For vessels from 1000 mm Ø:
•
Connect the connection set (2) to the 1-inch barrel nipple of the
vessel flange.
•
Connect the connection sets (3) and (4) to the T-joint at the 1-
inch barrel nipple of the vessel flange.

Note!
The safety valve at the hydraulic system of the Variomat acts to protect
the vessel. It is not for protection of the connected system. The exhaust
line must be routed so that there is no danger during blowing off.

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.
•
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.

MAG Pressure expansion vessel
If required, install a diaphragm expansion vessel MAG ≥ 35 litres (Reflex N, for
example). It reduces the switching frequency and can be also used in the
individual protection of the heat generators. According to DIN / EN 12828, the
installation of valves between the device and the heat generator is required for
heating systems. Otherwise secure locking mechanisms must be fitted.
