Testing above Freezing Temperatures

Under normal operating conditions the heaters will be turned on at a water temperature between 40° and 45°F, and turned off when the water temperature exceeds 45°F. For testing the system at temperatures above 45°F there are two methods as follows:

Method A

1.Disconnect power to the control panel using standard lockout proce- dure for safety.

2.Remove the panel cover

3.Remove the sensor wires connected to terminals T1 and T2 on the relay circuit board.

4.Connect a 1.5K ohm resistor (included in panel) across T1 and T2 terminals—see Figure 2.

5.Replace panel cover and verify probe is submerged in tower basin water.

6.With panel cover in place turn on power supply to the system. An au- dible CLICK should be heard as the contactor engages. If this does not happen, refer to the Troubleshooting section of this manual.

7.If the system tests OK turn off power, remove the panel cover and re- move the resistor. Replace sensor wires T1 and T2 and replace the cover.

Turn system on.
