‡
Installation location prepared for the installation of the system.
‡
Fixation material available: Anchor bolts in a suitable size for fixing the base frame
to the foundation.
1. Place the system at the installation location.
2. Drill holes through the base frame directly into the foundation. Borehole depth as
specified by the anchor bolt manufacturer.
3. Place the anchor bolts. Observe the manufacturer specifications.
4. When the anchor bolts have hardened in place, fix the base frame to the founda-
tion. Apply thread-locking fluid, e.g. Loctite, to screwed connections.
▶ System installed. Connect the pipes.
Alternatively, the system can also be sealed to the foundation. In this case, the base
frame is cast into the concrete foundation. The concrete foundation must weigh at
least 2.5 times as much as the system.
NOTICE
Connection to the public water supply network
When making the connection, observe the applicable regulations, guidelines and re-
quirements of the water suppliers.
In addition, take into account the special features of the location. E.G. If the suction
pressure is too high or too variable, install a pressure reducer.
To ensure that the system functions correctly, note the following points when con-
necting the pipework:
ƒ
All pipes must be self-supporting. The system must not bear the weight of the pipe.
ƒ
Connect all pipes to the system without mechanical tension. Use compensators to
connect the pipes!
ƒ
Lay the pipes so that air cushions do not form in the piping.
ƒ
Pipes must be tight.
ƒ
Prevent foreign, pathogenic substances from entering the piping (infiltration).
