dust does not build up on the fins hampering the efficiency of the bath, i.e.
month, bi-monthly. Use a vacuum or cloth to clean the fins.
• If a hazardous material is spilt on or inside the equipment, the user is re-
sponsible for taking the appropriate decontamination steps as outlined by
the national safety council with respect to the material. MSDS sheets ap-
plicable to all fluids used in the baths should be kept in close proximity to
the instrument.
• If the mains supply cord becomes damaged, replace it with a cord of the
appropriate gauge wire for the current of the bath. If there are any ques-
tions, call an Authorized Service Center (see Section 1.3, on page 5) for
more information.
• Before using any cleaning or decontamination method except those rec-
ommended by Hart, users should check with an Authorized Service Cen-
ter (see Section 1.3, on page 5) to be sure that the proposed method will
not damage the equipment.
• If the instrument is used in a manner not in accordance with the equip-
ment design, the operation of the bath may be impaired or safety hazards
may arise.
• The over-temperature cutout should be checked every 6 months to see that
it is working properly. In order to check the user selected cutout, follow
the controller directions in Section 9.2, Reset Cutout, for setting the cut-
out. Both the manual and the auto reset option of the cutout should be
checked. Set the bath temperature higher than the cutout. Check to see if
the display flashes cutout and if the temperature is decreasing. Note:
When checking the over-temperature cutout, be sure that the temperature
limits of the bath fluid are not exceeded. Exceeding the temperature limits
of the bath fluid could cause harm to the operator, lab, and instrument.
• When using silicon oil, the bath will require periodic maintenance. The
silicon oil will condense on the bath during normal operation due to the
outgasing of the oil. How often and how long the bath is operated at
higher temperatures determines how often the maintenance will have to
be performed. Simply wipe down the oily areas of the bath with a mild
degreaser such as 409®. Do not spray the degreaser directly on the bath.
Spray the degreaser on a cloth and wipe the bath down with the cloth. Re-
peat the process as often as necessary to keep the oil from collecting on
the bath. If oil is allowed to collect on the bath, it may run into the bath
and collect on the interior of the bath causing internal damage that may
affect the lifetime of the instrument.
