MAINTENANCE INFORMATION

Part I

There are no lubrication points on the chiller. All motors have permanent
lubrication in the bearings.

The water that is used in the chilled water circuit has no special requirements,
except that deionized water cannot be used. The water should be clean and some
type of water conditioner can be used. Nothing should be used in the chilled water
circuit that could damage the all copper Heat Exchanger. THIS INCLUDES THE
USE OF DEIONIZED WATER.

The air-cooled condenser should be cleaned on a regular basis, depending on the
environment the chiller is installed in.

The water level should be maintained as close to the level as marked on the
water sight glass. You can damage the refrigeration system by the water being
at a low level, it will only effect the efficiency of the unit.

5. Caution: The compressor receivers and water pump could be hot enough to

injure one touching these components.

The dial thermometer is reading the temperature of the discharge chilled water.

7. Please

note: This is a hermetically sealed compressor. There are no necessary

maintenance requirements. Please read the service bulletins before making any
repairs.

SPECIAL NOTICE

To clean the condenser it is necessary to remove the access panel, you
remove this panel by lifting up on the panel and pulling it out at the bottom.
When this panel is removed you can brush away all the foreign matter. You
must always put this access panel back in place or the unit could cut out on
high head pressure. CAUTION: The fins on this condenser coil can be bent
very easily. If you use another type of brush make sure it is soft enough to
not damage the condenser. You can also blow out with compressed air.
