MAG
Expansion vessel
If required, install a bladder 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 bladder
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.
Installation detail of the "DC" degassing line
Connect the "DC" degassing lines as shown below.
•
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 line
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
Fitting the level sensor
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 sensor uses a pressure load cell. This pressure pick-up is to be
installed after the primary tank has been placed at its final position, see
chapter 6.3.4 "Tank installation" on page 9 . Comply with the following
instructions:
•
Remove the transport securing device (squared timber) at the vessel base
of the primary tank.
•
Replace this transport securing device with the pressure load cell.
–
In the case of a tank volume of 1000 l (Ø 1000 mm) or more, use the
supplied screws to attach the pressure load cell at the vessel base of
the primary tank.
•
Avoid shock-type loading of the pressure load cell by, for example,
subsequent alignment of the vessel.
•
Use flexible hoses to connect the primary tank and the first secondary tank.
–
Use only the supplied connection sets, see chapter 6.3.4 "Tank
installation" on page 9 .
•
Perform a null balancing of the filling level when the primary tank is
aligned and fully emptied, see chapter 9.3.1 "Customer menu" on page 18 .

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 system is voltage-free before installing the device.
•
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 engineering
regulations.
