Installation and operating instructions Wilo-Stratos GIGA
• The pump should only be installed following completion of all welding
and soldering work and, if necessary flushing of the pipe system. Dirt
can cause pump failure.
• The pumps must be protected from the weather and installed in a
frost/dust-free, well-ventilated environment which is not potentially
explosive. The pump must not be installed outdoors.
• Install the pump in a place that is easy to access so that subsequent
inspections, maintenance (e.g. mechanical seal) or replacement is
easily possible. Air flow to the electronic module's heat sink must not
be restricted.
• A hook or a lug with sufficient load-bearing capacity must be installed
vertically over the pump (total weight of the pump: see catalogue/
data sheet). This is to allow hoisting gear or similar aids to be attached
to the pump during maintenance or repair work.
DANGER! Danger of death!
The pump itself and the parts of pump can be extremely heavy.
Falling parts pose a risk of cuts, crush injuries, bruises or impacts,
which may lead to death.
• Always use suitable lifting equipment and secure parts against fall-
ing.
• Never stand underneath a suspended load.
CAUTION! Danger of property damage!
Danger of damage due to incorrect handling.
• If the transport eyes have been moved from the motor flange and
installed at the motor housing, then they are only approved for
carrying or transporting the motor impeller unit (Fig. 24) and not
for transport of the whole pump and not for separation of the
motor impeller unit from the pump housing (pay attention to the
previous dismantling and subsequent installation of the spacer).
• Transport eyes that have been installed at the motor housing are not
approved for the transport of the whole pump and not for separating
or pulling out of the motor impeller unit from the pump housing.
• Only lift the pump with approved load-bearing equipment (e.g.
block and tackle, crane, etc.; see chapter 3 "Transport and interim
storage" on page 5).
• When installing the pump, an axial minimum wall/roof clearance of
the motor's fan cover of 16 in (400 mm) is to be maintained.
NOTE:
Shut-off devices shall be installed in front of and behind the pump
in all cases, in order to avoid having to drain the entire system when
checking or replacing the pump.
