PLEASE SAVE THESE IMPORTANT SAFETY AND OPERATING INSTRUCTIONS

For correct operation of the equipment, it is important to read and be familiar

with this entire manual before installing and operating the charger.

DO NOT DISCARD THIS MANUAL AFTER READING.

LOOK FOR THIS SYMBOL TO POINT OUT SAFETY PRECAUTIONS.  IT MEANS:

BECOME ALERT—YOUR SAFETY IS INVOLVED.  

IF YOU DO NOT FOLLOW THESE

SAFETY INSTRUCTIONS, INJURY OR PROPERTY DAMAGE CAN OCCUR.

INTRODUCTION

This battery charger is designed to recharge deep-
cycle, lead-acid batteries.  A ferroresonant
transformer is used to provide a highly reliable, line
compensating unit with a minimum of moving parts,
designed for long, trouble-free service.  A patented
electronic timer turns the charger on and off
automatically.  This electronic timer determines full
charge of the batteries by measuring the rate at
which the battery voltage increases during charge.
When the voltage stops rising, the battery is fully
charged and the charger turns off.

INITIAL INSTALLATION

The AC line to which the charger is to be connected
must be of the proper voltage as indicated on the
nameplate of the charger and in TABLE 1.  The line
must also be capable of supplying 15 amperes to
this charger.

CAUTION:  TO REDUCE THE RISK OF FIRE

USE THIS CHARGER ONLY ON CIRCUITS
PROVIDED WITH A MAXIMUM OF 20 AMPERE
BRANCH CIRCUIT PROTECTION (CIRCUIT
BREAKER OR FUSE), IN ACCORDANCE WITH
THE NATIONAL ELECTRICAL CODE, ANSI/NFPA
70, AND ALL LOCAL CODES AND ORDINANCES.

The use of an extension cord with the charger
should be avoided.

The use of an improper extension cord could result
in a risk of fire or electric shock.  If an extension cord
must be used, use a three-conductor, No. 12 AWG
cord with ground, properly wired, in good electrical
condition and keep it 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 subject to damage or
stress.

Do not operate this charger with a damaged cord or
plug.  Do not operate this charger if it has received a
sharp blow, was dropped or otherwise damaged in
any manner; refer to a qualified service agent.

Provide adequate ventilation for the 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") (5cm) away from walls and other objects.
Do not allow clothing, blankets, or other material to
cover the charger.

WARNING:  CHARGERS CAN IGNITE

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