Automatic
Float
Charging
Automatic
Float Charging
is ideal for m_intaining
a fully charged
battery.
1, Keep tile AC power and battery conrlected
after battery
is fully charged,
2. The chargel
monitols the battery and tops it off as needed.
3, The Float Charge indicator
lights; the display shows charge current when topping
off the battery and returns to "FUL" when completed,
4. To view battery voltage,
press tile Battery Voltage button.
Note: Charging can be termblated by pressing the charge rate selector button at any
time when unit is charging. After AC power interruption,
chargittg restarts at 4
amp
rate
automatically
and the
battery
type
will default to "GEL",
WARNING
if battery
size
is not
known,
charge
at
the
4 amp
rate,
DO
NOT
overcharge
batteries.
Equalizing
Equalizing
is the process by which the fluid in each of a battery's cells is equalized.
This process occurs after charging
is complete,
/_,_ W ARNINGS
* NEVER TRY TO EQUALIZE A GEL OR AGM
CELL. THE RESULTING
EXPLOSION
COULD CAUSE PROPERTY DAMAGE,
SERIOUS iNJURY
AND/OR
DEATH,
= Remove
or disconnect
the vehicle's
battery
when
equalizing.
The frequency wllich the equalization
process needs to be run depends on the use of
the battery. The more the battery is used, the more undercharged
it becomes; thus the
more frequently the battery should be equalized.
1. Do not use this mode on sealed or valve regulated
batteries, This mode is only
meant for wet (unsealed/vented)
batteries.
2. Make sure there are no flammable
sources near the recharging
sigllt.
3, Wear safety glasses, gloves and protective
clothing.
4. Remove battery
from vehicle.
MAKE SURE THAT THE BATTERY HAS GOOD
VENTILATION,
Tile process causes the release of hydrogen
and oxygen.
An
accumulation
of these gases presents a real danger of explosion.
5. Open the battery cap, if removable.
6, Fill the battery
with distilled
water according
to the manuf_]cturer's
instructions.
Since batteries may rapidly
bubble while being chalged,
remember to lefill (only
with distilled water) after the equalization
process is complete and the voltage
is
brick
tO nolrrlah
7, Follow the steps in the "Charging
the Battery" section on page 5 of this manual.
8. Push the Battery Type Selector Switch until "WET"
is displayed.
(This mode will
only work if a WET battery
is selected,)
9. Choose tlle correct charge
rate and start charging.
You can check the battery
voltage by pushillg the Battery Voltage button. This wil! trigger the Battery Voltage
indicator button.
10, Push the Equalize button at any time and the battery will automatically
begin to
equalize
in 4 amp limited current. Note that in order to push the recessed buuon
you will need a small pin or ballpoint
pen.
11, Every hour, the temperature
should
be checked
by touching
the battery.
If the
battery is hot to the touch, stop the charging
and allow the battery to cool,
12. The w)ltage
rises, but does ilOt go over
15.3v
to 16.2v
(2.55-2.7v
per cell)
depending
Ol_ ambient temperature;
it will automatically
adjust.
13. The "WET"
LED flashes while the charger
is in equalize
mode.
14. The digital
readout will show "FUL" whell the equalization
process is complete.
Engine
Start
Tile EHgine Start function can supply ! 10 amps for engine starting.
1, Set the 4/10/20/40
AMP button to 40 amp mode and immediately
pless the
110A
button switch to activate the Ellgille
Start mode.
2. The digital
display will countdown
from "999"
to "000."
3. When the "000"
count is reached and begins flashing oil the Display, the vehicle
is ready to start.
4. Crank the engine
using manufacturer's
guidelines,
typically
irl 3 to B second
bursts. The high current engine starting function requires a resting/cooling
period
between
tries.
The charger
will
switch
back to regular
charge
mode
aRel
5 seconds and will not allow operation
in this mode tot 4 minutes, Wait
4 to B
minutes before a second attempt at starting the engine, if needed.
5. During the rest period,
the battery
is charging
at 40 amps. After engine starts,
follow
the steps outlined
in "lmportarlt
Safety Instructions"
at tile front of this
manual to disconnect,
Recondition
Mode
Whenever
a lead-acid
battery begins to discharge,
lead sulfate, an insulator, begins
to build up on the battery's
internal plates. This reduces the ability
of tile battery to
hold a full charge.
When that battery
has an immediate
charge,
most of the lead
sulfate is dissolved
alld the plates are free of this illsulation.
If a bauery remains in a
discharged
condition
over a longer period
of time, the lead sulfate changes to a hard
clystalline
form, making a full charge difficult to achieve, Reconditioning
may "save"
a sulfated battery.
