Installation

Set this unit as you would any other high power battery
charger. Fit it as close to the starter batteries as possible
in a cool, dry and well ventilated space. As with the most
ideal conditions on a boat, the cool well ventilated part is a
bit of wishful thinking. With this in mind you may notice that
the unit comes with a heat sink and a cooling fan.

If you have to fit it in a hot engine room then it should be
okay but try to fit it low down on the bulk head as it will be a
little cooler there than at the top of the engine room.

Wiring, refer to simple diagram on previous page (page x):
connect  the  output  positive  cable  first  (to  the  house  /
domestic,  for  example).  Then,  the  input  positive  cable
(starter  battery),  then  the  negative  (common  negative).
Remember the unit is voltage sensitive. Thus, If the input
voltage  is  above  13.3V  (due  to  alternator,  generator  or
charger) the unit shall start and begin boosting - you can
eliminate  the  voltage  sensitive  aspect  by  adding  an
ignition  fed  cable  (refer  to  next  page  for  operational
modes) .

Setup routine:

1) All LEDs will come on to confirm the LEDs are okay.
2)  The  fan  will  ramp  up  in  speed  to  confirm  the  speed
control is okay.
3) All LEDs and fans off.
4)  Blue  LED  will  flash  1-9  times  to  show  what  the  unit
battery chemistry is actually set to (depending on battery
type as per label). If you are happy with this setting then do
nothing,  if  you  are  not  happy  then  simply  wait  and  the
yellow LED will start to flash.
5) The yellow LED flashes (for approximately 5 seconds),
then,  during  this  time  frame  you  must  start  the  battery
chemistry  adjustment  procedure  using  the  magnetic
swipe area in the lid of the unit (read below for additional
information).  This  is  the  only  window  of  opportunity
available to adjust the battery type on the unit. After the
yellow  light  stops  flashing  the  unit  is  locked  into  that
battery type. If you fail to set the product up to the correct
battery chemistry the first time and need to try again, do
not worry. To reset the system to try again, simply remove
the positive input cable or the negative cable (i.e. "kill the
power to the product") and on re-attachment the startup
procedure  will  start  again.  Do  this  as  many  times  as  it
takes to get the correct battery chemistry setting.

Programming the battery chemistry type for the
output battery (typically house, domestic, auxiliary)

During setup procedure the yellow LED will fast flash for 5
seconds, during this time is your window of opportunity to
adjust the battery type. With the lid removed and in your
hand  swipe  the  magnet  (built  in)  against  the  area  as
marked  on  the  drawing.  Simply  hold  the  lid  magnet
against  the  box  in  this  area.  if  you  have  made  correct
contact  with  the  magnetic  internal  switch  (during  the  5
seconds the yellow is flashing) the yellow LED will go off
and the red LED will flash ( hold this area ) this shows you
have "hit the spot" ( magnetic switch ) and you are now
ready to adjust.

Please note, as soon as you do this, any pre-stored
battery type setting is removed and we start from
battery type 1 (GEL USA refer to table on the RHS).

To adjust, remove the lid from the magnetic swipe area,
the  red  light  will  go  out  (  to  show  you  have  lost
attachment with the reed switch) and the blue LED will
flash once. This shows the unit is now set to battery type
Re-swipe the magnet, for the second time, and the red
LED will come back on. Remove the magnet and wait,
the blue LED will flash twice. You are now on battery
type 2 (AGM see below). Continue this procedure until
you  reach  the  number  of  flashes  you  require.  On
reaching  your  number  then  simply  wait  about  15
seconds and wait for the unit to show 2 LEDs (green and
red) and it will lock that setting. The unit then restarts the
start  up  sequence  which  will  show  the  new  battery
setting  (number  of  blue  flashes). At  this  point  yellow
flashing  LED  will  come  on  and  you  are  given  the
opportunity to adjust, if still not correct. If content, then
ignore, leave alone and allow the setup to complete and
the unit shall store the settings.

1) Select the battery type on your auxiliary battery
system. The input battery chemistry is of no relevance
to this process.

Remember

it is the voltages which are more important

than our battery types. After installation test the voltage
from the unit is the desired voltage.

Ensure you

remove at least 1 wire from the battery temperature
sensor as the product voltage may be higher ( if in
cold climate ) or lower ( if in warn climate ) than the
pre conceived voltage.

The voltage requirements of

the battery company will override our recommendations
as it is them who are supporting the battery warranty.
