at anytime.

(Diagram 26)
Check the pool wall level by placing a length of timber beam or similar across the diameter of the pool wall and placing
the builders level on the top of the timber beam.
(See diagram 25)
lf the deviation is more than 2 cm (0.8")
(See diagram 26)
then the ground site must be levelled again. Check also if the pool wall is ovai and measure the
diameter across a few spots to make sure the differences of each diameter measured are within 2cm (0.8':)
lf the levels are not to specification then the area will have to be leveled again.
CAUTION! Try not to damage any of the components when dissembling the pool wall to correct the level of the ground.
Once the measurements and levels are correct and all nuts and bolts are tightened, then cover the exposed screw
heads with the Self Adhesive Tape (See
Diagram 27 and 28).
(Diagram 27)
(Diagram 28)
Piace the Self Adhesive Tape over the
exposed screw heads to seal them off.
MAKING A PROTECTIVE SAND CUSHION AT THE FOOT OF THE INNER POOL WALL
Pool Liner
Seam is
centred in the
middle of the
sand cave
PoolWall
To protect the liner against the rail and the pool wall, it is recommended to create a protective covering made of
fine brick sand at the foot of the pool wall.
(See diagram 29, 30).
The size should be 15cmH x 15cmW (6"H x 6" W)
so that it completely seals the rail but doesn't distort the pool liner.
FITTING THE PVC POOL LINEA
Fit the PVC liner on a warm and sunny day, preferably above 22
°
C(72
°
F). Unfold the PVC liner and put it in the
sun for 2 hours. This helps to soften the PVC. lf the temperature is below 16
°
C(60
°
F), the PVC liner will be hard
and rigid and quite difficult to handle Put the liner at the centre of the pool site inside the .pool wall Extend it
evenly until the seam line reaches the base of the pool where the protective sand cover is. Smooth out all the
wrinkles in the liner. Straighten the PVC liner and hold it perpendicular to the ground. Drape the pool liner over
the pool wall. There should be an overlap of 8cm (3"} of the pool wall height
(See diagram 31 and 32)
Hold the
overlap in piace with clothes pegs.
(Diagram 31)
(Diagram 32)
Check if the pool liner is placed evenly around the perimeter. Evenly fold the excessive length of the PVC if you
find it a bit loose. Check if the overlap is uniform. lf the pool liner is slightly short, then you will have to let it down
and vice versa. Fili the pool with 3 to 5cm (1 "-2") height of water to smooth out the liner against the pool wall.
Check to see if water is level, if not, something is wrong and you will have to dismantle the liner and pool wall to
access andlevel the ground area.
