Checking The System Pressure - ComfortZone RX35 User And Installation Manual

ComfortZone RX35/RX50/RX65

3.4 Checking the system pressure

The system pressure needs to be checked and the water system needs to be
replenished from time to time, because the air pockets that were initially in the
system are transported around and gradually emptied out. The first few days after
installation, the pressure should be checked daily.
• Adapt to the habit of always checking the pressure at least every time
the air filter is changed or cleaned and each time the radiators or floor
heating coils are aerated.

desired value.
