5. Installation/Assembly
5.1
The installation site of the pump must be dry. If the pump is installed in a humid
space, effective ventilation and aeration must be provided for in order to pre-
vent condensation from forming.
In case of very small installation spaces, the natural cooling of the air may be
so insignificant that, also there, ventilation and aeration is mandatory in order
not to exceed the environmental temperature of 40°C. Enough reserve space
must be provided for to allow removal and replacement of the motor unit in the
direction of the motor fan (120 mm respectively), or of the strainer basket to-
wards above (min. 140 mm). (See directions in the dimensional drawing).
5.2
Mechanical/Hydraulic Aspects :
The pump must be installed level and in a dry place. It may be installed either
below (Gravity feed, max. 5 m), or above the water level (in suction mode). In
that case, the head between water level and pump (geodetic head) may not ex-
ceed 3 m. The suction lift may be significantly reduced by flow resistance in the
suction line. (Excessively long or insufficiently dimensioned pipes).
Use only
sealing tape for connecting sleeves to pumps ! If the suction line is leaky or
the lid has not been screwed on tightly, the pump will prime insufficiently or not
at all. The intake line should be kept as short as possible. This will reduce prim-
ing time which is a function of the air volume inside the intake line. With very
long intake lines, priming will take up to 12 minutes. If possible, the intake line
to the pump should be installed
below the water level. Wherever the pump
must be installed above the water level, the installation of a footvalve is recom-
mended. Thus the intake line cannot drain when the pump is not working. This
keeps priming time short (e.g. after cleaning the strainer basket). Also, the
transparent lid must be attached tightly and securely.
5.3
Electrical Installation to be performed by qualified personnel only !
Make sure that the electrical installation is equipped with an earth leakage
switch which permits separation from the power supply by a gap of at least
3 mm for each contact. The pump has been designed in accordance with pro-
tection system I. The environmental temperature must never exceed 40°C. For
