Installation Instructions
HOW TO USE THESE INSTRUCTIONS
Be sure to read these instructions completely before
beginning the installation of your pool. ATTENTION:
Always use these assembly instructions to install
your swimming pool. Ignore any English instructions
included with the pool, as the size will be in inches, etc.
ATTENTION: Check the pool parts with the English
parts lists.
These are installation instructions for the installation of
several sizes of round pools. Use the pool parts list and
extensive illustrations to identify your pool parts; then
read these instructions and follow the steps that pertain
to your pool assembly.
Doughboy cannot be held liable for damage caused by
careless or improper installation. Your warranty is void
if the pool assembly and installation instructions are
not followed exactly, or if the pool design is altered in
any way.
Contracted Installation
Doughboy is not affiliated with any professional pool
installers and cannot assume any responsibility for
installation mistakes made by the homeowner. If
the pool is installed by others, please supervise the
installation and make sure that the correct installation
method is applied.
Change of pool design
Doughboy expressly reserves the right to change or
modify the design and instruction during the course of
our manufacturing procedures, without incurring any
obligation or liability to reapply such modifications on
products previously or currently sold.
CAUTIONS
1. Do not attempt to install pool wall on windy days.
An unsupported pool wall can easily blow down and
may thus cause personal injury.
2. When assembling your pool, keep the parts not
currently used in an area out of the way. Unpacked
parts are easily tripped over and may be damaged
or cause personal injury.
3. Do not attempt to lift the heavy boxes by yourself. To
reduce the possibility of personal injury, have some-
one help you move heavy boxes (pool wall, liner, etc.).
WARNING
1. Your pool must be level within 2-3 cm all around.
An unlevel pool may cause excessive stress on
the pool frame. A pool which is not level may
cause a lot of pressure on the frame. This may
result in pool failure which could cause serious
personal injury.
2. Your pool must be on undisturbed soil, preferably
filtered sand. Filled up sand, sudden slopes within
15 cm or the water runoff may cause a cave in of
the subsoil. This could cause pool failure and may
cause personal injury.
3. Always install the Warning Sign. The decal is
designed to warn you, your friends and loved ones
that your pool is to be used for swimming and wad-
ing only. Do not allow any form of horseplay in or
around the pool. Failure to follow this warning can
lead to severe personal injury. Read the “Safety
First” booklet (in English).
4. Use stabilised sand as a pool cove. Common sand
can easily erode and allow the pool liner to rupture
which may cause pool failure or personal injury.
5. Secure your pool when not in use. Ladders and
gates should be secured to reduce the possibility
of unauthorised entry and possible serious
accidents.
6. Always repair liner leaks. Continued leakage
between the pool wall and liner can cause wall
damage to the wall which eventually may result
in pool wall failure. This could result in personal
injury.
7. To reduce the risk of possible electrical shock,
never install your pool under overhead wires.
8. Do not alter your pool as this may cause pool fail-
ure. Your warranty is void if the pool is altered.
9. Do not install a diving board, pool slide or any
other recreational accessories for use during div-
ing, sliding or jumping into your pool.
10. ATTENTION: Do not install the pool liner at tem-
peratures under 16ºC. At lower temperatures the
liner’s elasticity is too limited for proper installation.

POOL LAYOUT
Step 1
By means of the plan you determine the layout of the
clearance. Locate stakes A and B (in accordance with
indicated dimensions) and make from there 2 circles
for the clearance.
GROUND LEVELING
Step 2
Clear and level the pool area in the clearance as indicat-
ed. For a firm ground it is better to remove high points
than filling in low spots. Remove sods, stones, roots and
other objects that could puncture the liner. The entire
assembled pool framework must sit on flat ground.
STAKES AND STRING LINES
Step 3
Locate 4 stakes C, D, E and F in accordance with indi-
cated measures of the plan of your pool. Attach strings
between C and D, then E and F. Now mark the assem-
bled side supports, as indicated on the plan.

INSTALL WALL JOINTS
Step 11
The wall joints overlap (see plan). If joint piece doesn't
slide on easily, correct the side supports until the joints
fit perfectly. See to it that the round shape is preserved.
Connect the wall joints by means of the bolts and
screws included in the packaging. Attention: the
screwhead must be on the inside of the pool. Smooth
the screws. Fix the protective strip with tape.
INSTALL VERTICALS & END CAPS
Step 12
Install the verticals, so that the screw aperture is at
the front side on top of the vertical. The construction
is connect by screws. Position vertical end cap over
vertical (see plan). A drop of oil on the screws
facilitates your work.
INSTALL BOTTOM RAILS
Step 9
Slide the bottom rails into the vertical end caps, groove
up (see plan). Start on opposite sides of the side vertical
assemblies with the end rails stamped with 12". When
the bottom condition is not optimal, place a patio block
under every vertical end cap (sunk on bottom level for
extra certainty).
INSTALL WALL
Step 10
Remove steel pool wall from carton. Note ‘Up’ arrow on
wall. Determine starting point of wall from preliminary
planning, depending on the place of the pump and the
filter. The skimmer opening will be at the inside end of
the wall coil. Always start with the center of a vertical
end cap. Always uncoil 1,5 m and insert bottom edge
into groove in bottom rails. When the ends of the pool
do not connect completely, correct this by telescope the
bottom rail more or less into the vertical end caps.

COVE
Step 14
Important step: Make on the inside of the steel wall a
slant elevation of sifted earth of around 15 cm high and
wide. This is a vital structural element that prevents
water pressure from forcing the pool liner out under the
bottom rail.
LINER SEAM POSITIONING
Step 15
Check the pool floor again for stones, glass and other
sharp objects. Fill in all footprints and other unevenness
on pool floor. As floor sealing and extra protection of your
liner it is advisable to cover the floor with water-resistant
underlay, that you can fasten with tape to the underside
of the steel wall. Now place the liner on the top rail and
check as indicated.
Note: The embossed side of the liner will be the water
side.

STRETCH LINER
Step 16
Work in both directions with unfolding the liner and drape
it over the top rail and down the sides for about 60 cm.
The liner should be about 40 cm above the pool floor
in the center only. The bottom edge seam of the liner
should be inside the pool about 30 cm from the top rails
(see plan).
FILL POOL
Step 17
Before filling the swimming pool, hold the liner in place
by attaching two binder clips over folded cardboard on
the underside of each top rail. Because of the water
weight, the liner will be stretched with no wrinkles. Check
during filling the pool the liner for extreme tautness.
Binder clips do not self-release, so release binder clips
with extreme tautness and allow the liner to feed back
bottom liner seam
cardboard
clamp

binder clips
into the pool until the desired tautness is achieved and
re-clamp the binder clips. Remember that you are
monitoring a minimum tightness of the liner over rail that
will control the liner seating itself against the pool floor
and up the side with no wrinkles. When the water (5 cm)
is covering the pool floor, the liner on the pool floor must
be without pleats and wrinkles.
If this occurs, pull and lift the liner wall just enough to
stretch out wrinkles or pleats by the water weight. There
should be just barely enough tension on the liner, until
the floor is filled with approximately 20 cm water and the
liner is connected against the metal wall.
The clamps can be bought at several tool shops
(Preferably use synthetic clamps).
CONTINUE FILLING POOL
Step 18
After the pool is filled, the bottom liner seam of the
liner must be totally around in the pool must be close
to crossing of the bottom wall. Do not worry about the
strength of the liner, the strength is calculated on
1,5 x the original size. When the bottom liner seam is
not on the right place, there is a chance that you have
not enough liner left to place on the top border, so that
you have to start again with placing the liner.

PROCEDURE TO ATTACH LINER
Step 19
With the help of two or three people, raise and hold the
liner up from any three top rail sections. Be careful and
never allow the liner to fall back into the pool. When 1
man is holding the liner, the other folds back the vertical
end caps, the top rails and top connectors from three top
rails (see plan).
INSTALL COPING AND
STABILIZER RAILS
Step 20
Make a return hem as illustrated and smooth the liner
against the wall (see plan). Place the coping over the
liner and the stabilizer rails over the coping after pushing
it together about 15 cm. Replace all parts removed in
step 19 and repeat the same steps for all 3 top rails until
you assembled the entire pool.

SUPPLEMENTARY INSTRUCTIONS
FOR BUILDING A POOL IN THE
GROUND
To avoid that material rolls onto the site where the pool
is to be constructed, the location where the pool is to
be constructed must be in the most elevated part of the
garden. The surrounding landscape should be lower
than the pool. Attention, the water level of the pool
should also be above the groundwater level during the
winter (water level 15 cm below the inlet).
The specific installation such as seen in Figure 2 serves
only as a reference and is not representative for all pool
installations. The parts which may need special materi-
als are the lighting and chloride installations.
EXCAVATING
1. The circumference of the excavation is the same as
the size of the pool plus 60 cm around the whole
pool. Determine the size of the excavation pertaining
to the size of the pool and use for this the exten-
sive installation instruction delivered with the pool.
(Attention, the soil should be at least 15 cm white
sand or stabilized sand; on top of that we recommend
a layer of styrodur or a protective blanket.)
2. The depth of the excavation is dependent on the
height of the pool and desired terrace. Use the size
such as seen in Figure 1 to calculate how deep the
excavation should be.
3. After the pool is excavated, the frame and the wall
should be installed according to the installation ins-
truction delivered with the pool.
INSTALLATION OF SKIMMER AND INLET
The skimmer and the inlet have to be installed before
the pool is filled with water and before the pool is filled
up with stabilized sand. During the installation of the
internal lining and the skimmer, the lead through for the
skimmer may not be created yet. Install the inlet and
gasket. Remove the internal lining from the inlet opening
and install the valve delivered with the skimmer.
PLUMBER’S WORK
In order to prevent that the hoses move up and down,
you should connect the skimmer and the inlet with rigid
PVC to the filter (Figure 2). If you are using flexpipe, you
need to make sure that this pipe is not bent, before you
fill up the rest of the pool. Install the pump as closely as
possible to the pool in connection with the drawing in of
the pump. If this pump is a Doughboy Pool Powerpack,
then you should place it below the water level.
FILLING THE POOL
First fill the pool with water up to approximately 5 cm
away from the top edge. This procedure is absolutely
necessary to absorb the pressure performed on the wall
during the application of stabilized sand. Ff the pool
is not filled completely with water, this can cause pool
failure.
SHUTTERING
We recommend that you apply a shuttering around the
skimmer before the pool is filled up.A space around the
skimmer and any other accessories offer you the possi-

bility to have easy access for maintenance or repairs.
ATTENTION: If the filling up takes place immediately
around the skimmer, it shall be more difficult in the futu-
re to check the skimmer during leaks.
Doughboy is in no way liable for the expenses pertaining
to the finding and/or repairing of leaks, cutting, breaking
off and/or removing of stabilizing sand.
PREPARATION OF STABILIZER SAND
Mixing ratio 1 m3 fluvial sand with 125 kg concrete.
IMPORTANT WARNING:
Regardless the method used for the way the stabilized
sand is applied, you should pay close attention to the
wall of the pool during filling to be sure that the wall
does not collapse. If a dent occurs in the pool wall,
someone should enter the pool to push it back.
If this is not possible, you should lower the pressure to
the pool wall by removing the mixture
used to fill up the pool locally again so
that the dent can be removed. Then
carefully fill up the pool again. You
should at all times pay attention to the
pool wall until the pool is completely
filled up. To prevent rust on the pool
wall, the water streaming out of the pool
should immediately be removed from the
pool wall. For this you should let the top
layer run off at least 2 cm such as can
be seen from the illustration. After the
mixture has been applied completely,
you should lower the water level to the
top line of the skimmer opening and cut
away the liner in the skimmer opening.
IMPORTANT MESSAGE:
Piling up of loose material between the mixture and the
poor wall may push in the wall. If extra material is placed
between the mixture and the cover material to get this at
the correct height, you should only use a sturdy mortar.

INSTALLATION INSTRUCTIONS
PREPARATION OF THE POOL
The pool should be built up the correct way based
on the pool assembly and installation instructions.
Approximately 70 cm water should press against the
metal wall, so that there isn’t any elasticity anymore
against the liner, before the skimmer is installed.
ATTENTION: After the skimmer hole is cut open the liner
can no longer be moved.
Skimmer installation
1. Remove all parts from the carton box. Remove the
cover of the skimmer by sliding it to the front and
then lifting is; remove the skimmer basket.
2. Fasten the skimmer valve (7) to the skimmer (3)
by using three screws (8). Push the skimmer valve
into the skimmer so that the foam side is facing the
bottom.
3. Install the top skimmer gasket (9) into the square
opening of the metal wall; make sure that the gas-
ket is positioned properly in front of the holes. Then
fasten the bottom gasket (10) into the vacuum con-
nection. Place the skimmer plate on the inside of
the pool, and keep the skimmer on the outside of
the pool. First screw tight the top angles with two
self tapping screws. Press the self tapping screws
through the skimmer plate and press the liner into
the openings of the skimmer. Lightly tighten
the self
tapping screws.
Your standard skimmer facilitates the maintenance of
your pool. Leaves and floating refuse are taken out of
the water and enter into the skimmer basket. Clean the
basket regularly to continuously keep your pool clean
and hygienic. The numbers indicated between the brac-
kets refer to the numbers of the illustration (Fig 7).

Installation inlet fixture
1. Install the gasket of the inlet (17) into the wall ope-
ning. Insert the inlet fixture (18) through the liner and
the wall starting from the inside of the pool. Make a
small notch into the liner and press the inlet fixture
through.
2. Now screw the inlet (16) onto the inlet fixture; turn
it clockwise until the inlet end points towards the
bottom.
3. Install the eyeball inserted piece (20) into the eyeball
(21). Insert the eyeball with the inserted piece into the
inlet fixture, turn the closure (22) on top of that; make
sure that the eyeball location stands in the water run-
ning off direction of the skimmer opening
WARNING: Always keep the water level between the
water level signs on the skimmer plate.
After installation of the skimmer check if there are leaks
when the pool is filled. Continuous leaks can cause
damage to the pool wall, so that eventually there is pool
failure.
VACUUMING
Empty the skimmer basket before suctioning.
1. Switch off the pump. Assemble the vacuum nozzle,
handle and hose. A proper flexible hose provides the
best suction results. Attach the free end to the vacu-
um adaptor (13).
2. Switch on the pump. Keep the free end of the hose
against the outlet of the inlet fixture. Because of this
air shall pass through the hose. When bubbles no
longer exit from the vacuum nozzle, all air has been
removed (please refer to Figure 5/6).
4. Screw the rest of the self tapping screws through the
skimmer plate, liner, gaskets, wall and the correspon-
ding openings in the skimmer. Tighten all self tapping
screws manually; this to prevent damage to the skim-
mer plate. With a Stanley knife now cut away the liner
on the inside of the skimmer plate; do the same with
the vacuum inlet. (Fig 4)
ATTENTION: The gasket around the vacuum connection
(10) is necessary to ensure a watertight closure around
the vacuum connection during the suctioning off of
water. Attach the suction cover (12) and the attachment
of the suction cover (11) to the skimmer plate with a
screw (8).

3. Fold the cover of the vacuum opening (12) so that
it points towards the bottom. Insert the tapering end
of the vacuum adaptor with the hose attached into
the opening by making a turning movement (Fig. 7).
4. The cover (2) has two functions. In the normal
position is covers the top of the filter. During suc-
tion, this same cover becomes the closing plate for
suctioning; make sure that the pump is in the OFF
position. Remove the cover, turn it 90º and let it
drop to the inside and place it above the basket.
Make sure that there is no air under the cover.
Trapped air shall make the cover rise.
Warning: Never try to install the cover in a suctioning
position if the pump is switched on. The cover might
suddenly be pulled down due to the strong suction of the
pump. You may suffer personal injury to your hands or
fingers.
5. When the cover is in place, you can switch on the
pump and put into operation the suction of the pool
floor.
6. When you are finished suctioning, you have to switch
off the pump. Remove the vacuum hose with the
vacuum adaptor connected to it from the pool. Clean
the skimmer basket and your filter. Relocate the cover
to the original position on the top of the skimmer.
Switch on the pump to resume the normal operation
of the pump.

PREPARING FOR WINTER
When the swimming season is over, you have to follow
the instructions to get your pool ready for winter.
ATTENTION! Do not remove all the water from your
pool and also do not remove the liner. An empty pool can
namely cause pool failure.
Lower the water level
- Lower the water level in your pool so that it is approxi-
mately 6” (15 cm) below the inlet fixture; maintain this
water level by checking it regularly.
- If you have a skimmer, then absolutely do not let the
water freeze in the skimmer but rather drain this water.
Check all screws and connections
- Make sure that all installation connections and parts
are positioned correctly and that the pool wall is not
moved away from the bottom rails.
- Make also sure that all connections are water tight.
Check if there is rust
- Correct all damages or rust spots with a varnish stick.
Check the liner (interior tarpaulin)
- Make sure that the top of the liner is still overhanging
the pool wall attached to the plastic edge. Do not
remove the liner from your pool. Upon removal of the
liner of the pool the warrantee becomes void. Do not
pump dry all the water from the pool during the winter.
Leaks found
- Make sure that there aren’t any leaks in the liner.
Leaks during the winter can cause serious damages to
your pool.
Pool accessories
- Remove all pool accessories from the pool, including
the ladder. Leave the skimmer and inlet fixture in
place.
The filter
- Disconnect the filter from your pool and follow the filter
instructions for maintaining the filter during the winter.
Clean the pump and the filter for the winter (frost free).
Anti-freeze liquid
This liquid can be used without problems in combination
with chloride products. Upon finding algae present first
apply a ‘shock treatment.’ The liquid should be, dis-
solved in a pail of water, spread out equally across the
water surface. During the dosage the pump should be
in operation. The dosage is 0.5 litres per 10 m3, after
approximately four weeks 0.3 litres per 10 m3.
ATTENTION! Never mix the liquid with other pool che-
micals or chemicals and always add the product to
water, never the other way around.
If you do not adhere closely to the winter instructions,
the warrantee of your pool may become void. Thus care-
fully adhere to all instructions for maintaining your pool
during the winter.
