Oil Temperature Gauge (all sumps)
Mount the gauge on the pump operator's control panel where it will be easy to monitor.
•
The gauge connects to the larger of the two prongs on
the sender.
•
The smaller prong, which is labeled "WK", may be used
to activate an oil temperature warning light or alarm (not
provided). Pneumax recommends installing an over-
temperature device.
This prong is one side of a temperature sensitive switch
that will close at 250°F. The other side is grounded
through the metal of the sump.
The prong can be connected to the negative side of an
audible alarm or warning light.
•
Follow the installation instructions in the temperature
gauge box to connect the sender to the gauge and the
optional warning light.
