Disposal

The latest time for emptying a separator
is when:
1. 80 % of the maximum oil storage has
been reached
2. and/or 50 % of the maximum sludge
trap volume has been reached.
The type plate shows the relevant thick-
nesses of each layer (the type plate is
located inside the separator).

General inspection procedure

Prior to commissioning and thereafter at
regular intervals of maximum five years,
a properly qualified technician*) must
inspect the separator to ensure that it is
in good condition and operating properly
– this general inspection must be carried
out after first complete emptying and
cleaning the separator. An integral part
of every general inspection is a tightness

Entering the separator

Warning
All of the relevant accident prevention re-
gulations must be strictly observed when
entering a separator.
The separator can be entered via the
maintenance shaft which is usually loca-
ted above the float cage. Entering the
following models (Oleopator-C-OST und
Oleosmart-C-OST) is possible via openings
above the float cage. In these cases,
carry out the following steps to ensure
optimal accessibility:

1. Remove the coalescence unit (if ins-
talled)
2. Remove the float switch
3. Pull the float cage from the holder and
remove it
The separator can now be entered.
Once all of the work has been carried out,
the next steps ensure that the original
condition of the separator is reinstated:
1. Place the float cage back in the holder
(taking care to properly align the pins
in the cage)

Caution
In accordance with DIN 1999-101, if bio-
diesel enters the separator, the light liquid
separated out should be removed from
the surface of the water after one year.
The light liquid separated out must be re-
moved immediately after accidental spills.
Warning
The tightness test is carried out by fill-
ing the separator with water and this can
generate upward forces on the cone or
the cover plate. It is therefore necessary
to place a test load on the top section of
the shaft to stop it from moving upwards.
The test loads are specified for each
type of ACO separator in the installation
instructions.

2. Replace the float switch after the sepa-
rator has been filled
3. Install the coalescence unit (if installed)
The float cage does not need to be remo-
ved in any of the other models because
the separator can be entered by a third
maintenance shaft.
