• The instrument and any thermometer probes used with it are sensitive in-
struments that can be easily damaged. Always handle these devices with
care. Do not allow them to be dropped, struck, stressed, or overheated.
COLD BATHS
• Refrigerated baths require that the condensing coil be cleaned periodi-
cally. Accumulation of dust and dirt on the condenser will result in pre-
mature failure of the compressor.
• Bath or compressor lifetime may be affected by:
♦
♦
• This bath has been equipped with a brownout and over voltage protection
device as a safety feature to protect the system components.
• Mode of Operation: This bath needs to be plugged into the line voltage
for at least 2 minutes before operation. This is only necessary for the first
time that the bath is energized or when it is moved from one location to
another. Turning the bath ON or OFF does not trigger the delay.
• If a High/Low voltage condition exists for longer than 5 seconds, the bath
de-energizes. The display flashes "LoLinE" while the contdition exists.
• Re-energization is automatic upon correction of the fault condition and af-
ter a delay cycle of about 2 minutes. If a fault condition exists upon appli-
cation of power, the bath will not energize.

Cycling the heat source through extreme temperature ranges (the full
temperature limit of the heat source). Cycling the instrument can cause
excessive stress on the compressors. Compressor manufacturers rec-
ommend, for longest lifetime, that the instrument be set at one temper-
ature and left on at that temperature.
Turning the instrument on and off frequently adds wear and tear to the
compressor.
