Oval pool for do-it-yourself
installation
The oval pool must be installed at least 2/3 in
the ground.
Note: the two support walls are not
included in the scope of supply and
must be produced by the customer.
1. General safety instructions
Please do not let children play at
or in the pool without supervision.
Explain to them about the dan-
gers (keep the swimming pool
covered for example with a safety
cover if it is not under super-
vision).
Always have a shower before get-
ting into the pool. People suffering
from circulatory disorders should
get into the pool slowly.
Caution: danger when falling in.
Low water depth. Do not jump
into the pool.
Caution: make sure that only a
qualified electrician connects up
any electrical appliances such as
filter systems, underwater spot-
lights, etc. according to VDE
0100 Part 702.
2. Before installation:
Read through the installation
recommendations and instructions
for use thoroughly. Only correct
installation prevents the warranty
from becoming null and void.
Before starting installation, check that the swim-
ming pool is complete and in perfect condition.
Report any transport damage.

2.2 Safety instructions steel casing
Caution: before unpacking the
steel casing, please read the dan-
ger label on the steel plate and
comply with the instructions in the
chapter on installing the pool.
2.3 Location
The ideal location is sunny and protected from
the wind.
2.4 The right surface
The ground under the swimming pool should be
so-called natural ground. It must not consist of
heaped up ground. Any heaped up ground
must be compacted in such a way that it can
take the necessary swimming pool load of
1200 kp/m2for a pool depth of 1.20 m or
1500 kp/m2for a depth of 1.50 m.
The ground excavated for the swimming pool
must correspond to the dimensioned drawing
plus working space of about 50 cm all round.
That means that the ground excavated should
be 1 m longer and 1 m wider than the length
and width of the finished pool.
Use a ground protection tarpaulin to protect the
PVC swimming pool inner cover, because fresh
concrete is not compatible with PVC (this also
applies to asphalt and polystyrene).
2.5 Temperature and wind
The inner cover foil of the swimming pool is
made of soft PVC (thermoplastic material). In
view of the properties of this material, the best
conditions for installing the swimming pool pre-
vail when the outside temperature is between
15°C and 25°C.
Note:
If the temperature is too low, the foil is
hard and inelastic, and therefore too
small.
If the temperature is too high, the foil is
soft and elastic, and therefore too large.
When fitting the inner cover, please note that
bright sunshine can cause excessive stretching.
You cannot install the swimming pool when
there is a strong wind, because the wind can
easily tip the steel casing over. This can cause
damage.
2.6 Installation of the
swimming pool
You can install your swimming pool in various
different ways:
• 2/3 in the ground
• completely installed in the ground
2.7 Installing the swimming pool on a
slope
As already mentioned, the swimming pool must
not be installed on heaped up ground which
has not been suitably compacted in advance.
That means that the installation surface for the
complete swimming pool must be in the natural
ground of the slope, as shown in the picture.
The slope down to the pool must be contained
by a small wall or corresponding embankment.
The slope must certainly not rest on the wall of
the swimming pool.

2.9 Necessary structural work
For the oval pool, the customer is responsible
for excavating the corresponding building pit,
producing the reinforced base plate and the
two support walls. Please consult a building
contractor.
Once the pool has been installed, the curved
ends of the pool must be backfilled correctly
with lean concrete. The backfilling material must

not be vibrated nor stamped in, because other-
wise this will damage the steel casing (denting
on the inside). Sand, grit or other free-flowing
material must never be used for backfilling the
swimming pool.
Instead of a backfilling, the support wall can be
continued round the curved ends.

Excavation
Draw the outline of your swimming pool on the
ground using a cord compass. Please refer to
the dimensions table (page 5) for the necessary
dimensions. To leave sufficient working space of
about 0.5 m all round, the pit should be exca-
vated about 1 m longer and wider than the
actual pool.
Base plate
The reinforced base plate (2) should be 12 –
15 cm thick and must be perfectly level and
smooth.
Support walls
The two straight walls of the swimming pool are
formed by a support wall (3).
Please consult the dimensions table (page 5)
for the dimensions of the support wall (M).
The support walls are produced by brickwork
on the reinforced concrete base plate (2) and
connected to the base plate with reinforcing
iron rods.
We recommend using 24 cm hollow block
bricks. It goes without saying that the individual
layers of brickwork have to be offset and also
reinforced with structural steel. The hollow block
bricks are then filled with lean concrete.
The brickwork wall should be built up to the
height of the pool casing.
Fastening the steel casing
To improve the appearance of the pool, we
recommend that the steel casing (5) is fastened
to the support wall (3). The fastening angles
(11) can be used for this purpose: they are bed-
ded in mortar in the top joint of the support
wall.

3. Installing the swimming pool
At least 2 persons are necessary to install the
swimming pool.
The metal edges of the steel casing are
very sharp! The steel casing has been roll-
ed up and is under considerable tension.
Always wear safety gloves throughout the
entire unpacking and installation
procedure.
Warning! Risk of injury!
While cutting through the strap retainers wound
round the roll of steel sheeting, it is very impor-
tant for a second person to hold the upper end
of the roll together with both hands wearing
safety gloves for protection. When cutting
through the strap retainers of the roll which has
been stood on end, always work from bottom
to top, i.e. cut through the strap retainer nearest
to the ground first.
Otherwise there is a risk of the tension being
released upwards in an uncontrolled one-sided
manner with the steel roll unwinding out of con-
trol.
Risk of lacerations!
3.1 Marking the outline of the pool
Once the base plate and support walls have
been finished, draw the outline of the swimming
pool on the ground using a cord compass.
3.2 Positioning the tarpaulin
Position the tarpaulin on the flat ground which
has been carefully cleaned and cleared of any
pointed objects. The tarpaulin is rectangular
and is cut to size after installing the pool accor-
ding to the steel casing.
R

Installation recommendations and instructions for use GALAXY POOL oval pool

Cutouts:
Carefully make the prepared openings for the
fitted skimmer and nozzle, filing and carefully
deburring the edges.
Use the double gasket for the skimmer. If this is
not provided, treat the cut edges with a corro-
sion inhibitor.
Note: if the prepared openings are not
required, seal them with the enclosed
foil.
3.3 Positioning the ground rail
Connect the individual segments of the ground
rail to make an oval, using the slot-in tubes. The
finished ground rail must be positioned precise-
ly on the line you drew on the ground for the
swimming pool circumference. The ground rail
can be cut exactly to size after installing the
wall of the swimming pool by sawing off the
last segment of the ground rail using a hack-
saw.
3.4 Installing the pool wall
Place a thick board in the middle of your
ground rail and place the rolled up sheet
casing on it (as shown in the picture).
CCaauuttiioonn::
the prepared cutouts for skimmer
and intake nozzle must be at the
top!
Now unroll the steel wall slowly,
inserting the steel casing into the
ground rail as it is released from
the roll.
You must wear safety gloves!
Please make sure that the white-coated side of
the swimming pool wall points to the outside
(not for Metal-tec).
Note: put a few segments of the hand-
rail in position to hold the steel casing
provisionally during the installation pro-
cess. Once the steel casing has been
installed and inserted in the ground rail,
compensate for any possible differ-
ences in length between the ground rail
and the steel casing at the ground rail.
Important:
The skimmer cutout must be positioned in the
right place (see optimum water feed system:
longitudinal flow or circular flow). Consult your
swimming pool expert first.

3.5 Connecting the ends of the steel
casing with the slot-in profile
Once the complete steel casing (5) has been
inserted in the ground rail, connect the two
ends of the steel casing with the slot-in profile
(6) (see drawing). Please ensure that the rebate
of the steel casing fits properly in the slot-in pro-
file. It must be possible to slide the profile (6)
down over the rebate. It may help to move the
ends of the steel casing gently back and forth.
The slot-in profile (6) must never be put on
incorrectly or by use of force. This damages the
wall and reduces the stability of the swimming
pool.
3.6 Fitting the inner cover foil
Climb into the swimming pool using a ladder
(wear rubber boots or go bare foot) and place
the inner cover foil on the middle of the swim-
ming pool floor.
Now start to spread the foil out from the middle
to the outside so that there is even spacing be-
tween the floor/wall and the seam which
connects the bottom with the sides.
NNoottee::the inner cover is produced to be
undersized, i.e. it is slightly smaller than
the sheet casing. This is the only way to
avoid possible folds in the foil, but they
cannot be prevented completely.
However, this does not constitute any
quality impairment and has no effect on
the service life of the foil. Because the
foil is undersized, the piping has to be
stretched when fitting the foil; more
when the weather is cold, and less
when it is warm.
A. Fitting the inner cover foil with
conventional piping.
Evenly lift the wall section of the pool inner
cover (7) and fit it to the steel casing (5) with
the piping (11). To keep the steel casing (5)
round and secure the piping (11), place a
handrail profile (8) in position afterwards. Now
continue in the same way until all the inner
cover (7) has been fitted. Any slanting folds
which now appear on the surface can be dealt

with by removing the handrail and fitting the
inner cover again.
B.1. Fitting the inner cover foil with wedge
piping and special profile.
Advantages:
•Easier procedure: steel casing is immediately
stable.
•Edge stones can be placed directly on the
handrail.
•Slanting folds can be dealt with easily be-
cause the wedge piping can be moved
horizontally.
Put the special profile (12) on the steel casing
(5) and fit the handrail (8) on top (see next
chapter). The steel casing now stands firmly so
that the following steps are much easier.
Now slide the wedge piping (13) of the pool
inner cover (7) into the chamber of the special
profile (12) until the entire inner cover has been
fitted in position.

3.7 Fitting the handrail
Press the first segment onto the edge of the
swimming pool over the fitting profile or special
profile. Then fit the second segment of handrail
exactly onto the first segment using the connec-
tion tube. Continue until the entire handrail has
been completed. Adjust the precise length using
the provided partial piece of handrail or by
sawing the handrail with a hacksaw.
Once all handrail segments have been fitted on
the edge of the swimming pool, knock the indi-
vidual handrail pieces onto the swimming pool
wall using your hand or a rubber mallet. If gaps
have appeared between the segments during
the installation process, please loosen the hand-
rail again and push the segments closer
together.

3.8 Filling the swimming pool
Check that the inner cover foil fits properly.
Remove any possible folds on the floor of the
swimming pool. Now let some water into the
swimming pool. Once the water is approx. 2
cm deep, you can smooth out any remaining lit-
tle folds with a brush or using your feet.
Now let water into the swimming pool, filling it
gradually.
3.9 Backfilling the pool wall
Caution: sand, grit or other free-
flowing material must never be
used for backfilling the swimming
pool installed fully in the ground.
We always recommend a layer of
lean concrete approx. 20 cm
thick as backfilling.
3.10 Equipotential bonding
DIN 57100 (Part 702) and VDE (Part 702)
stipulate equipotential bonding for swimming
pools. To this end, the provided parts can be
used, for example, according to the following
drawing.
Protect connection parts from corrosion
(varnish) when exposed to moisture.
5 Steel casing
14 Equipotential bonding
15 To the earthing
16 Equipotential bonding cable
17 Nut, lock washer, plain washer, nut,
lock washer
18 Screw
Please note that the backfilling must be installed
gradually as the pool is filled with water. This is
particularly important when using lean concrete
for backfilling. Concrete is far heavier than
water, so that there is a risk of the concrete
backfilling causing dents in the pool if it is instal-
led too quickly. The backfilling material must
not be vibrated nor stamped in, because other-
wise this will damage the steel casing (denting
on the inside).
Important! Please note:
Do not install the fitted components
such as skimmer or nozzles, which en-
tail cutting the corresponding openings
in the foil, until the water level comes
up to just below the level of the fitted
parts.
Installation recommendations and instructions for use GALAXY POOL oval pool

4. Instructions
4.1 Important when emptying the pool
If the swimming pool is to be emp-
tied and cleaned, it should be
refilled again preferably on the
same day. Otherwise there is a
risk particularly during bad
weather (rain) of the backfilling
shifting and deforming the steel
casing.
When using a pump to empty the
swimming pool, make sure that
the water is drained at a good
distance and certainly not allow-
ed to seep into the ground in the
immediate vicinity of the swim-
ming pool.
4.2 Repairs
Damage to the pool inner cover can be dealt
with easily using a repair kit. Please comply
with the instructions enclosed with the repair kit.
If the paintwork on the swimming pool steel
casing is damaged, please repair the damage
using commercially available paint suitable for
outdoor conditions.
4.3 Winter storage
Swimming pools which have been partly or
completely installed in the ground can survive
the winter full of water. All parts of the swim-
ming pool are elastic enough to withstand the
weather conditions.
Please note:
Before the frost period starts,
remove all fitted parts such as
skimmers and filter systems. If the
skimmers or nozzles have been
permanently installed, lower the
water level accordingly. Please
also remove the swimming pool
ladder before the frost period
starts.
It is advisable to protect the swim-
ming pool with a tarpaulin cover.
To avoid unnecessary cleaning work in the
spring, we recommend the use of a winter pro-
tection agent. This winter protection agent is
simply added to the swimming pool water and
prevents limescale and dirt from settling on the
pool inner lining; it also prevents algae forma-
tion in the water. This makes the next spring
cleaning much easier in your swimming pool.
