ace in order to keep
the apparatus free from dirt and moisture. To avoid acid fumes, do not
place the Tungar directly over the batteries. These precautions will
prevent corrosion of the metal parts and liability of poor contacts.

Fasten the Tungar to a wall by four screws, if the wall is of wood, or
by four expansion bolts if it is made of brick or concrete.

Though the electrical connections of the outfit are very simple, it is
advisable (when installing the apparatus) to employ an experienced
wireman familiar with local requirements regarding wiring.

Line Connections

The two wires extending from the top of the Tungar should be connected
to the alternating current supply of the same voltage and frequency,
as stamped on the name plate attached to the front panel. These
connections should be not less than No. 12 B. & S. gauge wire and
should be firmly soldered to the copper lugs.

External fuses are recommended for the alternating-current circuit, as
follows:

With 115-volt line use 15-ampere capacity fuses.

With 230-volt line use 10 ampere capacity fuses.

One of the bulbs (Cat. No. 189049) should now be firmly screwed into
its socket. Squeeze the spring clip attached to the beaded cable and
slip this clip over the wire protruding from the top of the bulb. Do
not bend the wire.

Battery Connections

In making battery connections have the snap-switch in the "Off"
position.

The two wires extending from the bottom of the Tungar should be
connected to the batteries. The wire on the left, facing the front
panel, is marked + (positive) and the other wire - (negative). The
positive wire should be connected to the positive terminal of the
battery and the negative wire to the negative terminal.

The two flexible battery cables are sometimes connected directly to
the two wires projecting from the bottom of the Tungar. These cables
should be securely cleated to the wall about six inches below the
outfit. This arrangement will relieve the strain on the Tungar wires
when cables are changed to different batteries.

When two or more batteries are to be charged, they should be connected
in series. The positive wire of the Tungar should be connected to the
positive terminal of battery No. 1, the negative terminal of this
battery of the positive terminal of battery No. 2, the negative
terminal of battery No. 2 to the positive terminal of battery No. 3,
and so on, according to the number of batteries in circu
