GAW-135H — INSTALLATION

Outdoor Installation

Install the generator/welder in a area that is free of

debris

bystanders

, and

overhead obstructions

. Make sure the

generator is on secure level ground so that it cannot slide or

shift around. Also install the generator in a manner so that

the exhaust will not be discharged in the direction of nearby

homes.

The installation site must be relatively free from moisture

and dust. All electrical equipment should be protected from

excessive moisture. Failure to do will result in deterioration

of the insulation and will result in short circuits and grounding.

Foreign materials such as dust, sand, lint and abrasive

materials have a tendency to cause excessive wear to

engine and alternator parts.

Indoor Installation

Exhaust gases from gasoline engines are extremely

poisonous. Whenever an engine is installed indoors the

exhaust fumes must be vented to the outside. The engine

should be installed at least two feet from any outside wall.

Using an exhaust pipe which is too long or too small can

cause excessive back pressure which will cause the engine

to heat excessively and possibly burn the valves.

Eliminate the danger of deadly carbon monoxide gas.

Remember that exhaust fumes from any gasoline engine

are very poisonous if discharged in a closed room, but

harmless if allowed to mix with the outside air. If the generator

is installed indoors, you must make provisions for venting

the engine exhaust to the outside of the building.

Generator Grounding

To guard against electrical shock and possible damage to

the equipment, it is important to provide a good EARTH

ground. Always use the ground terminal on the generator to

ground the generator.

Article 250 (Grounding) of the National Electrical Code (NEC)

provides guide lines for proper grounding and specifies that

the cable ground shall be connected to the grounding system

of the building as close to the point of cable entry as

practical.

NEC articles 250-64(b) and 250-66 set the following

grounding requirements:

1. Use one of the following wire types to connect the

generator to earth ground.

a. Copper - 10 AWG (5.3 mm

) or larger.

b. Aluminum - 8 AWG (8.4 mm

) or larger.

2. When grounding the generator (Figure 3) connect the

ground cable between the lock washer and the nut on

the generator and tighten the nut fully. Connect the other

end of the ground cable to earth ground.

3. NEC article 250-52(c) specifies that the earth ground

rod should be buried a minimum of 8 ft. into the ground.

Mounting

The generator should always be mounted on a flat level

surface to isolate vibration of the generator when it is

running. DO NOT place the generator on slopes, the

possibility exists that the generator could slide.

Pay close attention to ventilation when

operating the generator inside tunnels and

caves. The engine exhaust contains

noxious elements.

CAUTIONCAUTION

CAUTION

An electric shock is apt to happen

when vibrators are used. Pay close

attention to handling when operating

vibrators and always use rubber

boots and gloves to insulate the

body from a short circuit.
