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.

• 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..

10/36 2021/03 - Version: B Code : 37371
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.

4. EARTHWORKS
4.1 Introduction
After determining the ideal position for your pool (preferably, orient the pool so that skimmers face into
dominant winds), start with the excavation required to accommodate the concrete slab that will seal in the
support braces and form the base of your pool. Seek the assistance of a professional if required.
Never backll under the pool to achieve a level surface, the layer of stone bedding and the slab must be
seated on stable ground.
For an above-ground installation, the plant housing and drainage system are not required. The excavation
and the slab will be rectangles, 4555 mm long and 3190 mm wide.
4.2 Creating the excavation
4.2.1 Material quantities
The quantities of materials required are shown in the table below
Estimated volume of stone bedding 1.6m3 20/40 gravel
Geotextile surface area (pool oor)
14.5 m² non-woven felt
Polyane surface area
14.5 m² polyethylene sheet
Theoretical length of the Ø80 mm drain
14.8 m PVC
Rebar
4.7 x 3.1 m ST25C rebar
Slab, 15 cm thick
2.3 m3 C25/30 concrete
The materials and quantities listed are for guidance. The concrete slab under the pool must be built in
accordance with the rules of the art.
4.2.2 Excavation
Dig out an area, the length and the width of which should correspond to the length and width of the inner
walls of the pool increased by 0.55 m around the entire periphery of the pool, that is, 4.46 x 3,10.
For an above-ground installation, so that the slab is ush with the ground, excavate to a depth of 0.26 m.
Take care, these measurements may be greater if the moisture content of the wood is high when the
pool is installed (wood stored in a humid or poorly ventilated area).
4.2.3 Stone bedding
Level the oor of the excavation as much as possible, and then roll out the geotextile to cover the entire oor.
Using 20/40 mm gravel lay hardcore to a depth of 110 mm around the entire periphery of the excavation.
Correct tamping of the gravel will ensure a neat nish of the excavation oor, and facilitate installation of
the supporting braces.
Remove the gravel at the positions shown in Figure 1 in order to create two 500 × 700 mm recesses
90 mm deep (as measured from the surface of the stone bedding). The recesses will accommodate the
steel braces, once imprisoned in the concrete, these braces will support the pool structure.

HOTLINE
WOODEN POOLS BWT myPOOL POOL’N BOX
Figure 1 – Positions of the recesses created to accommodate the supporting braces
4.2.4 Installing the supporting braces
Install the supporting braces in each of the two locations, having rst tted the recesses with jacks (Figure 2).
Use 2 double acting jacks,2 single acting jacks and 12 screws with a diameter of 10 mm (bag A). The top
screws should be inserted after the height of the bottom screws has been adjusted.
Figure 2 – Installation of the jacks under the supporting brace
The supporting braces must under no circumstances extend above the top of the pool wall (just
beneath the coping) after adjustment of the supporting brace jacks. On the contrary, it is not problematic
if the top of the supporting braces are 1 or 2 cm below the top of the pool wall.

2021/03 - Version: B Code : 37371
HOTLINE
WOODEN POOLS BWT myPOOL POOL’N BOX
After assembly, adjust the supporting braces and check carefully that they are correctly positioned: plumb,
level, correct alignment of the supporting braces. To ensure that the supporting braces stay in place after
adjustment, you can pre-seal them with a small amount of concrete.
TIP: You can use the supporting braces to visualise how high the concrete slab should be once it has been
poured. To do this, taking the top of the pool wall, below the coping, as level 0 (underneath the coping,
see Figure 3), measure 0.755 m and mark this distance on the front of the supporting brace. This mark will
correspond to the height of the nished concrete slab.
The height of the pool under the coping may be over 0.755 m if the moisture content of the wood is
high at the time of installation of the pool (wood stored in a humid or poorly ventilated area).
Take particular care while carrying out these assembly steps, they will determine the quality of the
pool nish. Incorrect positioning of the supporting braces may render assembly of the pool walls
impossible.
Check that all the dimensions quoted in Figure 3 are correct before proceeding with the next step.

WOODEN POOLS BWT myPOOL POOL’N BOX
4.3 Pouring the concrete slab
4.3.1 Rebar
Before pouring the concrete, lay the top layer of welded rebar mesh (type ST25C) over the oor of the
excavation (the mesh should be set back 3 to 5 cm from the edge around the entire periphery). Some
cutting around the supporting braces will be necessary.
The mesh should overlap by one and a half squares and should be connected together using metal ties.
The mesh should be raised using spacers to ensure that will sit in the centre of the slab. If you are using
self-levelling concrete, you should place a layer of polyethylene sheeting under the rebar mesh because
the concrete is very liquid and could ow into the spaces between the gravel. Use C25/30 grade concrete
as a minimum.
4.3.2 Slab dimensions
The characteristics of the concrete slab are provided in Figure 4.
While pouring the slab over the oor of the excavation, make sure that the upper rebar mesh is properly
encased in the concrete: the layer of concrete above the mesh must be at least 3 cm thick.
Refer to Figure 4 to determine the depth of the slab to be poured: it should be 150 mm thick.
Level and smooth the slab carefully to void surface defects that will have to be corrected later.
The slab provides seating for the wooden structure. Any levelling defects will become apparent when
the pool is lled with water. Similarly, signicant surface defects will detract from the quality of the
nish of the pool oor.
Figure 4 – Details of the concrete slab
The structural dimensions and measurements listed have a tolerance of +/- 3% (European standard
EN 16582-1). The AFNOR AC P90-321 agreement allows the following deviation in terms of depth:
For a depth greater than 1.25 m: +/- 3 cm

Assembly of the wooden structure may begin without waiting for the slab to cure fully, however, the longer
the delay between building up the wooden structure and lling the pool with water, the greater the risk of
deformation of the wood, particularly if the temperatures are high. You must wait at least 3 weeks for the
concrete to cure before lling the pool with water.
Before starting to assemble the wooden walls, make sure that the slab is free from any defects and that it
is perfectly level. The nish of the concrete slab will determine the correct seating of the walls, the quality
of the pool oor and the nish of the pool. A level defect will be accentuated and visible when the pool is

lled with water. It could also make it impossible to assemble the pool walls. If necessary, correct defects
by sanding or resurfacing the slab.
Your pool is comprised of several slat references, the positions of the slats are illustrated in Figure 5. There
are specic slats to house the pool ttings (skimmer, return tting). Assembly of this structure is described
step by step in this section.
5.1 Application of the bituminous strips
Start by unrolling the bituminous strip that will insulate the wooden structure from the concrete slab
(Figure 6).
Figure 6 – Laying the bituminous strips
5.2 Assembling the slats
After laying out the rst row of slats, make sure that the diagonals are equal.
Lay out the ½ slats that constitute the pool widths, then, in the corners, slot in the slats that constitute the
pool lengths.
Fit the slats together, according to the assembly diagram shown in Figure 7 and taking care to position the
machined slats correctly (see Figure 5). The tongues should always be oriented upwards, and the grooves
downwards.
The female slats and half-slats located on the top of the walls are machined to subsequently
accommodate the liner locking track. The machined section should be oriented towards the inside of
the pool.
While assembling the pool walls, make sure as of the rst rows that the slats are fully engaged in the
grooves.
For correct assembly, it may be necessary to use a mallet and clamp to remedy light slat deformations
caused by storage. Do not strike the wooden slats directly, use the protective martyr blocks (sections of
slat approximately 30 cm long, supplied.
After assembling the rst row, check that the slats are perfectly level, make any corrections necessary,
then screw the slats constituting the pool lengths together:
• x them to the 2 supporting braces (these are pre-drilled, as shown in Figure 8) using the 14 A2 SS
torx hinge screws 6 × 30 (bag C).
• screw them together as shown in Figure 9 using 2 screws per slat pair, and on the two sides
comprising 5 full slats and one half-slat, that is a total of 24 countersunk 5 x 40 A4 SS torx screws
threaded over 25 mm (bag B) .

Figure 8 – Fastening the slats to the supporting braces
The heads of screws inserted from the inside of the pool should be ush with the pool wall to avoid
damaging the liner.
The height under the coping of the assembled pool will only be 0.755 m if the moisture content of the
wood is normal and the slats are properly tted together.
The slat junctions must not coincide with the supporting braces.

5.3 Installation of the box reinforcements
Figure 10 – Position of the reinforcements in the box
On the last row of wooden slats, fasten 4 reinforcements in position using 2 countersunk torx screw 5x80
A4 SS torx threaded over 50 mm from bag H at each en, that is a total of 16 screws, at the positions
indicated in Figure 10.
5.4 Mounting the nishing trim on the supporting braces
Put the supporting brace nishing trims in position. They should be ush with the top of the pool wall.
Working from the inside of the pool, insert screws as shown in Figure 11 using 3 countersunk screws
5 × 80 A4 SS torx, threaded over 50mm (bag H) per half trim, that is a total of 12 screws. The 2 half trims
do not meet, the metallic brace will remain visible.

5.5 Mounting the coping brackets
Working from inside the pool, fasten the 8 wooden coping corbels in position using a SS torx countersunk
screws 5 × 80 threaded over 50 mm (bag H), as shown in Figure 12. Ensure that the top of the corbels
are ush with the top of the wall. Check that the corbels are perfectly level to facilitate the subsequent
installation of the coping.

5.6 Installation of the metallic coping brackets
The metallic coping brackets are intended to support the coping and allow their attachment. Make sure that
they are correctly located. Position them such that they are ush with the top of the wall and make sure
that they are aligned with each other and with the wooden corbels.
Fasten 4 metallic coping brackets from the fastening element kit (2 righthand and 2 lefthand) to the top of
each supporting brace.
Their locations are shown in Figure 13. Use 6 A2 SS torx hinge screws (bag G) per bracket, that is a total
of 24 screws.

In each of the corners, install 8 metallic support brackets (4 righthand and 4 lefthand), and 4 corner coping
brackets, as shown in Figure 13
Use 64 Torx hinge screw 6x20 A2 SS (bag D):
- 6 per hefthand and righthand bracket
- 4 per corner bracket
5.7 Wood sealant
Once the slats have been assembled, paint the ends of the slats in each of the corners with wood sealant
to help limit deformation over time.
This product is white on application, but becomes colourless when dry. Drying time is 2 to 3 hours. If the
temperature is high or the drying time is too fast, apply a second coat. Follow the safety instructions on the
container. Rinse the brush with water after use.
5.8 Finishing trim
Use 3 convex head nails, 2.8 x 60 A2 SS (bag F) to fasten the 10 pine nishing trims (dimensions 755 ×
70 × 45) to the edge of each wall. The nails should be evenly spaced. (Figure 14).
Figure 14 – Pine trim
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.
