9 Installation
9.1 Mounting/arrangement
The OffLine Separator OLS must be mounted in level and on a flat surface. No special
mounting is required. The standard pump is designed for ambient temperatures at 10 - 40°C
(50 - 104°F). In order to prevent the motor from overheating, adequate cooling air must be
provided.
Sufficient room to remove the filter element(s) must be left around and above the
housing.
9.2
Suction port connection
The suction port may be connected to a flexible hi-collapse hose, or to hard piping. If the
OffLine Separator OLS is connected to hard piping, precautions must be taken to ensure that
no stresses or vibrations are transmitted to the pump/filter housing. It may be necessary to
install flexible dampeners.
Constrictions in the connections and lines should be avoided to prevent compromising
suction output (
⇒
Cavitation danger).
The suction hose or pipe must be connected at the reservoir bottom (lowest point),
to secure efficient water removal from the main system.
9.3
Pressure port connection
The nominal size of the pressure hose should be equal to that of the filter housing port
whenever possible. If a smaller hose size is used, the pressure drop must nevertheless be
higher than 2 bar (29 psi) with a clean filter element
The nominal size of the connected hoses/piping, must be at least as large as the
inlet port sizes of the pump.
If large contaminant particles are present (
>
100 µm), an appropriate strainer must
be installed in the suction line to protect the pump.
If the OffLine Separator OLS is installed below the fluid level of the reservoir, shut
off valves must be installed in order to allow filter element replacement.
If a model without a pump-motor group is used, it is important to ensure that no
pressure pulsation is transmitted to the OffLine Separator OLS.
For back pressure above 1 bar (14.5 psi), a differential clogging indicator should
be installed.
