a. Blue in color.
b. 1 to 4 inches (25mm to 102mm) above

Troubleshooting
9.1 General Heater Troubleshooting
The table on the following page lists some of the
more common problems, causes and solutions encoun-
tered when running the heater. Most problems occur
when the heater is being started for the first time after
installation or at Spring start-up. Careful installation
and maintenance will help ensure years of trouble free
use from your Lite2 pool heater.
9.2 LJ Controller Service Codes
9.2.1 Explanation of Service Codes
The LJ controller monitors several functions of
the heater. In the event of a malfunction, the controller
will display a service code where the inlet tempera-
ture is usually displayed and a service icon in the
middle of the display. See Figure 25 for appearance
and location of typical service code display.

10. Perform a temperature rise test in accordance
with Section 7.7.
11. Return the pool temperature control to the
desired temperature. Repeatedly depress the
MODE key until the indicator at the top of the
display shows 'POOL SET'. Then use the UP
and DOWN keys to set the heater to the desired
temperature.
Figure 25. Typical Service Code Display
The service codes are listed on the following
pages.
Only three of these service codes are reconcil-
able without the services of a qualified technician. The
first is the case where the heater does not start after
the first three attempts, FL2. This may occur after a
prolonged period of nonuse of the heater, especially at
Spring start-up. However, the repeated appearance of
this error requires the service of a qualified technician.
The second case is that of a temporary brown-
out condition, FL5. If the brown-out is regional, then
the controller will automatically reset when full power
is restored by the electric company. However, if the
brown-out is due to a low voltage supply problem only
on the heater circuit, then immediately shut off the
electrical supply to the heater and call a certified
electrician.
The last case is the filter is dirty condition, FL0.
