For pump to operate with minimal vibrations and noise it should be installed:
- into the pipelines with axis (1-1) in horizontal position:
Fig. 3
- pipes should be without curves for at least 5-10 D (D = rated pipe diameter) from the flanges.
Pump must not be used in the safety pipelines.
Pump should not be used as a holder during welding!
Desired head orientation can be achieved by rotating pump head. Pump is mounted to hydraulic
casting with four screws. By unscrewing those head can be turned.
When reassembling, care should be taken to ensure seal fit. Failing that,
water could cause damage to pump internals.
Ambient should be dry and illuminated as appropriate. Pump seals prevent dust and particles
from entering as prescribed by IP class. Make sure that the distribution box cover is mounted
and that cable glands are sealing.
Pump will provide the longest lifetime with ambient at room temperature and moderate medium
temperature. Prolonged operation at elevated temperatures could increase wear. Aging is
accelerated by high power and high temperatures.
Pump head and drains between hydraulic castings and motor housing
should not be thermally insulated as insulation could interfere with cooling
and condense drainage.
Hot medium can cause burns! The motor can also reach temperatures that could
cause injury.

In order to use various web tools, pump should be connected to network or a personal computer
over Ethernet plug. User CAT-4 or better network cable connected to “PATCH” configuration if
plugged into a network or wired as “CROSSOVER” for connection to PC.
