Insert the provided screws
and gently tighten them
alternately until the
extension neck appears to
be tightly against
the tank.
Backfilling
Pack material for backfilling against the tank
and at least 200 mm around it. Use sand or
gravel without any sharp stones that can
harm the tank. Be sure to fill in around the
lower edge so that the tank is well supported.
Do NOT use a vibratory plate
compactors when backfilling!
Emptying the tank
The tank is normally emptied
via the lid, but if the tank is to be
emptied via a separate emptying pipe,
a ventilation pipe must be fitted as
recommended by your local waste
removal provider. The ventilation pipe
should have a diameter 1,5x the diameter
of the emptying pipe. Without a
ventilation pipe, there is a risk
the tank will collapse inwards
upon emptying.
