4.3. Storage
Newly delivered products are prepared for up to 1 year of
storage. If the product is being placed in interim storage, it
must be thoroughly cleaned before being stored!
The following must be observed for storage:
•
Place product securely on a fixed base and secure
against tipping over.
•
In addition, ensure that the equipment is stored in dry
areas.
•
Products with vacuum and/or pressure connections
must have these tightly closed to prevent contami-
nation.
•
During extended storage the shaft must be protected
against moisture, sunlight, heat and frost.
If you observe these regulations, your product can be sto-
red for a longer period of time. However, note that the
elastomer parts and coatings are subject to natural em-
brittlement.
4.4. Materials returned
Products that are returned to the factory must be clean
and correctly packaged. "Clean" means that the product
has been cleaned of contaminations and that it has been
contaminated in the event of use with mediums that are
hazardous to health. The packaging must protect the pro-
duct from damage. Please contact the manufacturer befo-
re returning the product.
5. Installation and initial operation
5.1 General
To avoid damage to the lifting unit during installation and
during operation, the following points must be observed:
•
The installation work must be performed by qualified
personnel in compliance with safety regulations.
•
The lifting unit must be inspected for possible dama-
ge prior to installation.
•
Protect the pump from frost.
•
The power lines of the pump must be laid in such a
way, that a safe operation and easy assembly/disas-
sembly is ensured.
•
A dry run is strictly prohibited. We recommend level
control for this.
5.2 Installation
It is up to the operator to prevent consequential da-
mages, for example by flooding of rooms during dis-
turbances at the pump, by means of appropriate
measures (e.g. installation of an alarm system, a re-
serve pump or similar).
The lifting unit must be installed so that the lid can be
opened. Be sure to allow sufficient space between
the vertical/horizontal inlets and existing walls
20 | ENGLISH
•
The system must be installed so that the operating
and serviceable items are easily accessible. Be sure
to allow sufficient free space (approx. 50 cm) on all
sides.
•
Install a shut-off valve in the inlet line in order to faci-
litate the work steps during maintenance or possible
dismantling of the system. A ball valve is installed in
the pressure line.
•
To avoid deposits in the horizontal pressure line, the
line and the system must be designed for a minimum
flow rate of 0.7 m/s and at least 1.0 m/s for vertical
lines.
•
The inlet through the horizontal pipe can take place
via DN 40 drain pipe. In addition, vertical connection
options are available via inlet pipes DN 40 and DN
100. For the desired connection, the corresponding
opening on the respective inlet connection of the tank
must be cut and connected to the pipe using the ela-
stic transition piece supplied. The internal diameter of
the inlet line and inlet pipe must be coordinated.
•
The discharge line should have a diameter of at least
DN50 and should not be laid in tight bends. The line
must be laid above the backflow level, i.e. it must be
laid in a continuous rise above this level, and must
then feed directly to the manifold in a loop.
•
Freezing of the discharge line must be excluded. It is
advisable to sufficiently insulate the entire discharge
line all the way to the backflow level.
•
Cut open the vertical vent pipes and install a DN 70
vent line on the storage tank using the supplied ela-
stic transition piece. The vent line must be installed
without clogs and secured against buckling or ben-
ding. If a vent pipe is not possible or not available,
a suitable aerator including activated charcoal filter
should be fitted directly to the vent connection.
5.3. Commissioning
This chapter contains all important instructions for opera-
ting personnel for safe commissioning and operation of
the system.
The following points must be taken into account to avoid
personal and material damage when
troubleshooting machinery failures:
The commissioning of the machinery must only be
carried out by qualified and trained personnel in com-
pliance with the safety regulations.
•
All personnel that is working on the machinery must
have received, read and understood the operating in-
structions.
•
This machinery is only suitable for the use under the
indicated operating conditions
Never let the pump run dry for longer periods of time
(risk of overheating).
Before commissioning the system, existing pipe val-
ves or gate valves must be opened.
