TEST
Test the Heat Trace Hose
NOTE
The heat trace hose is fitted with an integral thermostat that activates the heat trace
element at approximately 45oF (7.2oC). The hose temperature must be well below the
activation temperature before any test is performed.
1. Unplug the heat trace plug (1).
2. Use an ohmmeter or multimeter set to read ohms to check for continuity (resistance) at the between
the two flat prongs (2) of the plug (1). There should be continuity between the two flat prongs.
Replace a heat trace hose (3) with an open element. Refer to WP 0011 00 for installation
procedures.
3. Use an ohmmeter or multimeter set to read ohms to check for continuity (resistance) at the between
the each of the flat prongs (2) and the U-shaped ground prong (4). There should be no continuity
between the each flat prongs and the U-shaped ground prong. Replace a heat trace hose (3) with a
shorted element. Refer to WP 0011 00 for installation procedures.
4. If facilities are available to provide an ambient temperature greater than 60oF (15.5oC), allow the hose
to warm, then use an ohmmeter or multimeter to check for continuity (resistance) at the between the
two flat prongs (2) of the plug (1). There should be no continuity between the two flat prongs at
temperatures greater than 60oF (15.5oC). Replace a heat trace hose (3) with a shorted thermostat.
Refer to WP 0011 00 for installation procedures.
