PUMP INSTALLATION
4.1
INSTALLATION INTO PIPE LINES
The arrows on the hydraulic casing and thermal insulation indicate the direction of the medium flow. For the
pump to operate with minimal vibrations and noise it should be installed into pipe lines with its 1-1 axis in
horizontal position, as showed in . Pipes should be without curves for at least 5-10 D (D = rated pipe diameter)
from the first curve.
Desired head orientation can be achieved by rotating the pump head (allowed positions shown in figure figure
1. Pump head is mounted on the hydraulic casting with four screws. The pump head can be turned by unscrewing
the four screws (figure 3). When reassembling care should be taken to ensure seal fit. Failing to ensure seal fit
could cause leaking of water into and damage to internal pump parts.
Pump ambient should be dry and well lit. The pump is sealed from dust and water according to its
ip class.
Misconnection or overload could cause pump shutdown or even permanent damage.
The pump doesn't have a ventilation screw. It is ventilated together with the system. Air in
the pump can cause noise, which will disappear after a short working period.
Pump must not be used in the safety pipelines,
Glands must be tightly screwed,
When used in climate systems remove thermal insulation from pump,
The pump should not be used as a handle for welding the pipe system, since it can be
damaged,
If the gasket between the electro-motor part of the pump and the console is not correctly
installed, the pump will not be watertight and there is danger of damage to the pump,
There are openings for condensate drain on the housing of the electric motor, these must
remain free (must not be thermally insulated), as this may interfere with the cooling of the
engine or the discharge of condensed water, figure 2,
Medium temperature must be higher or the same as ambient temperature, so that the
condensate doesn’t gather on pump surfaces.
Operation outside recommended conditions may shorten pump lifetime and could void the
warranty.
Operation at edge conditions can shorten pump lifespan.
