Installing The Wall Skimmer To The External Sand Filter System - Swim & Fun Kreta XL Bedienungsanleitung

7. Installing the wall skimmer to the external sand filter
system
(Optional extras – not included with the pool)
Return inlet and in-wall skimmer
The Kreta garden pool is constructed so that it easily can be upgraded later to be used with an external sand filter sys-
tem. A sand filter system with a cleaning efficiency of at least 4 m3/h when operating will provide cleaner and clearer pool
water, minimise the need for chemicals and allow for the use of solar panels and make for an efficient vacuum cleaning of
the pool bottom.
Saw/cut carefully the round perforation (return pipe) out from the pool wall and the square perforation for the skimmer.
This cannot be done with a liner on the inside of the pool, so the liner must first be gently removed from the top rail in the
area – or alternatively it can be replaced with a new liner. When assembling the pool anew, holes are prepared in the pool
wall before the liner is installed in the pool.
The return pipe
Fill the pool with water to a level 5 cm of beneath the round perforation for
the return pipe.
Now cut a cross in the liner with a sharp utility knife – without cutting be-
yond the perforation of the hole.
Now install the return pipe inlet with 1 gasket from the pool side
outward. The resulting triangles of surplus liner must be cut clean-
ly and precisely along the exterior of the nozzle. Then install the
second gasket from the pool's outer side and tighten the large nut
outside the gasket. Use Teflon tape on the threads. The return inlet
must be tightly fastened, but do not over-tighten the nut (tighten
carefully).
If the return inlet is supplied with a loose seal for the installation of a filter hose, then Teflon tape must also be
used on the threads when the parts are assembled.
Once the return inlet is correctly installed, the skimmer can be installed.
The skimmer
Please note that the skimmer may have been supplied with either 2 single gaskets or one sandwich gasket.
Installation with two skimmer gaskets
Take the square inner frame of the skimmer kit (hard plastic) and one of the gaskets.
Insert a screw in each of the upper holes.
Place the skimmer frame on the inside of the pool and push the screws from the inside out through the two perforated
holes in the pool wall that fit. This will also penetrate the liner. Make sure beforehand that the skimmer frame and gasket
are positioned correctly so that all the holes are in alignment. On the other side of the pool wall, install the other gasket
and then fasten the screw into the screw holes of the skimmer housing.
Similarly, the other screws are installed from the inside of the side of the pool and out through the gaskets and into the
skimmer housing. All screw holes are thus aligned through the pool wall if installed correctly.
Make sure that the skimmer gaskets are uniformly installed along the perforation on both sides.
Tighten the screws in pairs diagonally and tighten evenly to ensure that they are watertight. Only use a manual screwdriv-
er and be careful not to over-tighten the threads (do not use an electric screwdriver!!).
Using a sharp knife, remove the liner around the edge inside the skimmer opening. Then carefully retighten the screws.
