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
supervision).
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.
Note: we always recommend concret-
ing the base with a reinforced base
plate 12 – 15 cm thick. The base plate
must be absolutely level.

2.4 The right surface
The place chosen for installation of the swim-
ming pool must be completely flat, so that any
little slopes must be evened out accordingly. 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 be approx. 1 m larger in diameter than the
pool itself.
Before you begin with the actual installation of
the pool, firstly the ground must be cleared of
any possible particles which could damage the
inner cover of the swimming pool. If necessary,
any remaining uneven patches can be smooth-
ed over with a fine layer of sand. Use a ground
protection tarpaulin or a layer of nonwoven
material to protect the swimming pool inner
cover. This kind of ground protection tarpaulin
should also be used on asphalt, concrete or
polystyrene paving. Asphalt, polystyrene and
fresh concrete are not compatible with PVC.
We always recommend the use of a ground
protection tarpaulin. This is the only way to
guarantee a longer service life for the pool
inner cover.
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:
• completely free-standing on the ground
• partly installed in the ground
• completely installed in the ground
English
44MTH SUNNY POOL round pool Installation recommendations and instructions for use

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.
2.8 Necessary structural work when
installing the swimming pool as
deep pool
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.
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
installed too quickly.
To achieve the best possible results when install-
ing the swimming pool, it is always advisable to
create a smooth and absolutely level concrete
slab underneath the entire swimming pool.
The backfilling material must not be vibrated
nor stamped in, because otherwise this will
damage the steel casing (denting on the
inside).

2.9 Additional water depth
For all swimming pools, you can increase the
depth in the middle of the pool by excavating
the ground in a cone shape. The highly elastic
inner cover of the pool is so stretchy that it can
adapt to this increased depth without any pro-
blems.
Please consult the following table to see which
additional depth is possible by excavating a
hollow of this kind, with reference to the in
dividual pool diameters.
Ø 4 m additional depth approx. 15 cm
Ø 5 m additional depth approx. 20 cm
Ø 6 m additional depth approx. 25 cm
Ø 7 m additional depth approx. 25 cm
Ø 8 m additional depth approx. 30 cm
Ø 9 m additional depth approx. 30 cm
Ø 10 m additional depth approx. 35 cm
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
control.
Risk of lacerations!

3.1 Marking the outline of the pool
Once you have prepared the ground, 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 cleared of any pointed objects. The tarpau-
lin is square and is cut to size after installing the
pool according to the steel casing.
3.3 Positioning the ground rail
Connect the individual segments of the ground
rail to make a circle, using the slot-in tubes. The
finished ground rail circle must be positioned pre-
cisely 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 seg-
ment of the ground rail using a hacksaw.
3.4 Installing the pool wall
Place a thick board in the middle of your ground
rail circle and place the rolled up sheet casing on
it (as shown in the picture).
Caution:
Caution: t the pr he prepar epared cut ed cutouts outs
f
for or 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.
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 corrosion inhibitor.
Note: if the prepared openings are not
required, seal them with the enclosed
foil.
3.5 Connecting the ends of the steel
casing with the slot-in profile
Once the complete steel casing (3) has been
inserted in the ground rail, connect the two
ends of the steel casing with the slot-in profile
(4) (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 down
over the rebate. It may help to move the ends
of the steel casing gently back and forth. The
profile must never be put on incorrectly or by
use of force. This damages the wall and redu-
ces 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 bet-
ween the floor/wall and the seam which
connects the bottom with the sides.
MTH SUNNY POOL round pool Installation recommendations and instructions for use

Note: the inner cover is produced to be under-
sized, 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 under-
sized, the piping has to be stretched when fit-
ting 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 (5) and fit it to the steel jacket (10) with
the piping (3). To keep the steel casing round
and secure the piping, place a handrail profile
(6) in position afterwards. Now continue in the
same way until all the inner cover has been fit-
ted. Any slanting folds which now appear on
the surface can be dealt with by removing the
handrail and fitting the inner cover again.
B) 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
because the wedge piping can be moved
horizontally.
Put the special profile (11) on the steel casing
(3) and fit the handrail (6) on top (see next
chapter). The steel casing now stands firmly so
that the following steps are much easier.
Now slide the wedge piping (12) of the pool
inner cover (5) into the chamber of the special
profile (11) 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
little folds with a brush or using your feet.
Now let water into the swimming pool, filling it
gradually.
Important! Please note:
Do not install the fitted components such
as skimmer or nozzles, which entail cut-
ting the corresponding openings in the
foil, until the water level comes up to just
below the level of the fitted parts.

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.
