Casella CEL Multimet - Manual (Page 14)

4. MAINTENANCE AND SERVICE
4.1 Routine Maintenance
The Multimet is designed to provide many years of trouble free operation,
however, as with all mechanical systems, some regular maintenance and
inspection may be required.
Periodically check the system for the following:
Signs of physical damage Inspect the anemometer cups,
direction vane,
cabling,
connectors and mounting components
for signs of damage or deterioration.
Replace any damaged components as
necessary.
Ease of rotation Ensure both the wind vane and cups are
free to rotate.
Excessive friction may indicate that
bearing replacement is required.
4.1.1 The Multimet
The display should require no maintenance other than periodic cleaning using
a soft cloth. DO NOT USE solvents or other cleaning products.
4.1.2 The Wind Speed and Direction Sensors
Cleaning the sensors and cross arm may be carried out using a soft damp
cloth. DO NOT USE solvents or other cleaning products.
Apart from cleaning, no other regular maintenance is required, as the
number of moving parts is so few and the bearings on the main spindle are
sealed against dust etc.
If the average wind speed is low and weather conditions moderate,
it is estimated that six years life can be expected from the bearings. With a
higher than average wind velocity and a bad exposure, for example near the
sea, then 4 to 5 years might be expected. At the end of this time it is
recommended that the bearings be replaced with new ones. Consult Casella
CEL Service Department.
