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.

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:

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.
