Condition
Recommended Corrective Action
Unit will not start.
•
Check power source. Ensure that the source voltage matches the unit’s
specified voltage.
•
Wait five (5) minutes after last power shut down before restarting.
Unit will not cool.
•
Ensure that the unit has adequate airflow. Air is pulled from the left side of
the unit to cool the refrigeration system components and then exits the rear
panel.
•
Verify that the Chill light is illuminated.
•
Ensure that unit has been positioned with a minimum of six (6) inches of
clearance on all sides to maintain proper airflow and avoid damage to the
refrigeration system.
Compressors will not start.
•
Wait five (5) minutes after last power shut down before restarting. The
CharpyCool™ should never be restarted immediately after it is powered off.
The refrigeration system compressor is equipped with a sensor designed to
prevent the low-stage compressor from starting within several minutes of a
loss of power, intentional or unintentional (
e.g.,
power switched off, facility
power outage, loss of main power, etc.).
Magnetic stirrer does not
rotate.
•
The driving magnet for the stirrer is located under the bath. This magnet is
driven by a toothed drive belt, which is attached to a motor. Check the drive
belt for proper tension. It is possible for the drive belt to tighten or loosen
during shipment.
To check the drive belt for proper tension:
1.
Switch off the unit.
2.
Unplug the unit and remove the cover.
3.
Ensure that the drive belt has slight tension.
To adjust the tension of the drive belt:
1.
Loosen the drive motor mounting nuts and slide the motor until the belt shows
slight tension (
i.e.,
3/8- to 1/2-inch of play). The drive belt is toothed, and therefore,
does not require full tension for operation.
2.
Retighten the mounting nuts once you have corrected the drive belt tension, and
replace the cover.
Magnetic stirrer making noise.
•
Ensure that the stirrer is centered in the bath and that the holding screws on
the magnetic stirrer are snug. Refer to Chapter 2, Installation, for more
information.
