ATTENTION
Ne tentez pas d'effectuer des réparations au
système de régulation du débit du gaz ou à
l'appareil. Toute modification non autorisée est
dangereuse et entraîne l'annulation de toutes
les garanties.
CAUTION
Keep all objects off the top of the heater.
Blocking air flow could damage the heater, and
may void the warranty.
ATTENTION
Ne posez aucun objet sur le dessus de
l'appareil. Il pourrait empêcher la circulation de
l'air, ce qui risquerait d'endommager l'appareil
et d'annuler la garantie.
WARNING
Vent pipes, draft hoods, and heater tops get
hot! These surfaces can cause serious burns.
Do not touch these surfaces while the heater is
in operation. Adding a vent cap reduces the
temperature on the top.
AVERTISSEMENT
Les tuyaux d'aération et le dessus de l'appareil
deviennent chauds! Ils peuvent causer de
graves brûlures. Ne touchez pas à ces
surfaces lorsque l'appareil est en marche.
WARNING
For your safety, when starting the heater, keep
your head and face well away from the lower
firebox opening to prevent any risk of personal
injury.
AVERTISSEMENT
Pour votre sécurité personnelle lorsque vous
mettez l'appareil en marche, tenez votre tête et
votre visage loin du brûleur pour éviter tout
risque de blessure.
7.2 Setting the LJ Controller Functions
and Limits
The LJ controller is a microprocessor based
controller designed to control various functions of your
pool and spa water circulation system. It provides a
visual display of the status of the heater and pump
functions. It has a built-in time clock that eliminates
the need for an external clock to control the pump. It
even provides information in the form of service codes
used to diagnose a problem in the event of a malfunc-
tion. The pressure sensitive push-button keypad and
large LCD display make the controller easy to pro-
gram and use.
When the LJ controller is powered for the first
time, it recognizes that the installation is new and uses
all the internal default values for control. On initial
start-up and any time the power to the heater has been
interrupted and then reestablished, the firmware
revision will flash for one second on the display screen
where the time is normally displayed. After one
second, the display will show the time if the controller
is in the "Internal Time Clock" mode or three dashes
(– – –) if in the "External Time Clock" mode (see
Section 7.4, "Heater/Control Operation").
The following sections explain how to set your
heater control to your preferences. After programing
the controller for the first time, all settings and modes
will remain in memory until changed. Even if the
power to the heater is interrupted, the settings will not
have to be reprogrammed. If the pump and heater
were ON when the power went off, they will be ON
when power is restored to the heater.
If the controller is in the "Internal Time Clock"
mode, the only indication that power to the heater has
been interrupted and the 'real time' clock needs to be
updated is that the clock will be flashing on the display.
When power is restored, the clock will remember the
time when the power went off and resume from that
point on. Therefore, the clock will have to be reset.
Refer to Figure 18 to identify the location of keys and
display items mentioned in the following sections.
NOTE: All of the functions and limits of the LJ
controller can be reset to the original
manufacturer's default values by pressing and
holding the ENTER key for 7 seconds.
