FLOW SWITCH
The flow switch monitors if there is a liquid flow in the system.
When there is no sufficient liquid flow present as a result of an
error, for example when the liquid is frozen or air in the pump-
housing, the system will shut down. This error can be caused by a
lack of liquid in one of the reservoirs. This error can be solved by
refilling the reservoirs. This can be done by removing the plug on
top of the reservoirs and refilling the reservoirs with cooling fluid
(
see picture:
Refilling the reservoirs
).
AIR BUFFER
The reservoirs contain an integrated air buffer that levels out
pressure valuations. The air buffer is hidden under the plugs on top
of the reservoirs. Therefore these plugs may never be removed. For
a more flexible system concerning the positioning of the ECO-
ClimaTEC in the vehicle, it is also possible to fill the reservoir
completely, including the air buffer. Instead of the air buffer an
overpressure valve is mandatory in this situation.
