8.4 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.
