The air vented from the solar fluid is collected in the top of the air vent
and can be evacuated via the vent plug.
1. Switch on the circulating pump. The air bubbles are directed
2. Vent several times with the vent plug 2 until the heat transporting
3. Stop the circulating pump.
4. Open the air vent and then close it again.
Repeat the operation several times; alternate operation of the pump
assists degassing.

towards the venting points.
fluid comes out without any bubbles or particles.
CAUTION
Depending on the fluid temperature and system pressure,
when the degassing screw is opened, the fluid may spurt
out with some force. If the water temperature is high, be
careful: RISK OF SCALDING / BURNS.
CAUTION
Bleeding must be continued until pressure variations can
no longer be detected at the pressure gauge, or when
starting or stopping the pump. If the pressure drops
continuously, repair the leaks and top up with heat
transporting fluid.
The pressure gauge needle may move owing to the
modulation of the circulation pump.
CAUTION
After a few days of operation at high working temperature,
bleeding should be repeated. This bleeding is necessary
because small air bubbles form in the propylene glycol at
high working temperatures.
CAUTION
For systems installed in the winter, it is advisable to bleed
them again in the summer.
