English INSTALLATION
5.2. Installation types
•
Aerator field is anchored securely to the bottom
of the basin.
5.3. Operating space
• The operating space must be clean, free of coarse
solids, dry, frost-free and, if necessary, decon-
taminated.
• During any work in pump chambers, a second
person must be present for safety reasons.
• Take the necessary countermeasures if there is
a risk of toxic or suffocating gases collecting!
• The set-down location must have a solid bear-
ing surface and be designed appropriately and
dimensioned large enough, so that the entire
load can be unloaded and stored according to
specifications in the section “Transportation and
storage”. Furthermore, the access road to the
set-down location must be accessible for a lorry.
• Provision of electricity, water and compressed air
for the installation.
•
Ensure that lifting equipment can be fitted with
-
out any trouble, since this is required for assembly
and dismantling of a complete aerator field. It
must be possible to reach the aerator field safely
in its operating and storage locations using the
lifting equipment.
•
To transport the aerator field, the load bearing
equipment must be attached to the pipes using
approved lifting gear. Ensure that the payload will
not slip during transport.
• Structural components and foundations must be
of sufficient stability in order to allow the product
to be fixed securely and functionally. The opera
-
tor or the supplier is responsible for provision of
the foundations and their suitability in terms of
dimensions, stability and strength!
5.3.1. Material to be provided by the customer
• The inlet pipe for air supply
The aerator field is connected via the shut-off
ball cock to the inlet pipe. The position of the
inlet pipe must remain unchanged after the order,
or it can lead to problems during installation.
In addition, the inlet pipe must be self-support-
ing. The weight of the inlet pipe must not be
transferred to the aerator field.
• Fan or compressor
The fan or the compressor must be able to pro-
vide sufficient power to introduce the required
amount of air into the aerator field.
5.4. Work steps
Installation takes place in the following steps:
1. Checking the operating space
2. Unpacking and checking components
3. Marking the complete installation plan in the
operating space
4. Installing the pipework
5. Installing the panel diffuser
• Directly on the basin bottom
• Over threaded rods for subsequent levelling
5.4.1.
Checking the operating space
Before starting the installation, check the operat-
ing space to see if it is prepared accordingly for
the installation:
•
The configuration of the system as well as the
installation and drilling plans are in line with the
current conditions.
• The operating space is cleaned and the com-
ponents (air supply, fan) provided on-site are
prepared/installed accordingly, and a function test
(fan) was performed.
• The inlet pipe for the air supply was purged to
remove potential contaminants.
• Plastic (PE, PUR) becomes brittle in cooler tem-
peratures. Therefore the ambient temperature
during installation should be above +15 °C.
Installations at an ambient temperature
below +5 °C are strictly prohibited!
5.4.2. Unpacking and checking components
The individual components must be unpacked in a
clean, dry and frost-free place near the installa-
tion site.
Open the packaging carefully, so you do not hurt
yourself or damage the components.
Check all components for damage. Faulty parts
must not be installed. In this case, contact Wilo
customer service.

5.4.3. Marking the complete installation plan in the
operating space
Transfer the complete installation plan on the
wall and floor of the operating space. Accurately
draw in all pipe clamps, tapping sleeves and the
position of the aerators.
Make sure that the marking is water-proof!
5.4.4. Installing the pipework
Installation of the pipework begins at the hando-
ver point of the inlet pipe provided by the cus-
tomer. During installation it must be made clear
whether the PE pipe is used as reel or rod product:
•
Reel products: The PE pipe can be directly con
-
nected and fixed to the basin wall and/or the
basin floor with pipe clamps. Here there must
be enough space so that during installation
above the corner a radius of at least 1 m can
be adhered to. If this radius is not possible, 90°
installation bends must be used.
•
Rod products: The PE pipe must be shortened
to the required length each time. For the con-
nection of the individual pipes 90° mounting
brackets and/or in case of lengths above 6 m
