Installing the expansion vessel
It is important when installing the expansion vessel to position it at the highest point in the circuit, preferably above the
heat pump. If there is a low ceiling making it impossible to fi t the tank above the pump, it can be positioned as illustrated
in the fi gure to the left. It is important to install the tank so that any air disappears upwards. Air will remain in the circuit if
the tank is fi tted incorrectly (see the fi gure to the right).

Example:
A 200 metres of hose type 40/35 with Brinol gives 200 x 0.29 litres Brinol/
metre = 58 litres of Brinol and 200 x 0.71 litres of water/ metre = 142 litres
