INSTALLATION
1. ENSURE THAT FIXING KIT HAS BEEN
LOCATED BEFORE DISPOSING OF
PACKAGING.
Remove the front panel by removing the
three screws along its bottom edge. With
hands positioned on each side of the panel,
lift upwards to unhook the top edge whilst
pressing down on the top panel with your
thumbs. The panel can now be lifted clear
and set to one side.
Remove the packing pieces from the slots
on the inner front (3 on the FXL18N and 4
on the FXL24N).
2. Remove the inner front panel by
unscrewing the screws along its top and
sides. As the front insulation is attached
care must be taken when lifting this panel
from the heater and placing it to one side.
Remove the three inner guards by
removing the screws along their bottom
edges and sliding the guards up and off
the base tray. Please note the location of
each guard.
3. CONNECTION OF THE MAINS CABLE
- Connect the restricted (E7) supply to the
terminal block, marked “Storage Circuit”,
having first passed the cable through a front
cable clamp in the base. Connect the
unrestricted (Peak) supply to the terminal
block, marked “Fan/Boost Circuit”, having
passed this cable through another cable
clamp in the base.
At this point, if desired, an external fan/boost
timer may be fitted to the heater by passing
the two wires from the timer through the
remaining cable clamp, and connecting
them across the terminal block, marked
“Timer”, having already removed the link
fitted across this block at the factory.
Connect the EARTH lead from both
supplies to the terminal marked with the
symbol
IMPORTANT DURING NORMAL OPERATION ENSURE
