Checking the components
Components must be regularly checked to detect and repair faults at an early stage.
The regular controls include the following and other measures:
Visual control of the relevant device area for faults such as dirt, rust formation and damage.
8.4.1 Checking the heat exchanger
Check the heat exchanger form pollution at the air side, damage and corrosion.
Check connectors and screw connections.
Check the bleeding valve and the filling of the heat exchangers.
Check the anti-freeze concentration.
Check the function of the water drains and condensate drain.
8.4.2 Checking the condensate pump
Check the condensate pump for dirt, damage and appropriate function.
Check the condensate hose for dirt and damage.
Check the filling level sensor (DrainStick) for dirt, damage and appropriate function.
Check the condensate tray (hood) for dirt and damage.
8.4.3 Check the air guidance fins
Check the finds for dirt and damage.
Check the mechanical function of the fins.
8.4.4 Check the fan
The fan is maintenance free, due to its ballpoint bearing with life-long lubrication. An exchange of the bearings is
required at the end of the fat lifespan (for standard applications approx. 30 – 40.000 h).
Check the fans for dirt, damage and corrosion.
Check the fan attachment and fasten all attachment screws.
Check the function of the protective devices.
Take note of atypical bearing noises and vibration-free running.
Caution!
Humid atmosphere:
It is recommended to run the fans at least for two hours per month during prolonged standstill periods to ensure
that accumulated humidity is evaporated.
