3.1 General
Preparations
1.Where and how are the suction lines, power supply for motor (5 x 1,5 mm2) and
grounding (min. 6 mm2) routed into the house.
2.Selection of suitable above- or below-ground cable routing and wall penetration
incl. watertightness must be taken into account.
•he pipes must be installed above ground in a protective pipe of at least Ø
DN160
•or at least ØDN200 must be routed underground.
3.Use only bends with 45° to allow easy retraction of the hoses.
For the Flexilo Outdoor outdoor tank, a paved subsoil and a gravel subsoil with a min-
imum height of 10 cm are required. Additional concrete slabs facilitate the installation
of the tank and additionally improve the stability.
NOTICE
Accumulated water must be avoided at all costs!
If underground installation of the suction hoses is selected, the protective tube must
be at least 5 cm above the inner floor edge of the external tank. The protective tube
should protrude to the left or right in the motor area of the tank. The base plate must
be suciently recessed in this area
NOTICE
Depending on local conditions, the distance from the house wall should be 10-50 cm.
▶Observe the country-specific regulations.
CAUTION
The tank must be protected from the weather during installation!
Complete resistance to weathering exists only when the film is mounted on the tank
completely closed.
▶Only assemble the tank in dry weather conditions.
Required tools
•Horizontal bar 2 m
•Measuring tape
•Pencil
•Jigsaw
•Drill, bit inserts, screws
•Wood drill Ø4 mm
•Hole saws approx. Ø51 mm ±1 mm
and approx. Ø30 mm ±1 mm

3.2 Preparatory work
Secure location choice
•Level surface, free from backwater
•Safety against slipping, accessibility for filling process
•Excavate the soil at least 10 cm, compact and gravel.
•Recommendation:
•Align 7 pieces of concrete slabs (40x40x4 cm) in the scale.
Above-ground or underground laying of the suction hoses
NOTICE
Line length must not exceed 20 m per hose.
Variant 1 underground cable routing
•In the case of underground piping, install a protective pipe with at least ØDN200
and bends with max. 45°.
•Install the wall duct by means of a pipe duct and a lining pipe (to be provided in
the concrete formwork).
•Check with the builder or an expert to determine the appropriate penetration for
a brick wall.
•The pipe should protrude so far from the ground that the end of the pipe is at
least 5 cm above the top of the ground.
NOTICE
Until the tank is fully built up, the pipe end must remain closed.

Installation manual

Variant 2 above ground line routing
•For above-ground piping, install a protective pipe with at least ØDN160 and
bends with max. 45°.
•Install the wall duct by means of a pipe duct and a lining pipe (to be provided in
the concrete formwork).
•Check with the builder or an expert to determine the appropriate penetration for
a brick wall.
•Attach the DN160 wall bracket (accessory) on the outside and lay the protective
pipe with 45° bends up to the outer tank.
•At the tank there is an insertion nozzle on which the hoses as well as the adapter
for the protective tube can be mounted.
Grounding/potential equalization
•Grounding of the filling nozzle:
Observe the country-specific regulations.
