6. Installation
6.1 Installation requirements for Polydos systems
The safety of the overall system is only guaranteed, if the
installation requirements are strictly adhered to.
All installation work must only be carried out by qualified
and authorised persons.
Separate the system from the power supply before
working on the system components and lines.
Wear personal protective equipment.
Do not step on the system. The system is not designed to
carry the weight of a person.
The system is delivered completely assembled. On site only the
water, withdrawal equipment, drain and power supply must be
connected.
To ensure ergonomic refilling with dry material, provide a working
platform or use an automatic powder conveyor. A powder conveyor
can be purchased as an accessory from Grundfos.
Location
•
The installation location must be free of vibrations.
•
The installation location must be protected from rain, humidity,
condensation, direct sunlight and dust.
•
The installation location must be in a solid building.
•
The installation location must be sufficiently illuminated to
ensure safe handling of the system.
•
Observe the permissible ambient conditions.
Foundation
For the installation of the system, provide a solid concreted surface,
suitable for the weight and dimensions of the system.
Install the system on a horizontal foundation.
Maximum slope: 1:200
Make sure that the entire system is supported by the foundation.
Make sure that no foreign objects are between the foundation and
the system.
WARNING
Heavy system weight
Death or serious personal injury
‐
Observe the maximum floor load.
‐
The foundation must be based on a sufficiently bearing
ground.
Make sure all components are always easily accessible for
operation and maintenance.
Water supply
The quality and parameters of the water must comply with the
specifications in the technical data section. If the pressure is
insufficient, a booster pump is required.
The water supply connections must comply with the respective
international standards, e.g. double non-return valves on the inlet
connection.
Connective pipework
Make sure that all pipes and fittings of your installation are suitable
for drinking water.
Prior to installation, check all pipework and fittings between the
components for conformity with the local and international
legislation.
Make sure that the dimensions of all hydraulic lines are suitable for
the required flow rates.
