Troubleshooting
Initial Troubleshooting
Only qualified, trained service technicians with appropriate test equipment should service the heater. Remember that all
parts of the system affect heater operation. Before starting this troubleshooting procedure, make sure that the pump is
running correctly, that there are no blockages in the system, that the valves are correctly set and that the time clock or
automation is correctly set and is running.
CAUTION: Installing the BLUE 120 volt plug in the control board and then connecting the heater to a 240 volt line
will destroy the transformer, control broad, and ignition control module, and will void the warranty. If you install
the RED 240 volt plug and then connect the heater to a 120 volt line, the heater will not operate.
READ THE FOLLOWING INFORMATION CAREFULLY
1. Check the line voltage to your heater. This heater will operate on either 120 Volts AC or 240 Volts AC.
2. Remove the covers and check the 12-pin plug in the back of the control box. The plug must match the voltage in
the heater circuit.
3. If the 12-pin plug is not plugged into the back of the control box, select the correct plug from the bag in the control
box and plug it in. The BLUE plug is for 120 volts, the RED plug is for 240 volts. See Figure 35 on page 42).
