DRAINING THE MODULE
The water is drained from the module by opening the air drain valve
(19)
, located inside the module
on the lower left hand side of the heat exchanger. Connect a flexible tube to this valve and run it to a
drain. After draining the module, close the valve again and remove the flexible tube.
During the draining process, it is recommended to switch off the module and
disconnect it from the mains.
