutral, mild, non-abrasive
cleaning agents. When using a high-pressure cleaner, the pressure must be kept low (max. 50 bar, water
temperature max. 30°C).
The cleaning of your stainless steel pool must of course also include all ancillary areas such as the
expansion tank, floor channel, overflow channel, etc.
Cleaning of floor duct and floor duct cover:
To clean the floor duct, the floor duct covers must be completely removed. Cleaning is carried out with
commercially available stainless steel cleaners as described in 3.2.5.
Notes on cleaning the rubber seals:
 Avoid contact with strongly acidic, alkaline, oxidative and fatty cleaning agents, which are also
intended for stainless steel.
 Contact with organic, non-polar solvents (turpentine, petrol, etc.) must be strictly avoided in both
pure and mixed forms (emulsion cleaner).
 Most water-based neutral cleaners (surfactants, dishwashing detergents) are suitable as cleaning
agents. These should only be used in diluted form.
 The rubber is temperature resistant even in hot water. Accordingly, the use of warm water (up to 80
°C) with a cleaning agent described above using a sponge / plastic fleece (without roughened
side) is very suitable for cleaning the seals.
When cleaning the floor trunking covers, first clean the rubber seals according to the above instructions.
To clean the stainless steel surface of the floor duct cover, the stainless steel cleaner must be applied with
a brush in such a way that it does not come into contact with the rubber seal. After the stainless steel
cleaner has soaked in water, rinse with plenty of water and make sure that the rubber seal is rinsed off
extra thoroughly.
When reinstalling the floor duct covers, ensure that the seals are fully seated and that the sealing lips are
clean.
When the floor trunking lid is pushed into the lock, the rear sealing lip tends to turn over, so the use of a
lubricant and care product for rubber seals is recommended. Check the correct position of the sealing
lip. The sealing lips must be directed inwards from the outer edge of the cover.
This applies analogously to the maintenance of flood valves.
The lid of the flooding valve opens automatically at a water level of 10 cm above lid level. To ensure
this, clean the seat of the seal and the seal itself and coat the seal with glycerine. An unclean seal or an
eccentric seat of the inserted flood valve cover could be the cause of permanent and considerable
water loss over time.
Under no circumstances should pool cleaning with chemicals be carried out under intensive sunlight and
thus in excessively heated pools, as the chemical processes that take place have much shorter reaction
times depending on the temperature, and therefore undesirable side effects (burns, staining, etc.) can
occur if these are not observed.
To prevent dry spots on the bottom of the pool, experienced swimming supervisors use sprinklers between
cleaning and filling.
The water used in this way also serves to further dilute the cleaning agents.
3.2.2. Gutter cover grids
When cleaning the basin with nitric acid, the channel cover grids must be removed. The grates may only
be cleaned with phosphorous-based cleaners (max. concentration 5%). Afterwards, they must be

lye or hydrochloric acid are generally prohibited for cleaning.
3.2.3. Equipment parts
Plastic equipment shall be cleaned with neutral detergent (such as dishwashing detergent or similar) and
scratch-free cloths.
For mechanical cleaning, we recommend the use of a high-pressure cleaner.
Stainless steel equipment parts are to be cleaned in the same way as the basins themselves.
On the following pages we give you hints and recommendations for cleaning various types of dirt:

Miscellaneous Natural leather (chamois leather),
artificial leather, artificial fleece,
sponges, sponge cloths.
3.2.5. Chemical cleaning agents
Must be free of halogens (chloride and fluoride ions), i.e. they must not contain hydrochloric acid,
hydrofluoric acid, sodium hypochlorite or calcium hypochlorite. Such ingredients have a damaging
effect on the surface and can lead to the destruction of the material structure.
Resources Composition Fields of application
All-purpose cleaner Surfactants, water, often with addition of
phosphates and ammonia solution.
Especially for light grease stains.
Neutral cleaner Surfactants, water and fragrances;
dishwashing detergent.
For surfaces contaminated with
grease and oil (fingerprints).
Alcohol cleaner Surfactants, alcohol, water and
fragrances.
Like all-purpose cleaner.
Alkaline cleaners Surfactants, water and alkali; water-
soluble organic solvents are often still
present.
Especially for heavy grease and
oil contamination (resinous oils).
Abrasive alkaline
cleaners
Surfactants, water and alkali; water-
soluble organic solvents are often still
present. As abrasive they contain fine
polishing agents (mostly slurry chalk). -
May only be used on the pool walls in the
grinding direction.
For all heavy grease stains and
deposits of mineral substances
(soot, rust, light water stains from
calcareous water). To be
effective, the polishing agents
must be harder than the dirt. To
avoid damaging the surface,
they must be softer than stainless
steel.
Solvent cleaner Usually a mixture of organic solvents; they
may be miscible with water (e.g. butyl
diglycol, diethylene glycol ether, alcohol)
or immiscible with water (petrol,
turpentine).
Depending on the type,
particularly good for removing
grease, oil, wax, tar, adhesives,
varnishes and paints.
Abrasion-free emulsion
cleaners
Surfactants, water, water-immiscible
organic solvents; often additional alkalis.
Especially for heavy grease
stains, waxes, tar, colours. Better
than scrub-free alkaline
cleaners, but worse than solvent
cleaners.
Abrasive emulsion
cleaners
Like non-abrasive emulsion cleaners, but
they contain polishing agents.
Like abrasive alkaline cleaners,
but better cleaning effect on
grease and tar.

Acidic cleaners Acid (e.g. phosphoric acid, nitric acid,
amidosulfonic acid, citric acid, acid-
resistant surfactants, water, possibly
fragrances).
Hydrochloric acid and/or cleaning
agents containing hydrochloric acid
must not be used. Due to the non-porous
nature of the surface of the stainless
steel, a depth effect is not possible and
therefore not necessary.
Removes soiling such as
limescale deposits, rust deposits,
grease-bound pigment dirt, light
grease stains. Acidic cleaners
may only be disposed of in the
appropriate dilution (e.g. 1:3 for
nitric acid/water) in agreement
with the competent authority.
Disinfectant cleaner Quaternary ammonium compounds (=
algicides) with added water (they act
as catonic surfactants and disinfect at
the same time) - aldehydes, surfactants
and water
Cleaners containing chlorine and/or
chloride, such as sodium hypochlorite,
must not be used. Due to the non-
porous nature of the surface of the
stainless steel, a depth effect is not
possible and therefore not necessary.
Effect on pathogenic germs
varies - depending on the
disinfecting agent. When using
disinfectant cleaners of any
kind, agreement must be
reached with the responsible
authority (water authority,
person authorised to fish, etc.).
Cleaning agent for
high pressure cleaners
Alkaline, neutral or acidic agents (see
relevant section); depending on the
application, they are set to be low-
foaming or high-foaming.
High-foam products: foaming
prevents the detergent from
running down the wall, thus
prolonging its action time.
Agent for
simultaneous
cleaning and
preservation
These products contain care
components (e.g. hair waxes, plastics,
silicones) and cleansing substances.
The following types are mainly
distinguished:
- Solvent preservatives (contain care
components and organic solvents)
- Abrasion-free emulsions (contain care
components, surfactants, water and
organic solvents)
- Abrasive emulsions (contain care
components, surfactants, water,
organic solvents and soft polishing
agents).
Only recommended if minor
soiling must be removed.
Generally used for
components above the water
level such as diving boards and
handrails. Conservation
protects the stainless steel
surface from flash rust and
other damaging foreign
substances. Coloured stainless
steel may have streaks that
impair its appearance.
Preservatives - Solvent preservatives (contain organic
solvents and care components)
- Emulsion preservatives (contain care
components, water and surfactants as
emulsifiers).
Effect like "agent for
simultaneous cleaning and
preservation".

Before filling the pool, please check all installation parts and in particular all safety precautions for their
function and perfect fastening - loose screws/nuts must be tightened!
 Headlamps - Counter-current system
 Pool cover
 Gutter grates
 Ladders - Stair rails
 Fall protection
 Separation rope holders - Signs - etc.
 Water slide
 Bottom trunking lid: Ensure that the sealing lip is in the correct position, as it can fold over at one
end of the lid when inserted
 Check floor channel nozzles for seating, wear and completeness
 Check flood valves for centric seating and clean sealing surface
 Closing the slide valves of the tank drain
Then the filling of the pool can be started:
 either through floor channels integrated into the pool:
 when filling via floor channels, it is essential to ensure that a permissible filling pressure of 3 m WS is
not exceeded. The covers of floor ducts are designed for a maximum pressure of 5 m WS - in filled
condition. If the maximum permissible filling pressure is now exceeded - without water loading of
the filling water already in the tank - this can cause deformation of the floor duct covers and lifting
of the seals. This in turn would result in uncontrolled inflow effects. An even distribution of pure water
is no longer ensured. The filling pressure can be regulated accordingly by the pump pressure or
mains pressure.
 with the aid of an external service, such as the fire brigade by means of a "fire hose".
 or through filling spouts.
In large pools, where it is not guaranteed that the pool bottom will be filled with filling water, and where
the filling is also done during sunshine, experienced swimming champions use sprinklers in the shallow
areas to cool the bottom plate. This can prevent an uneven reduction of the thermal expansion of the
base plates (formation of wrinkles).
If the filling water has an extreme temporary hardness of more than 20° d.h., we recommend the use of a
softening plant, but a residual hardness of 8-9° d.h. should be maintained.
This serves to slightly buffer the pH value during the commissioning phase of the water treatment plant.
If the water treatment system (including chlorine dosing and pH neutralisation) is not put into
operation after new pool filling (for example in autumn before wintering),
- you must expect the onset of algae growth within a few days (depending on water
temperature and sunlight),
- we recommend to treat the water in such a way that no lime precipitation occurs in the
pool. I.e. adjustment of the acid capacity to approx. 2°dH.

3.4. Pool cleaning during operation
During the operation of the bath, the usual maintenance and cleaning work such as vacuuming the floor
etc. should/must be carried out. If necessary, the pool edges, side walls and channel grates can be
cleaned with soft stick brushes - while the filter system is running - immediately before backwashing.
Stainless steel components mounted above the water level or outside the pool must be cleaned at least
twice a week by flushing with drinking water to remove deposits with an increased chloride
concentration - due to evaporation of the spray water (e.g. starting base, railings, ...). They thus prevent
climate-related corrosion phenomena.
The clean and pool water quality must comply with the legal regulations and standards. The necessary
and prescribed fresh water addition must also be ensured.
Foreign objects such as coins, hair clips and the like should be removed from the pool at an early stage
to prevent foreign corrosion.
Bolts and nuts that loosen during operation must be tightened.
3.5. Hibernation
Basically, stainless steel basins may only be wintered when they are full!
Paddling pools and walking through pools, i.e. pools with very shallow water depth, should be emptied
and cleaned for wintering.
Before taking the bathing water treatment system out of operation, the chloride content and the pH
value of the pool water must be checked again and, if necessary, reduced to the value specified in
point 2.3. by adding fresh water.
For wintering we recommend adjusting the carbonate hardness so that no lime precipitation occurs in
the pool during the winter break. This means that setting the acid capacity to approx. 2°dH corresponds
to approx. 3.56°fH in Switzerland.
To prevent heavy lime and algae deposits on the stainless steel pool in winter, a winterising agent can be
added to the pool water before wintering. This makes spring cleaning easier - especially with hard water.
The addition of the overwintering agent must not cause the chloride content to be exceeded in
accordance with the specifications in point 2.3. The addition of chemicals must be carried out according
to point 2.4.6.
The supply lines of attractions such as gargoyles, splash rhinoceros, water mushrooms etc. must be
emptied at the end of the bathing season. Plastic attractions such as splashing rhino, children's slides etc.
should be placed in lockable rooms after the end of the bathing season.
The shut-off device of the outlet pipe of the expansion tank must be left open to ensure that rainwater
and meltwater can flow out of the gully.
Pipelines that may have been laid in the frost area must be closed at the basin side (except raw water
pipes) and emptied. As a rule, this concerns at least the tapping points for sample water. Here the
perforated plate cover must be unscrewed, the opening on the basin side (socket with pipe thread 1 ½")
must be sealed with the plug and the pipe must be drained. For this purpose, the water level in the basin
can be temporarily lowered (25cm to 35cm) - the resulting free space up to the overflow edge serves as
a buffer and will gradually be filled again by rainwater! Attractions installed in areas with shallow water
(e.g. seating step with air supply, etc.) may require additional or deviating measures to prevent frost
damage! This can be found in the respective design documents or, in case of doubt, we are available
for further questions.
Loose pool components such as channel gratings, separating lines, and possibly ladder rails should be
removed and stored. In the case of channel gratings, it is advisable to mark them due to the required
fitting accuracy and to stack them in the order of removal.
The pool cover must be wintered in accordance with the producer's instructions.

Ice skating in stainless steel pools is not advisable, since on the one hand mechanical damage in the
pool head area can be the result and on the other hand a continuous stability of the ice surface is not
ensured due to the thermal conductivity of the pool walls.
Ice pressure pads and other devices against ice pressure are not necessary. If, for any reason, water
losses occur during the winter phase that lead to the breaking-in of the closed ice cover, handrails
leading into the water can be damaged. Ensure that the supply and discharge pipes are closed tightly.
We are at your disposal for a consultation.
It is generally known that unattended swimming pools are a great danger for children. Please make
absolutely sure that outside of operating hours your entire leisure facility is always secured, closed and
inaccessible to unauthorized persons and children.
3.6. Equipment parts
3.6.1. Billboards
The stop boards of the swimming pool are designed to hold timing mats to be suspended during
competitions. There is a design risk of accidents with these parts. For this reason, they are to be used
exclusively during competitions or during swimming training for competitions and are to be removed
during normal swimming operations.
3.6.2. underwater spotlights / underwater loudspeakers / underwater cameras
WARNING electrical voltage. Risk of injury. Disconnect from voltage! Electrical installations may only
be carried out by a trained electrician!
Prior to maintenance or cleaning work, the complete lighting system must be disconnected from
the power supply and the relevant safety instructions of the manufacturer must be observed.
The lamps and luminaires must have cooled down before replacement.
 Headlight operation:
Switching on the headlights and a function test is only permitted when the pool is full. The
headlamps must be fitted for this purpose.
 Spotlight installation from the pool side (water side):
Place the spotlight on the pool edge, put the pressure screw and the sealing insert, which is
matched to the cable diameter, over the cable and then pull the rubber cable outwards through
the screw connection and the cable pipe; insert the sealing insert into the cable gland and seal it
with the pressure screw (you will find a slotted special bowl in our service box to tighten the screw
connections). When inserting the headlight, roll the rubber cable into the installation pot, insert the
headlight into the pot and fasten it with the screws supplied. The rolled up cable length in the
installation pot must be dimensioned in such a way that, during subsequent service work on the
spotlight, it can be unscrewed under water and placed on the edge of the pool.
 Service work on the headlamp (bulb replacement):
a) Halogen or PAR 56 lamps:
Unscrew the spotlight under water, place it on the edge of the pool and dry it. Install
replacement bulbs according to the manufacturer's instructions, paying particular attention to
the correct seating of the seals! Moisture in the lamp housing considerably reduces the service
life of the lamp and can lead to serious operating faults!
b) LED headlights:

Here, the electronics required for the lighting are usually tightly encapsulated with the housing.
An exchange by the user is usually not intended. In case of failure or reduced light output, the
headlamp shall be completely replaced or sent to the manufacturer for replacement of the
defective electronic components. You can find further information about the headlights
installed in your pool in our technical documentation or on the homepage of the respective
manufacturer.
 The sealing cable bushings must be checked regularly for leaks and replaced if necessary (in the
course of cleaning the pool) - depending on the system installed, either the complete PG gland or
only the sealing insert. In addition, the connecting cable of the headlight (especially the part of it
that is in the installation pot and thus in the water) must be checked regularly for damage and
embrittlement - via the smallest cracks in the protective sheath of the cable, moisture can reach
either the headlight or, in the other direction, the power supply unit and cause damage in each
case! As a guide as a result of normal wear and tear, a scheduled cable replacement should be
provided after approx. 5 years of operation!
 Information on sealing and maintenance applies analogously to other systems installed in
installation pots in the pool, such as Underwater loudspeakers or systems for pool monitoring -
detailed information can be found in our technical documentation, where applicable.
 For large pools where the pool wall is accessible from the rear (technical basement), systems can
be installed with operation from the outside (=underwater window with spotlight installed behind it
or also a surveillance camera). Replacement lamps must be installed in accordance with the
manufacturer's instructions - the tightness of the glass pane to the pool must be checked regularly!
4. PASS-THROUGH POOL
When cleaning pass-through tanks, proceed as described above.
We would like to point out that stainless steel pass-through pools must be filled and operated while the
bath is being opened. Emptied stainless steel walk-through basins can cause burns and injuries when
exposed to sunlight.
