Placement / Installation
5.1
The pump is equipped with a motor protection type IP X4. When installed
outside we recommend providing some protection against the rain. This will
increase the longevity of your pump. When installed in a closed room, like for
example a cellar a drainage must be foreseen which is suitable for the
transported medium
1)
. The installation site of the pump must be dry. If the pump
is installed in a humid environment, effective ventilation and aeration must be
provided in order to prevent condensation. In case of extremely small, confined
installation places, the natural cooling of the air may be so insignificant that,
here too, a ventilation and aeration is necessary in order to avoid exceeding
environmental temperatures of 40°C.
Make sure by applying appropriate measures, that the environment will not be
impaired by any sound produced by the pump.
During installation, make sure that there is enough space available to permit
subsequent disassembly of the motor unit in the direction of the motor fan
(minimum 120 mm) and the strainer basket (143) towards above (minimum 140
mm), see directions in the dimensional drawing. Fastening the pump to the
foundation should be effected exclusively by means of bolts, threads (or
dowels) in order to avoid blocking the removal of the motor unit! Inlet- and
outlet-pipes must be mounted to the pump housing free of tension.
Caution:
Sealing of connecting parts only by means of Teflon tape!
5.2
Mechanical / Hydraulic:
The pump must be installed in a horizontal position in dry condition. It may be
installed either max. 5 m
below
(gravity feed) or
above
of the liquid level
1)
(suction mode). Thereby the geodetic head between liquid level and pump inlet
must not exceed 3 m. The suction lift may be significantly reduced by flow
resistance in the suction line, if the pipes are very long and/or insufficiently
dimensioned.
Only use sealing tape for connecting sleeves to pump!
Make sure that the suction line is not leaky, otherwise the pump will prime
insufficiently or not at all. The transparent lid must be screwed on tightly and
the suction/intake line should be as short as possible. This will reduce priming
time, which is dependent on the air volume in the intake line. If the intake line is
very long this may take up to 12 minutes. If possible the intake line to the pump
should be installed below the liquid level. Whenever the pump is installed
above the liquid level it is recommended to install a foot valve in the intake line.
Thus the suction pipe cannot drain itself when the pump has been turned off.
This keeps priming times short e.g. after having cleaned the strainer basket
(143).
