NOTICE
To facilitate service and maintenance, it is recommended to install shut-off valves as
close as possible to the inlet and outlet of the unit.
7.2.4 To connect the brine level vessel
The brine level vessel (delivered as accessory) must be installed on the brine side of
the heat pump system. A safety valve is included with the vessel. The vessel serves
as a visual indicator of the brine level of the system. Air trapped in the system is
collected by the vessel, causing the level of brine in the vessel to decrease.
1 Install the brine level vessel as the highest point in the brine circuit on the
entering brine piping.
2 Mount the included safety valve on top of the vessel.
3 Install a shut-off valve (field supplied) below the vessel.
