Degassing line
•
For gas-rich water from the system.
•
For degassed water into the system.
LIS
Level sensor
Make-up with water via a softening system.
•
Always integrate the device in the "V" main volume flow to ensure
degassing the system water. It is the system side in systems with central
return flow admixture or hydraulic switching points. The vessel of the heat
generator must be fitted with an individual protective device.
•
When using Reflex Fillsoft softening systems, always install the Fillset
Impulse.
–
The device controller evaluates the make-up quantities and signals a
required replacement of the softening cartridges.
Note!
The quality of the make-up water must comply with the applicable
standards such as VDI 2035.

Electrical connection
DANGER
Risk of serious injury or death due to electric shock.
If live parts are touched, there is risk of life-threatening injuries.
•
Ensure that the supply cable to the device is disconnected and secured
against being switched back on.
•
Ensure that the system is secured and cannot be reactivated by other
persons.
•
Ensure that installation work for the electric connection of the device is
carried out by an electrician, and in compliance with electrical locally
applicable electrical engineering regulations.
For the electrical connection, you must differentiate between a connection
component and an operating component.

The following descriptions apply to standard systems and are limited to the
necessary user-provided connections.
1.
Disconnect the system from the power source and secure it against
unintentional reactivation.
2.
Remove the covers.
DANGER Risk of serious injury or death due to electric shock. Some
parts of the device's circuit board may still be live with 230 V even after the
device has been physically isolated from the power supply by pulling out of
the mains plug. Before you remove the covers, completely isolate the
device controller from the power supply. Verify that the main circuit board
is voltage-free.
3.
Insert a suitable screwed cable gland for the cable bushing at the rear of
the connection component. M16 or M20, for example.
