PERSONAL PRECAUTIONS
1. Someone should be within range of your voice or close enough
to come to your aid when you work near a lead-acid battery.
2. Have plenty of fresh water and soap nearby in case battery
acid contacts skin, clothing or eyes.
3. Wear complete eye protection and clothing protection. Avoid
touching your eyes while working near a battery.
4. If battery acid contacts skin or clothing, wash immediately with
soap and water. If battery acid enters the eye, immediately flood
the eye with running cold water for at least 10 minutes and get
medical attention immediately.
5. NEVER smoke or allow a spark or flame in the vicinity of the
battery or engine.
6. Be extra cautious to reduce the risk of dropping a metal tool
onto the battery. It might spark or short-circuit the battery or other
electrical part and cause an explosion.
7. Remove 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.
8. Use the battery charger for charging gel-cell or flooded lead-acid
batteries only. It is not intended to supply power to a low voltage
electrical system other than in a starter-motor application. Do not
use the charger for charging dry-cell batteries that are commonly
used with home appliances. These batteries may burst and cause
injury to persons and damage to property.
9. NEVER charge a frozen battery.
PREPARING TO CHARGE
1. Be sure the area around the battery is well ventilated.
2. Clean battery terminals. Be careful to keep corrosion from
coming in contact with eyes.
3. Add distilled water in each cell until battery acid reaches level
specified by battery manufacturer. This helps purge excessive gas
from cells. Do not overfill. For a battery without cell caps, carefully
follow manufacturer's recharging instructions.
4. Study all battery manufacturer's specific precautions such
as removing or not removing cell caps while charging and
recommended rates of charge.
GROUNDING AND A.C. POWER CORD CONNECTION
1. The charger should be grounded to reduce the risk of electric
shock.
(For marine applications only) EXTERNAL CONNECTIONS TO THE
CHARGER SHALL COMPLY WITH UL RECOMMENDATIONS AND/
OR UNITED STATES COAST GUARD ELECTRICAL REGULATIONS
(33CFR183, SUB-PART I)
(For marine applications only) THE INSTALLATION AND
PROTECTION OF VESSEL WIRING ASSOCIATED WITH BATTERY
CHARGERS SHALL COMPLY WITH ABYC STANDARDS; E-11) AC
& dc ELECTRICAL SYSTEMS ON BOATS, AND A-20) BATTERY
CHARGING DEVICES.

III) INSTALLATION
A) Materials Provided
The Phase Three charger is provided completely assembled and
ready for installation. Because of numerous installation variables,
the installer will need to provide four suitable 1/4" mounting
screws/washers, as well as D.C. output wiring and connectors.
Proper sizes and gauges for the wire and connectors are noted in
section D following. A warranty registration/customer satisfaction
card has been included in the packaging. Upon completion of
the installation, please fill out this card and return it to the factory.
You will be contacted promptly if you have any problems with or
questions about your Phase Three charger.
Note: AC & DC Present Alarm Contacts mating connector wire
assembly. Contact Newmar and request P/N 773-1210-0. See
section III-I for more information.
B) Location
The charger should be mounted on a wall, bulkhead or other
suitable mounting surface as close to the batteries to be charged
as possible. Do not mount the charger directly over the batteries
as battery fumes may cause excessive corrosion. WARNING:
The charger is not ignition protected so it must not be located
in an area where ignition protected equipment is required. The
area should be well ventilated and free from excessive moisture,
exhaust manifolds and battery fumes.
Vertical mounting is preferred. However, horizontal mounting is
acceptable where absolutely necessary. Do not mount the charger
where water, spray or condensation can occur, as this will shorten
charger life. It should not be located where there is a possibility
of dust or debris being drawn into the unit through the fan. A
minimum of 2" clearance around the charger is recommended for
proper cooling.
Installation of the drip shield is recommended for areas where
moisture or liquids could drip from overhead. The drip shield is
mounted using the upper two mounting screws.
If the charger is located in an extreme heat area, such as an
unventilated engine room, and maximum operating temperature
is exceeded, an automatic thermal shutdown circuit will turn the
charger off. Thermal cycling will shorten the life of the charger,
so if this condition occurs repeatedly, the charger should be
relocated. For optimum performance and longer life the charger
should not be located in an area of extreme high temperature.
C) Mounting
Important Pre-Installation Notes: The wiring access port for A.C.
input is located on the bottom of the charger. If the factory-installed
A.C. cord must be changed for any reason, this should be done
before mounting, as access will be difficult afterwards. Also, the
drip shield will need to be removed prior to setting the gel/lead
acid selector or installing the optional temperature compensation
probe. The drip shield is removable with the charger mounted,
but if there is limited overhead clearance the installer may wish
to accomplish these tasks also, prior to mounting the charger. For
information on these installation procedures refer to sections III-E, G
and H.
