CAUTION
Risk of burns on hot surfaces
Hot surfaces in heating systems can cause burns to the skin.
•
Wear protective gloves.
•
Please place appropriate warning signs in the vicinity of the device.
CAUTION
Risk of injury due to pressurised liquid
If installation, removal or maintenance work is not carried out correctly, there is
a risk of burns and other injuries at the connection points, if pressurised hot
water or hot steam suddenly escapes.
•
Ensure proper installation, removal or maintenance work.
•
Ensure that the system is de-pressurised before performing installation,
removal or maintenance work at the connection points.
Note!
Equipment parts with a safety function in respect of water-side pressure
limiting according to the Pressure Equipment Directive 2014/68/EU and
temperature limiting according to the Pressure Equipment Directive
2014/68/EU are not supplied.
The operator is responsible for on-site provision of water-side pressure
and temperature protection.
Note!
When installing the on-site safety valve, the operator must ensure that
there is no danger during blow-off.

Expansion vessel
A butyl bladder divides the interior of the vessel into an air space and a water
space. This prevents the ingress of atmospheric oxygen into the expansion water.
The primary vessel is connected to the air side control unit and connected
hydraulically to the system circuit. Pressure relief is provided on the air side by the
vessel's "SV" safety valve.
Control unit
The control unit comprises a compressor and the "Reflex Control Smart" controller.
Via the primary vessel, the pressure is measured using the "PIS" pressure sensor
and the water level using the "LIS" weight measuring cell and the values are then
displayed on the control unit and via the app, 9 "Controller", 27.
