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.
