IMPORTANT
Observe the following notes for installing the RWO
oil separator system SKIT S-DEB.
7.1
Pump
Note
In order not to overcharge the attached single
outlet pump (pos. 14), install the oil separator at a
low point of the engine room. The pump is
designed for a suction height of 6 - 7 m at medium
temperatures up to approx. 30°C and a pumping
head to 30 mWs
(3 bar).
Note
The pump is a displacement pump; it must not be
operated upstream of closed fittings.
Note
The rotational direction of the pump is
"CLOCKWISE" when viewed from the motor. If the
rotational direction is incorrect, there is an acute
danger that the pump will run dry!
The pump must never run dry, this must be avoided
at all costs!
You can avoid this danger by ensuring that the
rotational direction is correct. The control system will
only start the pump once the oil-separator housing is
filled with water.
Note
The oil-separation pump is designed to operate at a
maximum temperature of +45°C. At temperatures
higher than +45°C, excessive starting torque
occurs in the motor due to thermal expansion of
the materials which means that the motor is in
danger of being damaged beyond repair.
7.2
Suction line
The suction line from the bilge must be equipped with a
suitable dirt filter to protect oil separator and fittings from
rough contamination. We recommend a sieve basket with
a perforation of approx.
Æ
2 mm at sufficient free sieve
area. Upon request, we provide the appropriately
dimensioned sieve basket filter for every oil separator.
Please contact our sales department (

information).
Installed to the inlet of the oil separator is a non-return flap
(figure 4, pos. 1) (for SKIT/S-DEB 0,1-2,5 on the inside of
the container) which prevents a self-draining of the
