Reference; Maintenance - Greenheck IG Installation, Operation And Maintenance Manual

Motors
Motor maintenance is generally limited to cleaning
and lubrication (where applicable).
Cleaning should be limited to exterior surfaces only.
Removing dust and grease build-up on the motor
assures proper motor cooling.
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 build-up.
For large amounts of mineral build-up, clean or
replace the media and increase the water bleed-off or
flush rate.
The cooling media has a useful life of 3 to 5 years
depending on the water quality and the bleed-off or
flush rate.
IMPORTANT
When reinstalling the evaporative media, make sure
that it is installed correctly. Reference the drawing
shown below.
IMPORTANT
Replacement media should be from the same
manufacturer and be the same size as the original
media provided with the unit.

WARNING
Repair and replacement of the coil and the
connecting piping, valves, etc., should be performed
by a qualified individual.
Inspect the coil for signs of corrosion and/or leaks.
Repair any leaks as required.
Inspect the coil's surface for foreign material. If the
coil surface needs cleaning, clean the coil from the
leaving air-side so that foreign material will be washed
out of the coil rather than pushed farther in.
Inspect and clean the drain pan to prevent the growth
of algae and other organisms.
IMPORTANT
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.
