Connection Requirements - ACO Lipujet-P-OAP Instrucciones De Empleo

Secure against moving forces of free-standing systems in the event of flooding or of
■
back water from the drainage channel. A downstream pumping system is to be used for
drainage if the at-rest water level of the grease separator is below the back water level.
The fastening rings (13) installed on the floor are to be used to anchor the grease
■
separator and protect it from moving forces. The protruding flooring can be anchored
with several mounting plates for grease separators made of HDPE.

3.1.2 Connection Requirements

Intake pipe requirements:
Waste water is to be fed into the grease separator in a free fall of at least 2 % (1:50).
■
If this is not possible, the use of ACO feed hoppers with displacement pumps is recom-
mended.
The transition from downpipes to horizontal pipes is to be executed with two 45° pipe
■
bends and a transition piece of at least 250 mm in length (pipe bends of the same quality
with a corresponding radius). This is to be followed by a length of flow damping pipe
in the direction of flow, the length of which must correspond to at least ten times the
nominal width in mm of the separator intake pipe.
Intake pipes must be made of materials resistant to fatty acids (e.g. KML, PP, PE).
■
Vent pipe requirements:
Lay the vent pipe until it extends over the roof. Connecting pipes longer than 5 m are to
■
be separately vented.
If the intake pipe above the grease separator does not have a connecting pipe with a
■
separate vent over a distance of more than 10 m, this pipe is to be provided with an
additional ventilation pipe as close as possible to the grease separator.
The connecting piece (7) on the grease separator can be used instead of an additional
■
connection in the intake pipe close to the grease separator.
No ventilating valves are permitted in sections threatened by back water and for venti-
■
lating the grease separator.
Vent pipes must be made of materials resistant to fatty acids (e.g. KML, PP, PE).
■
Disposal pipe requirements:
Disposal pipes used as pressure or suction pipes must be executed in not less than a
■
nominal pressure rating of PN 6. Use high-tensile connections for individual pipes and
fittings.
Use corrosion-resistant materials (e.g. plastic pipes made of PE or PP) for disposal
■
pipes.
