Please note
The Manufacturer cannot be held responsible and does not recognise the warranty in the case of:
• Installations or connections that are not compliant or that are carried out without following the national
regulations concerning civil and industrial installations.
• Pre-installation and installation carried out by unqualied personnel or otherwise not in compliance with the
instructions in the pre-installation and installation manuals.
• Incorrect preparation of the installation environments, including the supporting surface.
• Accidents and damage due to a non-compliant installation or use of the bathtub.
• Masonry works that prevent the removal and handling of the minipool or defective parts thereof.
The bathtub works efciently and safely if it is installed correctly and in compliance with the regulations in force in
the country of use.
This pre-installation guide provides information for a proper preparation of the environments and the plumbing and
electrical connections.
This allows for a quick and safe installation.
The pre-installation stages involve the following professionals:
• A construction engineer for the calculation of the loading capacity of the platforms or oors.
• A qualied and certied company that will prepare the installation site according to the instructions provided in
this guide, following current work safety regulations.
• Certied and qualied electrician and plumber who prepare electrical and plumbing systems in compliance with
local and national regulations regarding civil and industrial systems.
The user must promptly notify the professionals of any existing underground obstacles like gas or water lines and
electrical or telephone cables.
Upon completion of pre-installation all these specialists must issue a declaration of conformity of the systems installed.
Without such document, the Manufacturer cannot be held responsible for damage to the systems or premises where
the bathtub will be installed.
An incorrect pre-installation could cause structural damage to the bathtub and void the warranty.

2WHAT PREPARATIONS ARE REQUIRED?
To be installed, the bathtub requires:
1Identication of the installation site.
2Preparation of the installation site.
3Preparation of the plumbing.
4Preparation of the electrical system.
The following pages will provide detailed
explanations of how to perform these
preparations.
EXAMPLES OF BATHTUB INSTALLA-
TION

14
Pre-Installation Fusion SKI bathtub
EN
3IDENTIFICATION OF THE INSTALLATION SITE
When choosing the position, take into account
the local regulations that prohibit any electrical
installation (plug sockets, switches, lamps, etc.)
in the area surrounding the bathtub for a distance of at
least 60 cm and a height of 230 cm.
When choosing the position, bear in mind that
the inspection side (electrical/plumbing
components side) must always remain accessible
for future maintenance.
OUTDOOR INSTALLATION
It is prohibited to install this type of bathtub outdoors.
INDOOR INSTALLATION
Note that the evaporation of water in the bathtub in the
presence of high internal temperatures can generate very
high levels of humidity in the environment.
To overcome this drawback, choose an environment with
good natural or forced ventilation. As an alternative,
install a dehumidication system. Humidity damage is
not covered by the manufacturer warranty.
Take into account the size of the bathtub: narrow
passages, doors and steps can be an obstacle to
its transport to the desired place.
Before preparing the supporting surface, see the
sections on the plumbing and electrical
connections for positioning the connections
correctly.
During installation remember that the bathtub must be easily inspected or moved for any ordinary and extraordi-
nary maintenance operations.

15
Pre-Installation Fusion SKI bathtub
EN
4PREPARATION OF THE INSTALLATION SITE
FREESTANDING INSTALLATIONS
As a base, create a platform or ooring in reinforced concrete, able to support the weight of the bathtub and the
people using it.
The manufacturer suggests a minimum load of 350 kg/m2.
In any case contact a qualied construction engineer to calculate the appropriate load for the installation site.
Wedges or shims cannot be placed under the bathtub to level it, only the feet of the bathtub can be ad-
justed.
Remember to ground the structural reinforcement in accordance with electrical codes.
For the preparation of the water and electrical connections see the pertinent section on page 18 and 20.
Flooring (it is recommended to choose a
flooring that minimises the possibility of
slipping when getting in and out of the
bathtub)
Concrete slab with a thickness suitable for
supporting the weight of the bathtub + the
weight of the people within
See the plumbing and
electrical preparations on

Pre-Installation
OPTIONAL
RECESSED INSTALLATIONS
As a base, create a reinforced concrete recess having a
thickness that is able to support the weight of the bathtub
and the people using it.
The manufacturer suggests a minimum load of 350 kg/m2.
In any case contact a qualied construction engineer to
calculate the appropriate load for the installation site.
Wedges or shims cannot be placed under the
bathtub to level it, only the feet of the bathtub
can be adjusted.
Remember to ground the structural reinforcement in ac-
cordance with electrical codes.
If it was not possible to provide a technical inspection
port on all sides of the bathtub, a pneumatic lift is
available (OPTIONAL - to be requested from the
Manufacturer) in
order to simplify
future
maintenance
operations. It is
recommended to
provide a
removable
inspection hatch
"A" positioned on the side where the bathtub components
are situated.
Prepare:
• AA technical inspection port at least 50 cm wide on all
sides of the bathtub. This will make future maintenance
or repairs easier.
• BDrainage grating around the perimeter and in
the recess to help preserve the equipment and the
structure (even for indoor installations).
• CFlooring (it is recommended to choose a ooring
that minimises the possibility of slipping when getting
in and out of the bathtub).
• DTwo Ø15 cm vents to ensure proper ventilation and
extraction of the heat and moisture from the technical
compartment.
• EInsulation.
For the preparation of the water and electrical
connections see the pertinent section on page 18
and 20.

The water connection must be dedicated exclusively to the bathtub (it is not possible to connect other equipment
to the same connection) and carried out with new and never used hoses and couplings.
It is recommended to use ONLY tap water as it guarantees microbiological purity and absence of metallic
particles or organic substances.
In contrast, well water generally contains these substances which can cause algae blooms and serious damage
to the bathtub. If water service is not available, install lters (ltration of no less than 50 microns) upstream of the
plumbing system that guarantee characteristics comparable to those of tap water.
The company is not liable for problems resulting from failure to install them.
5PLUMBING PREPARATIONS
More information
TAP WATER AND WELL WATER
To ensure maximum hygiene and durability of the bathtub it is essential to pay close attention to the quality of
the water that will be used to ll it. It is important that the water used be drinkable. It is always advisable not to
use well water because it may be very hard, rich in metals like iron and manganese, and have bacterial loads. Tap
water is recommended.
In the case of very hard or ferrous water it is always recommended to install softening and iron removal systems
upstream.
The company cannot be held responsible for issues related to the use of non-drinkable water or lack of installation
of such systems.
The plumber is responsible for choosing the type of components to be used and the verication of compliance
with the purity and potability parameters of the water supply.
WATER HARDNESS
Water hardness (TH) is determined by the total content of calcium and magnesium present in the water, coming
from their soluble salts.
Water classication:
...... ..up to 7ºf = Very soft water
From 7ºf to 14ºf = Soft water
From 14ºf to 22ºf = Slightly hard water
From 22ºf to 32ºf = Fairly hard water
From 32ºf to 54ºf = Hard water
........more than 54ºf = Very hard water
(1°f = 10 mg calcium carbonate per litre of water)
Position of the plumbing connections: see initial pages.

EXAMPLE OF PRE-INSTALLATION PLUMBING FOR A BATHTUB

20
Pre-Installation Fusion SKI bathtub
EN
The Treesse minipools are built in compliance with
European laws (EN 60 335-2-60) and are tested during
production to ensure the safety of the installer and user.
The electrical preparations are to be performed by a
suitably qualied and certied electrician.
All electrical preparations must be performed only
after disconnecting the electricity in the work area.
The electrical connection must be:
• Performed in a xed and permanent manner, without
intermediate splices, in accordance with regulations of
the country of installation.
• Sufcient for the current absorbed by the bathtub
(see technical specications).
• Provided with a functioning ground as per current
regulations.
• Protected against splashing water, then placed
in a dedicated room, closed and sheltered from the
weather.
6ELECTRICAL PREPARATIONS
• Controlled by a multi-pole switch with a contact gap of
at least 3 mm and a breaking capacity equal to 60A (or
in any case adequate for the absorption of the bathtub).
• Controlled by a differential switch no larger than
30mA.
The control unit's power supply cable must be of the H05
type with three wires (single-phase 220V) whose gauges
are adequate for the absorption of the bathtub (see
pre-installation sheet). Its size depends on the absorbed
current and the distance of the bathtub from the main
electrical cabinet.
The Manufacturer is not responsible for connections
made in a way that does not comply with local
codes, the specications in this pre-installation
sheet or tampering with any electrical component of the
bathtub.
