Tank installation
ATTENTION
Damage due to improper installation
Additional device stresses may arise due to the connection of pipes or system
equipment.
•
Ensure that pipes are connected from the device to the system without
them being stressed or strained.
•
If necessary, provide support structures for the pipes or equipment.
ATTENTION
Device damage resulting from dry running of the pump
If the pump is incorrectly connected, there is a risk of dry-running.
•
Ensure that the connections for the overflow collector and the pump are
not interchanged.
•
Ensure correct connection of the pump to the primary tank.
(All data in mm)
Comply with the following notes regarding the installation of the primary tank
and the secondary tanks.
•
All flange openings at the tanks are viewing and maintenance openings.
Install the primary tank and the secondary tanks, if provided, with
sufficient spaces at the sides and the top.
•
Install the tanks on a level surface.
•
Ensure rectangular and free-standing position of the tanks.
•
If you use secondary tanks in addition to the primary tank, ensure that all
tanks are of the same type and dimensions.
•
Do not attach the tanks to the flooring to ensure the functioning of the
"LIS" level sensor.
•
Install the control unit on the same level as the tanks.

•
Align the primary tank.
–
The distance of the primary tank to the control unit must match the
length of the connection set.
•
Connect the connection set (2) and (3) with the screw fittings and gaskets
to the connections at the lower tank flange of the primary tank.
–
Ensure that you connect the connection set for the overflow collector
to the connection (2) below the label (1).
•
Interchanging the connections may cause the pump to run dry.
–
For tanks up to 740 mm Ø:
•
Connect the connection set (2) and (3) to the two free 1-inch
barrel nipples at the tank flange.
•
Connect the connection set (4) of the secondary tank to the T-
joint at the outlet of the tank flange.
–
For tanks from 1000 mm Ø:
•
Connect the connection set (2) to the 1-inch barrel nipple of
the tank flange.
•
Connect the connection sets (3) and (4) to the T-joint at the 1-inch barrel
nipple of the tank flange.
Note!
If necessary, install the supplied connection set (4) at the optional
secondary tank. Connect the connection set (4) with a user-supplied
flexible pipeline to the primary tank.
6.3.4.1
Connection to the facility system
CAUTION
Hot water vapour can cause burns to skin and eyes.
Hot steam can escape from the safety valve. The hot steam will cause scalding of
the skin and eyes.
•
Ensure that the blow-off line of the safety valve is routed so that injuries
are not possible.
ATTENTION
Damage due to improper installation
Additional device stresses may arise due to the connection of pipes or system
equipment.
•
Ensure that pipes are connected from the device to the system without
them being stressed or strained.
•
If necessary, provide support structures for the pipes or equipment.
6.3.4.2
Degassing line to the system
The device requires two "DC" degassing lines to the system. One degassing line is
intended for gas-rich water from the system, and the other one serves to return
the degassed water to the system. Shut-off devices for both degassing lines have
been pre-installed at the device. The connections of the degassing lines must be
made within the main flow volume of the facility system.
