CAUTION:  THIS CHARGER IS FOR USE

ONLY ON 12 CELL, 28-90 AMP-HR (20 HR.
RATE), 2.38-2.50 VOLTS PER CELL MAXIMUM
VOLTAGE RECHARGEABLE, DEEP-CYCLE
BATTERY SYSTEMS.  THIS CHARGER IS FOR
USE ON REPLACEABLE ELECTROLYTE OR GEL
CELL AND SEALED "MAINTENANCE-FREE"
DEEP-CYCLE BATTERIES.  "BATTERY TYPE"
SWITCH MUST BE SET TO THE PROPER TYPE
OF BATTERY.  BATTERIES IMPROPERLY
MATCHED WITH CHARGER MAY BURST,
CAUSING PERSONAL INJURY AND DAMAGE TO
BATTERIES OR CHARGER.

INITIAL INSTALLATION

Circuit breaker or fuse protection in the 120 volt AC
outlet to which the charger is to be plugged should
allow 5 amps per charger.  Do not overload electrical
outlet.  Use of an extension cord with the charger
should be avoided unless absolutely necessary.
Use of an improper extension cord could result in a
risk of a fire and electric shock.  If an extension cord
is needed, use a three-conductor, No. 16 AWG (or
larger) cord with ground, properly wired, in good
electrical condition and keep as short as possible.
Make sure that the pins on the plug of the extension
cord are the same number, size, and shape as that
of the plug on the battery charger.  Locate all cords
so that they will not be stepped on, tripped over, or
otherwise subjected to damage or stress.  Do not
operate the battery charger with a damaged cord or
plug.  Do not operate the battery charger if it
received a sharp blow, was dropped, or otherwise
damaged in any matter.  Refer to a qualified service
agent.

Provide adequate ventilation for both batteries and
charger.  The convection cooled design requires an
unobstructed flow of cooling air for proper operation.
Keep all charger ventilation openings at least two
inches (2") (5.08cm) away from walls and other
objects.  Do not allow clothing, blankets, or other
material to cover charger.  DO NOT PLACE UNDER
BED.

WARNING:  CHARGERS CAN IGNITE

FLAMMABLE MATERIALS AND VAPORS.  DO
NOT USE NEAR FUELS, GRAIN DUST,
SOLVENTS, THINNERS, OR OTHER
FLAMMABLES.

WARNING:  KEEP DRY; DO NOT EXPOSE TO

RAIN OR SPRAY.  FOR STORAGE, KEEP
CHARGER IN A BUILDING.  REPLACE WORN,
CUT, OR DAMAGED ELECTRICAL CORDS AND
PLUGS IMMEDIATELY.

AC INPUT

This battery charger must be grounded to reduce the
risk of electric shock.  It is equipped with an electric
cord having an equipment-grounding conductor and
a ground-type plug.  The plug must be plugged into
an appropriate outlet that is properly installed and
grounded in accordance with the National Electrical
Code and all local codes and ordinances.

DANGER:  IMPROPER CONNECTION OF THE

EQUIPMENT-GROUNDING CONDUCTOR CAN
RESULT IN RISK OF ELECTRIC SHOCK.  DO
NOT REMOVE GROUNDING PRONG FROM
PLUG.

GROUNDING INSTRUCTIONS

This battery charger is equipped with a grounding
plug as illustrated in Figure A, for use on a nominal
120 volt, 60 Hertz circuit.  A temporary adapter, as
illustrated in Figures B and C, may be used to
connect this plug to a two-pole receptacle as shown
in Figure B if a properly grounded outlet is not
available.  The temporary adapter should be used
only until a properly grounded outlet can be installed
by a qualified electrician.  The green-colored rigid
ear extending from the adapter must be connected
to a permanent ground such as a properly grounded
outlet box.

DANGER:  BEFORE USING THE ADAPTER

AS ILLUSTRATED, BE CERTAIN THAT THE
CENTER SCREW OF THE OUTLET PLATE IS
GROUNDED.

GROUNDING METHODS

NOTE:  Use of adapter shown in Figures B and C is

NOT permitted in Canada.

BATTERY TYPE

Battery manufacturers frequently use the same
battery cases for different battery types.
Replaceable liquid electrolyte deep-cycle batteries
have removable cell caps.  Water electrolyzed by
discharging and charging the battery is replaced
through these openings.
