In the case that no grease flows out into the collection barrel,
the heating duration must be extended, until the hardened
grease turns liquid. Depending on the room temperature and
the amount of grease this heating could me more than two
hours. On the control unit display the heating mode is dis-
played. The internal temperature sensor regulates the hea-
ting until the programmed heating time has elapsed. The start
and stop of the heating dome occurs automatically.
In the case that no grease drains into the grease collection
barrel:
a) The amount of water in the separator is not sufficient to
create enough pressure to push out the grease. In this
case a drainage fixture connected to the grease separa-
tor (kitchen sink for example) should be run to allow more
water into the separator
b) If there is still hardened grease in the separator. The dis-
posal intervals should be shortened (draining of grease
and sludge should take place more frequently)
Step 3: Sludge disposal
Slowly open the valve (4a, page 14) of the sludge trap (C).
Observe the sludge draining through the transparent hose
(11b, page 14) into the sludge collection barrel. Close the
sludge drainage valve as soon as the amount of draining
sludge decreases noticeably or if the sludge barrel is full (S).
Note:
Make sure to check the following when the disposal
process has ended:
- All valves are in the basic setting (closed) – except for the
rinsing valve (1c, page 14) which should remain in the open
position.
- The heating (B) is off
- The pump (P) is off
Step 4: Collection barrel exchange
Note:
close valves and follow all safety instructions!
Prepare an empty collection barrel and remove its cover. Di-
sconnect the drainage pipe and ventilation pipe from the
collection barrel and unclip the quick release clamp. Slowly
remove the cover from the full tank (any remaining fluid in the
drainage will have enough room in the collection tank) and
place onto the empty barrel and connect.
Place the closed cover onto the full collection barrel and se-
cure properly. Mark the barrel to identify the contents (‘Grea-
se’ or ‘Sludge’). We recommend changing the barrels at a
later to date to allow them to cool and settle – preferably when
the next disposal takes place. During this time the grease can
settle to the top of the collection barrel and any water can
settle to the bottom. This will aide in the reduction of odours
when exchanging barrels.
Note:
- In the case that the collection barrels are so full that sludge
or grease backs up into the transparent hoses then it is im-
portant to change the barrel´s immediately to prevent any
blockage from building up in the hoses.
- Store all full barrels in a cool and frost free area.
- Collection barrels which are full should be taken off site as
soon as possible. If stored too long, and depending on the
temperature of the storage room, the contents of the bar-
rels can begin to decompose causing gas build up which
can result in gases / odours escaping from the barrels.
- In the case that a disposal company handles the removal of
the barrels, make sure that any replacement barrels sup-
plied to you by the disposal company are the same size as
the original barrels and have an original KESSEL cover.
Tips on reducing odour build up
1. When exchanging barrels to it cleanly and quickly.
2. Make sure that the barrels covers are properly secured.
3. Any spilled wastewater should be quickly cleaned up.
4. Any filled or partially filled storage barrels (depending on
room temperature) should be removed from site at a ma-
ximum within 4 weeks. It is recommended that the barrels
are stored in a very cool (frost free) area.
The decomposition process in the collection barrels results
in gas build up inside the barrels which can cause them to
bulge and release bad smelling odours. By continuous odour
problems please see Section ‘Malfunctions and Remedial
Measures’.
