• On non-stable land
  A good location allows you to save time and avoid limitations. The pool should be in a sunny spot and easily reached.
  The location of the pool should be free of tubes or electrical connections.
  Take into account that the best is to assemble the pool on a sunny day and avoiding high winds.

PACKAGING, CLASSIFICATION AND RECYCLING

• Some pool components are packed in plastic bags. To avoid all risk of asphyxia, never allow babies or children to play with these.
• Thanks for respecting the European Union Laws and collaborating in protecting the environment.

When you have installed your pool and all the components are assembled, we thank you for classifying and recycling all the packaging.

Carefully read, understand, and follow all information in this user manual before installing and using the swimming pool.
These warnings, instructions, and safety guidelines address some common risks of water recreation, but they cannot cover all risks and dangers in all cases. Always be cautious, common sense, and good judgment when enjoying any water activity. Retain this information for future use.

Non Swimmers safety
Continuous, active, and vigilant supervision of weak swimmers and non-swimmers by a competent adult is required at all times (remembering that children under five are at the highest risk of drowning).

• Designate a competent adult to supervise the pool each time it is being used.
• Weak swimmers or non-swimmers should wear personal protection equipment when using the pool.
• When the pool is not in use, or unsupervised, re-move all toys from the swimming pool and its sur-rounding to avoid attracting children to the pool.

SAFETY PRECAUTIONS

Safety devices

• It is recommended to install a barrier (and secure all doors and windows, where applicable) to prevent unauthorized access to the swimming pool.
• Barriers, pool covers, pool alarms, or similar safety devices are helpful aids, but they are not substitutes for continuous and competent adult supervision.

Safety equipment

• It is recommended to keep rescue equipment (e.g. a ring buoy) by the pool.
• Keep a working phone and a list of emergency phone numbers near the pool.

Safe use of the pool

• Encourage all users especially children to leer how to swim
• Learn Basic Life Support (Cardiopulmonary Resus-citation – CPR) and refresh this knowledge regularly. This can make a life-saving difference in the event of an emergency.
• Instruct all pool users, including children, what to do in case of an emergency
• Never dive into any shallow body of water. This can lead to serious injury or death.
• Do not use the swimming pool when drinking alcohol or using medication that may impair your ability to safely use the pool.
• When pool covers are used, remove them completely from the water surface before entering the pool.
• Protect pool occupants from water related illnesses by keeping the pool water treated and practicing good hygiene. Consult the water treatment guide- lines in the user’s manual.
• Store chemicals (e.g. water treatment, cleaning or disinfection products) out of the reach of children.
• Signage is to be displayed in a prominent position within 2 m of the pool.
• Removable ladders shall be placed on a horizontal surface.

WARNING:
Every electrical appliance fed in 220 V, has to be located at least at 3,50 m from the edge of the pool. The equipment should be connected to a voltage, with earth connection, protected by a residual current device (RCD) having a rated residual operating current not exceeding 30 mA.

COMPONENTS
Draw and classify all components included before assembly. It’s time to assemble the ladder and the pump, follow the respective instructions. Kits with missing parts will be covered by the warranty only if reported to the after-sales service within 15 days as from the date of purchase of the swimming pool. In order to avoid any possible injury all swimming pool walking entrance must be regularly checked.

Locate the model of your swimming pool in the following table and verify that the number of UNITS within each box or container matches this table ( *for the kits ).

PREPARATION OF THE SITE

This is a determining stage in the construction of your pool. Certain works performed in situ, like the preparation of the land, the concrete slab, the draining… could need the intervention of professionals that will suggest the most adequate solutions.
Select the ideal location, in the sunniest spot possible, taking into account the local regulations (distance from the paths, public rights of way, networks…) and the landscaping after installing the pool.

Your pool can be installed in these three ways: A-B-C

Try to not install your pool on recently filled land or unstable land. Whatever type of installation you choose, you should excavate and prepare the land for levelling.
Attention: in the case that the land is sloping, you need to excavate it for levelling. Do not add soil to level it.

• In the case of assembling your pool above ground, you can use either a bed of sand or a concrete slab. If you choose the bed of sand, use fine and clean sand, otherwise you could stain the liner due to there being algae.
• In the case that the pool is semi in-ground or completely in-ground, the installation should be using a concrete foundation slab. If a foundation concrete slab is used this should be at least 15 centimeters thick. The pool is assembled after the concrete foundation slab has completely dried (3 weeks). The filter group should be located below the level of the pool and ideally at the floor level of the pool.

PARTIAL OR COMPLETELY IN-GROUND INSTALLATION
According to the nature of the land, you should install a peripheral drainage and connect it to a decompression well. The well will be excavated before the construction of the pool to avoid that the excavations fill with water during the works. It should be near the pool, a few centimeters lower than the deepest point of the same and reach up to the surface. The decompression well is located at the most humid point. It acts as an overflow in the case of water infiltrations or clay soil, starting from the fact that water rises quicker through a tube than through the soil.

Installation place:
Our pols are designed to be erected above ground an for an outdoor family use. The ground has to be firm, flat and perfectly horizontal. Remember: 1000 IIs of water = 1 ms = 1000 Kgs.

Advices to chose the best location for your pool:

• Select a place where you’ll have to realize the least excavation to levelled the ground.
• Non easily inundated area in case of rain. Where there is not any underground confection (water, gas, electricity,..)
• Do not install it underneath electric line, Protected from wind and without any trees because the pollen and the leaves make the pool dirty.
• Sunny area, where the most sun is during the morning. Close to a water and power supply and drainage system.

UNACCEPTABLE LOCATION: Sloping, uneven ground. Sandy, rocky or soggy ground.

Mark the installation area: Identify your pool model in this table for the dimensions needed for installation.
To mark the ground, use wooden stakes, a screwdriver, funnel or plastic bottle and flour or lime. It is essential to level the total surface necessary before the marking to ensure the correct pool installation. Check the table to mark the location of your pool, as centered as possible in the rectangle.

For the assembly of this pool, you have two options:

• A – Install the pool directly on the ground (PAGE 37).
• B – Prepare a concrete base, with the measures indicated in the table. (PAGE 43).

NOTE: IT IS RECOMMENDED OPTION B.

Tool necessary (not included )

INSTALLATION

OPTION 4A: INSTALLATION OF THE POOL ON THE GROUND – Levelling: When levelling the ground, we will always remove the excess of soil and never add it to where is missing: this will ensure greater ground stability and firmness. Always remove all grass, roots, stones, etc. Levelling is extremely important: devoting the necessary time and effort to ensuring that your pool sits properly on the ground will avoid problems later.
How to level: thanks to a large mason rule (aluminum or wood) and a level, level out the ground forming rectangles (or squares), locating the strip in the selected and cleaned area. When all the areas are on the same level and when the excess of ground is removed, you may fill in the small areas which are left to level out (with clean ground or sand) but always compacting and levelling again afterwards. It is very important that the installation area is well compressed and firm so the pool doesn’t bury when its full of water. Please ask a professional: builder, gardener,…

Tool necessary ( not included)

OPTION 4A: INSTALLATION OF THE POOL ON THE GROUND.
Finishing: On the cleaned and levelled ground, spread a light coat of sieved sand (max. 1cm).
Water and compact it (with a garden roller). Check that is well levelled. Do not use the sand to level the ground.
To install the pool properly, the finishing has to be perfectly leveled.
If it is not the case, the different pressure differences on the contour might deform the stakes, or even make them split .
Also, the water which would spread may damage the environment, or even cause accidents.
Check again all the area level before beginning the following process: the assembling success depends on that phase quality.

Tool necessary ( not included)

Instructions for installing oval pools: KPCOV52(L), KPCOV66 (L), KPCOV88. Not valid for the octagonal pool.
If you have an octagonal pool, go to page 44.
Pool Installation: It is advisable that the pool is installed by two or more adults.
For your safety, it is recommended that you use gloves. Avoid windy days.
Perform all of these steps on a firm, level ground before digging the respective trenches.
Realization of the ditches (Z): depending on the pool model, dig the trenches according to the drawings.
Dimensions of z = length x width x depth.
From the center of each trench the distance between one ditch and another, (z1, z2, z3) is 140 cm.

Mounting of the columns (C) and the interior structure:
1º- Mount each column with the following parts:
1 PV1185 + 4PEAO + 1 PG + 2PEU2 + 1PEU with the “TV” screws, as shown on the next page.
2º- Join the “E” crossbar to the “C” column through the “PEU” parts. Screw studs with the “TV” bolts, nuts and washers. 3º- Join the “A” crossbar + the second “E” crossbar, with the “TV” screws.
To complete assembly of the structure, join the other “C” column, as shown in this picture.
4-Place a plate AP so that the two holes coincide with the two holes in the part PEU (the closest to the PV1185). Then place the other part AP and fasten it using 2 TM640 screws. (Before fitting the plates AP it is best to introduce the assembled beams in the ditch already prepared).

Beam assembly
Perform all of these steps on firm, level ground. It is important to perform assembly of these parts in a wide and level space for greater convenience.

1. Place the “PEU2” piece so that the 4 holes in each one of the sides, match with the second and third row of holes of the PG (See photo 1b). The side with two holes must be on the top. Do not screw the “TV” until the PEAO parts are in place.
2. Place 2 pieces “PEAO” on each side from the outside of the PG crossbeam and screw them (with TV screws and number 13 key). Then put the PV1185 piece into place. Insert another PEU2 piece from the top to the bottom of the PV1185 column, until it reaches the “PG” piece. Then, secure it with flat screws through the “PEAO” pieces.

Place and install the crossbars in the trench.
Before fitting the plates AP it is best to introduce the assembled beams in the ditch already prepared.
Fill with soil, compact and level it.
Check the level of the columns (correctly leveled) (N).
The base of the structure should be completely covered ( 2 cm of sand over the base of the PEAO piece ). To do this, use a thin layer of sand and compact it as much as possible.

OPTION 4B: INSTALLATION OF THE SWIMMING POOL IN CONCRETE SLAB

• Prior to installing the pool, you need to create a reinforced concrete slab which is a minimum 150 Kg/m³ of 15 cm thick. It must be a perfectly flat and horizontal slab.
• Perform a small excavation in the form of a rectangle, according to the measurements of the table.
• Before pouring the concrete, for the KPCOV52(L), KPCOV66(L) and KPCOV88 models, you must place the structural system perfectly leveled (columns and interior structure, beams). Page 39.
• The distance between the center of the columns is 1400 mm
• Once the structure is in place, the mesh can be placed on top.
• Be sure to immobilize the structure so that when the concrete is poured it will not move.
• The base of the structure should be completely covered ( 2 cm of concrete over the base of the PEAO piece ).

KPCO41:
Once the floor or the ground have been properly leveled, the ground will be marked with lines where the inside face of the swimming pool panels will be placed.
It is time to check the measurements.
If not, the task needs to be performed again.

KPCOV52(L):
Once the floor or the ground are properly leveled, the ground will be marked with lines where the inside face of the swimming pool panels will be placed.
We start by marking the axis of the buried beam in the floor. We take as reference the center of the column and with a tape measure we draw a line to the other column. Now, we make a mark in the middle of that line. This mark represents the center of the pool. Now we draw another line perpendicular to this one. This will be the longitudinal axis. We form the rectangle on the image. It is time to check the measurements. If they are not correct, the exercise needs to be performed again.
Important: The longitudinal lines must have 4 cm of separation with respect to the column ( 4 cm = space for panels).

We start by marking the axis of the buried beams on the floor.

PLACEMENT OF THE PANELS

• All pool panels are identical except the one that carries filtration. Place it in the center of one of the two longer areas of your swimming pool.
• The inside face of the panels (smooth surface) must be above the polygon just marked in the previous section.
• Use the vertical profiles to join the panels together. It is recommended that the plastic protecting the profile on the inside is removed before mounting the panels.
• It’s very important to move the panels with great caution and between two people.
  The marks or scratches caused to the panels due to poor handling are not covered by the warranty. If you have problems inserting the profile, move the panels until they have the same angle and distance as the profile. The profile will thus enter more easily.
  Note: if your pool includes a led projector (KPCOV66L) check page 63. it is important to thoroughly read the instruction manual of the spotlight before installing the liner.

PLACEMENT OF PANELS IN THE STRAIGHT AREA (oval pools)

• The union of the panels must stay in the center of the column. That way you can insert the profile ( photo 3 ).
• In picture 4, it is possible to see how the panels are not centered in regards to the column. Avoiding this is very important in order not to encounter problems when filling with water. If this occurs, you will have to distribute the distances between them so that they are as centered as possible.
• It is normal that there is space left between the panels and the columns ( photo 5 ). When you fill the pool with water, the panels will touch the columns due to the force of the water.
  It is advisable to begin installing the pool in the curved area (this way, the panels will be fixed on their own).

PLACEMENT OF THE TOP RAILS
Now is the time to remove the outer protection of the vertical aluminum profiles

Octagonal Pool: All the top rails are the same shape, except for one, which has a flat surface (photo 7). This copings must be placed above the filtration. The piece can be found in the

PLYCOMP112SK box. Please check the position of the skimmer with the copings.
Oval Pool: In the diagram it can be seen that there are 5 different types of copings. Identify the parts according to your pool.
Inside the PLYCOMP112SK box is the copping for the filtration panel. (Photo 7).
It is fundamental that the pieces are levelled to avoid future problems when positioning the metal trimming. The main cause can be due to an incorrect levelling of the terrain. We suggest supporting the copping from outside of the pool at the joint of the vertical metal profile.

IMPORTANT: Only in the case of contacting with the after-sales service due to an incident.

1. Locate your pool in the following tables
2. Search for exact piece needed Check the drawing.
3. You must consider that each reference refers to a single piece, one unit.

PLACEMENT OF THE SKIMMER

• Completely assemble the skimmer and screw it from the inside of the pool.
• If you find it difficult to screw it to the wall, you can use a 2 mm drill bit and make a guide for the screw. This will make the work easier.
• With the glue, place the seal facing inward. This is very important in order to set the plastic sleeve properly and prevent water leakage. Photo 10.

PROTECTIVE GROUND BLANKET

• It is recommended the duck tape be used to cover the rivets of the vertical profiles, which will be in contact with the swimming pool liner. This prevents the liner from being pricked. (Photo 11).
• Before covering the ground, it is advisable to sweep and vacuum the concrete floor to remove dirt, such as pebbles, branches, leaves, etc.
• Place the cover to protect the sleeve. Remove any remaining wrinkles so that they do not appear once the pool fills with water.
• Cut the cover according to your swimming pool model, adapting it to the shape of your swimming pool.

PLACEMENT OF THE SLEEVE ( LINER )

• If your pool includes the LED light, check the assembly manual before installing the liner.
• Remove the sleeve from the box with great care. Stretch and extend it in the shade so that it recovers its shape. Perform this step at least two hours before its placement. The ideal temperature for mounting the sleeve is 25 – 30°C.
• Do not use sharp objects they could prick the sleeve. The warranty does not cover punctures due to poor handling. Take off your shoes.
• Extend the cover, pulling it to the corners of the swimming pool. It is very important to take this step seriously, since the final aesthetic of your pool will depend on proper placement of the sleeve.
• Insert the sleeve in the attachment slot. If at some point during completion of this operation an excess of sheath is observed on the wall, spread the excess out evenly around the perimeter of the pool. This will prevent wrinkles.
• Once in place, fill the pool with 2 – 3 cm of water and extend the sleeve wrinkles well. If folds remain in the bottom is not a reason to replace the sleeve with another, as it is not a manufacturing defect. Take your time.
• Very Important: ( * ) Locate the serial number on the upper part of the wall of the sleeve, near the weld that joins the side.

• Maybe the liner does not perfectly adjust to the corners of your pool. This is not a structural problem, simply aesthetic. Do not be surprised.
• When you start to sill the pool, remember to fill only up to 2-3 cm and remove all the wrinkles on the bottom from the interior, without any footwear. Also, you must adjust the corners at the bottom and sides of your pool. It is important that the liner is well distributed around the pool sides and perfectly fitted.
• If this problem occurs, tray assembling it on a very sunny day with high temperature.
• In order for the liner to fit better in the corners of your pool, it is advisable to heat the liner, e.g. with a hairdryer at short intervals of time.

INSTALLATION OF THE COPPING’S TRIMS
This piece covers the joints of the copping (there must be a space between the copping). It is aesthetic.
Possibly and due to irregularities of the terrain the trim does not fit completely. If this happens, do not worry because it does not affect the structural system. In that case we suggest using double faced tape or Velcro.

• Look for the trims. All pools have trims with angular shape. Place them in the copping’s connection (photo 15)
• Oval pools have trims for the straight area. The ends are different. Place the longest part on the inside of the pool. (photos 16 and 17).
• Screws are not necessary.

INSTALATION OF THE STRUCTURAL SYSTEM TRIM
This step is only for oval pools.
This is to cover the vertical pols (photo 18) to give the swimming pool a nicer aesthetic. This piece is for decoration only.
Look for some brackets and screws (4 x 16 mm) that you will find in the bag KITENV.
Screw the bracket as you prefer. In photo 19 there is an example. Two screws for each bracket is enough.

FITTING THE RETURN VALVE (V): (IMPELLER NOZZLE: V) This valve is located at the bottom of the pool wall, and the water is returned to the pool through it after being treated in the treatment unit. Start pouring water into the pool through a garden hose, and stop 4 cm below the bottom of the valve hole. Mark the position of the hole on the liner with a felt pen and make a cross- shaped cut in the center of the mark with a Stanley knife or similar. Do not cut beyond the edge of the hole (Photo 21). The liner can also be cut before introducing the nozzle, making a circular cut supported at the back on a flat surface.
Locate two return valves of the skimmer box. One valve has a flat finish, which can be used with the hose provided in the kit of your pool. The other return valve has a threaded finish. This should be used if you want to install a semi-rigid PVC pipe (not included). In this case, you will need a coupling to change from 38 mm diameter to 50 mm diameter. This can be found in your nearest DIY store.

Insert the nozzle from the inside of the pool through the cut already made with a friction ring (F) and a gasket (J) once the are placed. This way, the gasket (J) is in contact with the liner. Cut the piece of the liner that is visible from the outside (Picture 22). The other gasket (J) is put into place from the outside, place it at the very back in contact with the liner (Photo 23). Place the other friction ring (F)l (Photo 24) and tighten firmly with the nut (T). (Photo 25)
To properly insert the nut from the exterior, the person located inside the pool holding the return valve, should slightly move backwards to fix the nut with the composite form the exterior. (photo 25 – 26)

Insert the return hose (M) which goes from the outlet of the treatment unit to the return valve (V), and secure it with the clamp (A) (photo 27). When the filtering is working, the safety cover must be installed as seen in photo 28. Use the screws included in the kit.
Tip: You can use a 2 mm drill bit to make a guide on the panel, this way it is easier to screw it. It is advisable that it is attached once the filtration has begun. This way you can correct any problems you have with the filtration without needing to remove the trim.

ATTACHING THE SKIMMER BODY (S) TO THE OUTSIDE OF THE POOL:
Fill the pool with water until it reaches 4 cm from the bottom of the die of the skimmer. Affix the seal ring and position the skimmer frame. Screw it with a screwdriver. Using a Stanley knife, cut the bit of the liner (L) that the skimmer frame covers (only the inside bit).
Finally, place the trim piece. Note that the trim has “max” and “min” markings. They indicate the maximum and the minimum level of water that your pool should have. Cover the connecting bushing (C) and the water treatment unit with Teflon. Screw the connecting bushing (C) tightly to the skimmer and connect one end of the hose to the skimmer connecting bushing (C) using a clamp (A). Then fit the other end to the treatment unit and clamp it.
Important: Use Teflon on all water hose connection threads to ensure leak- tightness.
Locate the aluminum trim for the skimmer. To secure it to the panel, take 8 screws (4 x 16 mm) from the box: KITENV…..

PLACEMENT OF THE INTERNAL LADDER

• Take out the ladder and follow the installation instructions. Think about where you want to have the entry for your swimming pool. You can also mount it and put it into pool without attaching the fastenings to see how it looks. Just support it on the shore.

• Look for two metal plates. These parts are essential to correctly affix the ladder.
  Put them on place panels (photo 33) and make a hole from the bottom using the proper drill bit Nº 10 (photo 34).

• Place part 8, the fastening, so that it coincides with the hole. Use the short bolt and secure it with a nut and washer. (photo 35).

• Finish securing the plate by making another hole and securing it with a long screw bolt. (photo 36).

• Once one of the ladder’s fastenings is secured, introduce the other fastening. Make a mark where the screw hole should be made. This step is very important, as it must match the distance between the ladder rails.

PLACEMENT OF THE EXTERNAL LADDER

• Remove the ladder from the box with great care. Look for 8 screws (3.5 x 25 mm) and two hooks in the box: KITENV…
• Place the ladder against the pool wall (photo 37) and make a mark as shown (Photo 38). Measure 2 cm from the ladder and 1 cm from the marks of the panel.(photo 39). Here you will make the upper hole for the hook. It should look like the (photo 38).

Look for the hook and insert it as shown on photo 40. Follow the same procedure to secure it to the handrail (photo 39).

NOTE 1:

• KPCOV66L: Your pool consists of 10 standard panels, 1 filtration panel and one led panel. We recommend one of these 4 options at the time of placing the led panel. This way, the light will spread throughout the pool evenly.
• KPCOV52L: Your pool consists of 8 standard panels, 1 filtration panel and one led panel. We recommend one of these 4 options at the time of placing the led panel. This way, the light will spread throughout the pool evenly.

NOTE 2:
INSTALLATION OF THE LED PROJECTOR STRUCTURAL SYSTEM
It is about covering the led projector and the cable as we did for covering the structural system. Locate the piece and put it as shown in picture A.
The structural system is composed of 4 brakets and its respective screws.
ATTENTION! It is very important to place the brakets IN THE STRIPPED AREA of the panel as shown in picture B. If, for the contrary, you try to screw the brakets on the flat surface, you won´t be able to screw them properly and the panel may damage.

FILTER

ASSEMBLY SUGGESTIONS:

• The filter should be located at least 3.50 m from the pool.
  The following diagrams explain the movement direction of the water. Check the manual that comes with the filter group for the assembly instructions.
  Note: Fill the filter with 2/3 of clean, calibrated sand: only one calibration is supplied guaranteeing good use of the filer.

  1. The colours and connections of the filter can vary according to models.

Check the specific manual
The multi-directional flap determines the flow direction. The marks “PUMP”, “RETURN”, “WASTE” are engraved on the inlets and outlets of the pump. The installation of all the electrical systems should comply with the NF-C15-100 regulation. Check with the manufacturer for any modification of one or several filter system components. The suction pump should not be situated above the water level, because there is a risk of becoming deactivated.

All the threaded connections should be assembled with the watertight Teflon tape *, except the connection with O rings. The Teflon should be wound round the thread in a counter clockwise direction.

LAND-FILLING: Finish filling the pool. The water level should be situated between the upper third part and the second half of the skimmer mouth.

SAND FILTER
This is the oldest of filtering systems. The filtered water passes through the sand (calibrated silicon) that retains all impurities. This type of filter is equipped with a multi-directional flap that allows easy manipulations and cleaning.

*DIFFERENT POSITIONS OF THE MULTI-DIRECTIONAL FLAP (4 OR 6):** When you perform changes the position of the multi-directional flap that pump should always be stopped, without risking seriously damaging the filter and cancelling the guarantee.

1. FILTERING POSITION (OR FILTER): Usual position of the flap that allows the water coming from the pump to enter through the upper part of the filter and circulate through the sane, where all its impurities are trapped. The water is collected in the mesh at the bottom and returned to the pool. The pressure gauge situated at the upper part of the filter allows controlling the pressure. In the case that the pressure increase 0.2 bar regarding the starting pressure, you will need to clean the filter.
2. WASHING POSITION (OR BACKWASH): Sand washing position. Allow the water to circulate in reverse direction in the filter. The water enters through the lower part of the filter elevates the filtering mass and therefore collects all its impurities and because they are lighter than sand, they area evacuated through the upper part of the filter towards the drain. This operation should last between 2 and 3 minutes.
3. RINSE POSITION / DRAINING OF THE FILER (OR RINSE:** Operation that follows washing the filter. When you have cleaned the filter, you should rinse and re-compress the filtering mass. In this position the water circulates through the filter as in the filtering position but is evacuated through the drain at the filter outlet. This operation should be performed between 20 and 30 seconds.
4. EMPTYING POSITION /DRAIN (OR WASTE);: Position to evacuate the water of for emptying the pool. In this case, the water does not pass through the filter, it goes directly to the drain.
5. CLOSED POSITION (OR CLOSED): This position does not allow the water to pass and is used to put the pool into complete wintering when the filtering stops.
6. RECIRCULATION POSITION /CIRCULATION
   *: Position used so the water circulates through the hydraulic network without passing through the filter. This possibility iS Used to move the water if you want to add a product to the pool or if you should perform any operation in the filter, because in this case the filter is isolated and the water coming from the pump is directly expelled.
   Some models are delivered with 4-way flap (available options: Filtering, Washing, Emptying/drain Closed or wintering),.
   ** These positions refer exclusively to the 6-way flap. You should never manoeuvre the multi-directional flap when the pump is working.

MAINTENANCE AND USE

RESPECT THE ENVIRONMENT
DO NOT TAKE APART THE POOL UNLESS IT IS STRICTLY NECESSARY. IF YOU DO SO, PLEASE REUSE THE WATER. WATER IS A SCARCE GOOD.

When your pool reaches the end of its useful life, it should be disassembled; the different materials (plastic and steel) should be separated and taken to the disposal point indicated by local authorities.

MAINTENANCE AND USE:

• Switch on the filter system once a day in to insure a complete water volume renewal and never do it when somebody is in the pool (see filter manual).
• Check the filter’s level of clogging regularly in summer when the pool kit is in use.
• Check screws, nuts and washers (for rust).
• The pool water level has always to be hold in a minimum of 15 cm from the pool superior edge.
• Never empty the pool completely. Low water levels may cause serious damage to the pool.
• Failure to comply with the maintenance instructions may lead to serious health risks, especially for children.
• The use of a swimming costume entails respect for the safety regulations set out in the maintenance and user guide.
• Never leave a pool kit empty on the ground, outdoors.
• Clean regularly the P.V.C liner and the water level mark with non-abrasive products. Regularly clean the fold joining the bottom to the side of the liner, as it is an area where dirt accumulates. If you do by accident a small hole in the liner, you can repair it thanks to our rubber patches AR202 or V12.
• The isothermal covers (for the summer) protect your pool from insects, dust, leaves,… and avoid to loose the water temperature. Do always set it in order the bubbles are in contact with the water.

WINTER-SEASON:
A) IF YOU CHOOSE NOT TO DISMOUNT THE POOL:

1. Clean the liner bottom and sides with a non-abrasive product.
2. Treat the water with a chemical product for wintering. We recommend using LIQUID WINTERISER instead of floats with solid product to avoid discoloring the liner.
3. Leave the pool full of water considering:
   • For pools with skimmer and refilling pipe, reduce the water level 5 cm underneath the skimmer and close the refilling pipe with the screw tap which is included with the filter.
   • For pools with exhaustion and refilling pipes, reduce the water level 20 cm from the superior edge of the pool and close the pipes using the screw system incorporated.
4. Disconnect the pipes. Do not dismount the skimmer and the refilling and exhaustion pipes.
5. Protect the pool with a winter cover, and put a floating element between the cover and the water, in order to protect it from frost.
6. Filter: disconnect it from the pool. Clean it, empty the sand or remove the cartridge, dry it and keep it in a covered and sheltered from dampness place.
7. Accessories: remove every accessories (ladder, alarm, spotlight, pole…), rinse them with soft water and tidy them away.
   TO RUN THE POOL AGAIN: Remove the winter cover, install the filter, change at least 1/3 of water and realize a chlorine treatment. Switch on the filter for at least 8 hours in an uninterrupted way, respecting the continuous working period indicated in the filter manuals.

B) IF YOU CHOOSE TO DISMOUNT THE POOL:

1. Empty the pool. Measures: Filter, Automatic pump for handling clean water or communicating vessels system. Communicating vessels system: Use the hose from your filter with the smallest cross-section. Fix a weight to one of its end and plunge it into the swimming pool. After this, sink the whole hose, until there is no air inside. With one hand, and under the water stop up hermetically the end of the hose and take it to the emptying point. Remove hand, and water will start running. Do not use this water for watering the plants, because it contains chemical products.
2. Clean every pool constituents with a sponge and a soap product with a neutral pH. Dry them and tidy them away in a dry and clean place. That’s normal that after having installed and dismounted the pool several times, the P.V.C liner dilate and loose its elasticity.

TO RUN THE POOL AGAIN: Read another time this manual instructions from the beginning.

CHIMICAL MEASURES:
Please read carefully the chemical product manufacturer instructions.
WARNING: Keep chemical products in a clean, dry and out of children place. Important: Every products used have to be compatible with the P.V.C liner.

• First filling: Analyze the water pH and chlorine (Cl) and adjust them to the optimal levels: pH: 7,2 – 7,6; Chlorine: 0.5 – 2 ppm.
• Chlorine treatments: Consist in increasing the chlorine level until approximatively 20 ppm to eliminate germs and seaweeds. This process has to be done only when the pool water comes from rivers or ponds, … or if it stayed a long time without any treatments.
• Checking: Check at least once a week the chlorine levels (use a chlorine and pH analyzer). In the same way, we advise to add an algicide to prevent seaweeds appearance. Never have a swim before the chlorine level stabilization. Do always use a floating dispenser for the chemical product (tablets) dissolution. The chemical product measuring out has to be done in accordance with: Your pool water volume, the bathe frequency, the climatic conditions, the water temperature and the location. Do always move the water and wait for the chemical product dissolution before adding another one. Wait approximatively 12 hours between any pH, chlorine or algicide adjustment using the filter system.

MECHANICAL MEASURES:
Check the filter, the skimmer, the valves and the pipes are well connected to the pool. Do consider high water temperature will involved more time for the filtering. Theoretic filtering time = Water volume / Filter system discharge (generally 8h/day with water temperature of 21°C), (Ideal: 2h in the morning – 4h around midday – 2h in the afternoon). PLEASE RESPECT THE CONTINUOUS WORKING PERIOD INDICATED IN THE FILTER MANUALS.

VACUUM CLEANER (MANUAL OR AUTOMATIC):
Only for pools with skimmer. Connect an hose extremity to the brush head and immerse it into the water to make it fill in. Connect the other pipe extremity to the exhaustion adapter (TA) and place it above the skimmer basket. Switch on the filter in the FILTER position and begin to clean the bottom. Pay special attention to areas with folds where dirt accumulates.

BOTTOM CLEANER VENTURY STYLE:
Connect a garden hose to the bottom cleaner join and introduce it into the pool. Open the tap until a normal pressure to make the water flow out against the bottom of the pool, producing in that way an ascendant stream which leave the dirt into the filter (bag) which is adjust on the bottom cleaner.
