the pool water and the electric motor. Because of the pump's close coupled de-
sign, a minimum of space is required. The pumps are driven by A.C. and tree-
phase motors. Integrated in the pump housing is a strainer basket (143), which
keeps coarse impurities from the pump's interior.

Placement / Installation
5.1
CAUTION
The pump is equipped with a motor protection type IP X4. In case the pump is
installed outside, we recommend nevertheless to see for a simple rain protecti-
on. This will increase the durability of your pump. If the pump is installed in a
humid space, effective ventilation and aeration must be provided for, in order to
prevent condensation. In case of very small installation spaces, the natural coo-
ling of the air may be so insignificant that, also there, ventilation and aeration is
necessary in order not to exceed the environmental temperature 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, mini-
mum 120 mm, and of the strainer basket (143) towards above, minimum 230
mm, see directions in the dimensional drawing. Fastening the pump to the foun-
dation 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: The ABS-gluings, glue socket (721), require a longer hardening pe-
riod. Starting the pump is only possible after 12 hours. When using the internal
thread, the connecting parts must be sealed with Teflon tape only.
5.2
CAUTION
Mechanical / Hydraulic
The pump must be installed in a horizontal position and in dry condition. It may
be installed either max. 3 m below water level (gravity feed) or above water
level (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 di-
mensioned. Make sure that the suction line is not leaky, otherwise the
pump will prime insufficiently or not at all. The transparent lid must be scre-
wed 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 water level. Whenever the
pump is installed above the water level it is recommended to install a foot valve
in the intake line. Thus the intake line cannot drain itself while the machine is
shut down. This keeps priming times short e.g. after cleaning of the strainer bas-
ket (143).
