SAFETY
Carefully read and follow the information contained in this manual before installing and using
the spa. These safety warnings, instructions and guidelines refer to the most common risks
associated with water activities, but do not cover all risks and damage that may occur.
Always pay attention and use common sense during activities in and around the spa.
• If children are present, assign a competent adult to supervise the spa during its use .
• When the spa is not in use or unsupervised, remove all toys in and around the spa to avoid
attracting children to the tub.
• When the SPA is not used, always cover it with its thermal cover to reduce consumption and for
safety .
• Keep a telephone and a list of emergency numbers near the spa.
• Encourage children to learn to swim.
• Know basic resuscitation techniques and keep them up to date. This can make all the difference
in an emergency situation .
• Instruct all spa users, including children, on what to do in an emergency.
• Do not dive into the spa or enter by jumping: these behaviors can cause serious and permanent
damage .
•Do not use the spa under the influence of alcohol or drugs that could compromise the
ability to use the tub safely .
If there are covers, remove them completely from the surface of the water before entering
in the tub .
•To preserve the healthiness of the water, follow the correct water treatment and the
practices of hygiene
•Store the chemicals for hygiene treatment in the tub out of the reach of children.
• Report the presence of the spa within 2 m of it.
• The water in the spa must never exceed 40 ° C. Lower temperatures are recommended in the
presence of children and for uses that exceed 10 minutes.
•Excessive water temperatures have a high probability of causing fatal damage during the
first months of pregnancy. Pregnant women are recommended to limit the use of the spa,
always avoiding high temperatures.
The use of the cover or other safety devices such as barriers and alarms is recommended to

TEMPORARY STORAGE
The installation of the tub should be done immediately after receipt. However, once unpacked, if
it is necessary to temporarily place it on a surface awaiting installation, it will be necessary to
prepare a solid and flat base with, for example, under the entire bottom of the tub, concrete slabs
with a minimum thickness of 5 cm. . It is recommended to leave the tub in that position for as
little time as possible.
Do not leave the tub empty in direct sunlight: the surface temperature could reach high levels of
temperatures, which could cause malfunctions and damage, including deformation of the surface
and components. Damage resulting from direct and prolonged exposure to sunlight is not covered
by the warranty. In the case of an installation in such conditions, provide a cover (fixed or mobile)
to protect the SPA.

WARNING
INSTALLATION LOCATION: HOW TO CHOOSE
The installation of the SPA must be carried out in compliance with the safety standard CEI 64-8 / 7 and
subsequent amendments. When choosing the positioning, take into account that the inspection sides
(inspection doors) must always remain accessible for future maintenance. The recommended ambient
temperature for the hot tub must be between -5 ° C + 45 ° C, with a relative humidity of 20 - 80%.
External Installation
The presence of trees or hedges near the tub, with possible loss of debris (eg leaves), could
cause damage to the equipment over time (not covered by warranty) and lead to more expensive
and frequent maintenance. Also evaluate the best position to safeguard one's privacy and respect
for others and the best panoramic or climatic position compatibly with local regulations. An area
exposed to the morning sun guarantees greater well-being for users.
Pay attention to the characteristics of the ground on which the support platform will be built: sandy
and unstable soils or subject to flooding could compromise the stability of the base over time and
therefore the safety conditions of the hot tub itself.
Internal Installation
The evaporation of the water from the hot tub, in the presence of high internal temperatures, can
generate very high humidity levels in the environment: choose an environment with good
ventilation, natural or forced. Alternatively, set up an air treatment system. Damage caused by
humidity is not covered by the warranty.
Pay attention to the dimensions of the hot tub: passages, doors, steps, can be an obstacle to its
transport to the desired place.
If you install the whirlpool tub inside, it should be remembered that the tub must be easily
inspected or moved for any ordinary and extraordinary maintenance operations .
INSTALLATION LOCATION: HOW TO PREPARE
Before creating the support surface, consult the sections of the hydraulic and electrical
connections to correctly position the connections.
The correct positioning of the tub is determined by the support surface. It is not possible to insert
wedges or shims under the hot tub to level the top.
Above ground installation (with lateral panels)
Create a base or floor in reinforced concrete that is flat and suitable for supporting the weight of
the hot tub and its guests. Check the load capacity of the installation site for a weight of 300 kg /
m2 .

MAINTENANCE MANUAL
YUI pag. 8 di 16

Ver 01 –2021-07-09
We suggest:
1. The creation of perimeter drainage grates to facilitate the flow of water that can
accidentally come out of the tub and for easy cleaning of the installation site for indoor
installations;
2. The installation of an anti-slip flooring in the perimeter area of the hot tub.
No-slip floor Drenage grid (raccomended)
Example:
thickness ≥ 10 cm
< 25/30 with electro-welded net ⌀
6
Concrete basement
(raccomended)
Installazione ad incasso
It is necessary to create a self-supporting underground compartment that is stable over time and
able to contain the thrust of the ground, with a flat bottom and suitable for supporting the
weight of the hot tub and its guests (300 kg / m2). Check its load capacity.
The implementation of :
1. a technical inspection compartment at least 50 cm wide on the short sides of the mini pool, this
will make future maintenance or repairs easier ;
2. perimeter drainage grates and internal to the recessed niche to facilitate the flow of water
3. and to help preserve the equipment and the structure (also for indoor installations);
4. a non-slip flooring in the perimeter area of the pool;
5. two Ø15 cm grids to ensure proper ventilation and extraction of heat and humidity from the
technical compartment, this prevents the accumulation of condensation which over time
can cause bad smells and damage to all the main electrical and electronic components of
the SPA ;
6. IN OUTDOOR BUILT-IN INSTALLATIONS, to avoid any damage due to frost, we
recommend providing insulation for the tub compartment. The choice of materials and
thickness must be made on the basis of the minimum temperatures reached in the country
of installation. It is recommended to make a hydraulic connection to the drainage network
that allows easy drainage for wintering the SPA or for prolonged periods of non-use .
WARNING
It is mandatory to provide for the possibility of easy removal of the tub from the installation space.

HYDRAULIC PREPARATIONS
Make a water connection with a dedicated line to the hot tub (do not connect other
equipment to the same connection) and made with new and never used hoses and joints.
For loading it is recommended to use mains water (aqueduct) as it guarantees
microbiological purity and the absence of metal particles (not retained by the filtering
system) or organic substances. The use of well water is strongly discouraged, as it may
contain substances that can cause the proliferation of algae, stains and serious damage to
the hot tub. If the water service is not reached, install filters (filtration not less than 50
microns) and metal subtractors upstream of the loading line that guarantee characteristics
comparable to those of the water supplied by the aqueduct. Failure to install systems that
ensure an adequate level of the quality of the loading water determines the discharge of any
liability arising from the failure to install the latter .

CLEANING AND MAINTENANCE FILTER CARTRIDGES *
The filter cartridge must be cleaned regularly, using clean water, with a maximum
frequency of 7 days: this will be increased according to the workload of the tub and
the increase in water temperature.
Clean the surface with neutral soap to degrease the surfaces and rinse until
completely clean.
Do not use brushes or high pressure washing.
It is recommended to replace with a new filter every 3 months, in case of intense use
(SPA ad public use) and 6 months for domestic use. Always replace the complete set.
A clogged filter or series of filters can significantly reduce the life of the electrical
equipment involved in the filtration (pumps, heaters, etc.): the manufacturer declines
all responsibility for damage resulting from this condition.
• Remove the cartridge protection package (plastic film if present)
• Remove the floating lid of the skimmer by rotating it before removing it
• Remove the filter cartridge
• Wash the cartridge with water and neutral soap or dish detergent and, once rinsed thoroughly, put
it back in its seat
• Replace the lid on the top of the filter basket
TUB CLEANING
1. Clean the hot tub with a mild detergent and a soft cloth. Do not clean with
acetone, ammonia solution and organic solvent, otherwise the surface of the tub
may be damaged.
2. Remove limescale from the bathtub using a mildly acidic detergent such as citric
acid or vinegar, rinsing thoroughly.
3. Do not rub the chrome parts (avoid contact with solvents)
4. Cleaning the whirlpool system: pour hot water up to the surface of the nozzles,
add an adequate amount of detergent, start the whirlpool for 5 minutes, stop the
pump and drain the water, then add clean water and start the whirlpool for 3
minutes, stop the pump, drain the water and clean the bathtub with a soft cloth.

WARNING
• Do not clean the tub with rough tools, chemical solvents or grainy cleaners.
• Avoid letting the bathtub come into contact with lighted cigarettes or heat sources.
• It is necessary to drain the water from the tub if this is not used for more than 3
consecutive days (no power supply).
• When using the whirlpool, avoid adding foaming materials.
• Avoid using cosmetics.
• Check the performance of the differential switch regularly and at least
• once every 2 months.
• Periodically check that the main power line, switches and connectors are not damaged.
• Periodically check the water delivery and discharge pipes, check that the
unloading takes place without problems.
• Be careful when moving the product: avoid excessive pressure, mechanical kickback or intense
vibrations.
• Drain the water from the SPA when it is not in use for a long period of time, keep the installation
environment dry and ventilated.
COVER INSTRUCTION (option)
Always cover the tub with the thermal cover to minimize the heat loss of the water between one use and
another, but never during its use. Make sure that the cover is correctly positioned and that the soft flaps
are well laid out on the sides, so as to maximize insulation.
It is recommended not to lay the cover on the ground while it is not in use, in order
to preserve its cleanliness, especially for the part that is directly in contact with the
water of the tub. The cover should have its own storage place where it is not likely to
be damaged and where it cannot cause dangers
WARNING
Always remove the cover from the tub during use; failure to comply with this
standard can expose users to serious health risks .
