Motors
Motor maintenance is generally limited to cleaning and lubrication (where applicable).
Cleaning should be limited to exterior surfaces only. Removing dust and grease
Motors supplied with grease fittings should be greased in accordance with the manufacturer’s recommendations.
important
Do not allow water or solvents to enter the motor or bearings. Motors and bearings should never be sprayed with steam, water or solvents.
important
Greasing motors is only intended when fittings are provided. Many motors are permanently lubricated, requiring no additional lubrication.
Filters
Filter maintenance is generally limited to cleaning and replacement.
If aluminum mesh filters are installed, they can be washed in warm soapy water.
An adhesive spray can be added to aluminum mesh filters to increase their efficiency.
If disposable filters are installed, they can be checked by holding up to a light source. If light cannot pass through the filter, it should be replaced.
IMPORTANT
When reinstalling filters, be sure to install them with the airflow in the correct direction. An airflow direction arrow is located on the side of the filters.
IMPORTANT
Replacement filters should be from the same manufacturer and the same size as the original filters provided with the unit.
Chilled Water Coils
Test the circulating fluid for sediment, corrosive products and biological contaminants. Make the necessary corrective measures.
Maintain adequate fluid velocities and proper filtering of the fluid.
If automatic air vents are not utilized, periodic venting of the coil is recommended to remove accumulated air.
Evaporative Coolers
The media should be periodically brushed lightly with a soft bristle brush in an up and down motion while flushing with water. This aids in reducing the amount of mineral

Be sure to read and follow the manufacturer’s recommendations before using any cleaning fluid.
caution
Caution should be used to avoid injury when venting the coil. High pressure and/or high temperature fluids can cause serious injuries.
