with a leakage spray at the gap between the pump housing and the
lantern as well as their screwed connections.
• In the event of continual leakage, use a new O-ring, if need be.
CAUTION! Risk of property damage!
Incorrect handling can result in property damage.
• When turning the components, make sure that the pressure meas-
uring lines are not bent or kinked.
• When reinstalling the differential pressure sensor, bend the pressure
measuring lines evenly and as little as possible to put them into the
required position or into a suitable position. When doing this, do not
deform the areas at the clamp boltings.
NOTICE:
When turning the differential pressure sensor, make sure not to mix
up the pressure and suction sides on the differential pressure sensor.
For additional information about the differential pressure sensor, see
chapter 7.3 "Electrical connection" on page 84.
• Install only after completion of all welding and soldering work and
after the pipe system has been flushed, if required. Dirt can cause the
pump to fail.
• 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. The air access to the heat sink of the electronic mod-
ule must not be restricted.
• 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.
DANGER! Risk of fatal injury!
The pump itself and pump parts 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 falling.
• Never stand underneath a suspended load.
CAUTION! Risk of property damage!
Risk 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 (Fig. 20).
• Only lift the pump with approved lifting gear (e.g. block and tackle,
crane, etc.; see chapter 3 "Transport and interim storage" on
page 67).
• When installing the pump, an axial minimum wall/roof clearance of
the motor's fan cover of 200 mm + diameter of the fan cover is to be
maintained.
NOTICE:
Shut-off devices shall be installed upstream and downstream from
the pump in all cases, in order to avoid having to drain the entire sys-
tem when checking or renewing the pump. A non-return valve shall
be installed on the pressure side of each pump.
