MNChinook 200M Instructions
Maintenance
Please follow the preventive maintenance program listed below. This will ensure that the turbine operates
reliably and safely with good efficiency.
Always shut down the turbine before attempting to carry out maintenance.
Post-Installation Checks (to be carried out one month after installation):
Check that the turbine mount pin is secure and has not worked loose. Adjust if required.
Ensure that the rotor hub is still securely fitted.
Ensure that the rotor blades rotate freely.
Monitor the output. Ensure that the turbine and charge controller are functioning correctly.
Annual Maintenance:
Inspect the tower / support structure.
Remove the turbine from its installation to a suitable workbench.
Remove the rotor blade assembly.
Inspect the edges of the rotor blades for damage such as dents or chips. The blades will become
unbalanced if they are damaged. This will cause vibration, noise and poor performance. If many
dents have occurred along the edges of the blades, a new set of rotor blades should be installed
(Contact MidNite Solar for replacements).
Inspect the roots of the blades (attachment tabs) for signs of stress cracking or fatigue. A new set of
rotor blades should be installed if any cracks of fractures have occurred.
Remove any build-up dirt and debris from the rotor blades using mild detergent in warm water.
Check the blade hub for excessive play.
Check and rebalance the rotor blades as required.
Check that all electrical connections are sound and free from corrosion.
Generally ensure that the turbine is in good working condition and is safe for continued use.
After Five years of normal operation:
We recommend that the rotor bearing and rotor blades should be replaced after five years of continuous
operation. This will ensure that the tur
bine’s performance and safety are not compromised.
Other Considerations:
o
The equipment used in the charging system (batteries, charge controller, PV panels, etc) should be
maintained according to the instructions provided by the equipment manufacturer.
o
Where lead acid batteries are used, it is especially important that they are maintained carefully. Failure
to do so will result in the batteries being rendered useless within a short period of time.
