Deaerator - MAXA i-290 0106 Installer Manual

5.10.7 Deaerator
The unit is equipped with a high-efficiency deaerator that continuously captures and eliminates
air and any refrigerant gas that may accumulate within the hydraulic circuit, avoiding undesirable
effects such as premature corrosion and wear, reduced efficiency and exchange yield, as well as
possible contamination of the water by R290 gas. The exhaust capacity is very high, with automatic
gas expulsion down to micro-bubble level.
The deaerator is made of brass, a strong and durable material.
The deaerator must always be installed in a vertical position and in an outdoor ambient. It must
be mounted immediately downstream of the unit on the hydraulic outlet pipe: in the event of gas
expulsion, this will be within the danger zone, without causing any fire risk. The installation of the
deaerator is compulsory to ensure the safety of people, animals and property, and necessary to
maintain the warranty. Always follow the instructions in this manual: incorrect installation or in-
stallation in areas different from that prescribed (indoors or outdoors), as well as failure to install,
commissioning and proper maintenance of the device must be considered as a possible cause of fire.
The mixture of water and glycol can greatly reduce the deaerator's ability to remove dissolved gas-
es: it is recommended to limit the glycol concentration to a maximum of 10%. Use products with a
low tendency to foam, which could completely nullify the degassing effect and damage the system.
The installation of the deaerator must be carried out by qualified personnel according to national regulations and local
requirements.
Ensure that the device connection fittings are hydraulically tight.
Do not exert mechanical stress on the connection threads during installation, which could damage the component.
Do not exceed the maximum amount of glycol indicated in the manual, as this may reduce the deaerator's ability to remove
gas, causing damage to the component
Access to the moving parts that control the vent is obtained, after tapping the system,
by removing the top cover.
After tapping the system, unscrew the part of the body containing the vent valve, to
which the separator element is attached, for cleaning. This part is not removable.
