9.1 Basic Checks
Visual inspection of the heater base and accessories should be performed monthly. Check the temperature probe sensors,
temperature sensor cables, all unit cables and connectors, and the power cord. Damaged items should be replaced if
necessary. For complete maintenance information, contact your sales provider.
9.2 Dual Temperature Probe Check
It is recommended that the dual temperature probe be functionally tested on a routine basis (every 6 months) to ensure
that it is operating properly.
The following method is recommended:
1
Obtain a precision thermometer or other temperature measuring device accurate to /-0.5
°
C.
2
Place the thermometer (or equivalent device) and both of the temperature sensors into a container of
warm water (between 25
°
C and 45
°
C).
3
Allow time for equilibration of the thermometer and the dual temperature probe. Connect the dual
temperature probe to the heater base as recommended and turn the unit on. Compare temperature
readings. The display should be /-1.5
°
C of the thermometer. If not, probe should be replaced.
