Positioning/alignment
• A hook or eyelet with the corresponding bearing capacity is to be
installed vertically above the pump (for the total weight of the pump:
see catalogue/data sheet), to which hoisting gear or similar aids can
be attached when conducting maintenance or repair work on the
pump.
CAUTION! Risk of material damage!
Danger of damage due to incorrect handling.
• Only use lifting eyes on the motor for carrying the weight of the
motor and not for carrying the entire pump.
• Lift the pump using permitted load-bearing equipment (see chap-
ter 3 “Transport and interim storage” on page 5).
• Minimum distance between a wall and the fan guard of the motor:
30 cm.
• The suction and pressure flange are both marked with a cast arrow to
indicate the flow direction. The direction of flow must correspond to
the direction arrow on the flanges.
• Shut-off devices must be installed without fail in front of and behind
the pump in order to avoid the entire system being drained when the
pump is inspected or exchanged.
• Between the lower shut-off device and the pump, a drain cock must
be fitted for draining the pump during dismantling.
• When using the pump in air-conditioning or cooling systems, the
condensate which accumulates in the lantern can be discharged spe-
cifically via the existing holes. The lantern has an opening on the
underside which allows a drain pipe for condensation water to be con-
nected.
• The pipes and pump must be free of mechanical stress when installed.
• All installation positions except for "motor facing down" are allowed
(see Installation positions fig. 7).
• The air vent valve or a venting screw (fig. 1, Item 441h) must always
face upwards.
NOTE
The motor terminal box must not face downward or water may enter
into it. If necessary, the motor housing can be rotated after loosening
the fastening screws so that the terminal box is pointing upwards.
This also ensures that one of the venting screws (fig. 1, Item 441h) is
located at the highest possible point.
CAUTION! Risk of material damage!
Danger of damage due to incorrect handling.
• Do not damage the housing flat gasket.
NOTE
When pumping out of a tank, ensure that the liquid level is always
high enough above the suction port of the pump so that the pump
never runs dry. The minimum intake pressure must be observed.
NOTE
In the case of insulated systems, only the pump housing may be insu-
lated, not the lantern and motor.
• Two opposite holes (fig. 1, Item 365u) on the flange on the motor side
of the lantern make it possible (depending on the installation method)
to identify leakages in the mechanical seal. These holes must not be
blocked (remove plugs); provide a visible outlet for pipework.
