3. Installation and Assembly
During ground-moving work, a PE-HD cable conduit DN 40 (outer dia. 50 mm) must be
laid. For this purpose, the tank must be scored using a 60 mm saw cap. The connection
distance between separator and switch unit must be kept as short as possible. Unne-

cessary changes of direction, particularly ones at angles greater than 45° must be avoi-
ded. The cable conduit must have a continuous gradient to the separator. Condensati-
on inside the cable conduit can be minimised through an airtight seal on the conduit on
the switch unit side. A cable pull wire can be included for any later cable installation. The
cable can be extended to a max. 60 m. When the cable is drawn into the conduit to the
switch unit, the cable screw connection at the conduit cover must be tightened firmly.
Then the union nut must be fixed on the end of the pipe.
