2. Makesuresomeoneiswithinrangeofyourvoiceorclose
enough to come to your aid when you work with or near a
lead-acid battery.
3. Have plenty of fresh water and soap nearby for use if battery
acid contacts skin, clothing, or eyes. If battery acid contacts
skin or clothing, wash immediately with soap and water.
4. Avoidtouchingyoureyeswhileworkingwithabattery.Acid
particles(corrosion)maygetintoyoureyes!Ifacidentersyour
eye,immediatelyoodeyewithrunningcoldwaterforatleast
10 minutes. Get medical attention immediately.
5. Remove all personal metal items such as rings, bracelets,
necklaces, and watches when working with a lead-acid battery.
Alead-acidbatterycanproduceashort-circuitcurrenthigh
enoughtoweldaring(orthelike)tometal,causingasevere
burn.
6. Take care not to drop a metal tool or other metal onto the
battery.Metalmaycausesparkingorshortcircuitthebatteryor
another electrical device. Sparking may cause an explosion.
7. Alwaysoperatebatterychargerinanopen,well-ventilated
area.
8. NEVERsmokeorallowasparkorameinthevicinityofthe
battery or engine. Batteries generate explosive gases.
9. NEVERchargeafrozenbattery.
10. Alwaysunplugchargeraftereachuse.
WARNING: EXTERNAL CONNECTIONS TO CHARGER SHALL
COMPLY WITH THE UNITED STATES COAST GUARD ELEC-
TRICAL REGULATIONS (33CFR183, SUB PART1).
C. PREPARING TO CHARGE
1. If necessary to remove battery from boat or vehicle to charge,
alwaysremovegroundedterminalfrombatteryrst.Make
sure all accessories in the boat or vehicle are off, so as not
to cause an arc.
2. Cleanbatteryterminals.Takecaretokeepcorrosionfrom
coming in contact with your eyes.
3. If required, add distilled water in each cell until battery acid
reacheslevelsspeciedbybatterymanufacturer.Thishelps
purgeexcessgasfromcells.Donotoverll.Forabattery
without cell caps, carefully follow manufacturer’s recharging
instructions.
4. Studyallbatterymanufacturers’specicprecautions,such
as removing or not removing cell caps while charging, and
recommended rates of charge.
5. Be sure area around battery is well ventilated while battery
isbeingcharged.Usingapieceofcardboardorothernon-
metallic material as a fan can forcefully blow gas away.
D. CHARGER LOCATION
Donotrestricttheairowunderthecharger.Donotmountthe
charger next to fuel tanks or below the waterline of the boat.
The charger is waterproof and is approved for mounting on the
weatherdeck.
To allow for proper air circulation, a minimum of four inches of un-
obstructed area must be permitted on all sides of the charger.
Chosealocationsuchthatthesix-footcablescanreachthe
battery(ies).Ifextralengthisneeded,bringtheringlugstoa
terminalblockandextendwithaminimumof14AWGcables.
Chooselargerwireforextendedruns.
The charger weight is substantial. Ensure that the mounting sur-
faceisstrongenoughtosupportthecharger.Choosealocation
thatwillallowforallfourmountingholestobeused.Mountingwith
nuts, bolts and lock washers is preferable to screws.
Never place the charger directly above the battery being charged;
gases may harm the charger over time. Never allow acid to drip on
thechargerwhenreadingspecicgravityorllingbattery.
Do not set a battery or any other object on top of charger.
E. MOUNTING INSTRUCTIONS
The charger may be permanently mounted and connected. Four
mountingholeshavebeenprovidedforsecureinstallation.Choose
alocationforthecharger(see“CHARGERLOCATION”forproper
placement).Usingthechargerasatemplate,placethecharger
in the selected location and mark each of the four holes with a
pencil. In a well ventilated environment, drill the four holes using a
#9(7/32”)drillbitforusewithnutsandboltsORwitha5/32”drill
bit for use with #10 self tapping screws. Take caution of the area
on the other side that you are drilling to avoid drilling into wires or
othercomponents.Using#10bolts,nutsandlockwashers,mount
thechargerwiththeLEDsfacinguponaatverticalsurfaceto
allowforventilation.RoutetheACandDCcordstoeitherend
andavoidpinchingthemunderthebase.Asealantmaybeused
to waterproof the screw holes.
