• 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.
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 (Fig. 16).
• The pump is only to be lifted with approved load-bearing equip-
ment.
• Minimum axial distance between a wall and the fan cover of the
motor: Free dismantling dimension of at least 200 mm + diameter of
the fan cover.
• Shut-off devices must always be installed in front of and behind the
pump in order to avoid having to drain the complete system when the
pump is inspected or replaced.
• The pipes and pump must be free of mechanical stress when installed.
The pipes must be fastened in such a way that the pump does not
bear the weight of the pipes.
• The direction of flow must correspond to the direction arrow on the
pump housing flange.
1 • The bleed valve (Fig. 17, Item 1) must always face upwards.
• All installation positions except for "motor facing down" are allowed.
• The electronic module must not face downwards. If required, the
motor can be turned after loosening the hexagon head bolts.
NOTE
After loosening the hexagon head bolts, the differential pressure sen-
sor is attached to the pressure measuring lines only. When turning the
motor housing, make sure that the pressure measuring lines are not
bent or kinked.
NOTE
When pumping out of a tank, ensure that the fluid 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 maintained.
• 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. A drain pipe can be connected at this
opening. Small amounts of fluid leakage can be also drained off.
NOTE
In the case of insulated systems, only the pump housing may be insu-
lated, not the lantern or motor.
