Installation
Damage due to improper installation
Additional device stresses may arise due to the connection of pipes or system
equipment.
• Pipelines must be connected so there are no residual forces and torques
and must be routed so they are free from vibrations.
• If necessary, provide support structures for the pipelines or equipment.
• If you have any questions, please contact Reflex After Sales & Service.
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 volume flow of the system.

MAG Pressure expansion vessel
If required, install an expansion vessel (MAG) ≥ 140 litres (Reflex N, for example).
It reduces the switching frequency and can be also used in the individual
protection of the heat generators. The p0 setting of the expansion vessel (MAG)
should be identical to the p0 setting of the controller. According to DIN / EN 12828,
the installation of shut-off devices between the appliance and the heat generator is
required for heating systems. Otherwise secure locking mechanisms must be
fitted.
Connection detail of the "DC" degassing line
Connect the "DC" degassing lines as shown below.
36 — English
• Ensure that particulate dirt cannot enter and thus create an overload of the
"ST" dirt trap.
• Connect the degassing line for gas-rich water upstream of the degassing line
for degassed water in system direction of flow.
• The water temperature must be in the range 0 °C – 70 °C. The return side
should be preferred for heating systems. This ensures the permissible
temperature range for degassing.
6.3.5 Fitting the thermal insulation
Install the optional thermal insulation (2) around the primary tank (1) and close the
insulation with the zip fastener.
 Note!
For heating systems, insulate the primary tank and the "EC" expansion
lines against heat loss.
– Thermal insulation is not required for either the primary tank top or
the secondary tank.
 Note!
On-site, install thermal insulation when condensate forms.
6.3.6 Installation of the weight measuring cell
ATTENTION
Damage to the pressure load cell due to unprofessional installation
Incorrect installation may result in damage to the "LIS" level sensor,
malfunctioning and incorrect measurements from the pressure load cell.
• Comply with the instructions regarding the installation of the pressure
load cell.
The "LIS" level measurement uses a pressure load cell. This pressure load cell is
to be installed after the primary vessel has been placed at its final position,
 6.3.4 "Tank installation",  35. Comply with the following instructions:
• Remove the transport safety device (squared timber) at the mounting foot of
the primary vessel.
• Replace this transport safety device with the pressure load cell.
– The pressure load cell can optionally be fastened to the mounting foot
of the primary vessel using the supplied screws. However, fastening is
not necessary.
• Avoid shock-type loading of the pressure load cell by, for example,
subsequent alignment of the vessel.
• Use flexible hoses to connect the primary vessel and the first secondary
vessel.
