More information
HYPERTHERMIA
Prolonged immersion in hot water may cause
hyperthermia, a dangerous condition that
occurs when the internal temperature of the
body exceeds the normal value (37°C).
The rst symptoms of hyperthermia include dizziness,
fainting, drowsiness, lethargy and a body temperature
higher than 37°C.
The physical effects of hyperthermia include
unawareness of impending hazard, failure to perceive
heat, physical inability to exit the minipool, foetal
damage in pregnant women and unconsciousness
resulting in a danger of drowning.
The use of alcohol, drugs or medication can
greatly increase the risk of fatal hyperthermia
in hot minipools.
If you suspect hyperthermia pull the person out of the
minipool and immediately call for medical assistance.
While awaiting assistance, take the person to a cool
place and let him or her to lie on his or her back with
the head slightly raised by a pillow.
SAFETY INSTRUCTIONS FOR
MAINTENANCE
Perform maintenance on your minipool
on a regular basis as this will maintain
the surfaces and functional parts in optimal
condition and also ensure maximum hygiene
and safety when using the bathtub.
During the maintenance of the bathtub
and the use of chemicals, always use
personal protection (e.g., protective gloves
and glasses).
For routine maintenance, use only the
products indicated by the Manufacturer:
other types of detergents or disinfectants
could irreparably damaging the minipool
surfaces and circuits (damage resulting from
the use of unsuitable products is not covered
by the warranty).
Unauthorised actions, tampering or
modications that do not follow the
information provided in this manual can cause
damages, injuries or fatal accidents and null
and void the warranty.
Persons not involved with equipment
maintenance may not pass through or
occupy the work area.
Before performing any maintenance
disconnect the electricity and water
Safety instructions
supply.
Being potentially toxic by ingestion and
contact, cleaning and disinfectant
products must be kept tightly closed and
out of the reach of children or pets. When
not in use, store these chemicals in their
original labelled and well sealed containers
in a cool, dark place, away from heat
sources.

Use
1BEFORE USING THE
MINIPOOL...
Read these chapters before using your new minipool.
They will provide you with useful tips to use it safely with
maximum benet.
USE ADVICE
• When using the minipool, do NOT wear loose clothing,
pendant jewellery and tie up long hair to avoid the risk
of becoming caught in moving parts.
• The time in the minipool should never exceed 20
minutes.
• Use the whirlpool at most three times per week.
• Inside the minipool DO NOT use foaming detergents,
soaps, bath oils, greasy lotions or products that are not
compatible with the minipool.
• Before entering the minipool take a shower to remove
any fatty substances (e.g., sweat, suntan lotion, etc.)
that could make the water cloudy and oily.
• The paving around the minipool may become very
slippery. Be careful when entering or exiting the water.
TIME IN THE WATER
For a relaxing experience the ideal water temperature
is about 33-37°C for a duration of about 20 minutes. In
fact, a temperature equal to that of the body fosters
vasodilation and muscle relaxation.
For an energising experience, soak for about 10 minutes,
preferably in the morning, at about 33°C.
For a draining experience, use the whirlpool for 5-8
minutes at a maximum of 35°-37°C. After leaving the
minipool relax for a few minutes to allow the pressure
altered by the heat and massage to return to normal.

CHROMATHERAPY
Light is made up of seven basic colours: red, orange,
yellow, green, blue, indigo and violet. The classic
example of the colour spectrum that we nd in nature
is the rainbow.
The Egyptians, Greeks and Romans practised
heliotherapy (exposure to direct sunlight) for the
treatment of various disorders.
In India, ayurvedic medicine has always taken into
account how colours affect the balance of the Chakras
and how they can help the body and psyche to restore
their natural balance.
Red: dissipates the deepest fears and maintains the
person well anchored to the present and to the solidity
of the earth.
Orange: stimulates feminine creativity, optimism and
serenity.
Yellow: brings out emotions and desires, personal power
and the ability to perceive the qualities and feelings of
others.
Green: reawakens love and openness towards others,
selessness, inner goodness.
Blue: promotes the ability to listen to others. It is related to
the expression of one's personality, creativity, imagination,
relaxation.
Indigo: has the ability to broaden our understanding
and treat disorders that affect sensory organs like eyes,
nose and ears.
Violet: cool colour that promotes spirituality, inspiration
and imagination.

es, ensuring that the products used are formulated to
be compatible with the minipools in laminated resin.

FILLING THE MINIPOOL
Filling is carried out by following the gures on the side
(follow the instructions for your keypad).
This occurs through a concealed spout in the compartment
on the bottom of the minipool and is indicated by the
illuminated red LED.
Filling takes place from the bottom of the bathtub, and
once it has nished the tank is lled.
After reaching the correct level, the system automatically
stops the lling and makes available the functions of
whirlpool, recirculation, ozone and heater.
During minipool use the system automatically maintains
the water level equal to the edge of the bathtub.
The minipool must ALWAYS remain connected to both the electrical grid and plumbing (lling and draining): this is
necessary for ltering, cleaning the lters and maintaining the minipool's water levels and temperature.
ALWAYS cover the minipool when inactive. This protects it from the sun's rays, prevents dirt from accumulating
inside the bathtub and keeps it from losing heat, thus optimising the efciency of the heater.
DRAIN AND SUCTION PUMPS
The minipool drain is positioned on the bottom, hidden
by the nishing plate.
This solution makes the use of the bathtub safer and
more comfortable.
To clean the drainage grate, just manually remove the
nishing plate since it is simply resting on the bottom.
For this operation see page 14.

WHIRLPOOL
This minipool is equipped with the patented GHOST
SYSTEM© whirlpool, a system that is truly invisible, which
allows for extremely simple design solutions for bathtubs
that are completely free of external nozzles and jets.
GHOST SYSTEM©, an exclusive patent of Treesse Group,
owes its name to the invisibility of the components, fully
incorporated in the bathtub. The system is distinguished
by two thin internal perimeter slots that host a large
number of jets that are properly oriented.
For this operation see page 14.
MIXING FUNCTION
Treesse minipools feature an automatic mixing
function during which the whirlpool pump is
activated.
This process is used to mix the water in the
bathtub to have a more effective ltering action.

More information
WHIRLPOOL
The whirlpool has a very positive effect on disorders like insomnia and anxiety. It also facilitates muscle relaxation
and is therefore great after sports. It increases blood ow and helps to lower blood pressure. It also exerts a
lymphodraining action contributing to the elimination of imperfections like cellulite, also thanks to its massaging
action. It provides numerous benets by stimulating blood and lymphatic circulation. The water temperature
is very important: water at 37-38°C is relaxing and promotes circulation, while the cooler temperatures have a
toning and stimulating effect and can increase blood pressure.
The whirlpool also promotes mental harmony, relaxation and physical well-being.

13
Fusion Spa minipool

U
CHROMATHERAPY
Chromatherapy is standard on the innity version, while
on the version with two perimeter slots it is optional.
The light "magically" moves the whirlpool in the bathtub.
For this operation see page 14.
OVERFLOW EDGE
The overow edge of the minipool collects excess water
and conveys it to the collection tanks under the bathtub.
The water level is always constant, allowing for relaxation
and a total wellness experience.
The water that overflows is recovered, filtered and
automatically recirculated within the minipool through
the intake grille.
The minipool works exclusively when the bathtub
and tanks are full of water.
The edge is designed to recover the overowing
water, not for abnormal movements caused by an
improper use of the minipool (e.g., diving).
In this regard we strongly recommend entering the
bathtub and getting in the water slowly.
When the recirculation of the water overow is active,
the heater automatically activates to manage the water
temperature.

OPERATING MODES
ACTIVE MODE
In ACTIVE mode, the minipool is maintained in a condition that is readily usable by the user.
In this state, if there are no alarms all the functions are operational and the recirculation pump is always active to
lter the water.
When switched on, the control panel is set to the same state that it was in before it was turned off.
SLEEP MODE
SLEEP mode is used when the minipool is expected to remain unused for some time.
The water is therefore kept at a temperature (which can be set by the user) that is lower than that of normal use
(the default value is 25°C, the minimum temperature that can be set is 13°C).
STANDBY mode is maintained even in the even of blackouts and power surges.
In this state, the functions are deactivated and the recirculation pump - if no water level alarms are active - is
activated to maintain the temperature or to lter the water.
When the minipool is in STANDBY mode:
• The display shows the message "SBY".
• The heater starts working to maintain the temperature set (default value is 25°C).
• Filtering is in operation.
• For ltering with sanitising both the pump and the ozonator are activated twice a day (every 12 hours).
By default, the maintenance temperature during standby is 25°C. To change it (down to a minimum of 13°C):

SPECIAL FUNCTIONS
BACKWASHING
3 seconds
10 seconds
Water ltration takes place through a sand lter connected to
the recirculation pump.
Cleaning the sand lter is essential because it retains polluting
materials like hair or leaves and sediment if the minipool is
installed outdoors.
The best cleaning is achieved with a backwash, i.e., with a
jet of clean water from the bottom of the lter so that the dirt
can ow into the drain.
The cycle lasts 20 minutes.
In Treesse minipools backwashing is automatic, running
automatically every 48 hours of minipool use, but can be
forced manually by pressing:
the key for about 10 seconds
backwashing in progress is indicated by the
LED
t he key for about three seconds
backwashing in progress is indicated by the
appearance of the word "FLT" on the display
Backwashing disables:
• The recirculation pump
• The heater
• The ozonator
A backwash cycle can be interrupted only by turning off the
power switch of the minipool.
It is recommended to change the sand every year
(see page 30).

sensor alarm
(alarm)
Problem description: a temperature sensor measures the water temperature
inside the minipool, activating the heater when necessary.
The allowed water temperatures range from 5°C to 45°C. Values outside
the range cause the blocking of all functions and the permanent activation
of the alarm message.
Solutions: the alarm will reset automatically once the temperature
returns to allowed values (5° to 45°). The message is also displayed if
the temperature sensor malfunctions.
Solutions : make sure that the water temperature is not outside of the
permitted values, try to disconnect the power supply to the bathtub
and switch it on again after 30 seconds. If the problem persists, verify
that the connection with the control unit is correct and has not been
tampered with. Otherwise contact the Manufacturer.

Problem description: the alarm occurs when, after a lter backwash, lack
of ow continues for more than 5 minutes. The system stops, all functions
are disabled and the display shows the xed "FL" alarm.
Solutions: The alarm resets only by switching off the minipool and turning
it back on after about 30 seconds.
The main causes of what has been described are attributable to:
1Excessive dirtiness of the sand in the lter due to an incorrect
treatment of water in the minipool (see the section on water
treatment on page 24). In this second case, empty the minipool,
disassemble the lter and check the sand. Depending on the
problem found when the lter was opened use suitable products
to wash the sand. Finally, replace the sand (see page 30).
2Damage to the ow sensor (contact the Manufacturer).
3Damage to the circulation pump. Once the minipool restarts, verify
that the circulation pump functions correctly. Try to perform a manual
backwash of the lter (see page 30).

for about 30 seconds, check that the level sensor cable is not damaged
(e.g., crushed by something), restore power to the minipool.
If the problem persists, contact the Manufacturer.
