1. FOREWORD
Once you have built your pool, keep the documentation (installation instructions, invoice, etc). You will
need these for any future exchanges with our various services.
Great care has gone into the manufacture of your pool, however, some precautions are necessary for its
correct assembly and use. We strongly recommend that you read the installation instructions carefully
before beginning assembly of the pool, and that you keep them for future reference concerning the use
and maintenance of the pool.
In the event of any claim, you will need to quote the pool’s tracking number that you will nd at the end of
this document.
1.1 Presentation
POOL’N BOX JUNIOR pools are innovative: they associate the attributes usually associated with large, top
of the range pools with the practical advantages of more modestly sized pools. With its smaller footprint,
this pool can be installed wherever you would like.
With a water surface area of less than 10 m2, everything nds its place with POOL’N BOX JUNIOR.
1.2 Storage
If you do not intend to assemble your pool immediately, do not unpack the components, store the boxes
in a suitable, well ventilated, cool area protected from the sun and bad weather. The purpose is to avoid
deformation of the wooden elements that would make assembly more difcult.
Deformation of the wood could only be caused by storing the wood other than as recommended. If you had
to unpack your pool, you must repack and restrap the pallet of wooden elements.
Once the wooden elements are unpacked, proceed with assembly within the next 24 to 48 hours. While
storing the boxes, we recommend that you remove the lm and insert wooden wedges between each layer
of wood to facilitate the circulation of air.
1.3 Safety
Your electrical installation must comply with the standard in effect in the country of installation (C15-100 in
France). Notably, the electrical supply of the pump should be protected by a 30mA residual current device.
Do not hesitate to have this work carried out by a professional to ensure the compliance of your installation.
Children should only use the pool under the supervision of an adult. This pool is intended for private use only.
Installation of the pool beneath trees is not advised, installation beneath electrical wires is strictly prohibited.
Remember to remove the wooden access ladder after each use to prevent unsupervised access to the
pool.
We recommend that access to the pool be secured by one of the means of protection set out in the
standards NF P 90-306,307,308,309 that is: safety barrier, alarm, safety cover, shelter.

WOODEN POOLS BWT myPOOL POOL’N BOX
1.4.2 Tools
Excluding the materials required for excavation and pouring the concrete slab, we recommend that you
have the following equipment on hand:
• measuring tools: decameter, rope, big spirit level
• mallet
• percussion drill with concrete drill bit, diameter 10 mm
• drills and drill bits, at head screw diver, cross head screw driver, drill bit diameter 10 mm
• cutting tools: Stanley knife, metal saw, hole saw diameter 60 mm
• tube or socket wrench (13 and 17mm), set of Allen keys
• nishing tools: sand paper, lime ne
1.4.3 Assembly time
Excavation and earthworks: 1 TO 2 DAYS DEPENDING ON THE MATERIALS USED
Metallic structure: ½ DAY (WITH 2 PEOPLE)
Pouring the slab: ½ DAY (WITH TWO PEOPLE) DEPENDING ON THE MATERIALS USED
Wooden structure: 1 DAY (WITH TWO PEOPLE - THE TIME INDICATED DOES NOT INCLUDE
THE CONCRETE CURING TIME)
Curing of the concrete slab: 21 DAYS (3 WEEKS)
CAUTION
Once the structure has been assembled, the liner must be tted and the pool must be lled with water
within at most 5 days. Past this time limit, the structure will need to be carefully inspected to ensure
the absence of any deformations (movement of the slats, shrinkage, etc.) that could impact the
structural integrity of the work. In the event that gaps appear between the slats, ret them perfectly
before tting the liner.

3. WOOD, A NATURAL MATERIAL
Being a natural material, wood will have some imperfections. These are normal and have no impact on the
service life of the product.
A certain number are supercial and do not fall within the scope of the guarantees.
3.1 Colour variations
Colour variations are common to every species of wood.
Treatment brings them out because the depth of penetration of
the product depends on the wood density and grain. Weathering
of wood outdoors will signicantly attenuate these colour
variations.
3.2 Resin beads
When resinous wood species are autoclaved, the alternating
pressure and vacuum can cause sticky residue to rise to the
surface. To remove it, scrape it carefully with an appropriate
tool, being careful not to touch the wood. Turpentine spirits
could also be effective, but could stain the wood if too much is
applied.
3.3 Salt stains
Small green stains are frequently found on the surface of
autoclaved wood. These can be removed with light sanding. If
left untreated, this colour will disappear over time.
3.4 Greying
Wood exposed to the sun and the moon is susceptible to
greying. Some of the wood could already be greyed due to the
storage conditions of the various elements of the structure.
This is a natural phenomenon that has no impact on the structural
integrity of the product. The colour of the whole structure will
even out after a few months of exposure..

HOTLINE
WOODEN POOLS BWT myPOOL POOL’N BOX
3.5 Splitting and cracking
Wood expands and contracts when exposed to variations in
humidity and temperature. As it dries, wood contracts unevenly
resulting in the appearance of cracks. While these can seem to
be cause for concern, they have no impact on the mechanical
properties of the product and therefore do not fall within the
scope of the guarantee.
3.6 Knots
Knots mark the places where branches were attached. The
quantity and size depends on the species of wood and the
sorting process. For outdoor installations, small adherent knots
are acceptable.
3.7 Surface mould
.
Mould, caused by microscopic fungi, can grow on wood,
particularly on resinous species, on which the growth can
appear as “blueing”. It is a surface phenomenon, exacerbated
by heat, humidity and inadequate aeration and is characterised
by stains ranging from light to dark blue. They can be removed
by wiping the surface.
Remember that class IV treated wood is protected against
attack by fungi that could destroy the physical and mechanical
properties of the wood
3.8 Joined wood
To ensure the highest quality in the selection of our wood, it
is sorted meticulously before planing. Sections that features
defects on both sides are removed and the wood is then joined
together (see image).
This is no way penalises the mechanical properties of the wood.
3.9 Curved wood
Due to the constant pressure exerted by the water, the walls of the pool may curve slightly over time.
This phenomenon, attributable to the natural elasticity of wood, will stabilise of its own accord and in no
way would lead to failure of the wooden slats.
It is not a defect, and would not constitute grounds for a guarantee claim.
