4.1 Separator commissioning

Before the separator is put into service please make sure that:
- The separator is completely clean, including inlet and outlet,
and that the interior of the chamber is free of dirt and debris.
- The cleaned separator is completely filled with clean cold
water up to the outlet.

4.2 Commissioning participants

The commissioning of the separator is usually handled by a tra-
desman although this can be handled by a KESSEL contractor
or KESSEL employee if desired.
1) The following people should be on hand during the commis-
sioning:
- Building contractor representative
- Plumber / tradesman who will be maintaining the separator
- Building maintenance personnel
- Disposal company who will be handling the disposal account
The first emptying (disposal) of the separator contents should
take place within 2 to 3 weeks from the day the separator was
placed into service.
Disposal intervals
According to DIN V 4040-2, it is advised that sludge and grease
separators should be fully emptied, cleaned and refilled with
cold fresh water at fourteen day intervals or at least on a month-
ly basis. In order for a grease separator to function as designed,
it is very important that the separator is emptied at regular in-
tervals as described above. Due to this, it is recommended that
a licensed disposal company is contracted to empty the sepa-
rator at regular intervals and during times when strong odours
will not present a problem. During disposal of DIN 4040 under-
ground grease separators, first the grease separation compart-
ment must be emptied and than the sludge compartment. This
prevents any flotation of integrated sludge compartment.
