Facility Water
Strainer
The facility water strainer is the user-installed basket strainer on the
FACILITY WATER inlet.
NOTE:
The strainer is designed to be used only
with water. Clean the strainer when it becomes visibly clogged or dirty.
Disconnect the power cord from the power source and turn off the facility
cooling water.
Place a container under the strainer to collect any water that spills out of the
basket when it is removed.
Unscrew the clear plastic basket. Remove the screen and rinse it with water.
Replace the screen and the basket.
Algae
To restrict the growth of algae in the reservoir, it is recommended that the
reservoir cover be kept in place and that all circulation lines be opaque. This
will eliminate the entrance of light which is required for the growth of most
common algae.
Fault Interlock
Contact
A set of contacts is connected to a receptacle on the control panel. The
contacts are rated 10A/240V. This is not a power inlet or outlet. The
receptacle is isolated from the circuitry. Its ground pin is connected to the
chassis. The contacts are closed during normal operation and open when
the unit is turned off or when a fault is detected.
