Temperature Setting and Function Test
NOTE:
To perform this test you will need a thermometer and a water bath that can be
temperature controlled from 85 F to 95 F.
1.
Remove the temperature probe from the thermal well.
2.
Insert the end of the temperature probe into the 85 F water bath that without
submerging beyond the threads.
3.
Allow the probe to acclimatize for a minimum of 5 minutes.
4.
Slowly increase the water bath temperature until the monitor indicates (red light)
“RO Unit Interlock”. Check the water bath temperature with a thermometer for
90 F
±
1 F. Adjust the set point as required.
NOTE:
The set point is adjusted through the hole on the left side of the monitor with a
screwdriver. Clockwise rotation reduces the temperature set point and counter clockwise
will increase the temperature set point.
5.
Check that the RO unit shuts down at the alarm set point.
6.
Switch the Override Switch on the monitor from normal run to the Override
position. The RO unit should start up and the Override indicator lamp will light.
7.
Switch the Override Switch from the Override position to the normal run position.
The RO unit should stop running if the temperature is over the set point of 90 F.
8.
Slowly reduce the water bath temperature until the Monitor’s temperature
switches from the alarm condition to normal operation. The RO unit should
return to normal operation.
9.
Log all set point and calibration data.
10.
Replace the temperature probe into the thermal well.
