When connecting as a valve radiator:

LEFT	RIGHT

When connecting as a compact radiator:

• the valve insert has to be removed
• the plastic plugs have to be replaced with brass plugs.

* = a reduction in heat output will occur when combining low temperature heating with a high temperature difference between inlet and outlet.
