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!
When installing the on
-site safety valve, the operator must ensure that
there is no danger during blow-off.

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 Direc
tive 2014/68/EU are not supplied.
The operator is responsible for on
-site provision of water-side pressure
and temperature protection.
4 Description of the device
4.1 Description
The Variomat with touch control is a pump-controlled pressure maintaining,
make-up and degassing station for heating and cooling water systems. The
Variomat is essentially a controller with pumps and at least one expansion tank.
The expansion tank is fitted with a diaphragm to divide the tank into an air space
and a water space. preventing the ingress of atmospheric oxygen into the
expansion water.
The Variomat with touch control provides the following safety features:
• Optimisation of all pressure maintaining, degassing and make-up
processes.
– No direct intake of air thanks to a regulation of the pressure
maintenance with automatic make-up.
– No circulation issues caused by free bubbles in the circuit water.
– Reduced corrosion damage due to oxygen removal from fill and
make-up water.
